Abstract
A voice input device includes a first microphone (-) that includes a first diaphragm, a second microphone (-) that includes a second diaphragm, and a differential signal generation section () that generates a differential signal that indicates a difference between a first voltage signal and a second voltage signal, the first diaphragm and the second diaphragm being disposed so that a noise intensity ratio is smaller than an input voice intensity ratio (input voice component intensity ratio), and the differential signal generation section () including a delay section (), and a differential signal output section () that generates and outputs a differential signal based on a signal delayed by the delay section.
