Abstract

Haut-parleur à faible inertie La présente invention concerne (10) comportant une structure porteuse (12), une membrane de diffusion (14) mobile par rapport à la structure porteuse (12) et un moteur (16) d’actionnement de la membrane de diffusion (14) comportant un équipage mobile (18) déplaçable par rapport à la structure porteuse (12), l’équipage mobile (18) étant relié mécaniquement à la membrane de diffusion (14) pour leur déplacement synchronisé. Il comporte un circuit hydraulique (20, 22) interposé entre l’équipage mobile (18) et la membrane (14), la membrane (14) et l’équipage mobile (18) comportant chacun une surface de piston mobile, en interaction avec un fluide (22) du circuit hydraulique (20, 22).
