As mentioned above, front surface 3 is light-permeables, and as photoconduction.On viewing area 4, transmit light and provide light and the seamless photoconduction of the key icon 15 of throwing light on, reduced the quantity of the required illumination element of lighting apparatus, and provide the anterior zone of slave unit to another regional seamless transitions.By sending light with this technology and allowing the front surface of photoconduction 14 forming devices 1 as disclosed among the embodiment like that, equipment has visual impact, and 4 input areas 5 to push-button array 6 places do not have visible transition from the viewing area.

Embodiment shown in Fig. 1 has the light-permeable front surface 3 that can be made by sapphire or other precious stone.In case replace other more soft light transmissive material such as plastics with ore such as sapphire, will produce the other problem relevant with this properties of materials.For example when design front surface 3 is the durable equipment of friable material, many difficulties are arranged.In Fig. 1,2 and 4 to embodiment shown in 6 the form of expression, photoconduction 14 is selectable seamless composite beds.As can from Fig. 4, being clear that, can on the whole length of front surface 2, extend by polymethyl methacrylate or other is transparent and/or trnaslucent materials is made plastic layer 37.An otch 38 is arranged, be used to hold the preferred earphone speaker 18 that uses near ear.Also have another to hold the otch of light pipe scattering object 39.It is positioned at below the bolster 16 and the width of striding equipment 1 extends.By light pipe 39 being placed on below the bolster 16, avoided the bright areas on the front surface, the visible light in the light pipe will be scattered.LED40,41 each end at pipe 39 are positioned at each side of equipment.Be guided through pipe 39 and be scattered from LED40,41 light.Light pipe 39 in the present embodiment is coated with reflecting material, thereby the surface 42 of extending along LCD display 25 tops is passed in the light guiding.There is not the embodiment of coating that the some of them advantage is provided.Thereby the light of scattering is directed to wherein along the main shaft of photoconduction 14, so that the illumination uniformly basically for LCD25 to be provided.

By this way, light sucks the photoconduction 14 along main shaft from the LCD25 top.From the light illumination viewing area 4 of light pipe 39, and provide illumination to input area 5.As shown in Figure 15, be placed with other LED43 or other illumination element along the edge of perspex layer or sheet 37, be used for the icon 15 of the button of array 6 with further illumination at input area 5.The shaping surface of the extension 78 of perspex layer or sheet 37 will be for lighting the upper surface guiding of the light of LED67 etc. towards the main part of layer or sheet 37 from adjacent top.This helps to provide illumination uniformly basically to input area.Other LED43 etc. are covered by protecgulum 19 and can't see, and avoiding seeing luminous point, and promote to stride photoconduction scattered beam equably.

LCD25 self is bonded on the back side of perspex layer 37 by an energy absorption bonding sheet 45.Use this technology, and guarantee between LCD25 and polymethyl methacrylate sheet 37, do not have air gap, the scheme of a firm installation LCD25 is provided.Exquisite and surface apart from the LCD25 of the protective layer of its certain distance of needs is protected by the perspex layer 37 that is bonded on the one surface.The driver 44 that is used for LCD25 can be seen from Fig. 5.

In the embodiment shown, perspex layer 37 comprises hole 48, is used to locate each button, and allows 49 operations of button axle and contact with a printed circuit board (PCB) 50 that is arranged in shell 2, imports with recording user.For a more detailed description to the independent key arrangement that is suitable for using below in conjunction with the General Principle of being discussed.Because key arrangement is likely one of them durable component of design, having considered will need in future for shell and will design.Those skilled in the art will recognize that, can make amendment, the flexibility that adapts to following movement requirement still is provided simultaneously key layout.For example, as the input mechanism that is used for kneetop computer traditionally, available joystick or similar whirligig or multi-direction button are realized input.

As being clear that from Fig. 4, the second layer of compound photoconduction 51 is made of a plurality of part 52-58.This is in order to select to be used for the friable material of the second layer 51.Sapphire has the characteristic that comprises that scratch-resistant and light transmission wait well, is suitable for using herein, uses ceramic material in this set though the material of element also can be chosen in.Other suitable material is glass and other ore and valuable and semi-precious jewel.But when using precious materials such as sapphire, photoconduction provides the outer surface of equipment.When material is non-friable, needn't be similar in the embodiment shown conceptive and disclosedly like that the second layer be provided with.But it will be tangible that the replacement that for those skilled in the art, is used to hold friable material in this case is provided with.

