Abstract
The present invention provides a loudspeaker with at least two diaphragm assemblies, in which the reactive forces acting on the magnets in each assembly cancel. By linking the two magnets together via a non-rigid material, resonance in the drive assemblies is highly damped and corresponding distortion of the loudspeaker output is reduced.
Claims18
A loudspeaker, comprising:
- a first diaphragm and a respective first drive assembly, the first drive assembly comprising at least a first magnet;
- a second diaphragm and a respective second drive assembly, the second drive assembly comprising at least a second magnet;
- and
- a coupling member connecting the first magnet to the second magnet, said coupling member comprising a non-rigid material arranged such that forces are conveyed from the first magnet to the second magnet and vice versa, but that vibrations in the coupling member are damped.
