BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a system diagram when using the device of the
present invention, 1 is a player etc., 2 is a block diagram of the device of the present invention, 3
is a stereo etc. FIG. 2 is a specific circuit diagram of the device of the present invention, in which
4 and 5 are equalizer circuits, 6 and 7 are subtraction circuits, and 8 is a microphone circuit.
[Detailed description of the invention] The present invention attempts to sing and enjoy his own
song on the background of accompaniment of a lyric stereo record or tape record. Relates to a
device that only uses it as karaoke. ゼ d Zea z / g A conventional restaurant without a single
lyrics, accompaniment recorded only in the accompaniment, or a tape record is released in a
conventional restaurant or general household, and the person sings according to the
accompaniment Singing and enjoying, devices known as karaoke are popular. The general public
can hardly think of the opportunity to sing a song in the background of an orchestra etc.
However, this karaoke machine gives the opportunity even to m "" $ W, 8-7.1 In the conventional
apparatus of this type, as described above, there are no lyrics but only accompaniment. There is
no problem if you're just looking to get accompaniment from the time you buy, and if you're
buying for the purpose of enjoying songs without songs, it's worth it. However, when you buy a
record or tape record tape, it is often the case that you want to hear the voice of a particular
singer, that is, a record containing the voice of a particular singer from the perspective of the
purchasing party When there is a song or tape, you hear the singer's song, and sometimes you
can use the same record or tape as the singer's song, use only the accompaniment, and you can
sing your own song together with the accompaniment. There is no. By the way, products close to
this purpose have recently been developed. This product is a singer's voice is recorded, you can
listen to the song of the singer when it is-0, and you can sing it yourself while accompaniment
with -10 songs at a time. . 7Ly)、Lヶ、。。 1tviit、*。。 □□。 6ものではない
。 If the cough singer and the pitch, tone and level are exactly the same, their own voice takes
precedence, but if they are not the same, their voice also comes out together. -<Even if you have
confidence in the song, whether it is in the range, the tone, or the way it is, it will be impossible
to beat the Pf プ ロ shi Naru's singer, regardless of how it is expressed. Therefore, in the product
concerned, it is hard to say that the product which can be strongly satisfied with the different
phase @ is generated by the voice of the singer coming out everywhere. The present invention
records only songs and sings a song according to tN, even if it is not necessary to purchase a
karaoke device for the sole purpose, entirely using a reflex or tape with which a singer's song is
made The present invention provides a karaoke apparatus that can exhibit the same effect.
Hereinafter, an embodiment of the present invention will be described in detail with reference to
the drawings. Fig. 1 is a system diagram showing how to use the present invention, wherein l is a
player or a tape recorder, 2 is a karaoke apparatus of the present invention, 3 is a stereo, a
receiver, etc. Further, FIG. 2M is a specific circuit diagram of the device of the present invention
shown by 2 in FIG. IN is a stereo left signal input terminal transmitted from a record or tape. RUN
is a signal input terminal of the same light. 4 is an equalizer circuit that adjusts the
accompaniment song and singer's voice broadcast from a stereo left speaker recorded at an angle
of 45g to the vertical of the groove of the record, for example to a certain frequency, level; It is
an equalizer circuit which adjusts the accompaniment tune and the voice of a singer broadcasted
from a speaker to a certain level. 6.7 compares the accompaniment tunes and singers' voices
adjusted to the equalizer circuit No. 5 level with the subtracter circuit No. #; 180 from the phase
number # 1 and compare the left and right levels if they are identical They are mutually
exclusive and do not output. Here, taking the stereo record as an example, the singer's R
injury is erased, and the accompaniment is slightly touched on why it is not erased. As well
known, the method of singing along with the companion to the record for the stereo (the side of
the vertical surface of the groove of the q chord is looking in with the left, light + resistance t '+
45 degrees square trade 6 . In this case, the singer's voice is recorded so that the left and the
right have the same characteristics. In other words, songs with the same frequency and sound
pressure are recorded in the same way on the left and right. So if you are ill Ill! From the left to
the right, when it goes to the subtractor circuit through one path, it has a phase of 180 threshold
in the light, and since it mutually offsets, it does not mean that it is not broadcast from a speaker
as a sound. Next is the accompaniment, but the way of this recording is looking into the left, the
right, the frequency, the ones of the areas of the sound different from the frequency of the main
owner, l; Even if the level characteristic is 4% in the equalizer Ij path, the reference values are
originally different, so both are different, and it will be a station that will not be erased by the
subtractor circuit in the next stage. N is a microphone terminal and 8 is the circuit. The output
terminal of the microphone circuit 8 is connected to the connection point between the output
terminal of the equalizer-1cI circuit 4.5 and the input terminal of the subtractor circuit 6.7. @
Line 1 to be in phase. 9.10 is an output terminal of the subtraction circuit 6, which is connected
to a book I tree such as stereo shown at 3 in FIG.
As is apparent from the above description, the karaoke apparatus of the present invention is
characterized in that the player such as stereo record or tape uses the singer's voice .sigma. A
microphone circuit 8 is provided so that the phase of the signal is inverted and output so as to
offset l, and a large number of 2 '.. Because they are connected so as to be in the same phase as
6.75r, even if the singer's song is recorded on a record or tape 6, the cough record or tape power
is used for this invention N; It is extremely economical because it is sharp. In addition, the Fcircuit unit 112 becomes a more enjoyable device by adding a part of the voice changer to the
device of the present invention. Brief description of the 4 □□□ surface 軛 1 is a system stop
when the device of the present invention is used l is a player, etc., 2 is a device of the present
invention, and the perspective figure 3 is a stereo etc. jj-i2fQ is a typical circuit diagram of the
device of the present invention, wherein 4.5 is an equalizer L + field, 6.7 is a subdivision circuit,
and 8 is a microphone 1-i path. −、:[ゆ□オ+(fj1)Ill[! □ − − − − ω ← 七
