Abstract

Le haut-parleur (100) comporte un boîtier (110), un moteur (111) avec un noyau magnétique (112) et une bobine d'induction (113) solidaire d'une première plaque rigide (114) de transmission de vibrations à un support (300) qui est solidaire du boîtier (110) par une seconde plaque (115) de suspension et de positionnement radial de la bobine (113) et des patins élastiques (116) qui assurent une suspension élastique de la première plaque rigide (114) au boîtier (110).The loudspeaker (100) includes a housing (110), a motor (111) with a magnetic core (112) and an induction coil (113) integral with a first rigid vibration transmission plate (114) at a support (300) which is secured to the housing (110) by a second radial suspension and positioning plate (115) of the coil (113) and resilient pads (116) which provide an elastic suspension of the first rigid plate ( 114) to the housing (110).
