Abstract

TITRE DE L’INVENTION : HAUT-PARLEUR À GRANDE EXCURSION, FAIBLE DISTORSION ET FAIBLE PROFONDEUR Le haut-parleur (60) comporte un aimant (40) associé à au moins une pièce polaire (39, 41) pour produire un champ magnétique dans un entrefer et un équipage mobile comportant :- une première carcasse de bobine (48) portant un bobinage conducteur (42) dans l’entrefer,- une première membrane rigide (47) et un cache-noyau (45) solidaires de la première carcasse,- une deuxième carcasse de bobine (49) positionnée à l’extérieur des pièces polaires et montée sur une suspension arrière (36),- une deuxième membrane (50) solidaire de la première membrane rigide, de la deuxième carcasse et d’une suspension avant (31) et- deux conducteurs électriques (33, 46) reliés au bobinage et parcourant la première carcasse de bobine, un chemin aérien entre les carcasses de bobine, la deuxième carcasse de bobine et un chemin aérien jusqu’à un point fixe (34) du haut-parleur. Figure pour l'abrégé : Figure 3TITLE OF THE INVENTION: HIGH EXCURSION, LOW DISTORTION, SHORT DEPTH LOUDSPEAKER The loudspeaker (60) includes a magnet (40) associated with at least one pole piece (39, 41) to produce a magnetic field in a air gap and a moving assembly comprising:- a first coil carcass (48) carrying a conductive winding (42) in the air gap,- a first rigid membrane (47) and a core cover (45) integral with the first carcass, - a second coil carcass (49) positioned outside the pole pieces and mounted on a rear suspension (36), - a second membrane (50) integral with the first rigid membrane, the second carcass and a suspension front (31) and- two electric conductors (33, 46) connected to the winding and traversing the first coil carcass, an aerial path between the coil carcasses, the second coil carcass and an aerial path up to a fixed point ( 34) of the loudspeaker.
