Patent ID: 7848534

Claim:
A sound system comprising a plurality of sound units each including a sound signal processing section and a control section that controls the sound signal processing section, each of said plurality of sound units comprising: a connection section that connects with at least one other said sound unit to permit communication of a signal between said sound unit and the at least one other sound unit; a connection detection section that detects, via said connection section, connection between said sound unit and at least one other said sound unit; and a signal supply section that, when said connection detection section has detected connection between said sound unit and at least one other said sound unit and once a clock signal, a sound signal, and a control signal including control information are input from an upstream sound unit via said connection section, supplies the control signal to said control section, supplies the clock signal and the sound signal to said sound signal processing section and outputs the clock signal and the control signal to a downstream sound unit via said connection section, wherein, when the control signal has been supplied to said control section from said signal supply section, said control section controls said sound signal processing section, in accordance with the control information included in the control signal, so that said sound signal processing section performs, on the basis of the control information, signal processing on the sound signal and processing for outputting the sound signal to the downstream sound unit.
