ABSTRACT:
A system for radiating sound from a movable member, with a speaker which includes a loudspeaker with a longitudinally movable speaker coil, a flat glass plate spaced from the speaker coil, and a rigid mechanical member connected between the speaker coil and the flat plate to transfer longitudinal motion of the speaker coil to the flat plate, to cause movement of the flat plate. There is also a speaker mount for acoustically and mechanically coupling the flat plate to a window to efficiently transfer plate movements to the window for causing the window to directly radiate sound as a result of speaker coil motion.
