DETAILED DESCRIPTION OF THE INVENTION The present invention has successfully converted
the sound signal to 1% with respect to a roaring signal transformation device designed to
convert, for example, only the voice of a singer of a popular song record into the sound of a user.
I have made it possible. Conventionally, in the sound signal conversion device of this type, for
example, a record of a popular song, a sound of only a singer, the sound jllK of the user is
recorded 11! If I try to make an image sound at the position I, the user sings the singer's voice
without being completely dismissed. The voice of this singer is also simultaneous K (elf). + L)
Also, there is a drawback that the user loses his or her ability to sing when the singer's voice is
completely extinguished. In the present invention, the conventional flaws described in the above
1-7 are simply removed in view of the wandering point, and when one row roaring, the speaker
emits a voice in which the singer's voice and the user's voice are mixed, and recorded. The
terminal uses only the voice of the singer of the I-fffi line song record as the user's voice so that
nine voices can be obtained. Explain the scare case. Internally, (zR,) and (IL) are the sources of
the right and left channels of the stereo signal, respectively. Loud signal source (1 [0 and (IL)

microphone plug are respectively connected via switches (14R) and (L4L) that are turned off
when inserted and not inserted. Since the present invention is configured as described above, the
microphone plug and (4) are inserted into the microphone connector, and the movable contact
(9C) of the switch (9) is connected to the fixed contact (9a). In the case where the tochi (14R) and
(taL) are respectively turned off, the movable contacts (12 &) and (L2Lc) of the switches (12R)
and (12L) are respectively connected to the first · identification contacts (12Ra) and (12La) When
the switches (7R) and (7L) are turned on, the speakers (4n) and (4L) K respectively receive the
original signal of the right and left channels of the record from the microphone IS) A mixed
signal of the voice signal of n is supplied, this is all emitted and the voices of the user from the
microphone (8) are recorded in the recording inner core (131 () and (13 L)) to the right and left
channels mixture Identification-for example the identification of the voice of the user of the
microphone (8) by removing or attenuating only the singer's voice recorded at the same level on
the right and left channels 141 from the epic song record A signal converted signal is obtained.

Therefore, by bell-speaking the signals from the recording ladders (13R) and (13L), it is possible
to close the chopsticks obtained by converting the singer's voice into the user's voice from the
original signal record. In this case, since the speaker (4R) and (4L) is supplied with a signal in
which the audio signal from the original signal (5) and the user's microphone 8) is mixed, the
user can use the speaker (4R) and (4L) The original signal from the signal source (IR) and (IL)
