Abstract
An audio conference device receives and emits sounds to perform transmission/reception of audio signals via communications. The device has a speaker array with a plurality of speakers arranged on the lower surface of an elongated main housing, and a microphone array with a plurality of microphones arranged on the side surface of the main housing along the longitudinal direction. Legs are attached to the main body to support the main housing at a prescribed height above the resting surface and to secure good sound emission characteristics of the speaker array. The device further controls directivity of the microphones.
