Abstract

L'invention concerne une suspension pour un micro-haut-parleur multifonctionnel comportant des arêtes, ainsi qu'un micro-haut-parleur multifonctionnel mettant en oeuvre cette suspension. Dans cette suspension, au moins une arête est formée sur le périmètre externe d'un matériau en feuille de forme prédéterminée, de sorte que les vibrations d'un vibrateur fixé sur le centre du matériau en feuille soient limitées structurellement dans un sens allant principalement du haut vers le bas. En outre, la déformation du matériau en feuille est empêchée, et le rayon (R) de la/des arête(s) ainsi que l'épaisseur (t) du matériau en feuille sont modifiés de sorte à permettre la régulation du déplacement vibratoire et de la fréquence de résonance. La/les arête(s) comporte(nt) des trous de passage d'air et, lorsqu'il existe une pluralité d'arêtes, les rayons des arêtes sont soit identiques soit différents.
