[0024] The earphones according to the embodiment will be described using the earphones 91 provided with the hook 2 of the example.

[0025] (Example)

[0026] Figure 1 1 is a diagram showing the left side of the head in a state where the earphone 91 is worn on the left auricle E of a user 92. The earphone 91 is an ear canal type wireless earphone, and has a hook 2 that is hung on the outside of the auricle E as a support.

[0027] The earphone 91 is an earphone for the left ear that is worn and used in the left auricle E. The earphone 91 for the right ear is formed to be bilaterally symmetrical and has the same structure, so the earphone 91 for the left ear will be described below.

[0028] In addition, for convenience, the up, down, front, and back directions are defined as Figure 1The direction indicated by the arrow in the middle. The left direction is from the inner side of the paper to the near side, and the right direction is from the near side of the paper to the inner side.

[0029] Figure 2 This is a stereoscopic view of the earphone 91 viewed from the lower left. Figure 3 It is an exploded stereogram.

[0030] like Figure 2 and Figure 3 As shown, the earphone 91 includes a substantially cylindrical main body 1 and a hook 2 mounted on a mounting portion 11 of the main body 1 .

[0031] The main body 1 contains Figure 3 The speaker unit SP shown and the signal processing unit not shown.

[0032] The signal processing unit wirelessly receives a sound signal output from an external sound reproduction device, and outputs the sound from the speaker unit SP.

[0033] The main body 1 has a sound tube 14 protruding obliquely to the right and front and upward at the right end. The receiver 3 is detachably mounted on the sound tube 14.

[0034] The sound output from the speaker unit SP passes through the interior of the sound tube portion 14 and is emitted to the outside from the front end of the earpiece 3 .

[0035] like Figure 3 As shown, the main body 1 includes a base 15 , a mounting portion 11 , and a flange 13 from the side of the sound tube 14 .

[0036] The base 15 is formed in a substantially cylindrical shape. The axis of the base 15 is referred to as the axis CL1. The axis CL1 coincides with the axis of the main body 1.

[0037] The mounting portion 11 is formed to have a smaller diameter than the base portion 15 and is a portion to which the hook 2 is mounted.

[0038] The flange portion 13 is formed to have substantially the same outer diameter as that of the base portion 15 .

[0039] The cross-sectional shape and the longitudinal cross-sectional shape of the mounting portion 11 are respectively as follows: Figure 4 and Figure 5 shown.

[0040] The main body 1 is formed of a hard resin or a metal. An example of the resin is ABS, and an example of the metal is aluminum.

[0041] like Figures 3 to 5 As shown, the mounting portion 11 has a plurality of protrusions 12a, which are formed to be separated in the direction of the axis CL1 (approximately in the left-right direction) of the main body 1 and extend in the circumferential direction. In this example, the plurality of protrusions 12a is two.

[0042] Specifically, the convex portions 12 a are formed at two locations, and the two locations form a pair within a range of an angle θc that is 180° apart and opposed to each other in the circumferential direction.

[0043] The range of the angle θd where the projection 12 a is not formed in the mounting portion 11 is a small-diameter peripheral portion 12 c , and the diameter of the small-diameter peripheral portion 12 c is smaller than the diameter of the base portion 15 .

[0044] In this example, the small-diameter peripheral portion 12 c is formed at two locations that are spaced apart and face each other to form a pair.

[0045] The mounting portion 11 has two recesses 12b as a set at a position between the two protrusions 12a and at a position right adjacent to the right protrusion 12a in the direction of the axis CL1. The two recesses 12b are hollowed out in an arc shape in cross-sectional shape. Thus, on the mounting portion 11, a pair of two recesses 12b are formed in a manner that they are opposed to each other at 180 degrees in the circumferential direction.

[0046] like Figure 6 As shown in FIG. 1 , the distance between the bottom portions 12b1 of the two recessed portions 12b in the direction of the axis CL1 is set as a pitch Pa. Figure 3 and Figure 4 As shown, the distance between the bottom 12b1 of the recessed portion 12b and the axis CL1, that is, the radius Ra, is the same as the radius Rb of the small-diameter peripheral portion 12c.

[0047] like Figures 2 to 4 As shown, the hook 2 has a snap-fit ​​base 21 and a hook portion 23 .

[0048] The engagement base 21 is formed in an annular shape and has a through hole 22. The hook 2 is attached to the main body 1 by fitting the through hole 22 into the attachment portion 11 of the main body 1.

[0049] The hook portion 23 is formed to extend in a direction perpendicular to the axis CL2 from the outer peripheral surface of the engagement base 21. The hook portion 23 is formed to be bent as a portion that is hooked on the outer side of the auricle E of the user 92 from the engagement base 21 toward the front end.

