Abstract:
1. A loudspeaker system for producing a directional beam of sound comprising a plurality of transducer mounting plates having complementary perimeter edges that allow the mounting plates to be fitted together, said complementary perimeter edges including irregularly shaped edges wherein two mounting plates can be fitted together such that an irregularly shaped edge of one mounting plate mates with an irregularly shaped edge of the other mounting plate, and a plurality of relatively small transducer elements mounted to each of said transducer mounting plates, said transducer elements being arranged in a closely spaced relationship on each of said mounting plates to form individual transducer array modules, the transducer elements of each of said transducer array modules having a center-to-center spacing that is relatively uniform throughout said array module, and outermost transducer elements of each of said transducer mounting plates being position along each of the perimeter edges of the transducer mounting plate such that a substantially uniform center-to-center spacing between transducer elements of the transducer array modules is substantially maintained across contiguous transducer array modules when the transducer array modules are fitted together by fitting together the mounting plates of the transducer array modules along their complimentary perimeter edges, wherein, when fitted together, the transducer array modules form a larger transducer array and wherein the transducer elements of each transducer array module of said transducer array can be driven by a signal input such that of each of the contiguous transducer array modules produces an acoustic output that combines with acoustic outputs of other transducer array modules to produce an acoustic output from the transducer array in the form of a focused directional beam.
