[Detailed description of the invention]

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headphone which a user wears on his / her head and is used by being connected to audio equipment or the like.

[0002]

2. Description of the Related Art As is well known, a headphone of this type is provided with an annular soft elastic ear pad (or ear cushion) on its inner surface. This mounting is achieved by engaging the adhered edge formed on the outer periphery of the inner surface of the earpad with the outer periphery of the flange formed on the outer periphery of the inner surface of the housing of the headphone body. The diameter of the inner peripheral edge of the attached edge portion is in a state of being attached to the housing flange,
The flange is formed smaller than the diameter of the outer peripheral edge of the flange so that the ear pad does not come off from the flange.

[0003]

As described above, since the diameter of the inner peripheral edge of the attached edge of the earpad is smaller than the diameter of the outer peripheral edge of the flange, the supplier of the headphone replaces the earpad with the headphone body. When mounting on the flange, it is necessary to forcibly expand or extend at least a part of the inner peripheral edge of the adhered edge to the outside to engage the adhered edge with the outer peripheral edge of the flange. It is not easy, and this mounting work is not only complicated, but also the earpad may be damaged from its attached edge. Also, when the headphone user replaces the earpad or re-attaches the earpad for any reason, the same inconvenience as described above,
Although there is a drawback, the damage is likely to occur relatively easily if the outer skin of the ear pad is slightly degraded with time, particularly when the ear pad is remounted.

[0004] The present invention has an object to provide a means for attaching an earpad to a headphone body very easily and smoothly.

[0005]

The present invention comprises a headphone main body and an ear pad attached to the inner surface thereof,
A flange is formed on the outer periphery of the inner surface of the housing of the headphone body, and adhered edges are formed on the outer periphery of the inner surface of the earpad to extend inward from the outer periphery and engage with the outer periphery of the flange. Assuming that the headset has a headphone, the following features are characteristic.

Namely, the outer peripheral edge of the flange Ri Oh provided a guide notch for engaging the outer peripheral portion slides into the object to be Chakuen portion, the guide notch has an opening
Formed from first and second edges facing each other and a bottom edge
And the first edge has an arc-shaped cross section.
That point.

In a most preferred embodiment, the guide notch is formed obliquely with respect to the outer peripheral edge of the flange.

[0008]

In the present invention having the above construction, the inner surface of the headphone main body and the inner surface of the earpad are opposed to each other, and a part of the edge to be adhered is inserted into the guide notch of the flange, thereby forming the headphone main body or the earpad. Relatively, for example, when the ear pad is slid in the circumferential direction with respect to the headphone main body, the attached edge portion is guided by the guide notch portion and continuously covers the outer peripheral edge portion of the flange. ,
When this rotation becomes one rotation (360 °), the entire outer peripheral edge portion is engaged.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The headphone according to the present invention will be described in more detail with reference to the illustrated embodiment.

FIG. 1 is a perspective view of a housing 10 of a headphone main body viewed from the inside thereof without an internal mechanism such as a diaphragm and a grill, and FIG. 2 is a perspective view of an ear pad 14 viewed from the inside.

The housing 10 is formed of a hard plastic or the like into a flat circular shape, has a chamber 11 in which an internal mechanism is incorporated, and a flange 12 formed on the outer periphery of the inner surface. Such a shape and structure are known as a housing of a headphone body.

Ear pad (or ear cushion) 14
Is formed by covering a core material made of a soft elastic sponge material with an outer skin made of a soft elastic plastic sheet to form an annular shape, and forming an adhered edge portion 15 to be engaged with the outer peripheral edge portion of the flange 12 on the inner peripheral surface. I have. Such a shape and structure is known as a headphone earpad. The attached edge 15 is
A part of the outer skin as the covering material is provided by being turned inward from the outer peripheral edge of the ear pad, and the diameter of the inner peripheral edge is formed smaller than the diameter of the outer peripheral edge of the flange 12.

On the outer peripheral edge of the flange 12, a guide notch 16 having a guide function for engaging the attached edge 15 is formed obliquely with respect to the outer peripheral edge. The slant is formed so that the adhered edge 15 can be easily inserted into the guide notch 16.

FIG. 3 is an enlarged plan view of the guide notch 16, and FIG. 4 is an enlarged sectional view of the guide notch 16.

The guide notch 16, an opening 17, the first and second edges 18, 19 facing each other, and a bottom edge 20. The first edge 18 is formed in an arc shape in cross section including the corner 18a, and the second edge 19 is formed in an inclined surface 19a from the upper surface to the vicinity of the lower surface, and in the vicinity of the lower surface in an arc shape. Such a form is provided to smoothly and smoothly guide the adhered edge 15.

In the headphone according to the present invention having the above structure, as shown in FIG. 5 (see FIG. 3), the headphone body (housing 10) is gripped by one hand, and the headphone body is held by the other hand. The inner surface of the ear pad 14 faces the inner surface, and the first edge 18 of the guide notch 16 is
A part of the attached edge portion 15 is inserted through the opening 17 of the guide notch 16 so as to be located inside the inside 5. In this state, for example, when the ear pad 14 is gripped with the other hand and slid clockwise, the first edge 18 (starting edge) to the second edge 19 (ending edge)
As the turning angle to the angle increases, the outer peripheral edge of the flange 12 from the first edge 18 is continuously located inside the adhered edge 15. In other words, the attached edge portion 15 continuously covers the outer peripheral edge portion of the flange 12, and the sliding thereof is performed one round (36 times).
0 °), and the adhered edge 15 first contacting the first edge 18
When a part of the flange 12 reaches the second edge 19, the adhered edge 15 covers and engages with the entire flange 12.

[0017]

[Effect of the invention] According to the headphone according to the invention,
In order to attach the earpad to the headphone body, a notch is provided in the outer peripheral edge of the housing to insert and guide the attached edge of the earpad, and when the earpad is attached
One edge of the guide notch that rubs strongly against the adhered edge
Because it is formed in an arcuate cross section , the earpad can be attached to the headphone body very easily,
The mounting can be performed smoothly and lightly by simply sliding the headphone main body or the earpad relatively, without damaging the earpad at all. Further, since the guide notch can be formed simultaneously with the molding of the housing, the formation thereof does not cause any cost increase. Further, the housing and the ear pad are provided as engagement means.
Other than forming a guide notch on the inner periphery of the housing
To give the headphone and earpad a special structure.
The structure is very simple and suitable for low-cost mass production.
