DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a headphone device for auditory examination in which a sound insulation cup containing a receiver is attached to both ends of a headband portion via sound insulation cup holding members.

[0002]

2. Description of the Related Art In a conventional headphone device for audiometry,
Although a cover member made of vinyl is provided at the center of the headband portion, no cover member is provided at the joint between the headband portion and the sound insulation cup holding member and in the vicinity thereof.

[0003]

In a hearing test, if a gap is formed between the sound insulating cup and the temporal region when a headphone device for a hearing test is mounted, the sound insulating effect is reduced. In order to bring the sound insulation cup into contact with the temporal region, a metal spring material having excellent elastic properties is used for the headband portion.

[0004] However, if the headband portion, the sound insulation cup holding member, and the like are exposed as a metal spring material, the appearance and the tactile sensation are poor for a subject who undergoes a hearing test.

The present invention has been made in view of the above-mentioned problems of the prior art, and an object of the present invention is to provide a metal spring used for a headband portion, a sound insulation cup holding member, and the like. An object of the present invention is to propose a headphone device for an auditory test having good appearance and tactile sensation without exposing the material.

[0006]

SUMMARY OF THE INVENTION In order to solve the above-mentioned problems, the present invention relates to a headphone device for a hearing test, in which a sound-insulating cup containing a receiver is attached to both ends of a headband portion via sound-insulating cup holding members. The band portion and the connecting portion between the head band portion and the sound insulating cup holding member are covered with a cover member formed of rubber, synthetic resin, or the like.

[0007] The headband portion is formed by engaging three curved spring members so as to extend and contract in a substantially U-shape.
The headband portion and a coupling portion between the headband portion and the sound insulating cup holding member may be covered with a cover member formed of rubber, a synthetic resin, or the like while maintaining the headband portion in an extensible state. .

It consists of 7,7. In addition, 8 is a handle.

The headband portion 1 comprises a band-shaped center band portion 11 and a pair of left and right band-shaped side band portions 12, 12 slidably engaged with both ends of the center band portion 11, respectively. It is formed of a metal spring material having excellent elastic properties.

The center band portion 11 is formed in a substantially U-shape, and slide knobs 11a, 11a are provided at both ends. As shown in FIG. 3, the side band portion 12 is formed following the curved shape of the center band portion 11, and has an engagement piece 12a with the center band portion 11 on one end side and a sound insulation cup holding member on the other end side. 2 and a stop pin 12b.

Center band part 11 and side band part 12
Is slidably engaged with the center band 11 by holding both sides of the center band 11 with four engaging pieces 12a, as shown in FIG. Further, the connection between the side band portion 12 and the sound insulating cup holding member 2 is performed by a stopper pin 12b, and the connecting portion 5 is configured such that the sound insulating cup holding member 2 is rotatable with respect to the side band portion 12.

As shown in FIG. 1, the center cover member 6 is made of vinyl, wound around a part of the side band portions 12 and 12 from the center band portion 11, stopped by the button 6a, and attached to the head band portion 1. ing.

As shown in FIG. 2, the side cover member 7 is connected to the side band portion 12 and the sound insulation cup holding member 2 from the engagement portion between the center band portion 11 and the side band portion 12.
And is formed so as to cover up to the joint portion 5. The side cover member 7 is made of a viscoelastic polymer material such as rubber or polyester elastomer.

As shown in FIGS. 4 to 6, the side cover member 7 has a back surface portion 7a that contacts the back surface of the side band portion 12, and a side surface portion 7 that contacts the side surface of the side band portion 12.
b and a surface portion 7c in contact with the surface of the side band portion 12
And is formed following the shape of the side band portion 12.

Then, as shown in FIG. 3, the side cover member 7 is fitted to the band-shaped side band portion 12 from the back thereof, and the head band portion 1 can be expanded and contracted by operating the slide knob 11a. To do so, the surface portion 7c of the side cover member 7 is open as shown in FIG.
