Synthetic microphone storehouse is to optimize sealing and mechanical attributes
In the consumer-elcetronics devices such as portable computing device, the SoundRec ability is quite general.So equipment typically comprises the microphone of a certain type.Usually, microphone uses in voice application, such as digital telephone, IP phone (VOIP) and voice memo.The videograph that microphone also can write down view image and sound at the same time uses in using.
Microphone can be positioned in the inner space of electronic equipment.For example, in having the portable computing device of housing, be provided with the built-in microphone that is configured to receive sound via the hole in the housing.Can be separated by a distance between built-in microphone and the hole.So the microphone storehouse can be used to provide the sound tube between hole and the built-in microphone.
In portable computing device, can expect to avoid by inside produce or sound by wherein with mix via the sound that the hole the housing enters the microphone storehouse from external source.For example, if equipment comprises internal loudspeaker, the sound compacting that then can expect to avoid being produced in inside by loudspeaker is by the sound of microphone through the generation of the outside of microphone storehouse reception.In addition, under the situation that the sound that generates in the outside that enters the microphone storehouse and other source of sound acoustics are isolated, method that then can more easy use such as echo cancelltion.In telephone communication, echo cancelltion has been described and removed the process that echo is improved the voice quality of call thus from voice communication.The echo cancelltion application can be known acoustic enviroment, such as the acoustic enviroment in the microphone storehouse, and easier being determined under this situation of being isolated by acoustics in the microphone storehouse.
The acoustics of inside, microphone storehouse is isolated and can be formed the microphone storehouse by the material by relative sound insulation and realize by provide good air-tightness to seal at two ends, microphone storehouse.Sealing integrity can be influenced by one or more materials that are used to form the microphone storehouse and the method that is used for fixing the microphone storehouse.For example, the microphone storehouse can so that pressure maintained that sealing is gone up and help thus to keep the every end in microphone storehouse seal sealing integrity mode and be fixed.
Sealing integrity can be subjected to forming the influence of relative hardness of the material in microphone storehouse.The advantage of relatively hard materials is and can provides good platform for set up sealing at the every end in microphone storehouse place.The outside generative power of the power that generates when the inferior position of relatively hard materials is its easier will falling such as equipment is delivered to device interior.If the power by the transmission of microphone storehouse is excessive, then might damage the internal part of portable computing device.In view of above-mentioned, microphone as described below storehouse design will utilize the advantage of the improved sealing property that relatively hard materials can provide, and take into account simultaneously and the shock transfer attribute that uses relatively hard materials to be associated.
In more detail, referring to Figure 31 A-36C, the synthetic microphone storehouse than the combination of soft material that can utilize the relatively hard materials selected at its sealing property and select at its damping performance has been described.But those skilled in the art will recognize easily that this paper is for task of explanation with reference to the given detailed description of these accompanying drawings, and should not be construed as restrictive.More specifically, will describe use hard and than the embodiment in the synthetic microphone storehouse of the combination of soft material with reference to figure 31A-31C.With reference to figure 32A-32B, the example of incorporating into as several installation sites in the synthetic microphone storehouse of a microphone assembly part has been discussed.In Figure 33 A-33B, then show microphone assembly at pre-installation and installed position.Between installation period, the microphone storehouse can be fixed to push the mode of improving sealing integrity thus.To the transmission of operating period external force by the microphone storehouse be described with reference to figure 33C.With reference to figure 34A-43C, the different embodiment in the synthetic microphone storehouse that comprises various dimensions and material are discussed.The method of making the portable computing device that comprises synthetic microphone storehouse has been described with reference to Figure 35.At last, 36A-36C has discussed the skeleton view and the block diagram that can comprise the portable computing device that synthesizes the microphone storehouse with reference to the accompanying drawings.
Figure 31 A-31C shows and comprises microphone 3106, circuit board 3104 and such as the microphone assembly 3100 in the microphone storehouse of 3102a, 3102b and 3102c.Microphone 3106 is shown as and is coupled to circuit board 3104.In a particular embodiment, circuit board can be formed by rigidity or flexible substrates.Microphone storehouse such as 3102a, 3102b and 3102c then can comprise each surface that centers on chamber 3112.Chamber 3112 can be used as sound tube.For example, as mentioned above and will be described in further detail with reference to figure 32A and 32B, in portable computing device, chamber 3112 can be coupled to hole in the housing by acoustics, sending into the sound tube of built-in microphone as the sound of the source generation that portable computing device is outer.
The microphone storehouse can comprise inner surface profile and outer surface profile.Inner surface profile provides the boundary of inner chamber 3110a.Shown in Figure 31 A, microphone storehouse 3102a is columniform.In this example, outer surface profile 3108a and inner surface profile 3110a can roughly be described as two concentric cylinders.Top surface 3111 and the basal surface of microphone storehouse 3102a can general planar.
The inner surface profile in microphone storehouse and outer surface profile are not to be made of concentric shape.Generally speaking, outer surface profile and inner surface profile can differ from one another, and can be shaped to have the shape that can change from the top surface to the basal surface arbitrarily separately.For example, chamber 3112 can be wideer and narrower in the bottom at the top.In addition, chamber 3112 can have a kind of shape and have another kind of shape in the bottom at the top.In addition, in a specific embodiment, the crooked route by inside, microphone storehouse can be followed in chamber 3112.
For example, the outer surface profile microphone storehouse 3102b different with inner surface profile has been shown among Figure 31 B.Microphone storehouse 3102 comprises the outer surface profile 3108b of columniform inner surface profile 3110b and rectangle.In another example, this shape profile can be just in time opposite, so that inner surface profile 3110b is a rectangle and outer surface profile 3108b is cylindrical.Be similar to the example of Figure 31 A, top surface 3111 and basal surface are smooth.
In each embodiment, one of the top surface in microphone storehouse and basal surface or both can be crooked.For example, in Figure 31 C, show the microphone storehouse 3102c that comprises crooked top surface 3111a and emerge.Microphone storehouse 3102c comprises the inner surface profile 3110c of rectangle and the outer surface profile 3108c of rectangle.
