Abstract:
A voice sound input apparatus, adapted to be inputted a sound and configured to output sound data, includes: a display unit; a first microphone, related to a first sound hole; a second microphone, related to a second sound hole; a signal processing unit; and a microphone holding unit, formed with the first sound hole, and adapted to extend toward a sound source predicted position; wherein a distance between the first sound hole and the second sound hole is a distance that a phase component of a sound strength ratio is lower than or equal to 0 dB, the sound strength ratio being a ratio between a strength of a sound component contained in 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.
