DESCRIPTION JP2000295685
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
headphone equipped with a plurality of small speakers.
[0002]
2. Description of the Related Art Headphones are supported by a band so that a speaker unit is
located on the human ear. Each speaker unit includes a small speaker for outputting sound, a
cushion provided to the small speaker, and a unit case provided with the small speaker and the
cushion. The cushion prevents the sound output from the small speaker from leaking to the
outside and the sound from the outside.
[0003]
When such a headphone is worn, the cushion comes in contact with the ear and the speaker unit
pinches the head, causing a feeling of pressure on the ear and fatigue when used for a long time.
In addition, since the sound output from the small speaker directly enters the ear, the sound
image is localized in the head (particularly, in the vicinity of the back of the head).

As a headphone for solving such a defect, there is a headphone disclosed in Japanese Utility
Model Application Publication No. 63-169790. FIG. 4 is a schematic view showing a schematic
configuration of a conventional headphone. In FIG. 4A, the headphone 1 supports the unit
portion 2 provided with a small speaker for outputting sound through the rod portion 3 to the
band portion 5. The headphone 1 is attached to the head of the listener by the band unit 5, and
the unit unit 2 is disposed at a position away from the ear via the rod unit 3 from the band unit
5.
[0005]
As shown in FIG. 4B, the unit unit 2 is disposed at a position forward of the ear, and moves the
position of sound image localization from the inside of the head (in particular, near the back of
the head) to the front of the head. When four unit units 2 are used, they are disposed in front of
and behind the ear, respectively, and the position of sound image localization is moved in the
front-rear direction of the head to obtain realism.
[0006]
As shown in FIG. 4, when the headphone 1 is mounted on the head, the weight of the unit 2 and
the rod 3 is attached to the end of the band 5 (see FIG. 4A). And the pinching force of the band
portion 5 for holding the headphones 1 on the head are concentrated ("B" in FIG. 4). By
increasing the distance between the unit portion 2 and the end of the band 5, the force applied to
the end of the band 5 is increased. Therefore, the head in contact with the end of the band 5
supporting the unit 2 and the rod 3 is tightened, and the listener feels tired when the
headphones 1 are used for a long time.
[0007]
Further, in the headphone 1 shown in FIG. 4, the unit portion 2 is disposed in the band portion 5
via the rod portion 5 so as not to contact the ear, so the mounting position of the headphone 1
differs depending on the listener Depending on the size of the part, the band 5 may expand and
the position of the unit 2 may deviate from the position of the ear. In such a case, since it is
necessary to adjust the length of the band 5 and the position of the unit 2, it is complicated to