In certain embodiments, the top surface in microphone storehouse (such as 3111a) can combine with the crooked inner surface of apparatus casing.In order to improve sealing integrity, useful is the top surface of shaping such as 3111a, so that its curvature is complied with the curvature of shell inner surface more or less.For example, the top surface bending will obtain more equal top surface pressure distribution with the inside surface of complying with housing, improve sealing integrity thus.In other embodiments, the microphone storehouse that has planar top surface can be bonded to crooked inner surface, and the microphone storehouse that perhaps has crooked top surface can be bonded to flat inner surface.In this embodiment, the smooth or crooked top surface in microphone storehouse can use force of compression (that is, by compression microphone storehouse) to make to comply with inside surface.
In Figure 31 A-31C, the top surface of microphone 3106 is shown as microphone storehouse smooth and that have an emerge and is shown as with the planar top surface of microphone and combines.In other embodiments, the top surface of microphone 3106 can tilt or be crooked, then can tilt as required to comply with the top surface of microphone more or less such as the basal surface in the microphone storehouse of 3102a, 3102b and 3102c.As mentioned above, the sealing integrity between the top surface of the basal surface in microphone storehouse and microphone can be improved in the microphone storehouse that is shaped in this way.
In other embodiments, the top surface of the basal surface in microphone storehouse and microphone can differently be shaped.For example, the top surface of microphone can be crooked, and the basal surface in microphone storehouse can be smooth.The bottom in microphone storehouse can be made by compressible material, and when the emerge in microphone storehouse was pressed against on the curved surface of microphone, the emerge in microphone storehouse can be complied with the crooked top surface of microphone thus.
As mentioned above, microphone assembly can be installed in equipment (such as, portable computing device) inside.Microphone assembly and the microphone storehouse that is associated thereof can be positioned so that it aligns with the hole in the housing, and provide sound tube between hole and microphone.The hole can be positioned at each position on the outside surface of equipment.The layout in hole can influence the position and the orientation in microphone storehouse.Followingly will two examples that have the microphone assembly of different orientations in the band portable computing device be described with reference to figure 32A and 32B.
In Figure 32 A and 32B, comprise that the microphone assembly in microphone 3106, circuit board 3104 and microphone storehouse 3102 is shown as housing 3120 inside that are positioned at portable computing device.Housing 3120 is roughly rectangular.The outside surface of housing 3120 comprises outer surface profile 3120a and inner surface profile 3120b.Outer surface profile 3120a and inner surface profile 3120b can be shaped with differing from one another.For example, outside surface 3120a can be smooth in a zone, and corresponding interior zone then is crooked.Near the microphone storehouse inner surface configuration can influence the sealing integrity of the seal between microphone storehouse and the inside surface.As mentioned above, in certain embodiments, the top surface in microphone storehouse can be shaped to comply with the shape of shell inner surface, improves sealing integrity thus.Sealing integrity is important, because good gas-tight seal can help the acoustics of the sound tube of inside, microphone storehouse to isolate.
In Figure 32 A, microphone storehouse 3102 is shown as upwards directed, and aligns with housing along axle H from top to bottom in the chamber in the microphone storehouse.In this embodiment, the top cover such as lid glass can be placed on the opening of housing 3120.An embodiment of the portable computing device of the housing that comprises body glass with cover has been shown among Figure 36 A.Top cover can comprise the hole.Between installation period, microphone assembly is disposed in the housing, makes the top surface in microphone storehouse and hole in the top cover be in it and aligns the position the during installation site.Subsequently, when top cover was mounted, the basal surface of top cover can combine with the top surface in microphone storehouse, generated sound tube via the microphone storehouse between the hole of top cover and microphone thus.
In another embodiment, can comprise the hole 3122 that is used for such as 3106 microphone such as 3120 housing.In Figure 32 B, housing 3120 is shown near the sidepiece of its corner has hole 3122.Microphone 3106 is shown as the location so that the top surface of microphone is roughly parallel with sidepiece with holes with circuit board with circuit board 3104, and the opening in microphone storehouse 3102 aligns with this hole.The sound tube that is associated with the microphone storehouse is roughly alignd with axle W.
Other orientations in microphone assembly and microphone storehouse also are possible, and are not limited to the orientation shown in Figure 32 A and the 32B.For example, in one embodiment, the top surface in microphone storehouse 3102 can combine with near the shell inner surface the hole 3122, to form sound tube.Subsequently, can adjust the orientation of circuit board and microphone, so that microphone storehouse and internal pipeline thereof are slight curving in some way.The microphone storehouse can be by the flexible material structure to realize bending.Might not wish that the microphone storehouse is crooked above a certain definite limit, thereby avoid the possible hoop of microphone storehouse internal sound pipeline disconnected.
In other embodiments, can provide crooked microphone storehouse.For example, can construct the microphone storehouse that is similar to pipe bend.Can provide this pipe bend by the curved shape of a certain angular bend with ancon.Crooked microphone storehouse can allow the oriented phase of microphone and printed circuit board (PCB) to change for housing, and this may expect for the encapsulation reason.Followingly will the more details that microphone storehouse 3102 are attached to housing 3120 be described with reference to figure 33A and 33B.
Figure 33 A-33B shows the side view that is in the microphone assembly of pre-installation site and installation site in housing respectively according to described embodiment.In Figure 33 A, show the sectional view in microphone storehouse 3102.Hole 3121a in one end in microphone storehouse 3102 and the housing 3120 aligns, and second end in microphone storehouse then aligns with microphone 3106.So, form sound tube via the microphone storehouse between hole 3121a and the microphone 3106.
First seal 3122 can form between the top surface of the basal surface in microphone storehouse 3102 and microphone 3106.3124 of second seals can form between the inside surface of the top surface in microphone storehouse 3102 and housing 3120, so that the hole of this microphone storehouse in the housing 3120.In one embodiment, first seal and second seal use the bonding agent such as contact adhesive (PSA) to form.PSA can provide as double faced adhesive tape.In another embodiment, first seal 3122 or second seal 3124 can use liquid adhesive to form.
In one embodiment, microphone 3106 and circuit board 3104 can be provided for the microphone storehouse 3102 that has been attached to microphone 3106.In another embodiment, during device assembles, microphone 3106 and circuit board 3104 can be used as the parts that separate with microphone storehouse 3102 and provide.Under the situation that microphone storehouse and microphone provide as separate parts, microphone storehouse 3102 can at first be attached to microphone 3106, and is being attached to the inside surface of housing 3120 subsequently, and perhaps vice versa.Attach procedure can relate on each end in microphone storehouse arranges other sealed binder of PSA or some.
