CONDENSER MICROPHONE INCLUDING AMPLIFIER

摘要

PURPOSE: A condenser microphone including an amplifier is provided to improve the sensitivity of mike by utilizing the built-in-gain amplifier instead of conventional JFET to buffer the signal at the condenser microphone. CONSTITUTION: A condenser microphone including an amplifier includes an audio part(210). The circuit amplifies the signal of the audio circuit(210). The circuit includes an amplifier(220) and at least one capacitors(C1,C2). The amplifier(220) receives the signal from the audio part(210) and amplifies the received signal. And, the capacitors(C1,C2) are connected to the rear end of the amplifier(220).