[0050] The hook 2 is made of a soft material and has flexibility. Examples of the soft material include silicone rubber and thermoplastic elastomer.

[0051] like Figure 3 , Figure 4 and Figure 6 As shown, the hook 2 has an engagement peripheral portion 22 a , a hook protrusion 22 b , and an escape peripheral portion 22 c on the inner peripheral surface of the through hole 22 of the engagement base 21 .

[0052] like Figure 4As shown, the engagement peripheral portion 22a is formed at two locations within the range of the opposing angle θe on the inner peripheral surface of the through hole 22. The engagement peripheral portion 22a has substantially the same inner diameter (radius Rb) as the small diameter peripheral portion 12c of the mounting portion 11 of the body 1.

[0053] The escape peripheral portion 22 c is a region formed with an inner diameter larger than the outer diameter of the convex portion 12 a of the mounting portion 11 , and is formed at intervals within a predetermined angular range at positions facing each other in the circumferential direction.

[0054] Specifically, the escape peripheral portion 22c is formed in a larger angle range in the circumferential direction than the convex portion 12a of the mounting portion 11 of the main body 1. Figure 4 In the example shown, the angle range is as large as (angle θa + angle θb).

[0055] like Figure 6 As shown, a hook convex portion 22b is formed at the central position of the engagement base 21 of the avoidance peripheral portion 22c in the direction of the axis CL2, and the hook convex portion 22b protrudes in a manner that the outer diameter of the top portion that becomes the front end is smaller than the inner diameter of the avoidance peripheral portion 22c. The cross-sectional shape of the hook convex portion 22b is a shape corresponding to the concave portion 12b of the mounting portion 11 of the main body 1, and can be engaged with the concave portion 12b. In this example, the cross-sectional shape of the hook convex portion 22b is formed into an arc shape with the same radius as the concave portion 12b.

[0056] The hook 2 is made of a flexible material, and can be elastically deformed by fingers to expand the diameter of the through hole 22 relative to the mounting portion 11 of the main body 1 , so as to pass over the flange 13 and fit into the mounting portion 11 of the main body 1 .

[0057] When the through hole 22 is inserted into the mounting portion 11, the hook protrusion 22b is engaged with any one of the plurality of recesses 12b of the mounting portion 11. Figure 6 , an example in which the hook protrusion 22 b is engaged with the recess 12 b close to the flange 13 is shown.

[0058] In this state, if Figure 4 As shown, the two protrusions 12 a of the mounting portion 11 are formed so as to be located at the circumferential center of each of the two escape peripheral portions 22 c of the hook 2 .

[0059] like Figure 4 As shown, the circumferential formation angle of the protrusion 12a, namely the angle θc, is set to be smaller than the circumferential formation angle of the avoidance peripheral portion 22c (angle θa+angle θb+angle θc), so the hook 2 can rotate relative to the main body 1 in the clockwise direction by an angle θb and in the counterclockwise direction by an angle θa.

[0060] The engagement peripheral portion 22a of the through hole 22 of the hook 2 slides and rotates relative to the small diameter peripheral portion 12c of the main body 1, or rotates with a small gap. Therefore, the hook 2 rotates around the axis CL1 with a good sense of touch in a state where there is substantially no radial movement relative to the main body 1. In this example, the axis CL2 coincides with the axis CL1 of the engagement base 21.

[0061] Figure 5 : is a diagram showing the rotation of the hook 2 relative to the main body 1 around the axis CL1 (coinciding with the axis CL2). As described above, the hook 2 can rotate within the angle range (θa+θb) relative to the main body 1. The rotation resistance of the hook 2 is set to a degree that the hook 2 does not rotate in a natural state but can rotate by the intentional operation of the user 92's fingers.

[0062] like Figure 6 As shown, by engaging the hook projection 22b of the hook 2 with any of the plurality of recesses 12b of the body 1, the attachment position of the hook 2 in the direction in which the axis CL1 of the body 1 extends can be selectively set to a preferred position for each pitch Pa.

[0063] In this example, since two recessed portions 12b are formed, Figure 6 As shown, the hook 2 can be selectively mounted at two positions, namely, a position close to the flange portion 13 indicated by a solid line and a position far from the flange portion 13 indicated by a dotted line.

[0064] Figure 7 1 is a diagram showing two different mounting states of the hook 2 relative to the axis CL1 (coinciding with the axis CL2) of the main body 1. Figure 7 (a) shows a state where the hook 2 is installed on a side away from the flange portion 13. Figure 7 (b) shows a state where the hook 2 is mounted on the side close to the flange portion 13 .