After aliging with the hole 3121a of housing and form initial the combination between microphone storehouse and enclosure interior in microphone storehouse 3102, can apply force of compression to the microphone storehouse, such as 3130a and 3130b.Force of compression can be in microphone storehouse 3102, generate when microphone 3106 and circuit board 3104 fix in position.For example, can use such as one or more securing members of screw circuit board 3104 is fixed near other structure of housing 3120 or some.In place along with screw can generate force of compression on microphone storehouse 3102.Force of compression can be used to any air pocket around seal is extruded, thereby can improve the sealing integrity of seal.
Shown in Figure 33 A, housing 3120 can be crooked near microphone storehouse 3102.So force of compression can distribute unequally by the microphone storehouse.For example, will be in the force of compression on the sidepiece 3114a in microphone storehouse less than the force of compression on the sidepiece 3114b in the microphone storehouse.As mentioned above, in certain embodiments, microphone storehouse 3102 can be shaped to the force of compression that distributes more equably.For example, the top surface in microphone storehouse can tilt, and follows the curvature of the inside surface of housing 3120 thus.In other embodiments, the curvature that the top surface in microphone storehouse 3102 can not followed shell inner surface (for example, top surface can be smooth and inside surface can be crooked, shown in Figure 33 A), and force of compression can be used for oppressing the top surface distortion in microphone storehouse, thereby makes it comply with the inside surface of housing.
Height 3135 between the position of circuit board 3104 and housing is shown in Figure 33 A.After the installation, as shown in Figure 33 B, height 3135 can change.For example, height 3135 can reduce, and this can reduce with the height in microphone storehouse 3102 to be associated.The size that the amount that microphone storehouse height reduces can depend on its original size, be used to form the material in microphone storehouse and impose on the force of compression in microphone storehouse.
The bulging force 3140 that reduces to cause being transferred to the microphone storehouse of microphone storehouse height.Bulging force 3140 can push against seal 3122 and 3124, thereby can improve the sealing integrity of seal.For example, as mentioned above, force of compression can help to remove air pocket.The improvement of sealing integrity can realize the more excellent isolates sound characteristic of microphone storehouse internal sound pipeline.For example, along with seal becomes more airtight, can reduce the sound that penetrates into the microphone storehouse via the sound channel of housing 3120 inside.In one embodiment, the isolation of the acoustics in the sound tube in microphone storehouse can be about 40dB even bigger.
Figure 33 C shows the side view that applies the microphone assembly in the housing 3120 of power 3142 in response to the outside.Operating period, can stand the power that the outside applies such as the equipment of portable computing device, such as 3142.For example, equipment may fall, thus generative power.
The power that the outside applies can transmit by this equipment via various paths.Power such as 3142a can transmit by microphone storehouse 3102, then can be sent in microphone 3106 and the circuit board 3104 such as the power of 3142b.Power can transmit with dynamical fashion.For example, the microphone storehouse can be compressed, and can cause the change of height 3135c subsequently in response to power expands.The expansion in microphone storehouse and shrink can each inter-module of push-and-pull attached, attached such as between the seal 3122 and 3124 of microphone 3106 and circuit board 3104 and every side.
If the microphone storehouse is not appropriately designed, the expansion in microphone storehouse 3102 and contraction and might cause deterioration so such as the sealing integrity of 3122 or 3124 seal such as the bending of the miscellaneous part of circuit board 3104.In test, at some microphone storehouse design, find that the seal such as 3122 or 3124 can be drawn back, microphone 3106 can break away from from circuit board 3104, and perhaps circuit board can be damaged.In one embodiment, microphone assembly can designed to be able to and bear the acceleration that reaches 10000g ' s, and this has arranged the outside amplitude that applies power.
Test period find to use by softer and more compressible single microphone assembly of planting the microphone storehouse that material forms, and than the microphone storehouse that is formed by hard material more, (such as the vibrations that caused by unexpected acceleration) have higher resistibility to shock damage.Yet also finding can provide better sealing integrity, and provide better acoustics to isolate thus by singly planting microphone storehouse that hard material more forms than the microphone storehouse that is formed by soft material more.Yet, use the microphone assembly in the microphone storehouse that forms by hard material more to be easier to be given a shock infringement.
In order to utilize more the antidetonation attribute of soft material and the improved sealing property of hard material, can provide the design of synthetic microphone storehouse.The combination of hard material and soft material can be used in synthetic microphone storehouse.Relatively hard materials can be used for improving sealing integrity, then can be used for improving shock resistance than soft material.The following embodiment that has described the synthetic microphone storehouse of in microphone assembly, using with reference to figure 34A-34D.
Figure 34 A-34D shows sectional view such as 3200,3225 and 3235 synthetic microphone storehouse according to preferred embodiment.Top seal and lower seals are shown on each microphone storehouse and form.At Figure 34 A, show the top view in the microphone storehouse 3200 that comprises seal 3202a.Top view shows microphone storehouse 3200 and comprises circular open 3210 to internal path 3215, to form the sound tube by the microphone storehouse.The packing ring that is similar to seal 3202a can form at the top in microphone storehouse 3200.As mentioned above, inner surface profile and the outer surface profile such as 3200 microphone storehouse can change along with internal path.So the top view in microphone storehouse can depend on for outline and the selected surface topography of interior profile and changes.Seal 3202a can be designed to almost cover the top surface in microphone storehouse 3200.So the shape of seal 3202a can correspondingly change.
Return Figure 34 A, the microphone storehouse can comprise the first terminal cap moiety 3204a.The first end cap 3204a can be formed by first material, and has first thickness 3212.Hermetic unit 3202a can combine with the top of the first end cap 3204a.The second end cap 3204b can be positioned on the bottom in microphone storehouse.Second end cap can be formed by second material, and can have second thickness 3216.Thickness is that the centering portions 3206 in 3214 microphone storehouse can be placed between the first end cap 3204a and the second end cap 3204b.Centering portions can be formed by the 3rd material.First thickness 3212, second thickness 3216 and the 3rd thickness 3214 can differ from one another.
Hermetic unit 3202b can be bonded to the second end cap 3204b.As previously mentioned, hermetic unit 3202a can be bonded to a surface, such as the inside surface of housing.Hermetic unit 3202b can be bonded to a surface, such as the top surface of microphone.Hermetic unit 3202a and 3202b can be formed by identical or different material.For example, hermetic unit can or have two kinds of different PSA to form by identical PSA.
