In the headphone 1 according to the embodiment of the present invention, the headband unit 12 includes at least one side pressure supplying member. In the example shown in the drawing, the headband unit 12, which has both end parts supporting a pair of sound emitting parts 10, 10, includes a first side pressure supplying member 13, a second side pressure supplying member 14 and a positioning band 15. The first and the second side pressure supplying members 13, 14 are elastic members including curved shape, which are formed along the positioning band 15 and supply a side pressure pressing a pair of sound emitting parts 10, 10 to a counterpart attachment position. With the positioning band 15 placed on the head of a user, the sound emitting parts 10, 10 are positioned with respect to the ears of the user.
Both end parts of the headband unit 12 (the first and the second side pressure supplying members 13, 14 and the positioning band 15) are connected with a pair of the supporting arm parts 11, 11 via the connecting parts 16. In the example shown in the drawing, the positioning band 15 and the second side pressure supplying member14 are attached to the connecting part 16. In the first side pressure supplying member 13, the end part 13A of the first side pressure supplying member 13 is attached to the connecting part 16. The end part 13A of the first side pressure supplying member 13 is removably attached to the connecting part 16.
The connecting part 16 of the headphone 1 is described in detail with reference to Figs. 2 to 4. Fig. 2 is a view illustrating the connecting part 16 of the headphone 1. Fig. 2(a) is an external view and Fig. 2(b) is a view illustrating the inside of the headphone. Fig. 3 is a view illustrating the removable part 20 in the connecting part 16 of the headphone 1. Fig. 4 is an exploded view of the removable part 20 in the connecting part 16.
In the example shown in the drawing, the end part 15A of the positioning band 15 is attached to the second side pressure supplying member 14 via an attaching member 17 configured with a screw 17A, an attachment pat 17B and a counter attachment pat 17C. The attaching member 17 is attached to the second side pressure supplying member 14 such that the position of the positioning band can be changed with respect to the second side pressure supplying member 14. More specifically, the second side pressure supplying member 14 passes through the hole part of the attaching member 17. Further, the attaching member 17 is arranged at a prescribed position along the second side pressure supplying member 14. Thereby, with the attaching member 17 arranged at the prescribed position of the second side pressure supplying member 14, the positioning headband 15 can be arranged in accordance with user preferences. A plurality of protruding parts 14A are provided spaced-apart a predetermined interval on a face of the second side pressure supplying member 14, defining the positions of the attaching member 17(see Fig. 5). The attaching member 17 is arranged at the position in relation to this protruding part 14A and the positioning band 15 is positioned so as to correspond with the ears of a user.
Further, the end part of the second side pressure supplying member 14 is attached to the connecting part 16, and the second side pressure supplying member 14 is fixed to the connecting part 16. In response to a change in position of the positioning headband 15 with respect to the second side pressure supplying member 14, a position of the pair of the sound emitting parts 10 is changed with respect to the ears of a user. Further, a side pressure to the ears of a user may be changed at the same time.
The connecting part 16 includes an inserting hole part 16B into which the end part 13A of the first side pressure supplying member 13 is inserted. Further, the connecting part 16 includes a tubular shape part 16C configuring the inserting hole part 16B. The tubular shape part 16C has a face opposing the end part 13A of the first side pressure supplying member 13. With the end part 13A of the first side pressure supplying member 13 inserted into the inserting hole part16B of the connecting part 16, the end part 13A is removably fixed to the connecting part 16. When the end part 13A of the first side pressure supplying member 13 is attached to the connecting part 16, the end part 13A may have contact with the face of the tubular shape part 16C.
The connecting part 16 includes a removable part 20, which allows the side pressure supplying member to be inserted into or removed from the connecting part 16. In the example shown in the drawing, the connecting part 16 is provided with the removable part 20, which allows the end part 13A of the first side pressure supplying member 13 to be inserted into or removed from the connecting part 16 when a cover 16F of the connecting part 16 is removed. The removable part 20 includes an engaging member 21 and a releasing member 22. The engaging member 21 is engaged with a part of the first side pressure supplying member 13 that is connected with the connecting part 16 and a releasing member 22 releases the engagement between the engaging member 21 and the part of the first side pressure supplying member 13.
The releasing member 22 is provided displaceable against the connecting part 16. Also, a part of the engaging member 21 is attached to one end part of the releasing member 22. And, the engaging member 21 and the first side pressure supplying member 13 are spaced apart each other due to the displacement of the releasing member 22 against the connecting part16. More specifically, the releasing member 22 is displaced against the connecting part 16, thereby the engaging member 21 is elastically deformed and is moved away from the end part 13A of the first side pressure supplying member 13 in response to this elastic deformation of the engaging member 21, and thus the engagement between the engaging member 21 and the end part 13A of the first side pressure supplying member 13 is released.
