Abstract: An apparatus includes a load and a first armature. A first lever mechanically couples the first armature and the load. Motion of the first armature causes the first lever to pivot about a first pivot axis. The apparatus also includes a second armature and a second lever that mechanically couples the second armature and the load. Motion of the second armature causes the second lever to pivot about a second pivot axis. At least one stator is provided for creating magnetic flux for the first and second armatures to interact with, thereby to drive motion of the load. The apparatus also includes a coupling mechanism that couples the first lever and the second lever. The coupling mechanism is arranged to encourage common mode oscillation of the first and second levers and inhibit differential mode oscillation of the first and second levers, thereby to inhibit rocking of the load.

Abstract: An electro-acoustic driver including an acoustic waveguide includes an enclosure, an acoustic transmission line formed within the enclosure, and a plurality of acoustic transducers contained within the enclosure and disposed along a length of the acoustic transmission line. Each acoustic transducer is configured to emit acoustic energy directly into the acoustic transmission line at two separated locations along the length of the acoustic transmission line.

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.

Abstract: An apparatus includes a load, a lever that is coupled to the load, and an electric motor that is coupled to the lever for driving the lever in oscillatory, rotary motion about a pivot axis. The electric motor includes an armature and a stator. The armature is coupled to the lever and includes a permanent magnet. The stator defines an air gap within which the armature is disposed. The stator is configured for creating magnetic flux across the air gap for the permanent magnet to interact with, thereby to drive motion of the load. The electric motor is configured such that substantially no detent forces (a/k/a cogging forces) are generated between the stator and the permanent magnet as the lever is driven by the motor.