As mentioned above, sapphire is frangible.When considering how to be used in this material in the lasting and durable shell 2 of needs, problem has produced.When equipment 1 will be clashed into inevitably, and when in its long-term existence process, repeatedly falling probably, especially can be this situation.All fragile parts all are bonded on the carrier of for example being made by plastics or titanium, with absorbing vibration better.In described embodiment, sapphire is formed among the each several part 52-58, to be easy to manufacturing.Each element is bonded on the perspex layer 37 with the ultraviolet cured glue on mixing acrylic acid technical foundation.For the durability that improves compound photoconduction 14 and strengthen its anti-damage capability, part 52-58 is bonded on the more flexible perspex layer 37, stay next gap 59 of on whole width, extending.These gaps 59 allow composite bed 14 to have relative flexibility along its main shaft as hinge.In the embodiment shown, considered this point during the layout of design push-button array 6.The whole width that alpha numeric keys 7 is striden second layer complex 51 divides the setting of three extension groups.Function button or soft-key button 8,9 are arranged in three two groups equally.Soft-key button 8,9 and top scroll button 12a follow the direction of the line of alpha numeric keys 7.Call treatment button 10,11 and define the lower limb of one of them element 57 and the top edge of another element 56 in the ranks with bottom scroll button 12b that other separates.This makes that second row button 10,11, the 12b is unusual, still can avoid the problem in making element 52-58 process simultaneously.Shown specific keys array 6 has other characteristic and the advantage of discussing below.

Although described embodiment considers to use friable material such as sapphire when design, the layout that produces can be made by any amount of other material such as plastics that required optical characteristics can be provided.Similarly, under the situation that does not break away from disclosed each inventive concept, can use different button settings.

Using under the situation of friable material as front surface optical conductor 14, when being connected with the remainder of casing member, front surface 3 run into problem equally.In the embodiment shown, the edge of breakable element 52-58 is by protecgulum 19 protections around whole surface alignment.In the present embodiment, protecgulum 19 is made of preceding cover support 60, and this preceding cover support 60 is covered by the sheet metal-preceding housing 61 of one 0.5 millimeters thick.These sheet metal 61 usefulness binding agents such as two parts epoxy adhesive or two parts acroleic acid binding agent are bonded on the preceding cover support 60 that can be made of plastics.Because sheet metal 61 is thinner relatively, can keep housing 2 weight to descend like this, cost that can also be relatively low uses valuable relatively metal such as titanium or gold.But protecgulum 19 can be a single part, and/or is made by homogenous material such as titanium.

Transparent surface 3 in this specific embodiment remains to the appropriate location securely by a reinforcing mechanisms.The perspex layer 37 that element 52-58 is bonded on it extends on the zone that is covered by these elements, thereby provides a lip or edge 62 around synthetic optical conductor 14.This edge 62 is used for front surface 3 fastening putting in place, because it contracts below the protecgulum 19 that defines the front surface periphery, and is squeezed between protecgulum 19 and the body side frame 20.

As seeing from Fig. 1, protecgulum 19 is strengthened by front surface protector 63, and the function of front surface protector 63 will be described in greater detail below.These front surface protectors 63 play the effect that casing member is kept together in this particular example.

Front surface protector 63 has the end portion 64 of an extend past protecgulum 19 and one and passes protecgulum 19 and enter axle 65 in the plastic side framework 20.Axle 65 can be fastened on the framework 20 with a nut 95.In this case, nut prevents to drop out in the front surface protector slave unit.In one embodiment, axle 65 at one end is threaded in terminal 64, is threaded in the side frame members 20 at the other end, though also can use other connected mode.Axle 65 and terminal 64 can also be one rather than two.As seeing from Fig. 9 b, the perspex layer 37 of protecgulum 19 and transparent surface 2 is by front surface protector 63 and side frame members 20 clampings.Thereby front surface protector 63 is clamped in transparent surface 3 between body side frame 20 and the protecgulum 19 securely.Front surface protector 63 only is close to push-button array 6 location.For around its peripheral fastening transparent surface 3, increased additional bolts 66, be used for protecgulum 19 is pulled to body side frame 20, and transparent surface 3 extruding are put in place.In one embodiment, bolt 66 was twisted body side frame 20 and was screwed in the preceding cover support 60.After preceding cover support 60 was fastened on the body side frame 20, the shell 61 of protecgulum 19 can be bonded on the supporting member 60, to cover the bolt end 66 that is screwed into.Replacedly, protecgulum 19 at first adheres on the supporting member (subassembly), then this subassembly is screwed on the framework.