[0065] In the earphone 91, the hook 2 has flexibility, and the concave portion 12b and the hook convex portion 22b are formed at two locations spaced apart from each other in the circumferential direction. Figure 8 As shown, the two hook protrusions 22b of the hook 2 can be engaged with the recesses 12b formed at different positions in the extending direction of the axis CL1.

[0066] Thereby, the hook 2 can be attached to the main body 1 in a posture in which the axis CL1 and the axis CL2 are inclined with respect to the main body 1. The inclination angle is the angle θf.

[0067] Fig. 91 is a plan view showing the appearance of the earphone 91 with the hook 2 attached to the body 1 in an inclined posture. Specifically, the hook 2 is attached to the body 1 with the axis CL2 inclined rightwardly at an angle θf relative to the axis CL1.

[0068] Of course, the engaging recessed portion 12b of the hook convex portion 22b may be reversed so that the hook convex portion 22b is mounted in a posture where the axis CL2 is inclined at an angle θf to the right front side with respect to the axis CL1.

[0069] The direction in which the hook 2 is inclined at the angle θf with respect to the main body 1 is determined by the circumferential positions at which the two recessed portions 12 b are formed.

[0070] In this example, two recesses 12b are formed substantially opposite to each other in the front-back direction. Accordingly, the hook 2 is formed such that the hook 23 extends upward and can be hooked on the auricle E when the hook protrusion 22b is engaged with the two recesses 12b formed opposite to each other in the front-back direction.

[0071] On the other hand, for example, if two recessed portions 12 b are formed facing each other in the up-down direction, the hook 2 can be attached to the main body 1 with the axis CL2 of the hook 2 tilted to the upper right or lower right relative to the axis CL1 of the main body 1 .

[0072] As described above, the earphone 91 can relatively rotate the hook 2 with respect to the main body 1 within a range of a predetermined angle (θa+θb) around the axis CL1 of the main body 1 .

[0073] In addition, the earphone 91 can be mounted on the hook 2 at a plurality of positions with respect to the main body 1 in the extending direction of the axis CL1 of the main body 1 .

[0074] In addition, the earphone 91 can be mounted on the main body 1 such that the hook 2 is attached to the main body 1 in such a manner that the axis CL2 of the hook 2 is inclined with respect to the axis CL1 of the main body 1 .

[0075] That is, the user 92 of the headset 91 can independently set the rotational position, axial position, and inclination of the hook 2 for the mounting position of the hook 2 relative to the main body 1. In addition, the rotational position and axial position, and the rotational position and inclination can be set in combination.

[0076] Thus, the earphone 91 can adjust the attachment position and posture of the hook 2 with respect to the main body 1, so that each user can easily obtain a preferred wearing feeling.

[0077] The embodiments described in detail above are not limited to the above-described configurations, and may be modified examples without departing from the spirit of the embodiments.

[0078] The earphone 91 is not limited to the ear canal type used by inserting the earpiece 3 into the external auditory canal. The earphone 91 may be a so-called in-ear type used by wearing the main body 1 in the auricle E without the sound tube part 14.

[0079] like Figure 4 , Figure 6 and Figure 8 As shown, in the earphone 91, the recessed portion 12b and the hooking convex portion 22b that engage with each other are referred to as a recessed and convex engaging portion KB.

[0080] The concave-convex engagement between the concave portion 12b of the main body 1 and the hook convex portion 22b of the hook 2 may be in the opposite relationship. That is, in the concave-convex engagement portion KB, one side, for example, the main body 1 side may be a convex portion, and the other side, the hook 2 side, may be a concave portion.

[0081] In the above example, the concave-convex engagement portions KB are provided at two locations which are spaced apart and formed to face each other in the circumferential direction, but may be provided at three or more locations.

[0082] The cross-sectional shapes of the recessed portion 12b and the hooking protrusion 22b are not limited to the above-mentioned arc shape, and can be freely set to a triangle, a quadrilateral, or the like.

[0083] The engagement depth of the concave-convex engagement portion KB, the engagement angle range in the circumferential direction, the pitch Pa, the rotatable angle range, etc. can be freely set.

[0084] The support member is not limited to the hook 2 hooked on the outside of the auricle, but may be an arm-shaped support member engaged with the inner wall of the auricle, for example, the antihelix.

[0085] The earphone 91 is not limited to a wireless type, and may be a wired type. In the case of a wired type, for example, the wire is drawn out from the base 15 of the main body 1 to the outside, and is pulled into the inside of the hook 23 at the root of the hook 23. Then, the wire drawn into the inside of the hook 23 passes through the inside of the hook 23 and is drawn out from the front end to the outside.
