Abstract

A speaker array system which can be set up with ease and make it possible to minimize the distances between amplifiers and speakers and improve sound quality. A plurality of speakers (70-1 to 70-n) are mounted in a single speaker cabinet, and a plurality of amplifier devices (60-1 to 60-n) drive the plurality of speakers. A signal processing device (30) carries out signal processing on an input musical tone signal so as to generate acoustic beams from outputs of the plurality of speakers. A wireless transmitting device (40) and a wireless receiving device (50) are disposed on a signal line in a preceding or subsequent stage of the signal processing device, for transmitting and receiving signals by radio.

Claims
