Abstract:
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.