As can seeing from accompanying drawing, although more flexible transparent base 37 is by covering by front surface protector 63 and the fastening protecgulum that puts in place 19 of other connector, sapphire keeps at interval with protecgulum 19, thereby to prevent it owing to contact cracked or be subjected to other damage.The edge of sapphire element does not reach protecgulum 19 tops, thereby further protects more frangible edge.In described the setting, transparent surface 3 is clamped on the position between protecgulum 19 and the body side frame 20.But more flexible matrix 37 can receive bolt or other securing member, thereby with respect to other frame element it is positioned, and can not damage more frangible sapphire layer.Selection for preceding cover material is open selection.Wherein precious metal comprises that gold, platinum, silver, steel are fit to.For the material of front protector, situation also is like this.These elements and those skilled in the art think that other suitable element can coat especially diamond of valuable or semi-precious jewel such as sapphire, ruby.Can also use other crystal or mineral, or other material and facing.

In order to reduce the intrusion of dirt or fluid, sealant 69 is placed between protecgulum 19 and the transparent surface 3.One of them mode that can introduce it is the bottom side that sealant is sprayed on protecgulum 19, when drying, is crushed between protecgulum 19 and the body side frame 20 in that protecgulum 19 and body side frame 20 are pulled in a time-out sealant.

As can from Fig. 6 or 9, seeing, in one first interface of guide rail 22 between side frame members 20 and front surface 3.Interruption between guide rail 22 curtain-shaped cover members makes it can't see, and protects the durability of frangible edge with enhancing equipment 1.Guide rail 22 can be the stamped metal spare around ' T ' tee section of the periphery extension of body side frame 20.When side frame members 20 and protecgulum 19 are pulled in a time-out in assembling, ' T ' trunk 68 is clipped between these two elements.The T trunk has and is positioned at the aperture 70 on the corresponding projection 71 on the body side frame 20, is extracted out between two parts when preventing on the throne putting.The T top is as loading plate, and additional extrusion 72 soldered or otherwise be bonded on it are to provide seamless final products.Trunk also can be made by plastic material.

Side frame members 20 in this specific embodiment is the plastic supporting spares 73 that enclosing cover 74 is arranged.Lid 74 can be a sheet metal of for example being made by precious metal equally, perhaps perhaps is panelling or another leather or other extexine.The most suitablely layer is bonded to material that the binding agent on the plastic frame element 73 bonds as required and different.For metal bonding to plastics, the binding agent that is fit to be two part epoxies or, two part propylene acid binders.To metal, binding agent can be active polyurethane film or two parts epoxy resin for metal bonding.Similarly, the bonnet 21 in the present embodiment can have plastic frame, and covers with for example leather, timber or metal finish.For flexible finishing material such as leather, preferably material is strained on framework.This is by realizing with routine techniques in lamination process.

Transparent surface 3 provides a seamless transitions between display 4 and input area 5.In viewing area 4, LCD25 is arranged in transparent surface 3 back input areas 5, and press button mechanism 75 is positioned at its back.In a described embodiment, can see that press button mechanism 75 passes front surface 3.But in other embodiments, the inner surface 76 of polymethyl methacrylate matrix 37 can apply opaque material, and is in sight to prevent device interior.For those skilled in the art, prevent that otherwise the descried replacement method of equipment inner structure from being clearly, as introduce additional opaque layer or otherwise obstruct the view.

Embodiment for for example seeing button operation mechanism 75 by front surface 3 may need to prevent that PCB50 is in sight.

The housing 2 of being constructed provides a shell that is used for printed circuit board (PCB) 50 and a battery 79 that keeps core part 24.When equipment 1 is radio telephone, is provided with a SIM card keeper 80 and holds SIM card 81.For the operation of carrying out under some wireless protocols, clearly this will be unnecessary.

Temporarily get back to the equipment front portion, what be positioned at 4 tops, viewing area is a bolster 16, and name is because it is designed to be used in above the family leans against his or her ear when carrying out call like this.The earphone 18 of bolster 16 overlay devices.As previously mentioned, an otch is arranged in the polymethyl methacrylate matrix 37 of optical conductor 14, be used to hold earphone 18, the bolster 16 in the illustrated embodiment is bonded on the polymethyl methacrylate matrix 37 that covers earphone 18.Bolster 16 provides the suitable aperture 17 of sound guidance to the user.The feature of bolster 16 on material and incrustation can be by the side's of commissioning selection.

Polymethyl methacrylate and sapphire optical conductor 14 are relative colder for touching, and the material of bolster 16 may be selected to be for touching heat relatively and more being not easy to the material of mark than transparent glittering surface.Being considered to particularly suitable material is pottery or timber and leather facing.The shape of bolster 16 has been covered partial L CD25, and the relative gable 82,83 that is used for showing battery meter respectively with signal strength signal intensity is provided.

