BRIEF DESCRIPTION OF THE DRAWINGS The drawings show a schematic circuit vessel m of a
microfloss apparatus which is an embodiment of the present invention. 3: voice output circuit, 4:
variable resistor, 5: microphone caging. Correction Akira 53.6. 30
DETAILED DESCRIPTION OF THE INVENTION The present invention relates to the improvement
of various types of microphone devices of dynamic, capacitor, carbon, and cristall type that
receive voice and convert the waves into voice current. Conventionally, in general, in microphone
devices, a resistor is provided in an audio output circuit for the purpose of correcting an increase
in bass sensitivity to prevent sound quality deterioration and removing ground noise of a bass
component or attenuating high frequency frequency characteristics. It is shown that the
integration is as follows: In the illustrated embodiment, a dynamic microphone is shown. This
kind of microphone includes a moving coil microphone and a ribbon microphone, and is disposed
within the microphone head 1 by voice, and when the diaphragm vibrates, a voice coil or ribbon
in the magnetic field vibrates, and a voltage corresponding to the vibration energy Is generated
through the transducer 2. In the audio voltage generation circuit 3, a carbon variable resistor can
be used as a variable resistor of a variable resistor 4 incorporated therein, and an appropriate
side portion of the microphone casing 5 for the turning or switching operation. In the
microphone device thus configured in which the dial or slide switching element is mounted at the
position, the audio voltage Kv generated from the transducer 2 is supplied from the output
terminal to the amplifier connection plug 6 through the output circuit 3 Ru. Now, if it is assumed
that the audio voltage Ev is output as a divided voltage output of 'v' as 'v', it is sufficient to
operate the variable resistor 4 to change it to the volume resistance ratio R,: R2, Therefore, when
'v is arbitrarily controlled below the voice electron Ev in the voltage-division output, the
relationship of Wv + E'v is co-V = − ′ ′ xEv (the law of ohms). R, z Vr will be compatible. The
acoustic outputs Ev, FX'v thus obtained are corrected 1 via the tone control resistor 7 and
supplied to the amplifier. At that time, if the amplifier 儒 makes the sound iim section maximum,
it can be performed exclusively on the audio output adjustment d microphone side. Furthermore,
this microphone device size also applies to wireless microphones 1-Gain A And its use-it can be
used for a wide range of things. As described above at t7), according to the microphone device
according to the present invention, since the volume adjustment mechanism is built in the
microphone, the user can adjust the volume according to his / her own need at hand. It is a
strange thing that can greatly improve the simplicity.
