Rigid linear diaphragm loudspeaker and mounting system

Abstract

A frame has an elongate form with elongate rest shelves on lateral sides thereof to support ceiling tiles. Ends of the frame are connected to T-bars within a suspended ceiling, as one example of mounting system for the loudspeaker of this invention. A yoke is fixed within a channel of the frame. The yoke has a pair of arms supporting magnets on ends thereof. A gap is provided between the magnets. A voice strip is located within this gap between the magnets and has a piston thereon which includes a diaphragm. A voice coil associated with the voice strip interacts with a magnetic field created by the magnets to cause the piston to vibrate, and in turn to cause the diagram to emit sound waves. The diaphragm is elongate with a width less than 10% of its length. A surround supports a perimeter of the diaphragm relative to the frame.
