low-order waves in the valley phase shifters. A heat generation circuit for producing beats in the
audio input signal and phase shifters with different angles for phase shifting to a plurality of
variable resistors are all connected, and a low part 7Ei and an oscillator are all connected to this
phase shifter. It is equipped with a stereo division circuit that simultaneously supplies low

binaural effect and Yoba扛Ru effect. Just V, the binaural effect n, for kings of frequencies above
IKHz, the king feels an eagle image with a sword with large sound pressure, and for sounds of
equal sound pressure below IKHz, the phase difference is If the angle is less than 180 °, the
sound image deviates to the phase advance rL, and if it exceeds 1800 or more, the image moves
in the opposite direction. (The sound image comes to the middle 2-8 9.1 at 60 °. In addition,
about very low old-fashioned and high-ha sounds, · · · · · · · · ·, <<, it has been known that the
distinction between just before and right (not easy to mistake 9). An example of a device using a
binaural effect related to the directionality of this sound is a stereo device that simultaneously
emits two or more speakers. In this stereo device, speakers are provided at the right and left with
respect to the listening point, an alloy of different sound pressure and wave number is generated
simultaneously from this speaker, and the sound image is reciprocated between the left and right
by the change of the sound pressure. It is designed to create a wide sound of 9frsiJ. 2.
Description of the Related Art Conventionally, as a device using a binaural effect related to the
directionality of sound in addition to the above-mentioned stereo device, there is a device which
makes a plurality of 1-solid D speakers rotatable and rotates the speakers mechanically. This
device ll generates sound with different sound pressure and frequency in the valleys of multiple
speakers arranged around the listening point, and by rotating the valley speaker at the same time
V by the back pressure Ji 4 ヒLateral movement of the sound image in the left and right direction
and double reciprocating movement of the sound by the doppler effect iK in the back direction of
the sound III J @, and -2 = Yaichi: (,--creating a very special spatial sound spread Can.
In addition to this, there is a device for producing an arbitrary beater by applying phase

using a binaural effect. According to this apparatus, the electrified beat is mixed with the voice
input signal, and the sound including the beat is arranged around the listening point and
generated from the speaker, and the reciprocating movement of the bird's-eye view in the back
and forth direction by the beat effect And the spatial loudness can be made 0ki14. However, the
above Taro device has various problems. I) As to the device for mechanically rotating the speaker
V, in order to obtain the above-mentioned sound effect, it is necessary to use a plurality of
speakers for each frequency band, 0. A relatively large motor power is required to determine the
rotational drive of the straw speaker with fL. Therefore, the entire apparatus becomes large and
heavy, inconvenient for continuous transportation, and has some disadvantages of restricting the
place of use by 1-1 n, and 4-a more serious type of motor flight-4-to 2 buttons There is a
drawback that the power consumption is large depending on the application. With regard to the
device that produces the beat of the above-mentioned break point, there is an advantage that it is
lighter in weight, smaller and consumes less power as compared with a device in which the
speaker is mechanically rotated. It was not possible to create a very special holiday spatial sound
spread. In addition, even if it is possible to reciprocate the sound cliff in the back and forth
direction with respect to the listening point, the device to be generated in this beat can not
reciprocate the sound image in the left and right direction V′C. E., M number of speakers, and

human power signal, and a phase shifter with different angles that appropriately phase shift to
multiple variable resistors. Then, connect a low frequency oscillator to this phase shifter and
simultaneously make a low phase transition to the valley phase shifter? By dividing the audio
input signal into a plurality of different anti-phase 1M numbers by low noise, the split circuit and
kv4 are connected, and the electronic circuit is appropriately connected to input an audio manual
signal. A sound field generation system is provided in which a special electrical processing is
applied to an audio output signal, and a speaker r through the output signal generates a special
electronic sound effect.
Mano, the purpose of the present invention is not a mechanical device V, but a purely electrical
device, and so on. provide. f) The purpose of the present invention is to obtain various special
electronic sisters and children from 7 to 2) by properly fulfilling the life cycle circuit before and
after the stereo division circuit. Provide a private venue creation ceremony. 6- 1) Furthermore,
the place to be used in the present invention is lightweight. It is not small in size and has various
applications. For example, it can be used for sound generator of electronic guitars such as
electric guitars and electronic olcans, conventional stereo equipment, etc., and provides a

sound field creation device 4 in the case of sounding three or more speakers 5.6 is also H, and in
that case, the stereo dividing circuit 8 day variable resistor 21 ° 22, the output amplifier 25.26
It is preferable to use the audio signal output terminal 27.28 and the phase shifter 23 in
particular, and for the phase shifter 23, it is preferable to use one in which the phase shift angle
of the valley phase shifter is sequentially shifted. Further, although the connection between the
