A second pin 22h and a third pin 22c of a microphone body 20, which has a 3-pole output connector, is connected with current regulative diodes D2 and D3 as a feed circuit for the drain D of the FET Q1. A first AC coupling electrolytic capacitor C3 is connected to one of the current regulative diodes, D2, and a series circuit of a second AC coupling electrolytic capacitor C4 and a resistive element R3 is connected between the anode of the other current regulative diode D3 and a ground line L3. The resistive element R3 has substantially the same impedance as an output impedance of the transistor Q2.
