Abstract
Moteur de Haut-parleur à deux aimants opposés Le haut-parleur (1) comprend un circuit magnétique (4). Le haut-parleur (1) comprend un équipage mobile (5) déplaçable par rapport au circuit magnétique (4). Le porte bobine (30) est monté mobile au travers d’entrefers (77, 86) et un élément (105) de guidage de l’équipage mobile (5) est disposé entre l’équipage mobile (5) et un châssis (3), du côté d’une membrane (35) par rapport au circuit magnétique (4). L’équipage mobile (5) traverse de part en part le circuit magnétique (4) au travers d’entrefers (86, 87) d’extrémité. Le haut-parleur (1) comporte un élément de guidage complémentaire (110), disposé entre l’équipage mobile (5) et le châssis (3), du côté opposé à la membrane (35) par rapport au circuit magnétique (4).
