singing and the atmosphere when mixed with performance are different according to the
frequency characteristics when converting the input voice in the karaoke microphone to an
electric signal. ing.
Karaoke microphones have unique frequency characteristics by manufacturer and type, and each
has different sensitivities between bass and treble. A technique for providing a comfortable
acoustic space to the user according to such frequency characteristics is disclosed (see, for
example, Patent Document 1).
[0003]
Moreover, in the karaoke system, for the purpose of preventing interference of the wireless
microphone, for the purpose of selectively extracting only singing voice from the karaoke
microphone corresponding to a specific carrier frequency band or blocking noise. , Tone squelch
mechanism is provided.
[0004]
The tone squelch mechanism superimposes a continuous single frequency AF signal (tone) on the
modulation signal of singing voice input to the karaoke microphone and transmits it, and the
microphone receiver side transmits a band from the output of the demodulator. By selectively
extracting the tone signal by the pass filter, if the tone signal is not received, the semiconductor
switch or relay is used to shut off the power supply of the AF amplifier by cutting off somewhere
in the section from the demodulator to the speaker. It is made silent (see, for example, Patent
