Abstract
A loudspeaker enclosure defined by one or more panels housing a drive unit. The drive unit includes a coil, a diaphragm, and a magnet. The magnet is decoupled from the one or more panels of the loudspeaker enclosure. Sound is generated by the movement of the diaphragm and complementary movement of the magnet, on application of an appropriate electrical signal to the coil. The moving diaphragm acts against a first volume of air within the enclosure, while the movement of a surface coupled to the magnet, acts against a second air volume, different from the first volume. The surface coupled to the magnet is decoupled from the one or more panels of the loudspeaker enclosure.
