摘要： Apparatus and methods for a velocity-sensing approach to loudspeaker motional feedback comprising providing a first magnetic field to couple primarily with the voice coil to drive the voice coil, providing a second magnetic field to couple primarily with the sensing winding, and sensing the voltage induced in the second, sensing winding as it reciprocates in the second magnetic field. The second magnetic field has an orientational periodicity which is circumferential in relation to the reciprocation axis and this orientational periodicity extends over at least a part of the length of the former along the reciprocation axis.
