Abstract
A loudspeaker and method of operating a loudspeaker are provided. The loudspeaker has a motor assembly with at least one planar coil. First and second magnets are magnetized in a magnetized direction perpendicular to a direction of coil movement and perpendicular to a central axis of radiation of the loudspeaker. The central axis of radiation is generally parallel to a direction of coil movement and parallel to the plane of the planar coil. The first and second magnets each have upper and lower large surface faces separated by a narrowest dimension. The first and second magnets are magnetized across the narrowest dimension in first and second magnetized directions being opposite.