In a particular embodiment, second material that is used for first material of the first end cap 3204a and is used for the second end cap 3204b can be selected according to the ability that they improve sealing integrity, and the 3rd material of centering portions 3206 then can be selected according to its damping performance.As mentioned above, use hard material can improve the sealing integrity that is associated with microphone storehouse seal (such as 3202a and 3202b), use the shock resistance that then can improve microphone assembly than soft material.So the material of selecting to be used for first end cap and second end cap can be formed to improve sealing integrity by relatively hard materials, centering portions then can be by forming to improve shock resistance than first end cap and the softer and more compressible material of second end cap.In one embodiment, first end cap and second end cap can be formed by duroplasts, and centering portions can be formed by the softer plastics of ratio end cap such as silica-based plastics.
In a specific embodiment, the first end cap 3204a and the second end cap 3204b can be made by first relatively hard materials, and centering portions then can be made than soft material by second.She Ji microphone storehouse is can be during the dijection Shooting Technique whole in this way forms, and wherein uses first material in a shot and use second material in biphasic injection.First material and second material can be selected so that two materials are combined together during the dijection Shooting Technique.In other embodiments, the first end cap 3204a, the second end cap 3204b and centering portions 3206 can be formed respectively, such as die-cut, and are being bonded together in some way to form the microphone storehouse subsequently.
In one embodiment, the first end cap 3204a and the second end cap 3204b can have the shape about equally of same thickness.Yet the thickness 3214 of centering portions can be different.In other embodiments, first end cap and second end cap can differently be shaped.For example, in Figure 34 B, show the first end cap 3228a and the variform microphone of second end cap 3228b storehouse 3225.The microphone storehouse comprises centering portions 3230, and can select to be used for the material of centering portions 3230, the first end cap 3228a and the second end cap 3228b, thereby improves sealing integrity and/or shock resistance in aforesaid mode.
The top surface of the first end cap 3228a can be by crooked or inclination someway.As mentioned above, the shape that can expect the first end cap 3228a roughly comply with its will in conjunction with the surface.For example, the shape of the first end cap 3228a can be complied with the crooked inner surface of housing, shown in Figure 33 A-33C.Seal 3226a and 3226b can be bonded to the first end cap 3228a and the second end cap 3228b respectively.Seal can be shaped to follow its will in conjunction with the surface.So seal 3226a can be crooked, to follow the shape of the first end cap 3228a, seal 3226b then is flat relatively, to follow the flat shape of bottom end cap 3228b.
In Figure 34 A and 34B, show the centering portions 3206 and 3230 in microphone storehouse with relative constant thickness.In other embodiments, the thickness of the centering portions in microphone storehouse can change.For example, in Figure 34 C, show the microphone storehouse 3235 of the variation in thickness of centering portions 3240.The microphone storehouse can comprise first end cap 3238a that has inclined upper surface and the second end cap 32238b that has planar bottom surface.Seal 3236a and 3236b can be attached to corresponding end cap respectively.Thickness at the second end cap 3238b shown in this example is constant relatively.
In Figure 34 C, the thickness of centering portions 3240 can be from thick attenuation.In addition, the thickness of first end cap 3238 then can be in the thickening of the place of centering portions 3240 attenuation and at the local attenuate of centering portions thickening.In other embodiments, interface between the centering portions 3240 and first end cap 3238a level and second end cap relatively can be made into thinner or thicker, so that the interface between the centering portions 3240 and the second end cap 3238b tilts, allow the variation of centering portions thickness profile thus.In another embodiment, the interface between interface between the first end cap 3238a and the centering portions 3240 and centering portions 3240 and the second end cap 3238b can all tilt in some way.
The thickness of the centering portions 3240 in microphone storehouse can change, and changes the distribution of microphone storehouse force of compression in it when being mounted thus.For example, the thickness of centering portions 3240 can change with the more uniform compression force distribution of generation, and the end cap that is provided as thus such as 3238a provides better sealing.In other embodiments, it is thicker or thinner that centering portions 3240 can be done in the specific region, to adjust these regional shock absorption properties.In some embodiment again, it is thicker or thinner that centering portions can be done in the specific region, generating preferred vibrations transmission path, such as the guiding vibrations away from more fragile regional and towards the path in more structure-reinforced zone.

Figure 45 shows the extended view according to the top perspective view of the modularization material antenna module of an embodiment.Herein, antenna flexible cable 4222 has been mechanically secured to the top of antenna block 4208.As shown in figure 44, can use the screw 4224 that enters support 4218 that antenna flexible cable 4222 is fixed to antenna block 4208.Should be noted that support 4218 needs not to be the assembly that separates with housing 4200, in fact, in one embodiment, whole support 4218 and the housing 4200 of forming.Antenna flexible cable 4222 also can be electrically connected to the circuit board (not shown) of consumer products, and the electric assembly on the circuit board can additionally be electrically connected to housing 200, so that with each assembly ground connection.
In addition, antenna block 4208 can be grounding to housing 4200.In an example, can use power spring (being called as ground spring) to carry out this task.This spring self can have the shape with the counterpart interlocking of antenna block 4208 and housing 4200, so that fix this ground spring.This spring is designed to elastic deformation, this can reduce collide with or other damage to the influence of consumer products.Even the elastic deformation of spring can allow in drop event or between other this impact epoch, spring also is maintained between antenna block 4208 and the housing 4200.
Have given shape though antenna block 4208 is shown as in Figure 42-45, antenna block generally needn't form with any specific shape.In fact, the shape of antenna block can change based on some different factors, and described factor comprises that the easiness of easiness, installation of the design of adjacent structure and shape, structure and antenna block will be fixed to the firm degree on the framework.Framework and antenna block mode interlocked with one another also can influence antenna performance, and thinks that making interlocking portions with the material with differing dielectric constant has further improved above antenna performance.In other words, the interlocking aspect of differing dielectric constant material has improved above antenna performance, and has exceeded the performance that may occur when connecting the differing dielectric constant material under not having the situation of interlocking portions.
In addition, the shape of antenna block can change the wireless receiving characteristic of equipment.Some shape and/or size may increase or reduce wireless receiving usually.In addition, some shape and size can increase wireless receiving when using equipment in some mode, and reduce wireless receiving when otherwise using equipment.Position when for example, user's hand is being in one's hands equipment can change the wireless receiving characteristic of equipment.Provide bigger space between the housing parts of position that can be by holding equipment usually antenna block and user, or reduce or eliminate this influence by placing nonconducting physical buffer material (such as rubber buffer).So, antenna block can be designed to all above-mentioned factors of big as far as possible efficient way balance.
