An audio pick-up device of a condenser microphone includes a base, a resilient anti-shock mount disposed fixedly on the base, and an audio pick-up unit disposed securely on the anti-shock mount for sensing and processing sound waves to output corresponding electric signals. The audio pick-up device further includes a circuit unit that includes an impedance converter circuit board and a control circuit board. The impedance converter circuit board is disposed securely on the anti-shock mount and is connected electrically to the audio pick-up unit for converting a high-impedance output of the audio pick-up unit to a low-impedance output. The control circuit board is mounted on the base and is coupled electrically to the impedance converter circuit board for receiving and processing the electric signals therefrom.
