Abstract
A voice input device, a method for manufacturing the same, and an information processing system are provided. The voice input device has a function of removing a noise component and includes a first microphone-that includes a first vibrating membrane, a second microphone-that includes a second vibrating membrane, and a differential signal generation sectionthat generates a differential signal between a first voltage signal and a second voltage signal. The first and second vibrating membranes are disposed so that a noise intensity ratio is smaller than an input voice intensity ratio that represents the ratio to intensity of an input voice component. The differential signal generation sectionincludes a delay sectionand a differential signal output sectionthat generates and outputs a differential signal with respect to a signal to which a delay is applied by the delay section.
