Detailed Description of the Invention The present invention is a record, tape C In this
specification, a tape is a tape used for a tape recorder. Etc.), when an audio signal is added to the
4IK-f, it is recorded on a record, a tape, etc. and the round audio signal is attenuated, and only the
performance signal is reproduced, and the audio signal is not added to the microphone. When it
is configured to play the record, the performance signal of the tape and the audio signal, it
relates to the playback device 従 来 The conventional record, the playback device of the tape is a
record, 'replays all the electrical signals stored in the tape Since the play signal and the audio
signal are simultaneously supplied at the same time, nine records, if the tape is reproduced, the
audio signal is also reproduced simultaneously with the play signal. That is, the performance of
the orchestra and the voice of the singer are simultaneously recorded, and nine records are

reproduced, and when the tape is played, the salute voice of the singer is also reproduced at the
same time as the performance of the orchestra and the circle. For that purpose, if you need a
band performance to perform a song in the family, only the band performance will be stuttered,
and 9 EndPage: 1 record, a tape will be required, and the voice recording of a normal singer will
be recorded Good records, tapes, etc. were not suitable for use. By the way, the reproducing
apparatus according to the present invention is simultaneously recorded with the performance
signal and the audio signal, and when the audio signal is added to the microphone mixing circuit
using nine records and the tape, it operates instantaneously to cut the audio signal recorded on
the record and the tape. And the audio signal of the microphone input and the performance
signal of the record, tape, etc. are reproduced. An important object of the present invention is to
provide a playback apparatus having multiple S diverse usage purposes. KTo 0 Furthermore,
other mold cost & purpose records of the present invention. To provide a playback device that
can be used for hand IiK song training WK using tapes etc. Hereinafter, one embodiment of the
present invention will be described based on the figure WiK 0IIIi mainly as a jukebox and for
home and commercial stereo playback Reproduction device used in the device ・ Amplifier
circuit 2 for recording the record, tape etc. and amplifying the round music signal, low-pass filter
3 of required cut-off frequency, 1 mix mixing circuit number for mixing microphone input to the
amplifier circuit 2 The 0 amplifier circuit 3 configured by a transistor or a vacuum tube or the
like is configured to have a required increase degree by a transistor or a vacuum tube etc. When
4t K is required, the KFi switching circuit 6 operates to record and tape If the music output is
reduced, the amount of amplification is increased by operating the switching circuit to correct
this amount. The low-pass filter 3 is a filter which has OR or LO familiar with far-off or,
additionally, the use of an IIFB is a filter having the required cut-off frequency and degree of
attenuation.
The connection method of the low pass filter 3 to the amplification circuit 2 is roughly divided
into two types. One of them is a method of connecting so that the music signal of the normal
record and tape passes through the low pass filter 3 and the music signal passes through the low
pass filter 3 when the switching circuit operates. If the switching circuit 6 is moved to cut off the
signal path of the record or tape, the low pass filter 3 should be inserted so that the low pass
filter 3 is inserted. The other method is shown in Fig. 1. The music signal on the record tape
always passes through the low pass filter 3, but the switching circuit 6 operates and only when
running the low pass filter 3 operates as a low pass filter and the switching circuit It works in a
way that works as a low-pass finder and does not work as a low-pass finder, but just stops the
music number of all frequencies a bit. As shown in the previous stage of amplification 11 name
Kl! It is also possible to continue or increase the circuit 30 next stage Kll rust. It is easy to pick up
an induction noise such as ham with filter 5 if it is connected in 18 stages, but if you pay
attention to the shield you can use it enough. The -tO output is large enough to pick up inductive
noise. Q The cut-off frequency is usually adjusted to the lowest low over-frequency of the human
speech signal, and if this frequency is too low, the record low-de, If the playing signal of the tape

