Configuration of headphone body according to this embodiment]
FIG. 3 is an exploded perspective view of the housing and the ear pad according to the present embodiment. With reference to FIG. 3, the structure of the housing and ear pad which concern on this embodiment is demonstrated.

  As shown in FIG. 3, the cushion portion 9 has a substantially annular shape (doughnut shape) having a thickness from the inner peripheral portion 9a to the outer peripheral portion 9b. The cushion portion 9 is made of, for example, a urethane-based flexible material.

  The skin portion 10 has an insertion / removal opening 10a and a mounting hole 10b. The skin portion 10 is made of, for example, synthetic leather or cloth material.

  The insertion / removal opening 10a is formed in the outer surface side direction (see FIG. 2) of the skin part 10, and the cushion part 9 can be inserted from the insertion / removal opening 10a. Moreover, it is possible to take out the cushion part 9 from the opening 10a for insertion / removal.

  The mounting hole 10b is formed in the outer surface side direction (see FIG. 2) of the skin portion 10, and is formed on the inner peripheral side of the cushion portion 9 itself in a state where the cushion portion 9 is inserted into the skin portion 10. . Here, the inner peripheral side represents a position where the distance from the inner peripheral portion 9a is closer than the distance from the outer peripheral portion 9b. For example, the mounting hole 10b has a distance of 1 cm from the inner peripheral portion 9a. It is installed in the position within. The attachment hole 10b may be installed so as to be directly opened in the skin portion 10. Alternatively, the attachment hole 10b may be directly formed in a sheet (polyurethane-based or rubber-based stretchable material) that is harder (higher strength) than the skin part 10, and the sheet may be welded to the skin part 10. According to this, the strength in the vicinity of the mounting hole 10b can be increased. In the example shown in FIG. 3, three attachment holes 10b are formed. However, the number is not limited to three, and any number of attachment holes 10b may be formed.

  The attachment plug 41 is covered so as to cover a part of the housing 4 and is used for protecting the housing 4 and improving aesthetics.

  The front plate 6 is attached to the housing 4 with screws 61 or the like (for example, screws). A driver unit (not shown) is incorporated in the front plate 6.

  The holder portion 8 is sandwiched between the cushion portion 9 and the skin portion 10 in a state where the cushion portion 9 is inserted from the insertion / removal opening 10a. The holder part 8 is comprised by resin etc. whose intensity | strength is higher than the skin part 10, for example.

  The attachment part 7 attaches the front plate 6 and the holder part 8 of the housing 4 through the attachment hole 10b. In the example shown in FIG. 3, the attachment portion 7 is configured by a claw formed on the holder portion 8. In this case, a hole (not shown) for attaching a claw formed in the holder portion 8 is formed in the front plate 6. Moreover, the attaching part 7 is good also as being comprised by the nail | claw formed in the front board 6 to which the driver unit was attached. In this case, a hole (not shown) for attaching a claw formed on the front plate 6 is formed in the holder portion 8.

  In the example illustrated in FIG. 3, the attachment portion 7 is configured by a claw, but is not limited thereto. For example, the mounting portion 7 may be configured to include at least one of a mounting claw, a bayonet mounting member, a mounting screw, a mounting magnet, and a welding mounting portion. It is also possible to adopt a structure in which a mounting screw (such as a screw) is inserted and stopped from the housing 4 side toward the cushion portion 9 side.

  In the example shown in FIG. 3, the number of attachment portions 7 is the same as the number (three) of attachment holes 10b, but any number of attachment portions 7 may be formed.

  Thus, since the attachment part 7 is fixed to the position of the attachment hole 10b, the relative position of the ear pad 5 with respect to the housing 4 is fixed by the position of the attachment hole 10b. Therefore, the mounting hole 10b has a structure that also serves as positioning of the ear pad 5.

  As shown in FIG. 5, the ear pad 5 is attached to the front plate 6. The skin portion 10 can be configured in a bag shape in which the human body contact portion 11 covers the entire inner surface side, for example. In this case, the human body contact part 11 should just be comprised with a breathable mesh material so that the sound wave output from the driver unit which the housing 4 has reaches a user's ear. It is also possible to adopt a configuration in which one or a plurality of holes are formed in the human body contact portion 11. In that case, it is possible to arrange a screen sheet for preventing dust entry at a position in contact with the human body contact portion 11 and at a position on the housing 4 side. The human body contact portion 11 and the cover portion 12 are stitched or welded to form a matching portion 13 by sewing or welding.

Modification of this embodiment]
FIG. 7 is a diagram showing a modification of the present embodiment. A modification of the present embodiment will be described with reference to FIG.