Antenna block, framework and housing can use the treatment process that is fit to arbitrarily to be made by the material that is fit to arbitrarily.This can comprise, for example, and metal, synthetic material, plastics etc.Can use the method that is fit to arbitrarily to make these assemblies, such as for example, shaping, forging, extruding, machining, die casting, punching press and any other suitable manufacturing treatment process or its combination.

The PCB that forms
Have display and expect the factor that at first will consider in the encapsulation of portable computing device of slim profile be big parts in the housing (such as, display, display circuit and battery) layout.In addition, also need to consider to be used for fixing these than the support of large equipment parts and/or the layout of attachment structure.Than the location of large equipment parts and supporting structure thereof also should consider need for the various I/O mechanism that arranges around the housing outer rim (such as, volume switch, power knob, data and power connector and audio jack etc.) enough spaces are provided.In the remaining space that is not occupied, then can arrange other internal parts (such as, but not limited to processor and storer, loudspeaker, microphone, camera and associated circuit board thereof) and allow all devices parts can its desired function and all kinds of connectors of Be Controlled and operation by big parts.
The remaining space that is occupied by big parts can not distribute with irregular shape, different position and height levels in shell.The parts that can design special shape are to fit in these spaces.Subsequently, each parts can be coupled to each other in some way.For example, provide its desired function in order to allow portable set, many parts can with controller board (such as, main logic plate) communication, to receive operational order.Other lifts an example, and many parts need electric power, and this then can be connected via various power supplys by internal cell provides.Typically, the space between each parts can be used to route data and/or power supply connection.So, need consider in the package design of equipment that power supply is connected required space with data.

Battery 6130 can be positioned in the centering portions of housing.In one embodiment, battery 6130 can have make the inner space near the battery top can with, inner space near the battery bottom can with and inner space location and the size that can use along the battery side.MLB6105 can be so shaped that the 6105a of first can fit in the inner space near the battery top, and second portion 6105b can fit in the inner space near the battery bottom.Connector part 6105c can connect the 6105a of first with second portion 6105b mutually.Connector part 6105c is thinner longer than first 6105a and second portion 6105b.Connector part 6105c is shown as the internal path wiring along battery 6,130 one sides.
Shape and the position of the 6105a of first, second portion 6105b and connector part 6105c only provide for illustrative purposes, but not are used for restriction.In each embodiment, the 6105a of first of MLB6105 and second portion 6105b can be than the greater or lesser sizes that has shown in the figure.In addition, the 6105a of first can have the shape and size different with second portion 6105b.Similarly, can be non-rectangle such as the shape of each part of 6105a and 6105b, and can comprise curved surface when needed.In addition, the PCB such as MLB6105 can comprise two or more major parts.For example, the flexible PCB such as MLB6105 can comprise three major parts that connect mutually by two connector parts.
In each embodiment, connector part 6105c can be attached to major part 6105a and 6105b at diverse location.For example, connector part 6105c can be attached near the central authorities of part 6105a and part 6105b, to form " I " shape.In this example, if if having internal path can with or the shell of battery 6130 can comprise that then this connector 6105c can be routed on the top or bottom of battery 6130 as the groove of the path of connector 6105c at its top surface or basal surface.
Connector 6105c need not to form straight line.For example, connector 6105c can be formed to follow crooked route or to follow a plurality of straight line line segments (for example, step or Z-shaped path) each other in different angles.In another example, connector 6105c can comprise one or more branches.Branch can be connected to other circuit, such as additional PCB.Following will further describing with reference to figure 62C and 64B-65E, after connector 6105c forms, this connector 6105c can be bent or be reversed into the various specific internal paths that are configured to follow.For example, following will further describing with reference to figure 62C, connector 6105c can be bent to pass the differing heights in the equipment.
Figure 62 B shows the cross section with constant width value vertical with the cross section of Figure 62 A.MLB6105 can be positioned at height 6152 places under battery 6130 tops.The 6105a of first of MLB and second portion 6105b can have the size in the free space between the bottom side of the top side that can be fitted to battery 6130 and battery 6130.Connector part 6105c can pass the side that connects battery bottom side and top side, as shown in phantom in FIG..
In one embodiment, as shown in Figure 62 B, MLB6105 can stride PCB with a constant relatively height and install in a planar configuration, and promptly 6105a, 6105b and 6105c install with similar height.In other embodiments, MLB can install in non-planar configuration.For example, in Figure 62 C, the 6105a of first can be installed in height on the top of battery 6130 and concordant with display 6104, and second portion 6105b then is installed in the height place under the top of battery.Connector part 6105c then passes the difference in height between 6105a of first and the second portion 6105b.
In Figure 62 A-62C, show the embodiment of the flexible PCB that is configured to MLB6105.For illustrative purposes, the big top surface area of MLB6105 is shown as the basal surface installation that is roughly parallel to apparatus casing.In other embodiments, flexible PCB can be installed to be the bottom (referring to accompanying drawing 63A) that makes bigger top surface area be approximately perpendicular to apparatus casing.In other embodiment, the first of flexible PCB can be installed to be and make its basal surface with housing parallel, and second portion can be installed to be the bottom vertical that makes itself and housing.For example, in Figure 62 A, part 6105a can be installed to be roughly parallel with the bottom of housing, and roughly the basal surface with housing is vertical so that this connector 6105c can be installed to be and connector 6105c can be bent to a right angle.Vertical orientation can only be described for illustrative purposes.Setting angle such as each part of the flexible PCB of MLB6105 can change, and is not limited to relative to each other or is vertical orientation with respect to each dimension of housing install.
Figure 63 A show the big surf zone of PCB roughly with the configuration of the bottom vertical of housing 6100 in the skeleton view of flexible PCB6160.At bending position not, PCB6160 is roughly a rectangle band, and this illustrates for the illustration purpose, and can utilize other shapes.The top view of the PCB6160 under the bending position and backplan be not shown in accompanying drawing 63B and the 63C.At Figure 63 A, PCB6160 centers on the corner bending to fit in the space between part of appliance 6165 and the housing 6100.Part of appliance 6165 can be 1) inherent structure, such as the part of the framework that is used for fixing other internal parts; 2) be installed in the part of the part of appliance (such as battery) in the housing; Or 3) above-mentioned combination.
