Abstract
An audio apparatus has a housing including a tub-shaped recessed part having an upper surface and a wall surface formed on the upper surface. Microphones are circularly arranged in the vicinity of the wall surface inside the recessed part. Each microphone face toward a center direction of the recessed part and the upper surface so that a sound pick-up directivity is toward the center of the housing. A back side, opposite to the direction having the directivity of each microphone is open acoustically and is directed toward a direction higher than the wall surface of the tub-shaped recessed part.
