Claims19
A loudspeaker comprised of a diaphragm mounted to a frame and coupled with a voice coil disposed within flux gap formed by a magnet assembly, the diaphragm including a front surface and a rear surface, and the surface is coated with a thin film being comprised of one or more layers of material that is relatively more conductive than the material of the diaphragm, the thin coating having surface with low contact resistance for preventing oxidation.
A loudspeaker comprised of a diaphragm mounted to a frame and coupled with a voice coil disposed within flux gap formed by a magnet assembly, and a structure disposed rearward of, and in close proximity to, the diaphragm for absorbing energy, the structure being comprised of a plurality of curved, deflector elements.
An apparatus for quieting noise from a fan or blower used to remove heat from electrical or electronic equipment comprising a fixed, array of curved deflectors mounted in a radial fashion.
