Abstract:
1. A voice sound input apparatus, adapted to be inputted a sound and configured to output sound data, comprising: a first microphone, related to a first sound hole; a second microphone, related to a second sound hole; a signal processing unit, configured to perform a signal processing based on at least one of outputs from the first microphone and the second microphone; and a wireless transmission unit, configured to transmit the sound data based on an output signal of the signal processing unit, wherein a distance between the first sound hole and the second sound hole is set so that a strength ratio between a strength of differential sound pressure of sounds entered to the first sound hole and the second sound hole and a strength of sound pressure of the sound entered to the first sound hole with respect to phase components becomes smaller than the strength ratio with respect to amplitude components in a case that the sounds have a predetermined frequency range.
