Abstract

L'invention concerne un haut-parleur qui comporte un saladier (2) cupuliforme, un corps magnétique (3) s'étendant à l'intérieur du saladier (2) et monté coaxialement par rapport à un axe longitudinal (A) de ce dernier, une membrane (4) de forme sensiblement tronconique montée dans l'axe du corps magnétique (3) et coulissant par rapport à celui-ci et une bobine de commande (8) montée dans l'axe du corps magnétique (3), coulissant par rapport à celui-ci et intégrée à la membrane (4). Le haut-parleur (1) comporte également une première membrane d'amortissement (14) et de centrage annulaire reliant le corps magnétique (3) à la membrane (4) et une seconde membrane d'amortissement (17) et de centrage annulaire reliant la bobine (8) à la paroi latérale (18) du saladier (2).
