Abstract

Un dispositif, qui permet d'améliorer des effes sonores, comporte plusieurs éléments plats (2, 3) réalisés en métal ou en bois et séparés par une pièce intermédiaire (4). La périphérie de cette dernière, dont le diamètre est inférieur à celui des éléments plats (2, 3), forme une gorge (5) circulaire, et on trouve au moins sur la surface libre des éléments plats (2, 3) plusieurs sillons horizontaux (7) radiaux disposés à intervalles réguliers. De plus, la périphérie des éléments plats (2, 3) est chanfreinée. On peut avec ce dispositif mieux ressentir les vibrations puissantes produites par un appareil électrique de diffusion sonore, vibrations qui se transforment en un son clair.
