Abstract

PURPOSE:To sufficiently exhibit surrounding effect by making a unit provided with two receivers arranged at prescribed positions, possible attachable on a right and a left ears. CONSTITUTION:A surround headphone consists of the units 1 attachable on the right and the left ears, respectively, a part to connect the right and the left two units and to hold them on a head H, and a cord to supply an electric signal. Inside the unit 1, a front receiver 2 and a rear receiver 3 are arranged so that they are separated apart from each other in a horizontal direction by an interval larger than the mean width of the concha of a grown man, and at the same time, so that the central axes A2, A3 of sound sources intersect nearly orthogonally at the vicinity of the entrance of the external auditory miatus (a) of the man.

(Prior art and its problems) "Surround" refers to the sound field that surrounds the listener, and this creates a powerful sense of presence and spread of sound that can be experienced in movie theaters, concert halls, etc. , movement, etc. can be reproduced in a general household using sound equipment. Recently, surround functions such as those mentioned above are seen as promising in the AV (audio, visual) market, and VTR (video tape recorder) and V
There is a steady trend toward incorporating them into devices such as D (video discs), televisions, and radio-cassette players.

By the way, in order to fully demonstrate the power of the surround function, it is necessary to listen in a room with a certain size and at a certain high volume, but considering the housing situation in Japan, it is difficult to meet these conditions. It is difficult to fully satisfy this requirement, and therefore there is a need for playback using headphones.

On the other hand, attempts at surround effects began with "four-channel stereo," but at that time, the mainstream was the so-called stage type, where the sound source was set in the front and the surroundings had a sense of reverberant sound field, and the emphasis was placed on music reproduction. Because of this, the performance required of headphones was different from that of today's surround headphones.

In other words, current surround systems are designed to obtain acoustic effects in combination with video equipment, and because the focus is on the spread of sound and the movement of sound, it is required that the sound moves naturally from front to back and diagonally as well as left and right. It is something that will be done.

FIGS. 4 and 5 show the structure of a conventional 4-channel headphone, and are views from above when the headphone is worn on a person's head H. FIG. Note that the headphone portion is shown in cross section so that the internal structure can be seen.

In Figures 4 and 5, 1' is the right unit of the headphones, and inside it, a front receiver 2' and a rear receiver 3' are arranged in a straight line or at a slight shallow angle, and there are two units. The sounds emitted from the receiver are synthesized and enter the human ear canal a. Note that 4' is a pad, and the left unit is also configured in the same way.

However, in these conventional 4-channel headphones, the two receivers are simply arranged in a straight line or at a slight angle, and no consideration is given to the spacing between the two receivers. Therefore, although it is possible to reproduce the movement of left and right sounds like a general stereo,
The drawback was that it was unable to faithfully reproduce the natural movement of sound from front to back and diagonally, which is required by current surround sound.

In order to achieve the above object, the present invention includes two receivers which are spaced apart horizontally by an interval greater than the average width of the pinna and arranged so that the central axes of the sound sources are approximately perpendicular to each other near the entrance of the external auditory canal. The gist of the product is a surround headphone that is characterized by a unit that can be worn on both the left and right ears.

(Function) In the surround headphones of the present invention, the sounds emitted from the two receivers in each unit worn on the left and right ears arrive from outside the auricle, and are arranged almost orthogonally near the entrance of the human ear canal. Because of this, it is possible to reproduce the sense of presence, sound spread, movement, etc. that is the same as when playing using four speakers in a sufficiently spacious room.

In FIGS. 1 to 3, the surround headphones include a unit 1 that is attached to the left and right ears, a part that connects the two left and right units 1 and holds them on the head H,
It consists of a cord that supplies electrical signals. Inside the unit 1, the front receiver 2 and the rear receiver 3 are spaced at a distance equal to or greater than the average width of an adult's auricle (
50 mm), and the central axis A2. of the sound source. A3 is arranged so as to be substantially perpendicular to the entrance of the human ear canal a. The front receiver 2 and the rear receiver 3 are attached to each other through a front panel 5 having a substantially W-shaped cross section, and the front receiver 2 and the rear receiver 3 are attached to both sides of this front panel 5. It looks like this. In addition, the apex angle of the central chevron portion of the front panel 5 is approximately 90.
”, and also acts as a triangular partition wall to separate the sound from the front emitted from the front receiver 2 and the sound from the rear emitted from the rear receiver 3. Receiver 2. Rear receiver 3 has a small diameter of 1 diameter (actually φ13 to φ18) in order to clarify the position of the sound source and show the direction in which the sound is coming.
However, if the diameter of the receiver is made small, it becomes difficult to produce low-pitched sounds, so in that case, the receiver is provided with an acoustic circuit 8 for resonance at low frequencies to correct the acoustic characteristics. On the other hand, in the unit 1, the front receiver 2. A partition wall 6 is provided to separate and form air chambers corresponding to the rear receivers 3, and inside the air chamber, the front sound emitted from the front receiver 2 and the rear sound emitted from the rear receiver 3 are separated. This is to prevent the sound from mixing with the sound of the In addition, in the figure, 4 is a pad for bringing the unit 1 into close contact around the ear, and 7 is a connection wiring.

Thus, in the surround headphones of the embodiment, each unit 1, which is worn on the left and right ears, has a front receiver 2. Since the sound emitted from the rear receiver 3° comes from outside the auricle and is almost perpendicular to the entrance of the human ear canal a, it is possible to use four speakers in a sufficiently spacious room. It is possible to reproduce the same sense of presence, sound spread, movement, etc. as when played back. Also, front receiver 2゜rear receiver 3
The front receiver 2. is made small in diameter and brought close to a point sound source, and a triangular partition wall is formed on the front panel 6 to form a front receiver 2. In combination with measures such as separating the front of the rear receiver 3 and separating the air chamber behind the receiver by the partition wall 6, the position, direction and movement of the sound can be reproduced even more realistically.

(Effects of the Invention) As described above, in the surround headphones of the present invention, the sound sources are separated in the horizontal direction by an interval equal to the average width of the auricle, and the central axes of the sound sources are approximately perpendicular to each other near the entrance of the ear canal. Since the unit has two receivers arranged in such a way that it can be worn on the left and right ears, it provides the same sense of presence and sound spread as if played using four speakers in a sufficiently spacious room. , motion, etc. can be reproduced, and the surround function can be fully utilized.
