Abstract

There is provided a headphone including a headband having flexibility; a slider having flexibility with the headband attached at one end, and a headphone unit attached at the other end; a slide groove, arranged at an end of the headband or the one end of the slider, for guiding a circling movement of the slider with respect to the headband; and a slider guide, having rigidity higher than the headband and the slider, for holding the one end of the slider at the end of the headband so that one surface of the slider facing one surface of the headband circling moves with respect to the one surface of the headband while being engaged to the slide groove. A headphone that can be thinned while suppressing lowering of the attachment property is provided.

Claims

1. A headphone comprising:

a headband having flexibility;

a slider having flexibility with the headband attached at one end, and a headphone unit attached at the other end;

a slide groove, arranged at an end of the headband or the one end of the slider, for guiding a circling movement of the slider with respect to the headband; and

a slider guide, having rigidity higher than the headband and the slider, for holding the one end of the slider at a first end of the headband so that one surface of the slider facing one surface of the headband moves circularly with respect to the one surface of the headband while being engaged to the slide groove.

2. The headphone according to claim 1, wherein

the slide groove is formed with an engaged surface corresponding to the circling movement range of the slider;

the slider guide is arranged with an engagement portion for engaging the engaged surface by a biasing force; and

the slider guide relatively moves with respect to the slide groove according to the circling movement of the slider, and regulates the circling movement of the slider by an engagement resistance with the slide groove with the engagement portion engaged with the engaged surface.

3. The headphone according to claim 1, wherein the slider guide regulates the circling movement of the slider by a friction resistance with the slide groove while being engaged to the slide groove.

4. The headphone according to claim 1, wherein the slider guide holds the one end of the slider at the first end of the headband so that an outer peripheral surface of the slider facing an inner peripheral surface of the headband moves circularly with respect to the inner peripheral surface of the headband.

5. The headphone according to claim 1, wherein the headband and the slider have substantially the same cross-sectional shape.

6. A headphone comprising:

a headband having flexibility formed by bending a long band;

a housing, connected in a freely turning manner to an end of the headband, for emitting sound; and

an ear pad attached on a side of the housing that is opposite to the side connected with the headband, wherein

the ear pad has a thickness of greater than or equal to twice the housing.

7. The headphone according to claim 6, wherein the ear pad is formed to a size of covering an auricle of a wearer and with a cushion material filled in an interior, and is configured to contract according to a lateral pressure from the headband.

8. The headphone according to claim 6, wherein

the housing is connected to the end of the headband in a freely turning manner by a uniaxial turning mechanism, and

the ear pad is configured to absorb tilt of the housing with respect to an axial direction of the turning mechanism.
