Abstract
A plurality of speakers are linked in the present invention. The linked position of each speaker can be detected. Audio signal is input to any one of the master speakers. The master speaker synchronizes the other linked speakers, and supplies audio signals to other speakers. It also controls the delay quantity of the speaker unit of each speaker. For a single speaker, the apparent width of this array speaker system becomes twice the width, and the speaker unit spacing becomes one third the spacing. Consequently, the frequency band at which direction is controllable becomes enhanced.
Additionally, a plurality of microphone devices are linked at the top, bottom, left and right sides in the present invention. The linked position of each microphone device can be detected. Audio data is output from each microphone device to the master microphone device. The master microphone device synchronizes with other linked microphone devices, treats them as array microphones in the entire linked array microphone system, and controls the delay quantity of the microphone unit of the microphone device. For a single microphone device, the apparent width of this array microphone system becomes twice the width, and the microphone unit spacing becomes one-third the spacing. Consequently, the frequency band at which direction is controllable becomes enhanced.
