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.From one aspect of the present, an acoustic device is provided, eg, a loudspeaker comprising a resonant multimode acoustic radiation screen that has opposite faces, a vibration exciter designed to generate bending wave vibrations to the resonant screen to produce a acoustic output means defining a cavity that contains at least a part of a face of the screen and arranged to contain the acoustic radiation of said part of the face of the screen, the cavity being such that it modifies the modal behavior of the screen. Another aspect of the present is provided for a method to modify the modal behavior of a resonant acoustic screen device, which comprises arranging the resonant screen very close to a perimeter surface to define a resonant cavity between them.
