PROBLEM TO BE SOLVED: To provide a speaker system which reduces distortion caused by modulation of a magnetic field within an air gap in a driver assembly as well as reduces eddy currents.SOLUTION: The loudspeaker system comprises a motor assembly for driving a diaphragm assembly, where the motor assembly includes a pole piece configured to receive an inductance sleeve. The motor assembly also comprises a permanent magnet, a first shorting ring, and a second shorting ring. The first and second shorting rings are positioned at least partially within an air gap adjacent to the pole piece. In addition, the first shorting ring is positioned adjacently to a first side of the permanent magnet, and the second shorting ring is positioned adjacently to a second side of the permanent magnet. The permanent magnet is preferably coated with an insulating material and comprises a plurality of arcuate segments. |
