Abstract

In order to obtain an ear-hook headphone that is light and comfortable to wear, a supporting portion that supports a housing portion is provided in the vicinity of one end of an approximately U-shaped bend of an arm-shaped guide portion; a pushing portion that resiliently pushes from behind the auricle of a user toward the housing portion is provided in the vicinity of the other end; and a sound-outputting surface of the housing portion is disposed on the face side of the listener wearing the headphone to be approximately perpendicular to the surface formed by the bend of the arm-shaped guide portion. According to this construction, the housing portion can be easily accommodated in the earhole of the user'"'"'s ear with the guide portion being slipped along the base of the user'"'"'s ear, and the headphone can be reliably worn with the pushing portion resiliently pushing from behind his/her auricle.

Claims

1. In a headphone provided with a housing portion including an electro-acoustic transducer therein and an arm-shaped guide portion supporting said housing portion, the headphone characterized in that:

said arm-shaped guide portion has

an approximately U-shaped bend,

a supporting portion which is provided in the vicinity of one end of said bend and supports said housing portion, and

a pushing portion which is provided in the vicinity of the other end of said bend and resiliently pushes from behind the auricle of a listener toward said housing portion; and

,

a sound-outputting surface of said housing portion is disposed on the face side of a listener wearing the headphone to be approximately perpendicular to the surface formed by the bend of said arm-shaped guide portion.

2. A headphone according to claim 1, wherein

a diaphragm included in the electro-acoustic transducer within said housing portion is also disposed to be approximately perpendicular to the surface formed by the bend of said arm-shaped guide portion, and sound emitted by the vibration of the diaphragm is output from said sound-outputting surface.

3. A headphone according to claim 1, wherein

a projecting handle is provided at an end of said supporting portion, which supports said housing portion, of said arm-shaped guide portion.

4. A headphone according to claim 1, wherein

an approximately linearly projecting handle is provided at an end of said supporting portion, which supports said housing portion, of said arm-shaped guide portion, and the approximately linear handle is disposed at a predetermined angle with respect to an extended axis of said arm-shaped guide portion.

5. A headphone according to claim 1, wherein

a curved guide portion is provided at an end of the pushing portion of said arm-shaped guide portion.

6. A headphone according to claim 1, wherein

the center of said housing portion is deviated from the axis of said arm-shaped guide portion so that said housing portion is asymmetrical.

7. A headphone according to claim 1, wherein

the center of said housing portion is placed on the axis of said arm-shaped guide portion so that said housing portion is symmetrical.

8. A headphone according to claim 1, wherein

a projecting handle is provided at an end of said supporting portion, which supports said housing portion, of said arm-shaped guide portion, and a cord which supplies electric signals to said electro-acoustic transducer is pulled out from an end of said handle.

9. A headphone according to claim 1, wherein

openings of said housing portion which emit sound from the sound-outputting surface are provided only at the positions close to the earhole of the listener wearing the headphone and no other openings for emitting sound are provided at positions away from the earhole on said sound-outputting surface.

10. A headphone according to claim 1, wherein

said arm-shaped guide portion and said housing portion are integrally formed.

11. A headphone according to claim 1, wherein

a projecting handle is provided at an end of said supporting portion, which supports said housing portion, of said arm-shaped guide portion;

a cord which supplies electric signals to said electro-acoustic transducer is pulled out from said handle; and

a cord stopper is provided in said handle.
