shown in FIG. 1, the conventional display device assumes that the sound 1ll I is in the space * of
the ? fl fl fl flll D ? *, and the display with the sound source radiating in all directions. But in
reality the sound source is located in all directions! The sound then goes from all sides to the
center. Therefore, if the viewer is assumed to be in the center of the cathode ray tube, the visual
sense to see and feel the display device and the sense opposite to the auditory sense to actually
hear the sound, the display of the preferred sound field I could not say. The present invention has
been considered under the above circumstances, and the position of four or less signals to be
observed on the visual plane is simulated to the same class of the display surface of the cathode
ray tube, and the signal of the other side is generated. A display device capable of drawing a
signal that grinds toward the center of a Braun tube in proportion to a level is also O. Hereinafter,
an embodiment of the present invention will be described with reference to FIGS. In FIG. 2U),
reference numeral 21 denotes an oscilloscope, and the vertical deflection input terminal
(hereinafter abbreviated as V axis) of the oscilloscope 21 is rich in positive polarity sections as
shown in FIG. Square wave No. 1 with ? and an interphase of 2? (i hold in, the phase of this
square wave signal (11) is also shifted by ? ? / 2, the positive polarity section is ?, the
negative polarity section is wide and the period is 2t, amplitude Is to make the cathode ray tube
of the oscilloscope 21 draw a square signal 22 when the square wave signal (the square wave
signal (b same as i) is input to the horizontal deflection input terminal (hereinafter abbreviated as
H axis) Can. In addition, four square wave signals, ie, positive square wave signals (FL-V) and (FRV), in which the 1111th period of the square wave signal (&) is divided into four regions without
changing the phase. The electrode square wave signals (BR-V) and (BL-V) were input to the V axis
of the oscilloscope 21 and the 1111th period of the square wave signal (b) was divided into four
divisions without changing the phase. Four square wave signals such as negative O square wave
signal (FL-H), positive square wave signal (FR-H), (11 R-H), negative square wave signal (BL-H)
Can be manually drawn on the H axis of the oscilloscope 21 so that the square signal 22 can be
drawn on the cathode ray tube.
In this case, in the square signal 22, the signals from point A to three points are the positive
square wave signal (FL-V) input to the V axis and the negative square wave signal f input by
H9IIK, The signal from the point B to the point 0, which is drawn by the 'L-H) k, is a positive
square wave signal (, FR-V) input to the axis-and a positive square input to the H @ Wave signal
(FRH), or '/): the signal from point 0 to point D is input to the V-wheel, and 11 negative signs (BRV) input to the V wheel and positive polarity input to the H axis The signal from point D to point
A, which is drawn by the square wave signal (BR-H) of the following, is the negative square wave
signal (BL-V) input to the V axis and the negative electrode input to the H axis And a square wave
signal (BL-) 1). Therefore, the signal from point A to point B of the square signal 21 corresponds
to the sound heard from the front left side of the 4-day 7-channel stereo, and the sound coming
from the right side is heard from point B to point 0 The sound from the left side of the signal
from point tiC to the size of point D should correspond to the sound from point tiC to the point D,
and the signal from point D to point A may be made to correspond In the case of drawing a signal

that extends from the display surface 1111 of the tube to the center and the back, the abovementioned square wave signals tpt and -v) and (FL-H). ??????????????
??????? Each of (BR-1'l), (BLV), and (BL-H) K may be, for example, an audio signal mold,
so that m f distributed square fpi signals (Ft, -v). An audio signal (hereinafter abbreviated as FFL0) for outputting the sound on the left of @h of 4-channel stereo is superimposed on (FL-H), and
the signal transmission wave form q (FR-V), (FR-H) is generated. H) An audio signal (hereinafter
referred to as 'R-0') for outputting the sound on the front right side of the company's 4 channel /
channel stereo is superimposed on the square wave signal (BR-V), the mouth IR-H) In the above,
one audio signal (hereinafter abbreviated as BR-0) for outputting the right rear sound of the 4channel stereo is inserted into one, and the # power distribution type wave signal (BL-, V). ! An
audio signal (hereinafter abbreviated as BL-0) for outputting the sound on the rear left side of the
4-channel stereo may be superimposed on Y '(BL-H), according to the square wave signals
described above. When superimposing signals, as shown in FIG. 8, an audio signal 32 of negative
polarity is superimposed on a square wave signal 31 of positive polarity, and for a square 33 of
positive polarity, an audio of positive polarity is shown. It is needless to say that the signal 34 is
superimposed. The waveform 36 is a waveform obtained by amplifying the waveform 36 in
which the square wave signal 31 is superimposed on the square wave signal 31 and adjusting the
level.
A waveform 37 is a waveform obtained by amplifying the waveform 38 in which the audio signal
34 is superimposed on the square wave signal 33 and adjusting the level. The configuration will
be described based on the above idea. In FIG. 4, 41 is a 4-channel stereo, and each audio signal
(FL-0), (FR-0), (BR-0) (BL-0) of this 4-channel stereo is sent to the display signal forming circuit
42. The clock pulse signal generation circuit 43 is a clock pulse generation circuit. The clock
pulse signal from the clock pulse generation circuit 43 is guided to the 4-minute m1 circuit 44.
For example, as shown in FIG. 6, this four-minute circuit 44 has a circuit configuration of 1, that
is, four flip-flop circuits (hereinafter abbreviated as FF circuits) 51.5 !. , 53.54 are cascaded. Then,
a clock pulse signal is input to the terminal 55 of the clock input (c) of each FF circuit, and set
output terminals sg, sr, ss of each FF circuit. The square wave signal is taken out from 5g. And
said set output terminal 56, 51. The respective square wave signals extracted from III and 5G are,
for example, converted in polarity through a half-turn circuit (not shown) and led to the display
signal forming circuit 42, as required. The display signal formation circuit 42 is configured as
shown in FIG. That is, the audio signals (FL-0) and (FR-0) of each channel of 4 channel stereo.
(BR-0) and (BL-0) are emitter follower circuits -i, i.e., through forward iO die t-yal, reverse die # yes, reverse diode 63 and forward diode -4, respectively. gg. gy, ga has been entered. The output
terminal 6m for connecting to the V axis of the oscilloscope 21 is connected to the emitter
follower circuit g8, 66.61 and 611, respectively. '13 .15 and an output end 70. for connection to
the H axis. F! , F4, 7g are provided. Here, the negative-polarity audio signal (FL-0) appears at the
emitter follower circuit 65C) output end 6g, and the positive polarity audio signal (FL-0) appears
at the output end 10. Also, a negative audio signal (FIIL-0) appears at the output end 11.degree.