Assembly process, PCB6160 can be provided as flat band, and can be bent and/or be torqued in the space of expectation subsequently, such as the space between part of appliance 6165 and housing 6100 around corner.In one embodiment, the material of PCB6160 can be configured to make it not keep its curved shape.So PCB6160 may need to be fixed, so that it remains in the bending position shown in Figure 63 A.
For example, for PCB is fixed on curved shape, PCB6160 can be attached to the side of sidepiece or the bottom and/or the part of appliance 6165 of housing 6100.Other lifts an example, if place the space of PCB6160 enough narrow (such as, the space between part of appliance 6165 and housing 6100), then PCB6160 is bent and in the space of slipping into expectation subsequently at assembly process.The bending moment (that is, if not constraint, it is straight that this PCB6160 will become) that is accumulated among the PCB6160 can force the side in PCB6160 opposing space, and can help thus to be fixed in its space that has been placed.
In another embodiment, PCB6160 can be provided as flat band at assembly process.Yet PCB6160 can be configured to make its maintenance or part to keep crooked shape afterwards.PCB6160 can be configured to make its in the specific region (such as, be designed to crooked zone) in easier bending, and in other zones (such as, be designed to smooth zone) in then harder.Following will be with reference to the accompanying drawings 66A and 66B describe in more detail to form have the PCB(of variable durometer attribute such as 6160) details.
In yet another embodiment, PCB6160 can form with its curved shape before assembling.For example, PCB6160 can be molded into curved shape.In another example, PCB6160 can form even shape, but is manufactured into curved shape subsequently before the assembling of portable computing device.So, can provide the PCB6160 of curved shape to be used for assembling process.
In each embodiment, PCB6160 can comprise and only is attached to the PCB6160 top side, only is attached to PCB6160 bottom side or be attached to the parts of PCB6160 top side and bottom side.Attached parts can extend on each surface of PCB6160.Can according to PCB6160 be in its during the installation site free space in the housing come the alternative pack position.In addition, can come the alternative pack position based on being desirably in the last location of PCB bent position.In certain embodiments, expect some parts is attached as away from being intended to be enough to crooked zone, this is because crooked meeting damages the attached of parts or parts and PCB6160.

For example, because connector assembly 7118 can be accepted aerial lug (for example, 30 pin connectors), therefore when connector engaged with connector assembly 7118, the major part of second audio port 7122 can blocked or obstruction.In this case, the user of personal media device 7100 unlikely can hold housing 7102 in a kind of mode of stopping up or hindering first audio port 7120.Therefore, even the existence that the connector that engages could stop up or hinder second audio port, 7122, the first audio ports 7120 substantially also can help keep the general perceives audio output level by output at least some sound from the passive sub-audible sound that is redirected to first audio port 7120 of second audio port 7122.
Figure 73 shows the viewgraph of cross-section of the mancarried electronic aid 7100 shown in Figure 71-72.Housing 7102 can surround various internal unit parts, and permission personal media device 7100 operations that for example are associated with user interface are used for the parts of its predetermined function.For discussing purpose, can think that the internal unit parts are disposed in a plurality of layers that pile up.For example, the display screen of display module 7104 can be located immediately at the below of top glass 7106.In one embodiment, display screen and related display driving circuit thereof the part that can be used as display module 7104 is encapsulated in together.What be in display module 7104 belows can be circuitry 7130, the main logic plate or the circuit that for example are associated with miscellaneous part, and the battery 7132 that is used for providing to personal media device 7100 electric power.
Inner frame 7140 can increase the overall hardness of personal media device 7100 by the ability that for example strengthens the bending moment that opposing housing 7102 bears.This inner frame 7140 can be made with multiple firm and flexible material.For example, when inner frame 7140 was made by the metal of stainless steel and so on, inner frame 7140 can be called as the M(metal)-framework 7140.M-framework 7140 not only can be for personal media device 7100 provides structural support, but also can be used for helping the heat with various internal parts generate to be sent to external environment condition.M-framework 7140 can be positioned at the below of display module 7104 and the top of circuitry 7130.In this way, M-framework 7140 can provide support for various internal parts, and helps to send the heat from the internal part of display module 7104 and so on.
M-framework 7140 can be as the attachment point of other parts of appliance.For example, M-framework 7140 can or use bonding agent and is attached to installation surface 7134a and 7134b on the housing 7102 via fastener.Then, other parts of appliance of display module 7104 and so on can be coupled to M-framework 7140, rather than are directly coupled to housing 7102.Display module 7104 is via the advantage that M-framework 7140 is coupled to housing: display 7140 can be isolated slightly with the bending moment that is associated with housing 7102, that is, the bending moment that generates on the housing can be dissipated to M-framework 7140.By display module and the bending moment that is associated with housing 7102 are isolated, can prevent to damage display module 7104, the generation of for example breaking.
Should be noted that in certain embodiments, personal media device 7100 can comprise additional inner frame.For example, framework 7150 can directly be fixed to housing 7102, and can be used to support top glass 7106 usually.In this regard, framework 7150 can be called as G(glass)-framework 7150.In order to support lid glass 7106, G-framework 7150 can comprise the edge 7152 with flange portion, and wherein lid glass 7106 is bonding with edge 7152 around flange 7154, seals entire equipment thus.G-framework 7150 can be made with non-conductive frame material, for example glass filled plastics.An example about the glass filled plastics that is adapted in the G-framework 7150 using is by Alpharetta, the KALIX that the Solvay Advanced Polymers of GA makes TMKALIX TMThe high performance nylon that comprises 50% glass fiber reinforcement.It will be recognized by those of ordinary skills, have a lot of other potential frame materials also to be fit to use with this embodiment, unless and spell out, claim should be construed to is to be limited to KALIX TMOr other any glass filled plasticses.
Figure 74 shows the zoomed-in view of the part 7200 of housing 7102 shown in the Figure 72 that sees from the front.At the remainder of this argumentation and do not lose generality, first audio port 7120 will be called as housing port 7202, the second audio ports 7120 and then be called as connector port 7204.Housing port 7202 can have size and the shape that conforms to outward appearance with the overall shape of housing 7102.For example, the sidewall 7206 of housing 7102 can have batten or curved shape, and this helps the user that personal media device 7100 is held in the hand.Correspondingly, housing port 7202 can be shaped to the shape that is easier to sidewall 7206 and coordinates mutually.Housing port 7202 can be positioned at the position with rear surface 7208 standoff distances " d " of housing 7102.Housing port 7202 adopts a kind of like this mode to dispose, and shown in Figure 75, the sound 7210 that sends from housing port 7202 can be directed the rear surface 7208 of housing 7102 with angle θ.In this way, when being placed on personal media device 7100 on the support surface S, the sub-audible sound of sending from housing port 7,202 7210 can be directed with the angled θ of surperficial S, thus with at least some sound guidances in the sub-audible sound 7210 to support surface S.In this way, support surface 7210 can be served as soundboard, so that at least a portion sound in the sub-audible sound 7210 can be by support surface S reflection, the sounding audio-frequency of robust presents thereby produce more.
