Title (EN) MULTIPLE ACTIVE COIL SPEAKER
(FR) HAUT-PARLEUR A BOBINE MULTI-ACTIF
Abstract: front page image
(EN)A voice tube assembly for a loudspeaker (20), comprising a basket (36), a cone (25), and a spider (34) includes a first magnet (47). The first magnet is configured for attachment onto the basket and has a principle axis. A second magnet (49) is coaxially configured with the first magnet and spaced apart from it. A voice tube (26) of non-ferrous material includes a cylindrical sleeve having a first extremity, a second extremity, and a cylinder axis. The cylinder axis is arranged to coincide with the principle axis. A first voice coil (46) of conductive wire is wrapped around the first extremity in operational proximity to the first magnet. A second voice coil (48) of conductive wire is wrapped around the second extremity in operational proximity to the second magnet.
(FR)L'invention concerne un ensemble tube acoustique d'un haut-parleur (20) comprenant un panier (36), un cône (25), et une suspension, qui comporte un premier aimant (47). Ledit premier aimant est destiné à se fixer au panier (36) et possède un axe principal. Un second aimant (49), coaxial avec le premier aimant, est à distance de celui-ci. Un tube acoustique (26) en matériau non ferreux comporte un manchon cylindrique ayant une première extrémité, une seconde extrémité et un axe cylindrique. Ledit axe cylindrique est disposé de manière à coïncider avec l'axe principal. Une première bobine mobile (46) en fil conducteur est enroulée autour de la première extrémité à proximité fonctionnelle du premier aimant (47). Une seconde bobine mobile (48) en fil conducteur est enroulée autour de la seconde extrémité à proximité fonctionnelle du second aimant (49).