For finishing structure, housing 2 has a bonnet 21 and is suitable for keeping the internal chamber 84,85 of the SIM card 81 in movement and battery 79 and the present embodiment.Identical with many other radio telephones, apparatus shown advantageously allows to reach battery chamber 85, because battery 79 needs periodic replacement.For protection movement 24 in this active procedure, battery 79 is remained in the chamber that is connected that provides with movement 24.With battery chamber 85 in the present embodiment side by side be SIM card retainer 80.Be used to preserve under the agreement of ordering information in SIM card 81, the user can expect to take out SIM card 81.For this reason, take out bonnet 21 and expose battery 79 and SIM card 81 is easily.Battery chamber 85 and SIM card retainer 80 are provided by an inner housing element 87 that is fastened on the body side frame 20.It can be made by plastics or one or more other suitable material, and in one embodiment, chamber is made by stainless punched metal sheet.

Battery contact 90 is projected in the battery chamber 85, thereby a plain mode that battery 79 is connected with movement 24 is provided.Battery connect generally have a power connector 91, earthing conductor 92 and two signal connectors 93,94.

In the embodiment shown, power supply 91a, b, c and earthing conductor 92a, b, c connector are divided into three.This has reduced the resistance between battery 79 and the movement 24, because lead is in parallel, this has also reduced to make the chance of energy loss in the movement 24 owing to having reached the harmonic resonance frequency, because in institute free in, at least a portion in per three parts connectors is all connected the circuit between movement 24 and the battery 79 probably.

Housing 2 is finished by bonnet 21 is assembled on the body side frame 20.In the embodiment shown, bonnet 21 is made of three elements 96,97,98.First element, 96 cover antenna positions.In this embodiment, it provides an aperture 99, and multitone loud speaker 27 is arranged in this aperture 99, so that the multitone sound to be provided.This extension speaker 27 does not have the loud speaker 18 of image position below bolster 16 to optimize like that to be used for using near ear.This more effectively uses it as non-hand-held loud speaker, and can use wider around tonequality.Because first element, 96 same cover antenna, its dielectric constant is proportional.

Can be in counting this equipment one by one at housing 2 for movement 24, its manufactured materials is very important.They should be wear-resistant and lasting, keep their characteristic in than required longer time at present.For this reason, for some embodiment of the present invention, consider with a kind of selection of pottery as bonnet 21.Other material of having discussed as metal or precious metal or facing, also is fine.But for pottery, although have many required features, for the close position of device-dependent antenna that holds this element, the dielectric constant of material disturbs mutually with required conduction mode.

In order not make the many required feature that they are provided under the too high situation of dielectric constant, the material that available dielectric constant is lower is made back cap member 96 and is deposited the coating of appropriate depth thereon.This technology and the material of being advised can be used for other element of housing.

The back casing element 96 that covers antenna is threaded onto on the side frame members 20 equally, and second guide rail 23 in this process that structure is similar to first guide rail 22 is clamped between body side frame 20 and the bonnet 21.Equally, guide rail 23 is provided with and is positioned at the aperture 70 on the corresponding projection 71 on the body side frame 20, thereby more firmly guide rail 23 is kept putting in place when connecting bonnet 21.

One second back casing element 97 covers battery chamber 85 and SIM card retainer 80.This element releasably is fastened on other casing member with bolt 99, thereby can be relatively easily near S IM card 81 and battery 79.In a preferred embodiment, bolt 100 rotates 1/4th commentaries on classics can unclamp cap member 97, thereby can take out it.Same action can disconnect battery 79, thereby can take out SIM card 81.

The second back casing element 97 with to described similar mode at the first back casing element and be connected on the body side frame 20.

The three element of back casing 98 covers non-hand-held loud speaker 27.It can only be thinner relatively, and is made by precious metal such as gold.To a suitable aperture 102 be set, be used for sound from can guiding at the multitone loud speaker 27 that non-hand-held mode is used, and provide one can hear around tonequality.

In described embodiment, front surface 3 and back casing element 96,97,98 are fastened on the body side frame 20.Can extrude silicone encapsulant 69 or analog around bonnet 21 inboards, invade undesirably to prevent dirt or fluid.

Those skilled in the art will recognize that, under the situation that does not break away from described some inventive concepts, can change the quantity of parts and their connected mode.For example in other embodiments, available other technology or otherwise housing is kept together.

Except covering exposed edge, guide rail 22,23 also provides other element that is used to customize, because they can be made by multiple different materials, the dissimilar precious metal of discussing at protecgulum as the front particularly is as gold or platinum.The material that is used for whole ' T ' shape part or extrusion element can be a precious metal.But they also the brittle edges of boundary belt facing framework in order to avoid be exposed to potential damageability.In this process, the crested of unhandsome edge be can't see.This provides and corresponding to quality of the global concept of the kept housing that is used for communication equipment and persistence.Do not consider finishing material, this is to be used for that fastening the putting in place of whole elements obtained the convenient of durable finished product to be provided with.

