Abstract (en)

[origin: EP1052879A2] The flat element has a plate-shaped component (1) and at least one transducer (2) on the component that is driven by an electrical audio signal to stimulate the component to vibrate flexurally at its natural resonant frequency to form an acoustic multimode resonance radiator. The flat element has a clamping device (3) connected to the component and that holds the component under tension. An Independent claim is also included for a cover element.
