Abstract

Un transducteur audio comprend un diaphragme, une structure de base de transducteur et un système de suspension de diaphragme. Le système de suspension de diaphragme comporte au moins une articulation à charnière de contact couplant le diaphragme à la structure de base de transducteur pour assurer un mouvement de rotation du diaphragme par rapport à la structure de base de transducteur autour d'un axe de rotation. Un mécanisme de transduction couple de manière fonctionnelle le diaphragme pour effectuer une transduction entre des signaux audio électriques et une pression sonore. Dans un mode de réalisation, chaque articulation à charnière de contact comprend jusqu'à quatre interfaces de contact, chaque interface de contact possédant deux surfaces de contact mobiles les unes par rapport aux autres. D'autres modes de réalisation de systèmes de suspension de diaphragme, de structures de diaphragme, de mécanismes de transduction et de dispositifs audio les incorporant sont divulgués.
