Abstract
An electronic linear motor particularly for use with loudspeakers includes first and second annular counterfacing air gaps centered on a motor axis. An armature and spider carry first and second voice coils in the first and second annular air gaps, respectively. A rigid link connects the armature and an output device, such as a loudspeaker cone. A releasable coupling attaches either or both ends of the rigid link to an adjacent armature or output device.
