Abstract:
A loudspeaker device comprises first and second diaphragms (12, 14) arranged co-axially in an opposed relation to each other to cancel mechanical vibrations. Each diaphragm has multiple voice coils, with the voice coils of the first and second diaphragms (12, 14) arranged in the same plane to reduce the height of the loudspeaker device.
