Patent ID: 7450150

Claim:
An integrated audio/video sensor, comprising: a substrate; an image-receiving module for sensing an image; a sound-receiving module with a cavity, for sensing a sound, disposed on the substrate, wherein the image-receiving module is disposed on the sound-receiving module and comprises an outer cavity casing with a membrane thereon, a fixed inner cavity casing, and an electrical insulator between the outer cavity casing and the fixed inner cavity casing; and a signal-transforming module, disposed on the substrate and accommodated in the cavity, for transforming the received image and the received sound into an audio/video signal which comprises a video signal component and an audio signal component; wherein the signal-transforming module comprises an image-sensing chip for detecting the image and outputting the audio/video signal, an audio amplifier chip for detecting the sound, amplifying the sound detected and outputting the audio/video signal, and an audio/video processing chip for carrying out a post-processing of the audio/video signal.