Hereinafter, the removable part 20 is described in more detail. As shown in Fig. 4, the engaging member 21 includes a first part 21A fixed to the inside of the connecting part 16, and a second part 21B that is displaced against the first part 21A around the end part 13A of the first side pressure supplying member13, which is inserted into the inside of the connecting part 16. More specifically, the engaging member 21 is configured with a plate-shaped elastic member and includes a bending part 21C between the first part 21A and the second part 21B along the axis direction of the end part 13A of the first side pressure supplying member13. The first part 21A and the second part 21B are substantially bent or folded at this bending part 21C such that the second part 21B is displaced against the first part 21A. The second part 21B is displaced in the axis direction of the releasing member 22.
As shown in the drawing, the first part 21A of the engaging member 21 includes an attaching hole 21E, and an attaching member (screw) 18 inserted into the attaching hole is attached to an attaching counterpart 16E of the connecting part 16 such that the first part 21A is fixed to the inside of the connecting part 16. On the other hand, the second part 21B of the engaging member 21 is attached to a first flange part 22A provided at the end part of the releasing member 22 by an attaching member 22E.
The second part 21B of the engaging member 21 includes an engaging part 21B1, which is engaged with an engaging counterpart 13A1, which is arranged inside the connecting part 16. A part of the first side pressure supplying member 13 has the engaging counterpart 13A1. The engaging counterpart 13A1 is provided at the end part 13A of the first side pressure supplying member 13.
The engaging counterpart (recessed part) 13A1 provided at the end part13A of the first side pressure supplying member 13 includes a recessed cross-sectional shape toward the inside of the end part 13A. In contrast, the engaging part 21B1 of the engaging member 21 includes a cross-sectional shape, which is folded from the second part 21B in the axis direction of the end part 13A of the first side pressure supplying member 13 to the axis direction of the releasing member 22.
The releasing member 22 includes one end part arranged inside the connecting part 16 and the other end part arranged outside the connecting part 16, and the one end part of the releasing member 22 is connected with the second part 21B of the engaging member 21. And, the releasing member 22 includes a first flange part 22A connected with the second part 21B of the engaging member 21, a second flange part 22B opposite the inner side face of the connecting part 16, and a release-operating part 22C arranged outside the connecting part 16. A release-operating part 22C passes through the inside of the hole part 16A of the connecting part 16 and projects to the outside. Further, the outer diameter of the second flange part 22B is larger than the inner diameter of the hole part 16A. Thereby, the second flange part 22B functions as retaining that allows the release-operating part 22C to project outside the connecting part 16 by a predetermined length.
The releasing member 22 includes a pole part 22D between the first flange part 22A and the second flange part 22B, and the pole part 22D has a face opposing the end part 13A of the first side pressure supplying member 13, which is provided on the side of the connecting part 16. When the end part 13A of the first side pressure supplying member 13 is inserted into the inserting hole part 16B of the connecting part 16, the tip of the end part 13A has contact with the face of the pole part 22D of the releasing member 22, thus the length of the end part 13A inserted into the connecting part 16 is defined. Further, as shown in Fig. 4, when the tip of the end part 13A has contact with the pole part 22D, the engaging part 21B1 of the engaging member 21 is engaged with the engaging counterpart 13A1 of the end part 13A. Further, when the end part 13A is attached to the connecting part 16, the end part 13A may have contact with the pole part 22D or a given interval may be provided between the end part 13A and the pole part 22D.
The end part 13A of the first side pressure supplying member 13 includes an inclined face 13A2. This inclined face 13A2 is configured such that the outer diameter of the end part 13A is decreased from the engaging counterpart 13A1 to the tip of the end part 13A. On the other hand, the second flange part 22B has an inclined face 22B1 opposite the inclined face 13A2 provided at the end part 13A of the first side pressure supplying member 13. This inclined face 22B1 is configured to have contact with the inclined face 13A2. For example, the inclined face 22B1 has a face along the inclined face 13A2.
The inside of the connecting part 16 has a space that allows the engaging member 21 and the releasing member 22 to be displaced. When the release-operating part 22C of the releasing member 22 is pressed, a part of the releasing member 22 is displaced in the space inside the connecting part 16. In response to the displacement of the part of the releasing member 22, the second part 21B of the engaging member 21 attached to the first flange part 22A of the releasing member 22 is displaced against the first part 21A. In response to the displacement of the second part 21B, the engagement between the engaging part 21B1 of the engaging member 21 and the engaging counterpart 13A1 provided at the end part 13A of the first side pressure supplying member 13 is released. Further, the engagement between the engaging part 21B1 and the engaging counterpart 13A1 is released, while the displacement of the releasing member 22 in the direction from the second flange part 22B to the first flange part 22A causes the end part 13A of the first side pressure supplying member 13 to be displaced in the direction from the inside to the outside of the connecting part 16. That is, the displacement of the releasing member 22 causes the inclined face 22B1 provided at the second flange part 22B of the releasing member 22 to have contact with the inclined face 13A2 provided at the end part 13A of the first side pressure supplying member 13, and the contact between the inclined face 22B1 and the inclined face 13A2 and the displacement of the releasing member 22 causes the end part 13A of the first side pressure supplying member 13 to be pushed toward the outside of the connecting part 16.
