REDUCED DISTORTION LOUDSPEAKERS

摘要

A loudspeaker including a pole piece and a magnetic assembly with a voice coil located in an air gap therebetween. The pole piece contains high concentration of AC energy, both as magnetic flux and as eddy currents. The pole piece and the magnetic assembly are configured in two or more electrically isolated sections which interrupt the electric connection between the pole piece and a magnetically permeable bottom plate, thereby decreasing the electric conduction of pole piece eddy currents in the bottom plate, resulting in a reduction in the distortion.