becomes unnatural or too high, the sound signal of the record and the tape will not be
attenuated. Since it becomes unnatural, it is usually about 61 LII 10 at. ○ According to the result
of our experiment to 41, this attenuation degree is lowered to 116 amloat 9 degrees, and the
result that the cut-off frequency is lowered is obtained and it is round. EndPage:2! The
circuit is constituted by a microphone amplification circuit 6 which sinters an input signal
generated by a microphone of a company 4 company microphone in an amplification circuit
111ct, and a switching circuit 6 operated by the input 1-I. If the output level of this I ic Z mixer
circuit number is appropriate, it may be anywhere in the amplifier circuit, but if the input signal
from the microphone passes the low-pass filter 3, middle and high-pitched sound is eliminated
and it is always low O Next II Km than range filter 5! I'm sorry. The microphone amplification
circuit 6 is configured to amplify an output voltage (usually a number 111 VIl [) generated by the
microphone to an amplification circuit 56 ((a voltage which is difficult to detect).
The switching circuit 6 is configured to operate according to the output signal of the microphone
amplification path 4. When the input signal to the miter becomes equal to or higher than a
predetermined level, the switching circuit 6 operates to transmit the low pass filter S in the path
of music signal of reped and tape. The music signal is inserted into the middle and high range is
destroyed * is reproduced, the miter input signal is reduced to a predetermined level and d does
not operate. 1 塾 record, tape O sound and electric signal is a low pass filter! It is configured to
be reproduced as it is without passing S. これを1! To make it appear, use the switching action
of 9v-t8cR or transistor. Somewhat Oj! The delay time is designed to have a delay time of usually
1 second or less with an unnatural sound O if the delay time is not 9 seconds. The operation and
effects of the reproducing apparatus l will be described with reference to FIG. When there is no
input signal in the microphone mixing circuit 4, that is, when it does not occur toward the
microphone, the switching circuit does not operate, and the music signal company 11 of the
record and tape is reproduced. When the microphone input signal reaches a predetermined level
or more, the switching circuit 6 is automatically operated and the music signal such as a record
or tape is sent to the low pass filter 3). The middle and high tones are attenuated, the tape K11k
is sounded, and the round sound signal company is cut almost at all, and the play signal and the
music signal and the input signal are reproduced. If you speak to the microphone like this, you
will record. Since the audio signal of the tape is hardly reproduced and only the play signal and
the voice signal of the microphone are reproduced, the use of the present invention in a jukebox
or stereo reproduction device means that the jukebox and the stereo reproduction device are
simply used. It can be used to practice songs as well as friends. Furthermore, if you sing into the
microphone, the record and tape will automatically be recorded, and the voice of the nine singers
will hardly be reproduced. The orchestra 4 can practice the song 1 and does not require any
instruments. Furthermore, the singer's voice company recorded on the record and the tape is not
necessarily reproduced at all, and the attendance is reproduced, so the comparison between his
own song and the singer's song, the singer's breathing and the pipe It also has excellent effects
such as grasping how to use. Also, if you stop singing to the microphone, it will automatically

record and be recorded on a tape, and the singer will sing out.
That is, the purpose of use of the reproduction apparatus such as the jukebox or stereo used in
the present invention is diverse and the marketability is dramatically expanded to become the
nine reproduction apparatus.

DETAILED DESCRIPTION OF THE INVENTION The present invention is a record, tape (herein,
EndPage: 4 tape is a recording tape used for a tape recorder). Etc.), in particular, when an audio
signal is applied to the audio input terminal, the audio signal recorded on the record, tape, etc. is
attenuated, only the performance signal is reproduced, and the audio signal is applied to the
audio input terminal. If not, the present invention relates to a reproduction apparatus which is
recorded on a record, a tape or the like and configured to reproduce a performance signal and an
audio signal. The conventional reproducing apparatus such as a record and a tape has always
been configured to reproduce all the electrical signals recorded on the record and the tape.
Therefore, when the performance signal and the voice signal (vocal song) were simultaneously
recorded, the performance of the orchestra and the voice of the singer were always reproduced
simultaneously, and it was not possible to reproduce only the performance of the orchestra. So to
practice singing at home etc? +。 ○ JP-U-Hu 27702 (5) If a band performance is required, only
the band performance is recorded, the tape is required and the singer's singing voice is also
recorded, and the ordinary record, tape, etc. were not suitable for use. By the way, the
reproducing apparatus according to the present invention uses the performance signal and the
voice, the record on which the signal is simultaneously recorded, the tape and the like, and when
10-05-2019