In the alternative embodiment shown in Fig. 4 b, do not provide the edge that guide rail 22,23 is protected exposure, but with the inside rotation of neighboring edge 105,106 self, and keep near.This set also provides the advantage of protection and unhandsome interruption be can't see.

Housing with front surface of light-permeable provides new chance.In a particular embodiment, with reference to Figure 12 and 14 described, the icon 15 relevant with the button of push-button array 6 is positioned on front and rear surfaces 37a, the 37b of perspex layer 37.Become increasingly complex along with communication equipment becomes, it is very normal that each button has a plurality of different functions.Can be useful for the different possibility functions relevant with button are labelled with seeing.Especially for alpha numeric keys 7, each button and a single numeral and one group of letter or symbol are relevant.Ideally, these show with should be understood that.

Keeping relevant icon on the button traditionally.But because equipment is more and more littler, there is a special difficult problem in this difficulty more that becomes being used for distinguishing between the different icons of various operator schemes, because letter and number is so little.In the embodiment shown, the icon 15 that is used for related key is positioned at each surface of optical conductor 14, and when equipment was swung, icon 15 moved together or is moved apart with their observed angles are different.This provides in the visual differentiation between the icon on the different surfaces 15, is used between the different operation modes and distinguishes.Because front surface can printing opacity, icon can float in equipment or on the equipment.Perpendicular to the 3rd size, the axis of the thickness direction of front surface is spaced apart with icon, has provided some projections to front surface, thereby has increased added size to common opaque front surface by the edge.

In the embodiment shown, icon 15 is positioned on the outermost or inner surface of perspex layer 37a, 37b.Icon 15 can float in light-transmittable layer.The mode that icon 15 is positioned on the layer is those skilled in the art's a selection problem.One of them method is with the etched plate that is filled with ink icon to be printed onto on the surface.Another kind of mode is with PVD (physical vapor deposition) technology ' stamp ' directly to be deposited on the perspex layer.Can also use the technology of other anchor icon, comprise adhesive label.

In the embodiment that is discussed, icon 15a, 15b are positioned on the apparent surface of perspex layer 37a, 37b.Can print single element like this, perspex layer 37, rather than each of sapphire or other element 52-58.By the surface that holds stamp with second layer protection, the problem that the consumption of ink of also having avoided running into when the use printing technology falls.In other embodiments, for the degree of depth that improves the icon spacing and when when different angles are observed, strengthening possible separation, may need icon is placed on the outermost layer and innermost surface 37a, 51a of synthetic.For the icon 15 of fixing printing on the outer surface 51a that meeting is worn, can provide a coating or other protective layer from the teeth outwards.If form icon 15 then this is unwanted with the PVD technology, because this technology has produced bonding at sedimentary deposit and between the matrix that more is difficult to wear and tear.In another embodiment, can on the innermost layer of the bottom side of sapphire element 51b and polymethyl methacrylate matrix 37a, icon 15 be set.Equally, the problem of the outer surface by avoiding hyaline layer has greatly been avoided the wear problem of icon 15.The outermost layer icon can not be near innermost layer icon 15 by top layer 51 protections of synthetic optical conductor 14.

In the process that icon is clipped between two light- transmittable layers 37,51, which the carrying icon in two double team layers is very inessential.Which if the character of various materials is different really, then when decision layer 37b, 51b actual bearer icon, the character and the other factors of these materials can be taken into account.For compound light-permeable matrix, the layer that provides is many more, but the vision component-bar chart that then can hold mark is many more.For example,, three planes that can be used for icon are arranged,, four planes are arranged for three layers for two composite beds, or the like.If all icon is all placed in abutting connection with a single button, then vision is distinguished the difficulty that can cause distinguishing with a large amount of layers function.Other embodiment can be on equipment diverse location use different planes, thereby one group of button has an icon on first plane, have second group of button in second plane, or the like.

In order to strengthen the phantom that icon floats, perhaps improve the differentiation between two-layer, can improve the thickness of selecting light-transmittable layer that has between each layer of carrying icon.In an identical manner, can reduce these features by the thickness between the plane that reduces to carry icon.

Can select ink or paint by those skilled in the art, so that multiple effect to be provided.Ink for example may need pearly-lustre or fluorescence, one or more in perhaps black, the white or wide range colors.Because icon is positioned on the photoconduction, fluorescence or pearlescent material have strengthened the visuality of icon.Typewriting person's handwriting, color or other character of the element of icon or carrying icon can be by the side's of commissioning selections.

Except to the technology of surperficial ink filling or other visual material, if illumination is talked about fully, only these layers being carried out etching may be enough to make icon visual.