The headphone 1 may have a plurality of different first side pressure supplying members 13. As plurality of the first side pressure supplying members 13, for example, the cross-sectional shape for one of the first side pressure supplying members 13 may have an outer diameter larger than that for another one of the first side pressure supplying members 13. In this example, the outer shapes (curving diameters) of the first side pressure supplying members 13 may be substantially equal to each other, or the outer shapes (curving diameters) of the plurality of the first side pressure supplying members 13 may be changed to be different from each other. With the cross-sectional shapes or the outer shapes of the first side pressure supplying members configured to be different each other, the bending rigidities of the first side pressure supplying members 13 are different each other, thereby the side pressures of the plurality of the first side pressure supplying members 13 can be altered. Further, as described above, the positions of a pair of the sound emitting parts 10 with respect to the ears of a user is changed in accordance with the position change of the positioning headband with respect to the second side pressure supplying member 14. In this case, a side pressure can be adjusted by attaching the first side pressure supplying member 13 that is suited to the user to the connecting part 16, even if the side pressure of the sound emitting parts 10 for ears of the user is changed.
According to the headphone 1 as configured above, the end part 13A of the first side pressure supplying member 13 is inserted into the inserting hole part 16B of the connecting part 16, and thereby the engaging part 21B1 of the engaging member 21 is engaged with the engaging counterpart 13 A1 of the end part 13A. When replacing a first side pressure supplying member 13 with the one, which is selected from a plurality of the first side pressure supplying members 13 so as to supply a preferable side pressure for the user, the end part 13A of the first side pressure supplying member 13 can be easily removed from the connecting part 16 by pressing the release-operating part 22C of the releasing member 22.
As such, the adhesive property between the sound emitting part 10 and the ears of a user can be preferably improved by selecting a first side pressure supplying member 13, which is suited to the user. Also, the cumbersome replacement operation of the first side pressure supplying member 13 can be resolved by the easy attachment and removal of the first side pressure supplying member 13.
The headphone 1 according to the embodiment of the present invention includes the aforementioned removable part of the first side pressure supplying member 13 as well as a vibration preventing part, which prevents the vibration of the speaker unit from being transmitted to the headband part 12. Figs. 5 and 6 are views illustrating the vibration preventing part of the headphone according to the embodiment of the present invention.
In the headphone 1, the headband part 12, the supporting arm part 11, and the housing 10A of the sound emitting part 10 are configured with a metal member. And, the supporting arm part 11 is attached to the housing 10A via a first resin member 3. Further, the sound emitting part 10 includes the housing 10A, the speaker unit 2 attached to the housing 10A, and a covering member 10B that covers the speaker unit 2, and the covering member 10B arranged in the opposite side of the sound emission side of the speaker unit 2 and the speaker unit 2 are attached to each other via a second resin member 4. The covering member 10B may be configured with a metal member having a plurality of hole parts.
Both end parts of the supporting arm part 11 is connected with housing 10A via an attaching member 19 having a pole part and a flange part. The attaching member 19 may be fixed to the supporting arm part 11. If the supporting arm part 11 is fixed to the attaching member19, the supporting arm part 11 is rotatably connected with the sound emitting part 10 via a rod-shaped member inserted into the hole part of the attachment member 19 and arranged inside the housing 10A. The attaching member 19 and the rod-shaped member are configured with a metal member. Also, the housing 10A includes an attaching hole 10A1 in which the attaching member 19 is arranged. The first resin member 3 is provided so as to cover the periphery of this attaching member 19. The first resin member 3 has a hole into which the attaching member 19 is inserted. The attaching member 19 is inserted into the hole of this first resin member 3 and the first resin member 3 is placed between the supporting arm part 11 and the housing 10A, and thereby the vibration transmitted from the speaker unit 2 to the supporting arm part 11 can be reduced by the first resin member 3. That is, the vibration generated by the speaker unit 2 can be prevented from being transmitted to the supporting arm part 11.
Further, the covering member 10B is attached to the backside of the speaker unit 2 (opposite to sound emission side) via a spacer 10D, and a second resin member 4 is fitted in the attaching counterpart 2A arranged on the backside of the speaker unit 2 (opposite side with respect to sound emission side), and the spacer 10D and the covering member10B are attached via this second resin member 4. Thereby, the vibration transmitted from the speaker unit 2 to the covering member 10B can be reduced by the second resin member 4. That is, the vibration generated by the speaker unit 2 can be prevented from being transmitted to the covering member 10B.
The headphone 1 including such vibration preventing part can suppress the trouble of noise caused by the vibration, which is generated by the speaker unit 2 and transmitted to the sound emitting part 10 or the metal member of the headband part 12. Also, the headphone 1 can suppress the trouble of the vibration, which is generated by the speaker unit 2 and transmitted to the user via the sound emitting part 10 or the headband part 12.
As disclosed above, the embodiments of the present invention are described in detail with reference to the drawings, however, a specific configuration is not limited to these embodiments, and any modifications or alterations to design without departing from the subject matter of the present invention are included within the scope of the present invention. In the embodiments shown in the above drawings, each description can be combined unless particular contradictions or problems occur in the object, the configuration, etc. Also, the description of each drawing can be independent embodiment respectively, and the embodiment of the present invention should not be limited to one embodiment combining each drawing.
