loudspeakers all Braun tube tiles, and that tt-e 編 is organized with the left signal and the right 1
g to carry out the stereo broadcast of Tani 15 The Therefore, 2r: the size of the television
receiver for reasons such as wanting to make one company's speaker on the right-handed
combined channel as much as possible, and wanting to increase the power of 77t77 / 08 The
drawback is that it is difficult to reduce the Book ': The purpose of the fourth proposal is an audio
multiplex television' which makes it possible to make the f-field of stereo reproduction wider
than the size of the receiver of the central pupil, giving a small size and design degree of
appearance! It is to provide i4m bonds. In this device, two speakers are placed above or below
the cathode ray tube, and one of the two speakers is aligned with the front of the television
receiver. Driven by a signal, and one other Subi (f, g $ ¥! 9 powers are arranged in one eyebrow
so that the sound comes out to the left and right with respect to the regular four in the center 1if
of the speaker of the phase signal so that the sound comes out with the reflection plate to
IKdLmg etc. The sound of these two speakers is to be 15 times in total under nitrogen. In this

device, the sound of both left and right channels is driven as two signals with 40 signals and two
running speakers, and the fP output from the speaker of the first love is in opposite phase with
the six speakers A total of 4 u rivers, and a phase signal and a front 2 ° 2-) 809: A stereo sound
field is reproduced on the front of a television receiver by synthesizing in full air. Next, another
embodiment of the present invention will be described with reference to FIG. Referring to FIG. 1,
television receiver 1 includes brown Q't2 and a speaker portion 3. Fig. 1 # (a), (b). (C) shows an
example of the speaker part attachment position, and the structure of this speaker part is as
shown in FIG. Referring to FIG. 2, this is a view seen from the speaker woman's head, lOp, etc.,

13. 4 In driven by Qb R R of left channel L and right channel R, (Speaker 12 for No. 12 and L and
KL 7) Loudspeaker for Run Double No. 13 driven by h-4. Take a look at the reflector 14.15. ■ ■
Cone speaker cone 16. Sweeten the cone 17 of the speaker for Run No. 15. The sum signal
speaker creates a sound field in front of the L 10 sound in front of the speaker, and L-h appears
on the left of the speaker for No.16. -(L-Q) comes out, 7t groove 'tLQ) back door is reflected 203-)
· λ) 81 ° 4 ti 14 and 15 The sound field of LJ-R is on the left side in front of the front panel.
The sound field of-(t, -kL), that is, 9-L, is n. The L + R and L-+ 11 t-L sound fields are synthesized
in front of the television receiver, so that the sound field of L by (L-1) + (L 4) = 2 L at the front
left and H at the right A sound field of stereo is reproduced by creating a sound field of h by (L +
R) + (R ˜i,) = 2 k. It is possible to perform almost the same stereo reproduction by repositioning
the positions of the sum signal speaker and the difference signal speaker back and forth. As
described above, the sum signal t- is applied to the forwardly-directed speaker of the two
speakers arranged at right angles with each other in the television and two-image form, and the
difference signal is applied to the leftward and rightwardly directed speaker. There is an effect
that can re-read the stereo sound field that spreads to the left and right of the screen in a smaller
space.
