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. 3
