Multi-channel sound stereo sound system
3. Detailed Description of the Invention The present invention 1, 1 is a multi-channel
stereophonic writing system 11-capable of obtaining an arbitrary sense of direction in the south
with only a 2m speaker on a multichannel signal. Four electric signal sounds that can be
eavestically extended to FiI # by four channels / channels such as CD-a, BCj, RM matrix, etc. by
conventional multi-channel sound recording system, square (or rectangular) It is common to
radiate with four speakers arranged at the 4th base and direct 15-point localization to 5M% p
power or total land. This EndPage: 14 channels (two power amplifiers, two speakers and two fsignals) in the one-life system compared to the conventional two-channel and l-wage system. It is
necessary to make it unnecessary, and P4 #: In the device, it is necessary to falsify about twice as

network having the space sound 1 # transfer characteristic. If the angle ? is 1 46 ░, the angle 6
indicates that the angle O is 1 361 '. The phase characteristic is omitted because it is a one foot
group delay time characteristic in which the distance between the speaker and the ear of the
speaker can be separated. FIG. 6 shows Example 1 in which the present invention is applied to 4channel regeneration, in which CH1 and CH3 ? M connected left and right speakers C-radiate,
and CH2 and CH4 each Ume electricity-j path network 1 It is intended to give the listener 's
second desire for backward localization. Also, in general, the first speaker is a left and right
movement, and the transfer characteristic to the listener is also a left and right phantom name, so

The network shown in FIG. 7 is also an implementation town. As described above, according to
the method of the present invention, the diversionary direction localization which has
conventionally been obtained using four speakers can be realized with only two speakers, and
this has an advantage.
