Abstract
Breakup of an electro-acoustic transducer is disrupted by introducing discontinuities that do not conform to a configuration having n-fold radial symmetry. This may be accomplished by using irregular azimuthal spacing and/or by having a junction point of the discontinuities offset relative to the geometric center of the moving surface. The discontinuities may be implemented on one or more of the moving sound producing components, such as on a diaphragm and/or dust cap of the electro-acoustic transducer. A bridging member may be introduced to span the discontinuities to stiffen the sound producing components.