The embodiment of the expression picture mark position relevant with button in the light-permeable surface has been described with reference to embodiment shown in the content of other independent invention feature of requiring in co-pending application.Those skilled in the art will recognize that, without departing from the present invention, can carry out multiple replacement disclosed special characteristic.

Those skilled in the art will recognize that, can carry out comprehensive or coupling to the described feature of top particular element, to adapt to multiple different design alternative at equipment.

Main now for a more detailed description with reference to the input area of Fig. 9 and 15 to 21 pairs of equipment.

As mentioned above, input area 5 comprises a push-button array 6.In this embodiment, push-button array is made of a plurality of independent button 7-13.In these independent buttons each comprises a button terminal 64 and the axle 49 that stretches out from the center of button end 64 basically, and begins respectively along a upper bearing (metal) 103 of 49a location, O shape circle 107, little ring 108, latch plate 110 and lower bearing 109 from button end 64.Latch plate 110 is by a latch plate supporting member 114 supportings that are arranged on the PCB118.Latch plate comprises a main body and a tongue 111 of being made by the single piece of metal sheet.This tongue is made by the inside of punched metal sheet, makes the both sides of tongue and all the other main bodys that an end does not have sheet metal.Latch plate also has one or more parts that stamp out, with the hole that provides to be used for the latch plate supporting member 114 of button axle 49.One end 113 of latch plate comprises the contact that contacts with each contact region on the PCB.As the skilled person will appreciate, an available single contact is used for this purpose, provides bigger reliability but two contacts are set.Latch plate supporting member 114 comprises three from the upright element of PCB118.These elements can constitute an integrally-built part, perhaps can be discrete elements.First element comprises a groove 115, and it is sized to receive an end 112 of latch plate 110, and end 112 is kept putting in place.Second element of supporting member 114 comprises a lip 116 that extends towards first element.This lip 116 is arranged for the moving upward of the other end 113 of restraining spring plate 110.The three element of supporting member 114 comprises a groove 117 that is used to receive the end of tongue.This three element is located with respect to second element, makes the bending of having to of the tongue of latch plate 110, makes the end of tongue corresponding to its groove 117.Selectively, the latch plate supporting member can comprise a quaternary part, and this quaternary part comprises a lip that extends towards second element.In this case, the PCB contact region extends to the surface of this lip, thereby makes their more close latch plate contacts.Replacedly, the contact region of carrying lip can form the part of second element self, perhaps all saves.

As mentioned above, in the present embodiment, each button is divided into three groups, and their end extends across the whole length of the second layer of complex 51.This helps the manufacturing of breakable element 52 to 58.The end of other button in the end of alpha numeric keys 7, soft-key button 8,9 and top scroll button 12a and their group is aimed at.But in the button of all the other groups, the end of bottom scroll button 12b two buttons in addition from its group, promptly the terminal straight line of call treatment button 10,11 is removed.Under any circumstance, in each group, the edge of adjacent key end is all complimentary to one another, and low coverage is liftoff spaced apart.This makes complex 51 or other packing material need not extend between the button end.It also has such advantage, has promptly simplified the overall appearance of the input area of equipment for the user.Other character and the advantage of specific keys array 6 are discussed below.

As seeing that from Figure 17 and 18 latch plate 110 of adjacent letters digital keys 7 and supporting member 114 are located with being perpendicular to one another especially.This can not aim at this problem of button self poisoning for latch plate and provide a simple solution on how much.The latch plate that this problem reason is each external key in the illustrated embodiment is longer than its average length corresponding to the button end, and this unnecessary length can not be held in other position.This mainly be because the latch plate of each center button only minimally is less than the average length of corresponding button end, and these buttons are closely in abutting connection with (only having about 0.245 mm clearance) between button, thereby insufficient space is to hold this unnecessary length.In addition, although the button axle 49 of each button basically at the center of button end 64, the button axis hole of latch plate 110 is eccentric.This has aggravated the problem for external key, even causes the latch plate of each center button can not be contained in the space below its corresponding button end.

Button can as described belowly be constructed, and the input area of equipment can as described belowly be assembled.Upper bearing (metal) inserts in the hole 48 of equipment perspex layer.Owing to three reasons, preferably select the ruby bearing to be used for this purpose.At first, ruby is very difficult to wearing and tearing, thereby can handle a plurality of button operations in considerable time.The second, the upper bearing (metal) of equipment greater than the corresponding width of button end, this means that under the transparent situation of equipment front surface they can be seen (can be sapphire as the second layer 51) on diameter.Therefore, can utilize such advantage, promptly ruby is attractive jewelry, and the user can be very glad and see it.The 3rd, elastomeric material such as PFTE are opposite with using, and hard material such as ruby use will make key groups install to have bigger accuracy in the equipment.

