Abstract

Dispositif d'enceinte acoustique aux performances accrues au moyen d'un boîtier et d'éléments intérieurs recouverts par un gel souple absorbant les vibrations et variations de pression. Le dispositif selon l’invention est composé d'un caisson solide recouvert d'un gel de dureté minimale. Le gel absorbe les différentes vibrations et variations de pression qui ne peuvent pas être absorbés par les isolants acoustiques actuels. La masse des parois et éléments de l'enceinte est accrue sans pour autant accroître la rigidité de ceux-ci. L'enceinte acoustique peut comporter les isolants acoustiques classiques en plus du gel. De nombreuses caractéristiques du gel de l'enceinte, de sa forme et de sa composition peuvent être adaptées, le meilleur compromis peut être trouvé.Loudspeaker device with increased performance by means of a casing and interior elements covered with a flexible gel that absorbs vibrations and pressure variations. The device according to the invention is composed of a solid box covered with a gel of minimum hardness. The gel absorbs the various vibrations and pressure variations that cannot be absorbed by current acoustic insulation. The mass of the walls and elements of the enclosure is increased without thereby increasing their rigidity. The acoustic enclosure may include conventional acoustic insulators in addition to gel. Many characteristics of the enclosure gel, its shape and its composition can be adapted, the best compromise can be found.
