BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a block circuit diagram for explaining an
embodiment of the present invention, and FIG. 2 is a view showing an example of arrangement of
an orchestra. In the figure, 1 is a scale sound source, 2 to 4 are key switch groups, 5 to γ are
tone color circuit groups, 8 is a distribution circuit, 11 is a first speaker device, and 14 is a
second speaker device.
[Detailed description of the invention] book, four lines in the electronic musical instrument that
outputs to the tweet signal Kess beka that does the previous color of musical instruments such as
tron horn, saxophone etc., the sound of those respective instruments output is The present
invention relates to an electronic musical instrument that can be localized at a desired position in
between. Since the conventional electronic musical instrument has only one speaker device, the
standing Kr 4 is scarce. Also, in the conventional (2), for each of the upper keyboard, upper
keyboard, and foot keyboard, the musical tone 1 output from them is distributed to two signal
transmission paths by hiring as it is, and the two signal transmission paths are used. Although
there are also some that emit sound from the connected speaker devices, in Kore, for example, it
is simply superior to simple effects such as meroti being output from the left speaker and
companion contract being output from the right speaker Q) I have the disadvantage that I can
not do it. In view of the above drawbacks, it is possible to make the deduction effect the same by
making the tone signals outputted from the respective tone color circuits be at the desired J 而
between the respective 24-speaker devices. Proofing:-Make a -2 check on the work *-+
instrument. Hereinafter, an embodiment of the present invention will be described with reference
to FIG. First, one embodiment of the present invention will be described with reference to FIG. 1.
In the first embodiment, l represents a scale sound signal for outputting a plurality of musical
tone signals at intervals of half seedling, and 2 to 4 represent an upper keyboard and a lower
keyboard, respectively. -Board, foot i] il! The key switch group for the board, and the valley solidtocks of the tc and so on are connected to the neck floor sound source 1, and the movable
terminals are commonly connected for each pole, and then the timbre circuit on the mantissa
side such as trompoon and saxophone The tone color has 11 connected to us' 5 to 7 times. The
output terminals of the plurality of tone color circuits existing in these six-word color circuit
groups 5 to 7 are connected to the distribution circuit 8, and the output signals of the respective
tone color circuits in the distribution circuit 8 are 21- It is distributed to the terminals at the rate
of each place. 9 is a pre-amplifier connected to one output of a minute d self-rotation-8 to its
child n-child, and its output terminal is connected to the first speaker device 11 by valveing the
main up 10, The input terminal of the up 12 is connected to the other outgoing edge terminal of
the distribution circuit 8, and the output terminal of the up 12 is connected to the second
speaker device 14 through the main amplifier 13. A rhythm pattern signal generation circuit 15
outputs a rhythm (4) pattern No. 15 selected by the rhythm select switch-17. A rhythm sound
source 17 synchronizes with the lU recording sum pattern light. It outputs to the distribution
circuit 8 an easy r'f + M number which performs the envelope and tone of each percussion
The specific examples of the tone color circuit groups 5 to 7, the rhythm sound viRx 7 and the
distributing circuit 8 will be described with reference to FIG. 2. FIG. 2 shows an example of
arrangement of the orchestra with respect to the conductor 21. From the hill there are placed a
toron horn 22, a saxophone 23, a train l \ soto 24, a drum 25, a contra-path 26, a piano 27, a
vioron cello 28, a violin 29 and a viola 30. Accordingly, the tone color circuit groups 5 to 7 and
the rhythm sound source 17 are so structured as to be able to output the tone signal of the tone
color of the 器 --kestra li unit. For example, the tramp 24 is outputted from the upper-zero tone
circuit 哲 color-tone circuit of 5 yen, and the tone signal thereof is a second signal (5 ) The
musical tone signal output to the power device is distributed so as to be 1/9. That is, the speaker
device 11 of 弔-is disposed on the left side with respect to the m tray 1, and the second speaker
device 414 is disposed on the right side. You can hear me. In this way, the minute bt circuit 8 can
hear the bamboo of each musical instrument by appropriately setting the ratio of the musical
tone 1d outputted to the first and second speaker devices xl and 14 to each Kuri-dake mother Set
the direction. Next, in the above-mentioned configuration, the explanation will be given on the
basis of "-". According to the key operation of one child life, the scale sound source 1 controls the
color fading circuit 5 to 7 to output the distribution cycle @ 8-tone signal and is synchronized
with the rhythm pattern signal of the rhythm pattern signal generation surface 415 A job start
signal is output to the distribution circuit 8 from the speech sound g17. In the distribution circuit
8, the musical tone signal outputted from the first floor back source l and the rhythm wager 17 is
subjected to the localization of the neck of the vis-à-vis musical instrument which is emitted from
the second and the second speaker 6). 2 are distributed to the 21-output terminals of the
distribution circuit 8 so as to be the same as the arrangement of the orchestra shown in FIG. 2,
and each music piece is connected to the first and second speaker devices 11 via the
preamplifiers 9 and 12. , 14- \ output. As described above in detail, in the electronic musical
instrument according to the present embodiment, the timbre circuit of each row color circuit
group 5 to 7 and the rim tone sound 171O) and the like are the first and second speaker devices
w11 , 14 can be reduced to an orchestral deduction with a 1'r3 electronic musical instrument by
being able to set the desired desire 1- to q. In the present embodiment, some of the instruments
of the orchestra are played with the rhythm sound source 17, or all of the instruments of the
orchestra are played with the Ff sound source l. Although it is not necessary to provide one or
the amber circuit groups 5 to 7 corresponding to the orchestra's instruments, it is possible to
appropriately configure the desired tone by using the (7) circuit. Even so ugly. ?
Hibiki-1 As mentioned above, the three-dimensional e-wining machine according to this 4
proposal is i! In addition, the localization effect can be achieved by localizing the music signal
output from the visual timbre circuit and the like in the desired space between the two speaker
devices, and the effect produced is thicker (A5).
