INTEGRATED CIRCUIT DEVICE, VOICE INPUT DEVICE AND INFORMATION PROCESSING SYSTEM

摘要

An integrated circuit device is characterized in comprising a wiring board (1200') that includes a first vibrating membrane (714-1) that composes a first microphone, a second vibrating membrane (714-2) that composes a second microphone, and a difference signal generating unit (720) that receives a first signal voltage acquired by the first microphone and a second signal voltage acquired by the second microphone and that generates a difference signal between first and second voltage signals.
