An audio signal transmission/reception device collects and emits a sound and transmits and receives an audio signal via communication. It is possible to improve the user operability and reduce the size of the main body of the audio signal transmission/reception device. The audio signal transmission/reception device includes: a speaker array formed by arranging a plurality of speaker units on the lower surface of the main body; and a microphone array formed by arranging a plurality of microphones on the side surface of the longitudinal direction of the main body. The main body is supported at a predetermined height from an installation surface (such as a table surface) by a hollow leg portion exhibiting a preferable sound emission characteristic of the speaker array and mounted onto the main body.
Cette invention concerne un dispositif d~émission/réception de signal audio qui émet et reçoit un signal audio par télécommunication. Cette invention permet d~améliorer l~exploitabilité par un utilisateur du dispositif d~émission/réception de signal audio, et de réduire la taille de son corps principal. Le dispositif d~émission/réception de signal audio comprend : un réseau de haut-parleurs formé par agencement d~une pluralité d~unités de haut-parleur sur la surface inférieure du corps principal, et un réseau de microphones formé par agencement d~une pluralité de microphones sur la surface latérale du sens longitudinal du corps. Le corps principal repose à une hauteur prédéterminée à partir d~une surface d~installation (par exemple, surface d~une table) sur un pied creux présentant une caractéristique d~émission acoustique optimale du réseau de haut-parleurs et monté sur le corps principal.
