  • Acoustic system having a housing with adsorbent powder
    Patent number: 10178468
    Abstract: An acoustic system is provided that includes a transducer having a housing, which encloses a volume and in which at least a surface or a sub-surface is formed by a sheet-like structure configured to vibrate. Powder made of adsorbent material having an adsorption effective surface may be present in the volume. The powder may be selected such that, through a movement of the powder caused by vibrations of the sheet-like structure configured to vibrate, the adsorption effective surface is enlarged. The adsorbent material may be selected such that an adsorption of air or gas present in the volume is caused by an increase of the pressure caused from vibrations of the sheet-like structure configured to vibrate. The powder is freely movable within the housing.
