Abstract

L’invention concerne un haut-parleur comprenant un bâti recevant au moins une membrane (19), un ensemble de mise en vibration de la membrane par un champ magnétique (C20, C21) généré par au moins une bobine électrique (26) solidaire de la membrane (19), ladite bobine (26) étant mobile par rapport à un aimant fixe, caractérisé en ce qu’il comporte une membrane (19) plane, au moins deux paires ( 20, 21) d’aimants (22 à 25) positionnées en périphérie d’une bobine électrique (26) en spirale à plat fixée en périphérie de la membrane (19), la périphérie de la bobine (26) étant située entre deux aimants (22 à 25) constitutifs d’une paire (20, 21) d’aimants (22 à 25) parallèles l’un à l’autre avec leurs pôles (S, N) de même polarité en regard et en ce que le corps du bâti a un plan principal de symétrie coplanaire au plan principal (M) de la membrane (19). L’invention concerne également un meuble de restitution sonore équipé d’au moins un tel haut-parleur. Figure à publier avec l’abrégé : Fig. 3The invention relates to a loudspeaker comprising a frame receiving at least one membrane (19), an assembly for vibrating the membrane by a magnetic field (C20, C21) generated by at least one electric coil (26) secured to the membrane (19), said coil (26) being movable relative to a fixed magnet, characterized in that it comprises a flat membrane (19), at least two pairs (20, 21) of magnets (22 to 25) positioned on the periphery of a flat spiral electric coil (26) fixed on the periphery of the membrane (19), the periphery of the coil (26) being located between two magnets (22 to 25) constituting a pair (20, 21) of magnets (22 to 25) parallel to each other with their poles (S, N) of the same polarity facing each other and in that the body of the frame has a main plane of symmetry coplanar with the plane main (M) of the membrane (19). The invention also relates to a sound reproduction cabinet equipped with at least one such loudspeaker. Figure to be published with the abstract: Fig. 3
