Abstract: An acoustic device with an enclosure and a first passive radiator structure which includes a first passive radiator diaphragm. The first passive radiator structure has an effective radiating area and a first mass, and is mounted to the enclosure such that its diaphragm can vibrate relative to the enclosure. There is a second passive radiator structure which includes a second passive radiator diaphragm. The second passive radiator structure has substantially the same effective radiating area as the first passive radiator structure, and is mounted to the enclosure such that its diaphragm can vibrate relative to the enclosure. At least one active electro-acoustic transducer is mounted to the second passive radiator structure such that it moves when the diaphragm vibrates. The second passive radiator structure and the active transducer together have a second mass that is substantially greater than the mass of the first passive radiator structure. Passive radiators with the same effective radiating area results in force balancing of the device.

Abstract: A loudspeaker includes an acoustic diaphragm, an oscillatory force source, a lever coupling the oscillatory force source to the acoustic diaphragm, and a pivot coupled to the lever such that the lever moves in an arcuate path about the pivot when the oscillatory force source applies a force to the lever. The pivot includes at least one torsion bushing. The at least one torsion bushing includes a first member, a second member coupled to the lever and movable relative to the first member, and an elastomeric member coupling the first member to the second member. Either the first member or the second member is coupled to and moves with the lever. An outer surface of the elastomeric member is coupled to the second member via mechanical compression.