the audio signal is added to the audio input terminal, the audio signal recorded on the record and
the tape is It is configured to cut and reproduce the audio signal applied to the audio input
terminal and the performance signal recorded on a record, tape or the like. An important object
of the present invention is to provide a playback device having a wide variety of uses.
Furthermore, another important object of the present invention can be easily used for practicing
the song by using a regular record tape etc! To provide a playback device. An embodiment of the
present invention will be described below with reference to the drawings. 1 is a playback device
mainly used for jukeboxes and home and commercial stereo playback devices or other playback
devices, including an amplification circuit 2 for amplifying a music signal recorded on a record
and a tape, and a required frequency characteristic The low-pass filter 3 has an audio mixing
circuit 4 for mixing an audio signal with the amplifier circuit 2. If the music output of a record, a
tape or the like is lowered, the amplification degree is increased at the time of operation of the
switching circuit 6 only by correcting this decrease. The low pass filter 3 is a filter which has the
required cut-off frequency and the degree of attenuation by combining OR or LO appropriately or
additionally using NFB.
Although a low pass filter is used in this embodiment, this filter may be a filter for attenuating
the signal of human voice frequency components, and a single band elimination filter or a high
pass filter may also be used. It is hard to be low. Furthermore, the connection method of the low
pass filter T-3 to the amplification circuit 2 is roughly divided into two. When the audio signal is
not present, the music signal of the record or the tape is reproduced without passing through the
low pass filter 3 and connected so that the music signal passes through the low pass filter 3
when the switching circuit 6 is operated. It is a method. In order to realize this, if the voice input
is added and the switching circuit 6 operates, the record signal -7 ° signal, the road
disconnection 0.3 ° disconnection part (1 · E. The low pass filter 3 may be inserted into the The
other method is as shown in FIG. 1. The music signal of the record and tape always passes
through the low pass filter 3, but the low pass filter 3 acts as a low pass filter only when the
switching circuit 6 is operated by the audio input. When the switching circuit 6 is not operating,
it does not operate as a low-pass filter, but merely operates as an attenuator that attenuates
music signals of all frequencies to some extent. EndPage: 5 There is no problem, and as shown in
FIG. 1, it may be connected to the front stage of the amplifier circuit 2 or may be connected to
the next stage of the amplifier circuit 2. If it is connected to the front stage, induction noise will
be picked up by the low pass filter 3 and hum will be generated easily, but it will not be a
problem if careful attention is paid to the shield and part arrangement. Especially when the input
signal of the input terminal 70 is large, induction noise,. If the frequency is too low, the
reproduced sound will be unnatural, and if it is too high, the audio signal recorded on the record
or tape will be somewhat reproduced. Furthermore, as the attenuation degree is also the same,
when the attenuation degree is too high, the reproduced sound becomes unnatural, so 6 dE / oct
to 12 dB / oc is usually taken as a degree. According to the result of our experiment, 12 dE / oct
is the best. The audio mixing circuit 4 is operated by an audio input terminal 7, an audio
10-05-2019
5
amplification circuit 5 connected to the input terminal, and an output signal of the amplification
circuit. And the switching circuit 6. The audio amplification circuit 5 is configured to amplify the
input voltage to a voltage suitable for mixing. However, when the input voltage is large, this
audio amplification circuit 5 is not necessary. The switching circuit 6 is configured to operate
automatically or manually according to the output signal of the audio amplification circuit.
When it is made to operate automatically by voice input, it operates when the voice input signal
becomes more than a predetermined level, and the low pass filter 3 is inserted in the passage of
the music signal of the record and the tape. The component is attenuated and reproduced, and
when the audio input falls below a predetermined level, a number of signals are reproduced
without attenuation. In order to realize this, the switching action of relays, SORs, etc.) is used. If
the operation of the switching circuit 6 does not have some delay time, the reproduced sound
will be unnatural, so it is designed to have a delay time of about 1 second or less. The operation
and effects of the reproducing apparatus 1 configured as described above will be described.
When there is no voice input signal at the voice input terminal 7, that is, when the voice is not
generated toward the microphone, the switching circuit does not operate, and the music signal
recorded on the record and the tape is reproduced as it is. However, when you sing into the
microphone, the voice input signal rises above a predetermined level, and the switching circuit 6
operates automatically, and the voice component of the music signal recorded on a record, tape,
etc. is attenuated by the low-pass filter. An audio signal recorded on a record or tape is not
reproduced, and only a performance signal and an audio signal are reproduced. If you speak to
the microphone like this, the audio signal recorded on the record I: j, j tape will not be played
back, and the performance II 1,:. I will play only the voice signal of the signal and the microphone
breath i! It is configured. For this purpose, if the present invention is used in a jukebox or other
playback device, the jukebox and the playback device can be used not only for listening to music
but also for practicing songs. Furthermore, if you sing into the microphone, the voices of the
singers recorded on the tape automatically will not be played, so many commercial singers'
voices will also be recorded using the recorded voices and tapes, and the orchestra of Furuno
Kundo You can practice the song back and do not need to play the instrument. Furthermore, by
changing the filter characteristics, it is possible to design that the voice of the singer recorded on
the record and tape can be reproduced to some extent, so that the comparison between your own
song and the singer's song can be heard. Operation effect such as grasping how to use ° two