12 of the tapered follower circuit 66 and an output end FJl'C of the emitter follower circuit 61
has a positive audio signal (mu-o). At the output 14, the negative audio signal (IIB-0) appears. At
the output terminal 15.degree. Of the emitter follower circuit 68, a positive polarity audio signal
(BL-0) appears.
Then, each audio signal of positive polarity or employee polarity is superimposed on the square
wave signal taken out from the above-mentioned quartering circuit 44. In this case, four minutes
are given to the output terminal 9. The square wave signal taken from the circuit 440 set output
terminal IC is led as a positive square wave signal (PL-V), and the output terminal 10 is converted
into a negative square wave signal (PL?V). H) has been led. In addition, square wave signals
extracted from the output terminal 51 of the 4K circuit 440- are output to the output terminals
11 and 12 respectively as square wave signals (Fl-V) and (FB-H) with positive polarity. Is being
guided. Further, the square wave signal taken out from the 4 min 1 i 11 circuit 440 set output
terminal 5 # is converted to the negative polarity to the output end 13 and is led as a square
wave signal (IR-V) to the output end r4. Is led as a square wave signal (IIB-11) of positive
polarity, and the square wave signal extracted from the circuit 440 set output terminal 5 # for 4
minutes is respectively output to the output ends 1j and 76. Negative 0 ? 4. -The pole 110direction Jl wave signal (IIL-V), (BL-H) is led as. In the above description, for example, two output
ends is and re are taken out from the emitter follower 1 path-1 and an audio signal of negative
polarity is led to the output end # 9 and an output end rerc # i positive O Oio signal is led As this
means, using a circuit as shown in FIG. 7, an audio signal (FL-0) passing through the forward
diode 61 is input to the pace of the NPN O transistor (Trl). The output end 6g is drawn from the
collector of the transistor (Trl), and the output end 1o is lost from the emitter of the transistor
(Trl). Thus, two audio signals of different polarity can be derived. For example, a circuit as shown
in FIG. 8 may be used as a circuit for taking out an audio signal of the same polarity as the
mounted emitter follower circuit 6G. That is, the signal passing through the reverse diode 62 is
input to the pace of the NPN transistor (Tr2) and also to the pace of the NPN transistor 1 ?
(Tr8). The output end 11 is taken out of the emitter of the transistor (> 12>), and the output end
12 is taken out of the emitter of the transistor (Tr8). Therefore, outputs of the same polarity can
be led to the output terminals II, II. Then, the respective audio signals whose polarity is adjusted
are superimposed on the respective square wave signals and are led to the oscilloscope.
In this case, the output ends -j, FJ, FJ, and Fj are connected to the V axis of the oscilloscope z1,
and the output ends F #, Fj, F4, and 7g are connected to the oscilloscope 21CJH axis. Therefore,
it is possible to apply the grinding signal from the periphery of the printing screen to the center
of the cathode ray tube of the oscilloscope 21. The signal O arcs toward the center at a length
proportional to the audio signal level in each direction. According to the display device of the
above configuration, when displaying the sound field of the 4-channel stereo, if the position of
the viewer is virtually assumed in the center of the cathode ray tube, the front 2 cities 1

?writing down the black level of the display image Since the grinding signal from the four
directions can be disseminated from the four directions, the visual line of CRT viewing and the
auditory sense of listening to the stereo sound coincide with each other, and a preferable sound
field can be displayed. In the above embodiment, for example, two audio signals output from the
ether follower circuit 6J are in opposite phase and have the same phase. As shown in FIG. 9, it
can be displayed by the large or small circle as shown in FIG. 9 by shifting the audio signal of one
of the gJov axis and the H axis by t / 2 phase shift. In the embodiment, the signal of each channel
of the 4-channel stereo is drawn on the cathode ray tube, but it is not limited to the signal of
each channel of the 4-channel stereo, but it is also possible to apply a pigeon etc. Of course.
According to the present invention, the positions of four or less signals to be observed on the
visual plane as described above are simulated and set on one edge of the display surface of the
cathode ray tube, and in proportion to the respective signal levels A display device can be
provided that can draw a signal that extends towards the center of the tube.
