Patent ID: 6870941

Claim:
A dipole radiating dynamic speaker comprising: a frame characterized as a rigid plate with a centrally located aperture and rear surface comprising a plurality of integral standoff posts of minimal width secured to a magnet assembly comprising a front flux conductor plate, permanent magnet, and rear flux conductor plate: and a diaphragm characterized as a rigid inverted dome secured to said frame at the edge of the aperture: and a vent between said frame and said magnet assembly whereby rearward acoustic output is permitted to propagate away from said diaphragm: and a voice coil assembly secured to the center of said diaphragm disposed in an air gap within said magnet assembly: and acoustic damping material located between said magnet assembly and said frame for reducing acoustic reflections: and a pole flux conductor comprising a vent located axially whereby rearward acoustic output is permitted to propagate away from said diaphragm.
