Abstract:
A loudspeaker system constructed for controlling and shaping the acoustical waveform produced thereby, said system comprising:A. at least one loudspeaker driver for generating sound energy in response to the activation thereof; B. a housing comprising a portal zone and constructed for supportingly retaining the loudspeaker driver in cooperating relationship with the portal zone; and C. a wave shaping and controlling member comprising a. a substantially flat plate cooperatively associated with the portal of the housing, b. constructed for directly receiving the acoustical wave patterns produced by the loudspeaker driver and directed toward the portal, and controllably shaping the wave patterns by incident/coincident reflection, surface/edge diffraction, controlled variable impedance diffusion filtering, and aperture refraction, c. incorporating an acoustic reflector mounted to the flat plate and positioned extending therefrom inwardly toward the loudspeaker driver, and d. comprising a plurality of slots or baffles 1. formed in said flat plate and positioned for providing controlled, variable impedance acoustical diffusion filtering of the acoustical wave directed thereto, 2. each of said slots/baffles substantially identical in size and shape, formed in said flat plate in peripheral surrounding relationship with said acoustic reflector, and positioned in juxtaposed, adjacent, side-to-side relationship with each other defining a substantially circular array, and 3. each of said slots/baffles comprising an elongated aperture comprising a first portion comprising a substantially V-shaped edge and a second portion comprising an arcuately curved, concave edge interconnected and blended with the V-shaped edge defining the first portion; whereby a resulting final or ultimate waveform is produced which represents the acoustical summation of all factors.