Lower bearing 109 is arranged in the titanium plate that is fixed to the PCB118 rear portion.The inner and outer diameter of lower bearing 109 is less than upper bearing (metal) 103, but their centrally aligned.They also preferably by different materials-have the lower bearing material of shock-absorbing character, are made as PFTE.

Button axle 49 is processed into has a 49a of first, and the 49a of this first has suitable thickness, passing the internal diameter of upper bearing (metal) 103, and one second part 49 that diameter reduces, to pass the internal diameter of lower bearing 109.Axle 49 and little ring 108 can be processed by a single piece of metal, perhaps little ring 108 can be connected to subsequently on the axle 49.They are preferably made by stainless steel.In addition, near little ring 108 axle 49 than major diameter part 49a on be provided with O shape circle 107, so that water-stop to be provided.The external diameter of little ring 108 and O shape circle is all less than the external diameter of upper bearing (metal), thereby the user can not see them when in the original place.But the external diameter of little ring is more abundant greatly than the internal diameter of upper bearing (metal), thereby prevents to drop out in the button slave unit.

The button end can be metals like gold, platinum, silver or stainless steel by material requested, is made into required form.They can also have precious stone.For example, one or more button ends can wrap with the diamond shell, perhaps have precious stone therein.In case the button axle passes after the upper bearing (metal), the button end joins on it.The hot steaming technique of this available routine is finished.

Latch plate supporting member 114 is arranged on the PCB118.Each latch plate supporting member 114 preferably has integrative-structure, is made by lightweight metal such as aluminium.Available then routine techniques with the supporting member soldered to PCB.Latch plate supporting member 114 is positioned to keep latch plate 110, makes their center of axis hole and the centrally aligned of lower bearing 109.The contact region that is used for the latch plate contact is arranged on PCB (perhaps as mentioned above second of supporting member or the lip of quaternary part).

Latch plate 110 self is made by punched metal sheet, as has the copper beryllium alloy or the analog of golden light.Through the following steps plate 110 is fixed on the supporting member 114: an end 113 of latch plate is positioned at below the lip 116 of second element of supporting member 114, the other end 112 of latch plate is installed in the groove 115 of first element of supporting member 114, crooked tongue makes the three-element groove 117 of its end corresponding to supporting member 114, and the end of tongue is positioned in this groove.When in position going up, the free end 113 of latch plate 110 is naturally upwards towards restriction lip 116 bias voltages.

The size of button each several part and their relative position are very important in the button quiet run.By they being placed the both sides of latch plate fixture and axle is passed latch plate, and make the distance between the metal (upper maximum.In such position, bearing keeps straight line with it when button is operated, thereby avoids contacting with adjacent key is terminal, does not perhaps need to be placed to button separately further and to prevent contact.Cause good switching function and sensation so again.

In addition, the size of button is like this, make that unnecessary pressure is applied on the latch plate 110 before, the lower surface of each button end 64 contacts with the surface of perspex layer 37.In the present embodiment, little ring 108 is along the axle location, thereby when button was in normally not pressured state, it placed on the latch plate slightly.In addition, when being in normal condition, the thicker part branch of axle has suitable length, between the surface of the lower surface of button end and perspex layer 37 gap is arranged, this gap with in order to make the contact contact region little ring 108 necessary distances of moving in latch plate contact identical or bigger.Pressure is applied to the problem on the latch plate if this has overcome that switch self provides the end stop of motion.

The size of button is for the outward appearance no less important of equipment.Preferably, the thickness of button end equals at least when button is in above-mentioned normal condition from the outstanding distance in surface of the second layer 51 of complex.When the complex substantial transparent, will provide the impression of the button that floats like this, and increase the front about key icon 15 described 3-D effect early.In addition, the button end should be enough dark, thereby part sinks in the second layer of complex, and preferably have at least two relative flat basically sidepieces corresponding to the sidepiece of the second layer, to prevent the horizontal rotation of button.In this equipment, between the second layer of button and complex, realized the gap of one 0.1 millimeter magnitude: very small for human eye and be suitable for preventing the horizontal rotation of a button gap.In the present embodiment, tilt, further stoped horizontal rotation by the mirror image that the adjacent key sidepiece is provided.

In order to ensure the correct relative spacing of Key element, perspex layer 37, PCB118 and titanium plate 77 are clamped together.In the present embodiment, clamping is by front surface protector 63, and additional cone boss realizes by being provided with on the projection 68 of poly (methyl methacrylate) plate and associated anchor.Therefore, in case behind the button location, just can perspex layer, PCB and titanium plate holder be held in together with boss and fixture, thus button is kept putting in place and forming a controllable module.This module then can be with being installed in the equipment at an easy rate as the top front surface protector of describing with reference to Fig. 9 B.

