Abstract

Haut-parleur comprenant au moins une membrane et un organe de suspension assurant le rôle de plusieurs éléments de guidage La présente invention concerne un haut-parleur (10) comprenant un châssis (15), et au moins une membrane (27) adaptée pour vibrer par rapport au châssis (15) selon un axe (D) du haut-parleur (10) et émettre des ondes sonores. La ou chaque membrane (27) s’étend radialement par rapport à l’axe (D) du haut-parleur (10). La ou chaque membrane (27) a un bord radialement extérieur. Le haut-parleur (10) comprend en outre un organe de suspension (35) d’une seule pièce, formant une pluralité d’éléments de guidage (55, 60 ; 60, 62 ; 55, 60, 62) de la membrane (27), ou de la membrane (27) et d’au moins une autre membrane (26). Figure pour l'abrégé : Figure 1Loudspeaker comprising at least one membrane and a suspension member providing the role of several guide elements The present invention relates to a loudspeaker (10) comprising a chassis (15), and at least one membrane (27) adapted to vibrate relative to the chassis (15) along an axis (D) of the speaker (10) and emit sound waves. The or each membrane (27) extends radially relative to the axis (D) of the loudspeaker (10). The or each membrane (27) has a radially outer edge. The loudspeaker (10) further comprises a suspension member (35) in one piece, forming a plurality of guide elements (55, 60; 60, 62; 55, 60, 62) of the membrane ( 27), or the membrane (27) and at least one other membrane (26).
