INTEGRATED CIRCUIT DEVICE, VOICE INPUT DEVICE AND INFORMATION PROCESSING SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide an integrated circuit device capable of accomplishing a voice input element which has a small outer form and includes a highly accurate noise canceling function, and to provide a voice input device and information processing system.

SOLUTION: The present invention relates to an integrated circuit device which has 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 indicating a difference between first and second voltage signals.