Operation to device keys now is described.Because the user exerts pressure to the button end, this axially moves down, and the axis hole of bearing and latch plate is passed in operation.This a part of main body that causes little hoop to define the latch plate of axis hole is exerted pressure.Continue after the button end is exerted pressure, to cause this partial spring plate of little hoop to apply the pressure of increase, cause main ring around little annular strain.Finally, this distortion will cause tongue off-centre, and the free end 113 that makes latch plate 110 is from its natural biased position (upwards towards restriction lip 116) tip-tap to a second place, and wherein the latch plate contact contacts with contact region on the PCB.Send the signal of telecommunication of an expression key actuation subsequently to processor.This set has provided a different click, clearly illustrates that to the user button activates.When the user removed pressure from button is terminal, little ring was removed pressure from latch plate 110 again.This tongue returns its normal position immediately, and the free end of latch plate makes progress tip-tap to its natural biased position, disconnects contact.

Figure 20 a is a chart, the power of button of expression as shown in Figure 17 and 18 adjust the distance by line.This curve has improved button in for example sense of touch of common key-press dome structure, as seeing from Figure 20 b that it has quite flat curve.When using conventional button dome structure, the user must apply a constant power, up to the point of key actuation.As a result, he does not obtain a tactile cues when activating when will take place him near this position.On the contrary, when with the equipment shown in Figure 17 and 18, owing to must improve for given stroke applied force of button, the user can recognize this fact, promptly when actuating will take place he near this position.In addition, when activating generation, and when stopping to activate, the user is apprised of by the click sound that is provided by button.

The center V-arrangement button end of embodiment shown in Fig. 1 makes the user can determine the central vertical axis of equipment by visual and touch.A summit is set on bolster 16 to be made it to be more prone to.Therefore, the user can locate required center button apace.The summit of each center button is also identified along the mid point of button tip length, and button axle 48 begins to extend from this point.Therefore, they help pressing keys more accurately.This helps again to prevent to contact with adjacent key is terminal, does not perhaps need button is arranged to prevent this contact further the branch.

Similarly, in this embodiment, being used in combination the family and can determining the position of vertical axis of the terminal front surface protector with the formation V-arrangement of adjacent external button with respect to a side at external key place.Therefore, the user can locate required external key fast.In the present embodiment,, help key position to handle because external key extends to the second layer of complex 51 and the interface between the protecgulum 19.

The front surface of equipment shown in Fig. 1 is by bolster and 63 protections of front surface protector.Front surface 3 is microprotrusion slightly, and peak is along its central longitudinal axis location.Therefore, usually, face down if be placed to, then equipment will place on this axis, cause its surface scraping.Clearly, this is unacceptable, particularly when second layer complex is sapphire or analog.Device design shown in Fig. 1 becomes to be used to prevent this problem.Bolster 16 and surface protection device 63a prevent that equipment from placing on the second layer complex.In addition, as mentioned above, in a preferred embodiment, the button end is outstanding slightly from the surface.Therefore, button end in center can protect second layer complex to avoid damaging equally.But preferably, bolster 16 and bottom front surface protector 63a are risen to enough height of front surface top, equipment is not interposing on the button end of center, thereby protects them to avoid damaging equally.

Knocked if equipment also is designed to marginal surface, can be protected front surface.As can seeing that protecgulum front surface protector 63b is projected into outside the surface of second layer complex along the interface with protecgulum from the front view of equipment as shown in Figure 21, thereby protection second layer complex is avoided damaging in this zone.They have also reduced protecgulum owing to knocking the possibility of damaging.In addition, they are also outstanding further than adjacent key end, thereby protect these button ends to avoid damaging equally.

Another benefit of front surface protector 63, particularly protecgulum is, is placed to and faces down if they are sized to equipment, can prevent that button from unexpectedly activating.That is to say; the end face of front surface protector end should and the end face of button end in sustained height or higher (as the relation between protector 63b and the adjacent external button end); if perhaps they are positioned at one than the lower height of the terminal end face of button, then the protector end face must be less than activate the distance that button need button to move for the latch plate contact is contacted with the LCB contact region with the distance between the button end.

Figure 22 to 25 illustrates the another kind of button and/or the front surface protector structure of equipment among Fig. 1.

Figure 22 illustrates another kind of key arrangement, utilizes the inventive concept of button as touch-sensitive display equally.The shape of button is similar to the shape of the alpha numeric keys array of equipment shown in Fig. 1, has not together: the longitudinal axis of the side in alignment equipment of button.
