Abstract
De un aspecto de la presente se prevee un dispositivo acustico, por ej., un altavoz que comprende una pantalla de radiacion acustica multimodo resonanteque tiene caras opuestas, un excitador de vibracion disenado para generar vibraciones de onda de curvado a la pantalla resonante para producir una salidaacustica medios que definen una cavidad que contiene al menos una parte de una cara de la pantalla y dispuestos para contener la radiacion acustica de dichaparte de la cara de la pantalla, siendola cavidad tal que modifica el comportamiento modal de la pantalla. De otro aspecto de la presente se prevee un métodopara modificar el comportamiento modal de un dispositivo acustico de pantalla resonante, que comprende disponer la pantalla resonante muy cerca de unasuperficie perimetral para definir una cavidad resonante entre las mismas.
