DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a microphone in
which an input signal is transmitted by a single microphone as a stereo signal by FM radio waves.
Hereinafter, an embodiment of the present invention will be described with reference to the
drawings. In the figure, 1 is the case of the microphone, 2 ° 3 is the left and right micro i 36.
'Goofon unit, 4 input signals from 2 each microphone unit, R as human power, L + R, L-H sum
and difference signal to create a normal stereo signal signal 6 = → or di sumo signal Similarly, a
stereo modulation circuit that FM modulates the difference signal, 5 is an FM modulation circuit
that further FM modulates the output of the stereo modulation circuit 4, and 6 is the output of
the FM modulation circuit 5 to the antenna 7, and the input signal is FM An antenna circuit 8 for
wireless transmission as a stereo signal is a power switch, and 9 is a power source. With this
configuration, it is possible to pick up the sound of the left and right channels with one
microphone and transmit it as a stereo signal as an FM radio wave, so this FM radio wave is
received by a normal FM stereo lithographer. If demodulation is performed, the left and right
input signals collected by the left and right microphone units 2.3 can be independently taken out
to the output terminals of the left and right channels of the channel. However, if you want to
enjoy the date using this one microphone, you can take out the voice of each person separately
from each channel of the left and right), and one for each channel of the recording tape
separately And can have new functions that conventional microphones do not have. In addition,
since it is not possible to obtain sufficient effects if the pair of microphone units 2.3 are arranged
in the vertical direction when used, the pair of micro units 2.3 must be arranged on the left and
right outside of the case 1 It is extremely effective to provide an indication instructing use. A
concrete VC can be considered such as displaying the letters left and right on the left
and right of case 1 or color-coding the left half and the right half. As described above, according
to the present invention, it is possible to transmit input voice as a stereo signal by FM 屯 i with
one microphone, so that it is possible to realize a new function which is not provided in the
conventional microphone, and furthermore, the microphone Since the microphone itself is a
wireless microphone, superior effects can be obtained in that the restrictions on use are also
significantly eased compared to a wired microphone.
