Abstract
A panel loudspeaker comprising a panel, at least one driver, and a frame connected to the panel. The panel has a plurality of edges and is capable of sustaining bending waves. The driver is connected to the panel at a location that is neither at or near the edges of the panel, nor at or near the center of the panel, to vibrate the panel to cause it to resonate and produce an acoustic output. The driver location is in a positioning area that lies between a center-of-gravity area, which is centered on the center of gravity of the panel, and an edge area, which abuts the edges of the panel.
