Abstract

PURPOSE:To prevent deterioration of high frequency component and to prevent mixture of noise by providing a vibration-electric transducer, an amplifier amplifying the output of the electric transducer, an A-D converter, a modulation means converting the output digital signal of the A-D converter into the modulated signal, and a separation means separating the control signal supplied externally into a microphone case. CONSTITUTION:The inside of the microphone case 1 is provided with the vibration-electric transducer 2, the amplifier 3 amplifying the analog electric signal from the vibration-electric transducer 2, and the A-D converter 4 converting the analog electric signal through the amplifier 3 into the digital electric signal. Moreover, a cable 6 is led to the outside of the case 1 from the A-D converter 4 and the digital electric signal is extracted as the microphone output through a wire. Thus, the possibility of signal deterioration, noise mixture, crosstalk and leakage of acoustic signal externally is precluded and the acoustic signal is sent with high definition and high fidelity. Moreover, the constitution is simplified and case of external control is offered and the external control signal is received easily and surely.
