Patent ID: 7510047

Claim:
A matched complex speaker edge and asymmetric resonator panel in a speaker assembly, said asymmetric resonator panel having an aspect ratio of approximately 2:1 or more, a longitudinal axis, a lateral axis extending generally normal to said longitudinal axis, said longitudinal axis being the longer of the two axes, said asymmetric resonator panel comprising top and bottom panels held in spaced apart relationship by a plurality of generally straight ribs extending generally parallel to one another therebetween, said ribs extending generally at an angle to said longitudinal axis of from approximately 5 to 35 degrees, a source of acoustic vibration vibratingly associated with said asymmetric resonator panel, said complex speaker edge comprising at least two sections, a first of said sections having a first acoustic vibration damping characteristic, and a second of said sections having a second acoustic vibration damping characteristic, and said first and second acoustic vibration damping characteristics being sufficiently different from one another to produce a difference of at least about 2 percent in the average magnitude of the excursions of the respective sound level pressure-frequency curves, said angle being acoustically matched to said complex speaker edge to improve the accuracy with which said acoustic vibration is reproduced by said speaker assembly.
