BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to headphones in which headphone drivers are attached to both ends of a band, and more particularly to a headphone which is worn on the ear so that the band is below the chin.

[0002]

2. Description of the Related Art In conventional headphones, a headphone driver is attached to both ends of the band so that the band is supported by the head. However, since the hair is pressed by the band, the hairstyle is distorted. Was coming out. Therefore, there has been proposed a headphone of a sub-mounting type that is used by being worn around the ear so that the band is located below the chin.
This sub-type headphone has an acoustic transducer inside the housing, a so-called headphone driver, and an ear pad made of an elastic material attached along the opening of the housing is applied to the outer circumference of the ear to be joined to the housing. The band extending substantially linearly from the support point is rotated under the chin, and the elastic force of the band sandwiches the ears so that the housing is held between the two heads.
Then, the audio signal input from the audio device is converted into audio information and transmitted directly from the ear.

[0003]

[Problems to be Solved by the Invention] By the way, in this type of under-wear type headphone, since the band is almost on the same straight line as the band support point, when the headphone is worn naturally on the ear, The center of gravity comes to the front side of the housing of the headphones, and a moment that rotates to the neck side around the support point of the housing or the band is generated. Therefore, if the band is configured to be rotatable with respect to the housing or the supporting point of the band,
The user will feel uncomfortable by contacting the neck.

Further, if the band is constructed so as not to rotate with respect to the housing or the supporting point of the band, the reaction force of the moment generated as described above is applied to the ear pad, and the reaction force is applied to the pressure contact portion on the outer periphery of the ear. It will be added as a frictional force. That is, if the headphones are worn in a stable state, the rotation of the headphones is suppressed by the frictional force, the lateral pressure on the ears is increased, the user's burden is heavy, and the part to be pressed is painful when used for a long time. Was causing a problem. This is because the weight is directly applied to the earlobe in the type that uses the ear hook vine,
My ears hurt and my discomfort became even greater.

Further, since the band is connected near the center of the housing, the band must be provided away from the cheek so that the band does not hit the cheek when worn,
When I moved my head with headphones on, the band could get in the way or hit my shoulder.

The present invention has been made in view of the circumstances of the prior art as described above, and its purpose is not to burden the user even if it is used for a long time, and the band is an obstacle. It is to provide headphones that are compact and have excellent usability.

[0007]

In order to achieve the above-mentioned object, the present invention is directed to a pair of bowl-shaped housings each having a built-in headphone driver, and an annular ring formed along the outer circumference of the surface of the housing facing the ears. The ear pad includes a protruding ear pad formed of an elastic material and a U-shaped band connected to both housings and formed so as to rotate under the chin. The ear pad in a state in which the housing covers the ear with the band. In a headphone that elastically sandwiches both heads via a first part, which is rotatably joined at a position substantially corresponding to the center of gravity of the housing and extends to the ear pad part on the rear side of the housing along the curvature of the housing, And a hanger portion formed in an approximately L shape from a second portion extending downward at an angle of approximately 90 degrees from the extension portion of the first portion, The band is composed of an elastic band part extending from the part, and when the headphones are worn on the ear, the center of gravity of the hanger part and the band part is substantially vertically below the joint part of the hanger part with the housing. It is set to be positioned.

[0008]

According to the above-mentioned means, when the headphones are put on the ears, the hanger part wraps around the back side of the headphones, and the band part wraps under the chin inside the joint part with the housing from the ear pad part to put the headphones on. I will support you. Therefore, the band is not located outside the cheek, and the band portion can be formed compactly. Also,
Since the center of gravity of the integrated hanger and band is located almost vertically below the joint between the hanger housing and the housing, no moment is generated at the joint when worn on the ear, and the ear pad and its contact It is not necessary to suppress the rotation of the band part due to the frictional force with the contact part.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS An embodiment of the present invention shown in the drawings will be described below.

As shown in the front view in which a part of FIG. 1 is cut away, the headphone 1 has an elliptical housing 3 in which a known headphone driver 2 is built in, and an outer periphery of a surface of the housing 3 facing the ear. 2 and the ear pad 6 formed of an elastic body made of, for example, foaming urethane, and a position substantially hitting the center of gravity of the housing 3 as shown in a side view of a main part with a part cut away in FIG. Then, for example, an L-shaped hanger portion 9 joined by a screw 8 via an elastic material 7 such as urethane, a band portion 11 extending from an extension side end portion 10 of the hanger portion 9, and a headphone driver 2 And a cord 13 having a jack 12 at one end for connecting to an audio device. One surface of the elastic material 7 is attached to the housing 3, and the other surface is attached to the hanger portion 9.

The hanger portion 9, the band portion 11 and the so-called band 16 of the headphone 1 constitute a so-called band 16, and the supporting force when the ear pad 6 is attached to the temporal region so as to cover the ear is obtained by the elastic force of the band portion 11. ing. As can be seen from FIG. 2 and FIG. 3 which is a perspective view seen from the rear, the hanger portion 9 has a first portion formed so as to wrap around to the rear side of the housing 3 with a curvature substantially the same as the curvature of the bowl-shaped housing 3. 9a and a second portion 9b continuously extending substantially vertically downward from the first portion 9a are integrally formed.
Since the second portion 9b is formed so that the first portion 9a wraps around to the rear side of the housing 3, the second portion 9b shown in FIG.
Also, as can be seen from FIG. 3, it extends in a folded manner from the first portion 9a in parallel with the ear pad 6 (the surface),
The band portion 11 is joined to the second portion 9b, and the band portion 11 is U-shaped by connecting both the second portions. As a result, the band portion 11 is located inside the joint portion 14 formed by the screw 8 of the hanger portion 9.

As can be seen from FIG. 2, the first hanger 9a is joined by a screw 8. The elastic member 7 adhered to the housing 3 is interposed between the first hanger 9a and the first hanger 9a. It is set so that it can be slightly rotated in a direction perpendicular to the axis and can be slightly swung with respect to the surface. Therefore, the protrusion 15 is provided so as to project from the housing 3 side, the groove 20 into which the protrusion 15 is loosely inserted is formed in the first portion 9a of the hanger portion 9, and the rotation range is regulated by both. ing. The swinging direction is regulated by contact between the first portion 9a and the outer circumference of the housing 3.

As shown in the side views of FIGS. 2 and 4, the center of gravity W of the band 16 composed of the hanger portion 9 and the band portion 11 is almost equal to that of the joint portion 14 when the headphones 1 are worn on the ear. The length and weight are selected so as to be positioned vertically below, so that a moment is not applied from the band 16 to the joint portion 14 between the hanger portion 9 and the housing 3 at the time of mounting. Therefore, the force applied to the side of the head at the time of wearing is only the elastic force of the band portion 11, and the frictional force caused by the moment is not generated, so that the user is not unnecessarily burdened.

Further, as can be seen from FIG. 4, the band portion 11 is directly guided from the lower side of the ear to the lower side of the chin by the hanger portion 9 and does not pass the side of the cheek.
Even if it is located inside the joint portion 14, it does not come into contact with the cheeks and can be made compact.

In this embodiment, the hanger portion 9 is set to L
The band portion 11 is formed in a character shape and extends from the second portion 9b.
The first portion 9a may extend substantially at a right angle. These shapes are merely design changes appropriately set in relation to the center of gravity.

[0016]

As is apparent from the above description, according to the present invention configured as described above, the band does not generate a moment at the joint portion between the housing and the hanger portion, so that it can be used for a long time. Does not burden the user, and because the band is inside the joint and passes under the chin, the band is compact and easy to use. Headphones can be provided.
