Abstract

Las cavidades vacías (1) que generalmente se encuentran en las guanteras, puertas y otras partes de los automoviles se utilizan para contenercompartimientos de volumenes cerrados de aire para los parlantes activos (6) combinados con respectivas membranas pasivas calibradas (7). Los sistemasacusticos que se obtienen recrean dentro de las cavidades (1) disponibles en los automoviles, las mismas situaciones de incremento de la eficacia de losparlantes a bajas frecuencias, siendo sus dimensiones iguales, como las obtenidas al adoptar compartimientos ya pre-disenados en los cuales los elementospasivos, ubicados sobre amortiguadores, funcionan de acuerdo con dichos parlantes y explotan los mismos volumenes cerrados de aire que se logran en aquelloscompartimientos.The empty cavities (1) that are generally found in the glove boxes, doors and other parts of the cars are used to contain compartments of closed air volumes for the active speakers (6) combined with respective passive calibrated membranes (7). The acoustic systems that are obtained recreate within the cavities (1) available in cars, the same situations of increasing the efficiency of speakers at low frequencies, their dimensions being the same, as those obtained by adopting pre-designed compartments in which passive elements, located on dampers, operate in accordance with said speakers and exploit the same closed volumes of air that are achieved in those compartments.
