[Detailed description of the invention] This invention is suitable for the speaker system suitable
for reproduction of 4 channel stereo, especially the speaker box of 111 speaker box K11ll
number, the stereo left and right signal to 15 O speakers respectively! In addition to the fact that
the phases are opposite to each other, by spatially synthesizing the sound rays by these
respective signals, a 4-channel stereo O rear sound liquid is obtained to obtain a good sound

the above K, in the listening room vagina, it is possible to dispense the front solution by the
excellent mourning pseudonymous 4-channel stereo in a sense of presence similar to a true 4channel stereo. . There is also the Matrindis 4 channel stereo system shown in FIG. 3 in ?L?
and ?L?, which are encoders EK for each signal of the stereo front left and right signals PL, FR
and the left and right signal holes of the stereo. More binary stereo left and right signals and 20

and the sum and difference signals of these signals15, matrix circuits, encoders, decoders, etc.
are expensive and IIIII noodles If you do not use things, you will not be able to do it easily;
In this device, stereo rear speaker addition (j) 4B-47303-04 gossips a plurality of O speakers into
a small box, 10 stereo speakers with stereo left and right O signals reverse to each other In
addition to be in phase, spatially combining the front fluid with each of these signals k>, there are
also 5 in O so as to obtain the rear front fluid of the 4-channel stereo. Next, this will be described
for the embodiment shown in the fourth g and the following. In 11411, U is a speaker box, and
the #i tenth X beater 8P and IIlff 20 speaker 1P are provided inside the omw plate u'o, but these

The stereo left signal L (t & is the right signal R) and the reverse phase signal -R of the stereo
right signal (or the reverse phase signal -L of the left signal) can be supplied to and 2 and 10
respectively, in this case As compared with the case where two speakers are housed in one box
shown in FIG. 4, the sense of separation is further reduced, and it is possible to spare the natural
feeling of 4-channel stereo reproduction. l) In each of the above embodiments, the absolute value

Although IK supplied the negative phase signal -R (-L), the connection of the whiss coil of the
speaker 8P was 111 opposite to that of the speaker BP to supply the right signal R (left signal L)
thereof. It may be K to do. As described above, according to the present invention, one speaker
box is provided with a number of speakers having a characteristic of 8-1 or 1 in proximity to
each other. By adding the stereo left and right signals in opposite phases to the bee force, and
combining the sound waves from the speakers by these signals into a space, it is possible to
obtain a rear sound wave of 41 channel stereo, Compared with the conventional one, the
complex matrix 1 and the expensive portal network such as electrical matrix 2 ░ (7) 4B-4730308 # are as follows. It is unnecessary, and amplification 11F! As long as two channels are

distortion inconspicuous, and the effective volume of the speaker box can be reduced as
described above, there are many advantages to the device that even good sound negative stereo
reproduction can be gathered, The acoustic effects are huge. Simple a-controls 11Il to 3 @@ of
