Title (EN) LOW COST MOTOR DESIGN FOR RARE-EARTH-MAGNET LOUDSPEAKERS
(FR) CONCEPTION ECONOMIQUE DE MOTEUR POUR HAUT-PARLEURS POURVUS D'AIMANTS A BASE DE TERRES RARES
Abstract: front page image
(EN)A loudspeaker magnetic motor utilizes a voice coil (20') with two or more wire coils that are connected in parallel and that are layered on top of one another. The motor utilizes, as a magnetic field source, a permanent magnet (12') and, more particularly, a permanent magnet that includes a rare earth metal such as a neodymium boron iron magnet.
(FR)La présente invention concerne un moteur magnétique de haut-parleur utilisant une bobine mobile (20') et deux enroulements ou plus superposés et reliés en parallèle. Ce moteur utilise comme source de champ magnétique un aimant permanent (12') et, plus particulièrement, un aimant permanent contenant un métal à base de terres rares, comme par exemple, un aimant à base de néodyme-bore-fer.
