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.

摘要： An acoustic insert (6) for lining a loudspeaker reflex port (4), the insert (6) comprising an elongate hollow tube formed of a flexible material, having an outer wall sized and configured to seat within the port (4) and an inner wall extending in the elongate direction, the inner wall having a circumference which varies along the length of the insert. When inserted in a port (4), the insert (6) alters the port resonance so as to vary the acoustic performance of the loudspeaker.
