VOICE INPUT DEVICE, METHOD FOR MANUFACTURING THE SAME, AND INFORMATION PROCESSING SYSTEM |
摘要 |
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 710-1 that includes a first vibrating membrane, a second microphone 710-2 that includes a second vibrating membrane, and a differential signal generation section 720 that generates a differential signal that represents a difference 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 section 720 includes a gain section 760 that applies a predetermined gain to the first voltage signal and a differential signal output section 740 that generates and outputs a differential signal between the first voltage signal, to which the predetermined gain is applied by the gain section, and the second voltage signal. |
