Abstract

L'invention concerne un élément acoustique comprenant un nombre arbitraire de couches. Chaque couche comporte au moins une couche poreuse (2) et un film (4) placé à une certaine distance de la couche. La couche poreuse (2) peut être électriquement conductrice ou revêtue sur au moins une de ses surfaces de façon à être électriquement conductrice, le film (4) pouvant être chargé ou pourvu d'au moins une surface électriquement conductrice. La couche poreuse (2) et le film (4) n'entrent en contact qu'au niveau de points de support (5). Ces points de support (5) sont conçus de manière à permettre à toute la structure de changer d'épaisseur.
