Inverted dual coil transducer

摘要

A dual coil transducer is provided that has a low profile construction. The transducer includes a voice coil disposed around a central region of the transducer, a diaphragm with flexible suspension extending generally outwardly from the central region and including an inner edge attached to the voice coil, where the diaphragm includes a concave surface, and at least one magnet assembly disposed forward of the concave surface, where the at least one magnet assembly defines at least two magnetic gaps disposed about the central region. The transducer will usually be mounted with the motor outside of the loudspeaker enclosure for best heat dissipation.
