Abstract

a. Haut-parleur électrodynamique comprenant une membrane convexe 1 dont la périphérie externe 11 est reliée souplement à la pièce polaire 3 entourant la bobine mobile 7 au moyen d'une bague de suspension 9 et rigidement au mandrin 6 de la bobine. b. Il est caractérisé en ce qu'une partie interne annulaire 10 sensiblement médiane de la membrane est reliée rigidement à l'extrémité du mandrin à l'opposé de celle supportant la bobine afin de réaliser une double liaison rigide 10, Il du mandrin et de la membrane propre à éviter toute déformation de la membrane en fonctionnement. c. Haut-parleur pour les fréquences moyennes et aiguës.
