LOW PROFILE LOUDSPEAKER TRANSDUCER

摘要

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.

主权项

1. A low profile loudspeaker transducer, comprising:
a magnet; a top plate disposed above the magnet; a voice coil former having a first end which terminates above the top plate; a diaphragm extending over the top plate; a coupler connecting the diaphragm to the first end of the voice coil former; a first suspension disposed beneath the diaphragm and affixed at one end to the diaphragm and at a second end to the top plate; and a second suspension extending from an outer edge of the diaphragm to a frame of the loudspeaker transducer.
