Abstract: front page image
(EN)The invention relates to a loudspeaker, which contains bearing structure, a magnetic arrangement (12) fixed to the bearing structure, determining air-gaps (13), and a diaphragm connected to the bearing structure, made of a sheet material. The diaphragm has the shape of a cylindrical jacket consisting of segments (10), the segments (10) are connected to each other along delimiting lines running in the direction of the generating lines, and they have a surface the curvature of which is larger than the curvature that belongs to the overall radius of the cylindrical jacket-like shape, there is a flap (11) at least along two delimiting lines, which flaps (11) extend into an air-gap (13) each radially, and the diaphragm is connected to the bearing structure with flexible supporting units joining the flaps (11) and allowing radial movement of the flaps (11) in the air-gap (13).
(FR)L’invention concerne un haut-parleur qui comprend une structure d'appui, un agencement magnétique (12), fixé à la structure d'appui, définissant des entrefers (30), et une membrane raccordée à la structure d'appui conçue dans un matériau en feuille. La membrane a la forme d’une chemise cylindrique composée de segments (10), ces segments (10) étant raccordés entre eux le long de lignes de délimitation s’étendant dans le sens des lignes de formation, et présentant une surface de courbure plus importante que la courbure du rayon global de la chemise cylindrique, un rabat (11) étant formé au moins le long de deux lignes de délimitation, lesquels rabats (11) s’étendent chacun radialement dans un entrefer (13), et la membrane est raccordée à la structure d'appui par des unités de support flexibles reliant les rabats (11) et permettant leur déplacement radial dans l’entrefer (13).
