Abstract

Sistema acústico, en particular transductor acústico, con una carcasa (2), que rodea un volumen y en el que está formada al menos una superficie o una superficie parcial a través de una estructura superficial (1) alojada de forma apta para oscilación, en el que en el volumen está presente polvo (3) de material adsorbente con superficie activa para adsorción, en el que el polvo (3) está seleccionado de tal forma que a través de oscilaciones de la estructura superficial (1) alojada apta para oscilaciones en el volumen se realiza un movimiento del polvo (3) de tal manera que se incrementa la superficie activa para adsorción, en el que el material adsorbente está seleccionado de tal manera que en el caso de una elevación de la presión a través de oscilaciones de la estructura superficial (1) alojada apta para oscilaciones se lleva a cabo una adsorción de aire o gas que se encuentra en el volumen, caracterizado porque el polvo (3) es móvil libremente en toda la carcasa (2).
