Patent attributes
A low profile loudspeaker transducer is presented with an arrangement of placing the motor up near or into the inside concave portion of a convex dome or inverted convex cone diaphragm. In some preferred embodiments the low profile structure is facilitated by an inverted placement of the spider suspension above the plane of the surround suspension to stabilize the voice coil during excursion while supporting a low profile structure. Additionally, in numerous embodiments a coupling structure is utilized between the voice coil former and the diaphragm to create a broad surface area connection to the diaphragm to create a stiffer structure and minimizing breakup modes and creating a more robust mechanical structure to withstand greater output capability.
