Abstract
A loudspeaker includes an acoustic diaphragm, an oscillatory force source, a lever that couples the oscillatory force source to the acoustic diaphragm, and a pivot that is coupled to the lever such that the lever pivots about a pivot axis when the oscillatory force source applies a force to the lever. The pivot includes a pair of rotational joints which are spaced apart to allow the diaphragm to pass therebetween as the lever pivots about the pivot axis.
