<p>The present invention provides a loudspeaker comprising a diaphragm (1), a surround (2) attached to the periphery of the diaphragm (1), two voice coils (7) attached to the underside of the diaphragm (1) and suspended within corresponding magnetic motors, and a frame (3) that all components are attached to. There is no other suspension element in this design, maximizing the excursion capability of the diaphragm to be the clearance between the diaphragm and the motors. With the above structure, the overall depth of the loudspeaker can be below 13mm and the operating bandwidth of the loudspeaker extend s below 400 Hz.</p> |