Figure 76 shows the view according to the interior section 7500 of the personal media device 7100 of description embodiment.Shown in Figure 76, M-framework 7140 can be used to various internal parts to provide support, for example sub-audible sound maker assembly 7504 and connector assembly 7506.In described embodiment, sub-audible sound maker assembly 7504 can be fixed to housing 7102 by G-framework 7150 and M-framework 7140.Connector assembly 7506 can be installed to printed circuit board (PCB) (PCB) 7508 by veneer.Sub-audible sound maker assembly 7504 can comprise the audio amplifier 7510 with first 7512 and second portion 7514.First 7512 can comprise being arranged to provides the sub-audible sound of sub-audible sound 7518 maker unit 7516.First 7512 can be configured to provide first air path 7520.First air path 7520 can be via housing port assembly 7522 acoustics coupling sub-audible sound maker unit 7516 and housing port 7202.In this way, the first 7524 of sub-audible sound 7518 can use first air path 7520 via housing port assembly 7522 and housing port 7202 and be delivered to external environment condition from sub-audible sound maker unit 7516.
Second portion 7514 can be integrally formed with first 7512.Second portion 7514(is also referred to as " sidecar (side car) " part) can be configured to provide second air path 7526.Second air path 7526 can be via connector assembly 7506 acoustics coupling sub-audible sound maker unit 7516 and connector port 7204.In this way, the second portion 7528 of sub-audible sound 7518 can use second air path 7526 and be delivered to external environment condition from sub-audible sound maker unit 7516 via connector port 7204.In order to ensure firm attachment sub-audible sound maker assembly 7504, can use fastener 7530.Fastener 7530 can be diversified.Fastener 7530 can adopt the form that sub-audible sound maker assembly 7504, M-framework 7140 and connector assembly 7506 is fixed to the screw 7530 of housing 7102.
Adopt first air path 7520 to have plurality of advantages with the existence of at least two parallel air path of second air path, 7526 forms.This class advantage is: the existence of at least two air path can reduce the overall impedance to air-flow, reduces the loss amount of sub-audible sound energy in the course of normal operation thus.In this way, can listen efficient (that is the sound sensed level at given volume input level place) greatly to improve.In addition, by provide at least two can be for the parallel air path of the sub-audible sound 7518 that generates by sub-audible sound maker unit 7516 along its propagation, any increase to flow impedance in air path can partly compensate by another air path that passively air-flow is redirected to the littler impedance air path of expression at least.In this way, even an audio output port partly even is fully stopped up, the output sound level of perception will can significantly not reduce.In this way, the described maintenance that presents of the audio frequency that personal media device 7100 is provided can significantly improve user's perception of the audio performance of personal media device 7100.
For example, when sub-audible sound maker unit 7516 was just providing sub-audible sound 7518, first 7524 can be delivered to housing port 7202 via first air path 7520.The second portion 7528 of sub-audible sound 7518 can be delivered to connector port 7204 via second air port 7526 simultaneously.When by user's perception, sound sensed level on housing port 7202 and connector port 7204 (that is acoustic energy level) is roughly the same.What in other words, overall audio frequency perception will cause the hearer to infer that sub-audible sound 7210 is actually from single position rather than send at least two positions.Yet, if for example the user will point or other objects are placed on the position of stopping up or hindering housing port 7202, will enlarge markedly the flow impedance in the air path 7520 so, cause the significantly reduction of housing port 7202 place's acoustic energy output quantities thus.In this case, the impedance to air-flow that meets with at first air path, 7520 places increases can cause passively that at least some sound in the first 7524 are redirected to second air path 7526 from first air path 7520.In this way, even the acoustic energy output quantity at housing port 7202 places significantly reduces, the acoustic energy output quantity at connector port 7204 places also can be redirected to second air path 7526 passively and increased substantially from first air path 7520 because of acoustic energy.Thus, the overall audio output level of perception (that is audio volume level) can keep constant substantially.
Thus, the general integrity of obvious first air path 7520 and second air path 7526 is very important for the above-mentioned advantage that is retained to small part (particularly about the perception of the audio balance between audio frequency efficient, each output port and keep whole acoustics to experience).For example, in air path, can both reduce the overall audio frequency efficient of sub-audible sound maker assembly 7504 to any systemic increase of flow impedance.For example, second air path 7526 directly is connected to external environment condition via connector port 7204.In order to prevent to reduce the quality (for example owing to the accumulation of dust increases impedance to air-flow) of air path 7526, can between connector port 7204 and second portion 7514, place filtrator 7532 from the intrusion of the dust of external environment condition and other foreign material.Filtrator 7532(is as being shown in further detail hereinafter and discussing) can be used for preventing that the foreign material of sealing and dust and so on pollute second air path 7526.In addition, in described embodiment, filtrator 7532 can be firm but accessible, is provided at the ability of periodically clearing up filtrator 7532 under the situation that does not cause damage for the user thus.In addition, foam seal 7533 and foam seal 7535 can be applied to housing port 7202 and connector port 7204 simultaneously.The foam seal 7533 that is used for sealing gland housing port 7202 can adopt the thicker relatively froth bed and the form of ornamental mesh, and foam seal 7535 then can take to use the form of the foam ring of overlap joint on connector port 7204.
In a useful especially embodiment, filtrator 7532 can adopt the form that can be placed on the ornamental/hydrophobic mesh heap 7532 in the air path 7526.When being placed into air path 7526, ornamental/hydrophobic mesh heap 7532 can prevent moisture and dust intrusion personal media device 7100.Mesh heap 7532 can comprise a plurality of layers, and this wherein comprises the mesh layer at least.The mesh layer can provide an ornamental screen cloth, and it can prevent from directly to see from external environment condition the inside of personal media device 7100.Usually, the mesh part of mesh heap 7532 can be made with coarse and waterproof materials.In some cases, mesh material can be enough firm, so that provide at least some structural support for connector port 7204.The intensity of ornamental mesh can be enough big, so that opposing is by for example object being inserted into the infringement that causes in the connector port.
