DESCRIPTION JP2002101490
[0001]
BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a
headphone system capable of listening to multi-channel stereophonic sound, and more
particularly to a simulation system and game equipment for cars and aircraft as well as sound
systems such as DVD players. The present invention relates to a headphone system that can hear
three-dimensional sound that can be used for reclining equipment and the like.
[0002]
2. Description of the Related Art Conventional headphones can only hear stereo left and right
sound sources and can not hear three-dimensional sound. Also, in order to listen to stereophonic
sound with a conventional stereo headphone, there is a method of electrically shifting or delaying
the phase of the sound signal and outputting it from two or three speakers in a pseudo manner.
It was hard to become a sound image, and when I watched for a long time, mental pressure and
fatigue occurred due to a pseudo phase change and delayed sound. Also, in a typical conventional
stereophonic sound speaker system, a system consisting of six speakers in total: two front left
and right speakers, two rear left and right speakers, one center speaker, and one subwoofer
speaker It was necessary to set it up, and it was impossible to set it up in a narrow place or at the
time of movement, and it was not possible to easily hear true stereophonic sound because the
sound leaked to the outside.

SUMMARY OF THE INVENTION It is an object of the present invention to solve the abovementioned problems. Specifically, the front and rear speakers are placed diagonally or vertically
to the ear, and the sound from there is put on the ear as the front and back sounds, and the
center sound and low-range bass sound from the center speaker and the bass woofer speaker are
conducted. A headphone system capable of realistically listening to multi-channel stereophonic
sound by putting it in the ear through a sound tube is a first object of the present invention. The
second object of the present invention is to separate the sound from the front speaker and the
sound from the rear speaker by arranging a sound absorbing separator between the front
speaker and the rear speaker, and to make the front and rear parts clear. . Furthermore, it is a
third object of the present invention that vibration in the bass can be generated by attaching a
vibration generator such as a motor in the center unit.
[0004]
SUMMARY OF THE INVENTION In the present invention, front speakers 1 and 2 and rear
speakers 3 and 4 are placed obliquely or perpendicularly to the ear in right and left units 7 and
8, respectively. The center speaker 5 and the bass woofer speaker 6 are installed in the center
unit 9, and the center unit 9 and the right and left units 7, 8 are connected by the right and left
sound conduction pipes 10, 11, respectively. The center and low-range bass sounds from unit 9
pass through this sound pipe into the ear, and the sound from front speakers 1 and 2 and rear
speakers 3 and 4 in right and left units 7 and 8 goes back and forth It is a headphone system
that can be heard in the ear as a sound of, and can realistically listen to multichannel
stereophonic sound by this structure.
[0005]
The headphone of the present invention is set on the head and connected to a main body such as
a DVD player.
The center sound and low-range bass sound emitted from the center unit 9 pass through the
sound guiding tubes 10 and 11 and enter the ear through the back load portion (optional) of the
left and right units. The sounds from the front and rear speakers in the left and right units enter
the ear as front and back sounds. More specifically, a stereo audio signal of 6 channels, that is, a
front right source signal, a rear right source signal, a front left source signal, a rear left source
signal, a center source signal and a low frequency source signal is amplified by a power amplifier,
The speakers are respectively separated into a front right speaker, a rear right speaker, a front

left speaker, a rear left speaker, a center speaker, and a bass woofer speaker, and the speakers
are driven to generate stereophonic sound. In particular, the sound in the low frequency range
resonates with the back load structure 12 in the left and right units to make the sound powerful
and prevent the intrusion and return of the sound from the left and right front and rear speakers.
This structure makes it possible to realistically listen to multichannel stereophonic sound. By
separating the sound from the front and rear speakers by using a separator made of sound
absorbing sponge between the front and rear speakers of this headphone, the front and rear
sounds are separated. Keep in mind. In addition, by attaching a vibration generator such as a
motor in the center unit, it generates vibrations in the bass and exerts an effect on powerful
games and movies. With this structure, multi-channeling such as 4.3 CH is also possible. In
recent years, systems etc. in which multi-channel stereo sound is synthesized in advance into
stereo 2 CH sound source and converted into multi-channel stereo sound are increasing. In this
case, the headphone system of this structure is effective.
[0006]
DESCRIPTION OF THE PREFERRED EMBODIMENTS First Embodiment The structure of the threedimensional sound generating headphone according to the present invention will be described
with reference to FIG. 1. The front speakers 1 and 2 and the rear speakers 3 and 4 are arranged
in right and left units 7 and 8 respectively. Install at an angle or perpendicular to the As shown in
FIG. 2, the front speakers 1 and 2 and the rear speakers 3 and 4 in the right and left units 7 and
8 are placed obliquely or perpendicular to the ear 14, ie, to the cheek surface. The inclination
angle is an angle of 90 degrees or less perpendicular to the cheek surface, and 45 degrees is
preferable among them. The center speaker 5 and the bass woofer speaker 6 are installed in the
center unit 9, and the center unit 9 and the right and left units 7, 8 are connected by the right
and left sound guiding tubes 10, 11, respectively. The center sound and the low-range bass
sound emitted from the center unit 9 pass through the sound conduction tube and pass through
the back load sections 12 (optional) of the left and right units to enter the ear. The sound guide
tube 12 is intended to pass sound, and may be of a structure other than a tube. Since such a
structure is employed, four speakers, two on the left and two on the left, are conventionally
required to produce the center sound and the low-pass bass sound, but two may be sufficient in
the present invention. The sound from the front speakers 1 and 2 and the rear speakers 3 and 4
in the right and left units 7 and 8 enters the ear as front and back sounds, and this structure
enables a headphone system capable of realistically listening to multi-channel stereophonic
sound It is.

[Effect] With the headphone system structure as described above, there is no mental pressure or
fatigue due to the pseudo phase change and delay sound as in the prior art, and the multichannel is realistic even in a narrow place or when moving There is an effect that you can hear
the stereo sound of. Furthermore, no sound leaks to the outside. Also, by arranging a sound
absorbing separator between the front speaker and the rear speaker, the sound from the front
speaker and the sound from the rear speaker can be separated, and the sound between the front
and the rear can be made clear. Furthermore, by attaching a vibration generator such as a motor
to the center unit, it generates vibrations in the bass and exerts an effect on powerful games and
movies. By enlarging the structure of the present invention, it is possible to make a mini speaker
system that can be heard only by the user. Furthermore, it is possible to play CDs etc. encoded
with 3D sound with a rich 5.1 channel, and play rental video on a 5.1 channel sound field like a
DVD, and additionally, it will be sent by satellite broadcasting etc. It has the effect of being able
to play movies that have not been localized in a DVD-like 5.1 channel sound field. In addition, it is
possible to play stereo recording CD, cassette, MD, etc. in 5.1 channel sound field, and it is easy
to apply to car stereo, and all sources currently in use are used (except for mono AM radio) There
are effects that can be played back on 4 (4.1) channels or 5 (5.1) channels. In addition, both
analog and digital (DSP) can be mounted, low-cost 5.1-channel reproduction is possible, home
encoders can also be realized, and application to game machines is easy, By using the decoder
while maintaining compatibility with the above, there are effects such as multichannel being
easily possible. The application range is not only sound systems such as DVD players but also
simulation systems such as car aircrafts, game machines, recliners and so on.
