DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to headphones.

[0002]

2. Description of the Related Art Heretofore, headphones have been widely used in the fields of practical life and hobbies as one of audio equipment.
Normally, a pair of left and right headphones including a housing, a speaker section housed in the housing, and an ear pad attached to the outer periphery of the housing are connected to each other with a headband. In the speaker section,
It includes a diaphragm and a magnetic circuit portion including an electromagnet and a coil for vibrating the diaphragm.

[0003]

In the above-mentioned conventional headphones, in order to faithfully reproduce the original sound, a speaker section is provided in front of the entrance of the ear hole of the wearer as close as possible to the eardrum so that sound entering the ear hole can be reproduced. There is a technique that can be transmitted directly to the eardrum. According to this technique, a minute vibration sound of the diaphragm is easily transmitted, but a sound image is generated at the center of the head, which is considerably different from an out-of-head sound image that is perceived when hearing works in the natural world. Also, if it is music, it will be completely different from the sound image outside the head that is felt when listening to it at the performance hall. For this reason, the use of headphones may cause some kind of discomfort for some people. In addition, there are many cases where direct stimulation of the eardrum causes fatigue of the head as well as the ear.

Therefore, an object of the present invention is to provide a headphone capable of changing the position of a sound image and bringing it closer to an out-of-head sound image by providing a speaker portion at a position deviating from the front of the entrance of the ear canal.

[0005]

Means for solving the above problems The present invention is as follows to solve the above problems.

The present invention is based on the following features of a headphone comprising a housing, a speaker section housed in the housing, and an earpad attached to the outer periphery of the housing .

In other words, according to the present invention, the speaker section is out of a virtual space region connecting the entrances of the left and right ear holes of the headphone wearer.
Sound from the frontal side of the wearer toward the back of the head
Positioned near the forehead, inside the earpad
Crosses the spatial region obliquely and outputs the sound to the ear canal
There is provided a side wall that reflects light to the entrance of the device.

[0008]

[Action] In the headphone having such a configuration, for example, the diaphragm of the speaker unit placed on the head closer before the virtual space region, when to emit sound toward the back of the head side from the front head side, wearing headphones The person has the sound source in front of the head, and can obtain a feeling similar to the sound image outside the head.

[0009]

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS The details of the headphones according to the present invention will be described below with reference to the accompanying drawings.

[0010] FIG. 1, instrumentation of the headphones 1 according to the present invention
FIG. 3 is a side view of the wearer's head 2, in which the headphones 1 are shown in a broken state. The headphones 1 are mainly used as a pair of left and right for listening to music, and include a dome-shaped housing 3, a speaker unit 4 provided in the housing 3,
An earpad 5 covers the outer periphery of the housing 3 and is in contact with the wearer 's skin. In addition, the headphone 1 has a connection cord to the audio equipment and a headband connecting the left and right headphones 1, but these are not shown. The speaker section 4 has a diaphragm 8 and a magnetic circuit section 9 and is located on the frontal side of the ear hole entrance 10 of the wearer and emits sound toward the back of the head.

FIG. 2 is a view taken along the line XX in FIG. The speaker section 4 is provided at the entrances 10 of the left and right ear holes of the wearer.
Are located near the forehead and deviated from the space area 11 indicated by a virtual line connecting. The sound emitted from the speaker unit 4 toward the back of the head is reflected by the side wall 6 of the housing 3 obliquely intersecting with the space area 11 and enters the entrance 10 of the ear canal.

FIG. 3 is a view similar to FIG. 2, but showing a case where the position of the speaker section 4 is slightly different. The speaker unit 4 is slightly inclined with respect to the space area 11.

In the headphone 1, a speaker unit 4
May be one in which a small speaker prepared separately is attached to the housing 3.
Alternatively, the magnetic circuit unit 9 may be directly attached.
One housing 3 may be provided with two or more loudspeakers, for example, for treble and bass. Materials for the housing 3 and the diaphragm 8 include wood, fiber,
Known materials such as plastics, composite plastics, metals, and ceramics can be used. Note that the headphones 1 can be widely used not only for music appreciation but also for general use.

[0014]

In the headphone according to the present invention, the speaker section is provided outside the virtual space region connecting the entrances of the left and right ear holes, and the sound is emitted from the frontal side of the wearer to the rear side of the wearer . The sound image is outside the wearer's head and can be heard from the front, producing an effect as if listening to music at the performance hall. Moreover , inside the earpad,
Reflects sound to the entrance of the ear canal at an angle with the space area
Since the side wall is provided for
Sound is effective to the ear canal even though it is set outside the area
Can be turned on.