Except the protection of avoiding dust and moisture intrusion being provided and protecting the inside of personal media device 7100, it is accessible that described mesh also keeps, so that implement cleaning and foreign material removing.The accessibility of mesh is very useful, because the gathering of dust or other foreign material is clearly on the mesh heap 7532.The gathering of mesh place dust or other foreign material is very tedious, because the pollutant of dust and so on can focus on the mesh place and hinder the output of sub-audible sound, reduces the overall performance of personal media device 7100 and total user experience thus.By the burnisher of wet cotton rod of simple insertion and so on, just can remove on the mesh such as the foreign material of dust, prevent that thus described sealing from being filled up and voice output reduces.
Can be used to help to keep the integrality of second air path 7526 such as the feature of sealing gland 7534.Engaging between the rear portion that sealing gland 7534 can be used to hermetically sealed connector assembly 7506 and the second portion 7514.Sealing gland 7534 can be made by any suitable compatible material with appropriately sealed characteristic.For example, sealing gland 7534 can adopt the form of foam seal 7534.Because foam has compressive characteristics, foam seal 7534 can compress (shown in Figure 77) in place between the adapter 7538 of the adapter 7536 of second portion 7514 and connector assembly 7506.In described embodiment, adapter 7536 can be shaped according to adapter 7538, and adapter 7536 can closely be combined thus.In this way, the spatial accommodation inside that is provided by adapter 7538 can closely be provided adapter 7536.
In assembling process, sub-audible sound maker unit 7504 can use tilting action to be placed on housing 7102 inside.This tilting action can make adapter 7536 enter adapter 7538 obliquely and be held by it, can exert pressure this moment to second portion 7514, and 7514 of described second portions can connect sub-audible sound maker unit 7504 and be fixed to connector assembly 7506 and PCB7508.Enter and exert pressure by inclination, adapter 7536 can compression adapter 7536 and adapter 7538 between foam seal 7534, make the significantly compression of foam seal 7534 experience.In described embodiment, adapter 7538 can be shaped in a kind of mode of the compression of foam seal 7534 experience of emphasizing, greatly strengthens the ability that foam seal 7534 stopped or at least obviously suppressed moisture or other pollutant invading air paths 7526 thus.The register pin that is associated with second portion 7514 can tilt to insert use in the processing.This register pin has shape and the position that is configured to insert the accommodation hole among the PCB7508.Because PCB7508 and connector assembly 7506 are welded together during reflow treatment, so register pin can also keep second portion 7514 in position so that second portion 7514 become can't with connector assembly 7506 delamination.
In addition, keep feature 7540 can be used for further guaranteeing the sealing gland integrality of second air path 7526.Keep the feature 7540 can adaptive M-framework 7140, and in case in place, just prevent that adapter 7536 from separating with adapter 7538.Correspondingly, M-framework 7140 is placed on the top of connector assembly 7506 and audio amplifier 7510.M-framework 7140 can comprise the finger piece that is suitable for putting into maintenance feature 7540, and in one embodiment, described maintenance feature can be positioned at the shell part of connector assembly 7506.M-framework 7140 can also comprise spring clamp, and the latter can load the side of second portion 7514 towards connector assembly 7506.The power of creating by spring clamp can cause sealing 7534 at the joint of adapter 7534 and adapter 536 by overcompression.Therefore, in case in place, M-framework 7140 can prevent that connector assembly 7506 from separating with second portion 7514.Should be noted that sub-audible sound generation unit 7504 can be mounted to M-framework 7140 and G-framework 7150 firmly.This hardness is installed can help to prevent hum, and amplifies sub-audible sound via back side of shell 7208, and wherein said back side of shell 7208 can be outstanding when personal media device 7100 is in the hard plane surface of desk or desk and so on.
Figure 77 shows the zoomed-in view of the part 7600 shown in Figure 76.Part 7600 provides the more detailed view about the joint of connector assembly 7506 and second portion 7514.More specifically, part 7600 shows the additional detail of the mesh heap of filtrator 7532.Filtrator 532 can be formed by ornamental mesh 7602, invades and deterioration second air path 7526 in order to other pollutants of anti-sealing and dust and so on.Between the erecting stage of personal media device 7100, connector assembly 7506 is mounted and is attached to PCB7508 by using the surface mounting technique that is called solder reflow or abbreviates backflow as.During reflow treatment, the scolder of fusion is used to each parts are electrically connected to electrical bonding pads and trace as a PCB7508 part.Because condition harshness (comprising high temperature), filtrator 7532 can not adhere to that therefore, filtrator 7532 can't be the integration section of connector assembly 7506 from the reflow treatment that is used for connector assembly 7506 is surface mounted to printed circuit board (PCB) 7508.Thus, filtrator 7532 can be installed after the mounting technology that uses " port-cullis " (that is sliding gate) by name is surface mounted to PCB7508 with connector assembly 7506.By using sliding gate, filtrator 7532 can use slit or groove and be dropped to appropriate position between erecting stage.In case in place, filtrator 7532 can use the bonding agent of glue and so on to come seal in place.In this way, filtrator 7532 can play sealing function to environmental pollutants, in order to avoid it enters personal media device inside.
Figure 78 shows along the viewgraph of cross-section 7700 of the line A-A of Figure 76.Viewgraph of cross-section 7700 shows the sealing ability of foam seal 7534 and the relation between adapter 7536 and the adapter 7538.More specifically, keep spring 7701 can be used for confining force F RetensionDirectly put on second portion 7514.Confining force F RetensionCan cause adapter 7536 directly closely to contact " lance " shape part 7702 of adapter 7538 again.In this way, the chamfering of lance shape part 7702 (chamfered) surface 7704 and 7706 can guide confining force F RetensionComponent (as foam power F FoamShown in), so that towards the part 7708 of M-framework 7150 " overcompression " foam seal 7534, significantly increase the sealing ability of foam seal 7534 thus.Sub-audible sound generation unit 7504 can comprise the alignment pin 7710 that size and shape conform to PCB opening 7712.Between the erecting stage of personal media device 7100, use the connector alignment pin 7714 that enters PCB opening 7716, connector assembly 7506 can be fixed to PCB7508.Sealing 7718 can be used to strengthen sealing, and reduces the possibility that sound is revealed thus.
