摘要： A loudspeaker including a moving magnet motor. The moving magnet motor includes an armature comprising a magnet carrier, and a lever arm, coupling the armature and a pivot. The lever arm further couples the armature and an acoustic diaphragm to transmit motion of the armature to the acoustic diaphragm to cause the acoustic diaphragm to move. The loudspeaker described may be torque balance and moment balanced.

摘要： An apparatus includes at least one load and a plurality of armatures, each including a permanent magnet, which are coupled to the at least one load to cause the at least one load to move. The apparatus also includes a common stator that defines an air gap within which the plurality of armatures is disposed. The common stator is configured for creating magnetic flux across the air gap for the armatures to interact with, thereby to drive motion of the at least one load.
