Abstract
The present invention relates to a loudspeaker which can be arranged to minimise its overall depth while also increasing the breakup frequency and reducing potential rocking vibrations. Accordingly, the present invention is directed to a loudspeaker, comprising a magnet structure, and a voice coil lying within a magnetic field established by the magnet structure and responsive to electrical signals to undergo excursions from a rest position along an axis of motion; a driven body, connected to the voice coil and moveable to project acoustic waves from a front of the loudspeaker; and a suspension for providing a restoring force to the driven body towards the rest position, the suspension extending from an attachment point on the driven body to an attachment point on a fixed portion of the loudspeaker; wherein the driven body comprises a diaphragm and a support structure extending rearwardly from a connection point with the voice coil to a connection point with the suspension located rearward of the frontal part of the magnet structure.
