1. Title of the Invention ■ Japanese Patent Application Laid-Open No. 48-522L90 Japanese
Patent Application No. 48. (1973) 7.23 Specification 1, Title 1 of the Invention, Title of the
Invention 4 Head Horn for 4-channel Stereo
4 channel stereo stereo head horn 2, number of inventions described in the claims!
8. Detailed Description of the Invention The present invention relates to the improvement of a 4channel stereo head horn. The conventional 4f yan-kiru stereo head lan-e has the front and rear
speakers or doc's in the left and right headphone cases, respectively, so that the 4f yannel sounds
independently. It is supposed to be. However, since the front speaker and the rear speaker in the
headphone case are provided close to each other, it is almost impossible to separate the front and
back sounds, and furthermore, the sound images of each channel are all in the head. Because it
can be done during the process, it gives an unpleasant feeling far from the natural sound field.
This invention eliminated such a defect and made it possible to obtain a feeling of sound near the
nature 4? It provides a headphone for a Yannel stereo. Fig. 1 s, Fig. S 概略 Overview of one
embodiment of the present invention EndPage: 1, and-1! b1 A right rear speaker 13b is provided,
and in addition, on the front scrap side of each of the housings 11a and 11b, a cushion body
14m and 14b are provided. In addition, IIs and 'flb are so-called punch metals in which holes are
formed in a mesh shape in a thin metal plate. It is not different from the conventional headphone
though. A feature of this embodiment is that each housing 11m, '1 lb is provided with a separator
5 so as to separate the sound from the front speaker and the rear speaker before and behind the
pinna. Here, the separator is inside the punched metal ISa, ISb, and the speakers 11-and 13 m
and the speaker 1! Partition 16a provided to separate the sound from b and 13b. 16b and bump
meta Azlsa and fib (7) are made up of cushion bodies l and 17b which are thrown so as to hit the
back of human ear when set. FIG. 2 is a view of the left side of the headphone as seen from the
front of the speaker, but as is also apparent from this figure, the body 14m and 171 and 8-,? N
喝 − may be configured integrally. The left and right housings are connected by a band and
integrated. When the headphones configured in this way are applied to the ear with the right arm
17m, 17b touching the back of the pinna, the sound from the front is played from the ear canal
and the sound from the back is the ear It will be played from the back side of the media, you can
hear the sound of the front and back reliably. FIG. 8 shows an embodiment of the pond according
to the present invention, and in FIG. 5 which is a further improvement to that of the above
embodiment, portions between FIG. 4 and FIG.
Tied up, front left speaker! ! The space between the back space of 1 and the front space of the
right front speaker tab and the back space of the right front speaker llb and 16- 'are similar to
those in the case of m1 and three spaces in each of the housings 11m and 11b It is best divided
into In the figure, the cross-talk sound tube 11m. The piping condition of 1 @-is a schematic
illustration of the principle, but in order not to become a genius in actual use of these, 1 For
example, a band connecting the left and right headphone cases It should just be piping integrally
with. When configured in this way, for example, if the length of the sound tube IIm, 186 is
selected as ill 6-40-, the sounds on the left and right front are each 0.6 = 1. . It also enters the
right and left ears with a duration of 5 m III. That is, left and right crosstalk occurs. As a result, it
is possible to take out the image by the blame from the front slightly from the inside of the head,
there is no unpleasant feeling, and a sound field feeling close to nature is obtained. The fourth ill
and the ** are modified examples of the eighth factor, respectively. m In Fig. 4, the left front
speaker 1! a and the right front speaker 1! The frame b is provided with only one hole, and the
crosstalk i ring 111s and llb are directly connected to the hole, respectively. Not provided. Also,
in FIG. 5, the left front and right front signals are separately added to the separately provided
Suvy * 11 m, 1 @ b, and those outputs are the front left speaker l! In the double open space of b,
the one on the right front is made to make crosstalk with the acoustic tubes 11s and 11b in the #
1 m space of the left front speaker 11-. Even in this case, as in the case of the first diagram, the
left and right blues do not become completely independent, and a natural sound field feeling
without discomfort can be obtained. Although in the above-described embodiment and modified
example, a speaker is used to reproduce a book, any other electroacoustic transducer such as a
driver may be used. As described above, according to the headphone according to the present
invention, the front and back books can be reliably divided into one, and by making parts of the
left and right plasters stick to each other, the sound image Take out S out of order 1 and get a
haunting sound field feeling without thick feeling----EndPage: 2 ′ ′ S. きる。 4, u14i of the
