Patent ID: 7949146

Claim:
A loudspeaker transducer for receiving an electrical signal and transmitting an acoustical signal through a transmission medium, wherein said acoustical signal is representative of said electrical signal, and wherein said transducer comprises: a) a cone type direct radiating diaphragm further comprising a voice coil former having a top inside diameter and a top outside diameter and a bottom inside diameter and a bottom outside diameter, all of said diameters being disposed uniformly about a central axis; b) a transducer cone type diaphragm having an inside diameter and an outside diameter disposed uniformly about the central axis, wherein the inside diameter of the transducer cone diaphragm is firmly attached to the top outside diameter of the voice coil former, and c) a surround, comprising a flexible suspension member having an inside diameter and an outside diameter disposed uniformly about the central axis, with the inside diameter being attached to the outside diameter of the transducer cone type diaphragm, and d) a transducer basket frame uniformly disposed about the central axis and encircling the surround, further encircling the transducer cone type diaphragm, and further encircling the voice coil former, the transducer basket frame further attached to the outside diameter of the surround allowing for motion of the transducer cone type diaphragm and voice coil former relative to the stationary transducer basket frame, and e) a plug fixedly mounted within the top inside diameter of the voice coil former with respect to the transducer cone type diaphragm and voice coil former, thus allowing independent motion of the voice coil former and the cone type diaphragm with respect to the transducer basket frame and plug; and f) a boundary layer air mass regulator, g) wherein the boundary layer air mass regulator is a plug, and further wherein h) the plug comprising the boundary layer air mass regulator further comprises a lower portion and an upper portion; wherein the lower portion is essentially a cylinder; the upper portion comprises two sections; wherein the lower section of the upper portion comprises a cylinder having a diameter substantially equal to or less than the diameter of the lower portion of the plug and the upper section of the upper portion comprises a cylinder having a diameter substantially equal to or less than the diameter of the lower portion of the plug.
