Abstract

A headphone includes a headband, at least one headphone unit, a belt-like member and a wind-in mechanism. The headband is made from an elastically deformable material and is of an inverted U-shape. At least one headphone unit is mounted at one of the ends of the headband. When the headphone is fit onto the head a belt-like member is drawn out of the wind-in mechanism and assumes a shape that follows the shape of the head. The belt-like member is mounted in such a way that it stretches between the two ends of the headband. The wind-in mechanism automatically winds in the drawn-out belt-like member. The wind-in mechanism is mounted at a part of the headphone where one end of the belt-like member, one end of the headband and a headphone unit are joined.

Claims

1. A headphone comprising:

a headband having two ends and having an inverted U-shape;

a headphone unit mounted on at least one of the two ends of said headband;

a belt-like member having two ends mounted between the two ends of said headband, wherein the two ends of said headband are respectively joined with the two ends of said belt-like member; and

a wind-in mechanism which automatically winds in said belt-like member, said wind-in mechanism being mounted at a location where one end of said belt-like member, one end of said headband and said headphone unit are joined, whereby said belt-like member is drawn out of said wind-in mechanism when said headphone is fitted onto the head of a user and said belt-like member assumes a shape of the head, and wherein said wind-in mechanism comprises a cylindrical rotating drum having one end of said belt-like member attached thereto and which winds in said belt-like member.

2. A headphone according to claim 1, wherein said wind-in mechanism further comprises an urging member attached to said cylindrical rotating drum for constantly urging said rotating drum in a direction of winding in said belt-like member.

3. A headphone comprising:

a headband which comprises an elastically deformable member having two ends and having an inverted U-shape;

a pair of support parts each mounted at one of the two ends of said headband;

a pair of headphone units mounted respectively on said pair of support parts;

a belt-like member having two ends mounted respectively between the two ends of said headband; and

a pair of wind-in mechanisms attached respectively to the two ends of said belt-like member for automatically winding in said belt-like member, each of said pair of wind-in mechanisms being mounted inside each of said pair of support parts, and wherein each of said pair of wind-in mechanisms comprises a cylindrical rotating drum having one end of said belt-like member attached thereto for winding in said belt-like member.

4. A headphone according to claim 3, wherein each of said pair of wind-in mechanisms further comprises an urging member attached to a respective cylindrical rotating drum for respectively constantly urging said rotating drum in a direction of winding in said belt-like member.

5. A headphone according to claim 3, wherein said belt-like member comprises two first portions arranged respectively at the two ends of the belt-like member and each attached to one of said cylindrical rotating drums and which are wound in by said pair of wind-in mechanisms and a second portion which is wider than said first portions and which is arranged therebetween.