  As shown in FIG. 7, when the attachment portion 7 is constituted by a claw formed on the holder portion 8, a configuration in which a shoulder 71 for preventing pushing-in is formed on the holder portion 8 can be adopted. As shown in FIG. 7, the shoulder 71 can be provided at both ends of the lower portion of the claw as the attachment portion 7, for example. Further, the shoulder 71 may not be integrated with the claw as the attachment portion 7 and may be configured by providing a separate projection.

  FIG. 8 is a cross-sectional view taken along line II shown in FIG. With reference to FIG. 8, the detail of the modification of this embodiment is demonstrated.

  As shown in FIG. 8, the attachment portion 7 is caught by the front plate 6 so as not to come off. Further, the shoulder 71 comes into contact with the front plate 6. When both the shoulder 71 and the front plate 6 are made of a hard resin or the like, it is possible to prevent the attachment portion 7 from being pushed into the housing 4 side. The stability of the holder portion 8 formed with the attachment portion 7 and the shoulder 71 is increased, and the stability when attaching the ear pad 5 to the front plate 6 can be enhanced.

  The headphone 1 can be applied to a neckband type and any other type of headphones.

Wearing the headphones according to this embodiment]
FIG. 9 is a diagram illustrating a state when the headphones according to the present embodiment are worn. With reference to FIG. 9, the state at the time of mounting | wearing with the headphones which concern on this embodiment is demonstrated.

  FIG. 9 particularly shows a state in which the headphones 1 are worn on the user's left ear, with the user's face as the front. As shown in FIG. 9, the size of the housing 4 does not depend on the size of the ear pad 5, and the radius of the housing 4 can be reduced. In addition, the ridge line 51 (the outer portion of the sewing matching portion 13) can be made clear by forming the sewing matching portion 13 on a surface that contacts the user's temporal region when the user wears the headphones 90. .

  As shown in FIG. 9, the driver unit 42 has, for example, one end surface (the surface that contacts the user's temporal region when the user wears the headphones 1) and the other end surface (the surface opposite to the one end surface). It can be arranged at a position close to.

[8. Effects of this embodiment]
According to this embodiment, the following effects can be obtained.

  The ridge line 51 can be made clear by forming the stitched joint portion on the surface that contacts the user's temporal region when the user wears the headphones 90, and the sealing degree of the auricle 20 by the ear pad 5 is increased. Can do. In particular, sound leakage with respect to heavy bass can be prevented.

  Since the ear pad 5 can be set without being influenced by the outer diameter of the housing 4, the ear pad 5 larger (or smaller) than the outer diameter of the housing 4 can be attached, and the degree of freedom of design (design of the housing 4) is increased. Since it is not necessary to enlarge the housing 4 of the headphone body 2 in order to enlarge the ear pad 5, the weight can be reduced.

  By making the ear pad 5 larger than the outer diameter of the housing 4, the ear pad 5 swells outside the support surface of the housing 4 when the user wears the headphones 1. As a result, the load on the outer periphery (the most standing portion) of the auricle 20 can be reduced, and a soft wearing feeling can be obtained even with the earphone 1. Since the outer periphery of the ear pad 5 can be made larger than the outer diameter of the housing 4, the width of the urethane foam inside the ear pad 5 (the difference between the outer periphery and the inner periphery) can also be increased. For this reason, it becomes possible to thicken a urethane foam. If the width of the urethane foam is small, it is easy to deform by increasing the thickness of the urethane foam, and the shape cannot be maintained.

  A state in which the urethane foam and the holder portion 8 are assembled to the ear pad 5 (the state shown in FIG. 4) is referred to as an ear cushion ASSY, and the ear cushion ASSY can be attached to the front plate 6 by the attachment portion 7 such as a claw. This facilitates attachment / detachment when the cushion portion 9 and the skin portion 10 are replaced.

  Compared with general headphones 90, the mounting strength of the headphones 1 according to this embodiment to the front plate 6 is increased. It has been confirmed by the applicants of the present application that the general headphone 90 is detached from the housing 94 when pulled with a force of 1 kgf (= 9.8 N) or less with respect to the ear pad 95. On the other hand, in the headphone 1 according to the present embodiment, it has been confirmed by the applicants of the present application that even if a force of 3 kgf (= 29.4 N) is applied to the ear pad 5 and pulled, it is not detached from the housing 4.

  In the above, the preferred embodiments of the present invention have been described with reference to the accompanying drawings, but it goes without saying that the present invention is not limited to such examples. It will be apparent to those skilled in the art that various changes and modifications can be made within the scope of the claims, and these are naturally within the technical scope of the present invention.
