Abstract: A loudspeaker includes an acoustic diaphragm, a lever, and an oscillatory force source for driving the lever in oscillatory, rotary motion about a pivot axis. The loudspeaker also includes a connector that couples the lever to the acoustic diaphragm. The connector includes a first rotary joint that defines a first rotary axis that is fixedly attached to the acoustic diaphragm, a second rotary joint that defines a second rotary axis that is fixedly attached to the lever, and a linkage coupling the first and second rotary joints. The connector allows for rotational and translational movement of the lever and the diaphragm relative to each other.

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.
