INTEGRATED CIRCUIT DEVICE, SOUND INPUTTING DEVICE AND INFORMATION PROCESSING SYSTEM

摘要

There is provided an integrated circuit device having a wiring board 1200', the wiring board 1200' including: a first vibrating membrane 714-1 which forms a first microphone; a second vibrating membrane 714-2 which forms a second microphone; and a differential signal generating circuit 720 which receives a first signal voltage obtained in the first microphone and a second signal voltage obtained in the second microphone and generates a differential signal indicating a difference between the first and second voltage signals, and a voice input device and an information processing system including the same. Accordingly, it is possible to realize a voice input element having a small size and a noise removal function with high accuracy.
