Abstract
The present invention discloses a video/audio module applied to a computer system. The video/audio module includes a circuit board, at least one analog microphone unit, and at least one analog-to-digital converter. The analog microphone unit and the analog-to-digital converter are electrically connected and fixed to the circuit board. The analog microphone unit captures an audio signal from ambient air and converts it to an analog audio signal. The analog-to-digital converter receives the analog audio signal and transforms the analog audio signal into a digital audio signal. Because of the analog-to-digital converter, a digital microphone unit can be replaced by the analog microphone unit, thereby reducing the production cost of the video/audio module.
