Abstract
An audio distributor interconnects a source of at least one electrical audio signal and a plurality of sound-producing speakers to sequentially apply the signal to each speaker in serial fashion. The distributor includes a support member having mounted on an outer surface thereof a number of interconnected conductive segments, each segment corresponding to one of the speakers. A motor rotates the support member, moving each conductive segment into contact with an electrical pickup to establish electrical communication between the segment associated with each speaker and the audio signal source. The conductive segments and their associated electrical pickups are arranged so that rotation of the support member sequentially places the conductive segments in position to cause the audio signal to be applied to at least one speaker at a time in serial fashion. With the speakers arranged to define the perimeter of a listening area mutually exclusive, serial application of the audio signal to the speakers simulates movement and spatial distribution of the sound about the listening area.
