Title (EN) LOUDSPEAKER MOTOR AND SUSPENSION SYSTEM
(FR) SYSTÈME DE SUSPENSION ET MOTEUR DE HAUT-PARLEUR
Abstract: front page image
(EN)A loudspeaker includes a voice coil in a balanced state. In the loudspeaker, at least a first suspension element acts on a first side of the voice coil, and at least a second suspension element acts on a second side of the voice coil. The loudspeaker includes a symmetric magnet assembly. The voice coil aligns with the symmetric magnet assembly. The symmetric alignment contributes to the loudspeaker yielding substantially symmetric motor force (BL), suspension stiffness (K), and inductance (Le).
(FR)La présente invention concerne un haut-parleur comprenant une bobine mobile dans un état équilibré. Dans le haut parleur, au moins un premier élément de suspension agit sur un premier côté de la bobine mobile, et au moins un second élément de suspension agit sur un second côté de la bobine mobile. Le haut-parleur comprend un ensemble d'aimants symétriques. La bobine mobile s'aligne avec l'ensemble d'aimants symétriques. L'alignement symétrique offre au haut-parleur une force de moteur symétrique considérable (BL), une rigidité de suspension (K), et une inductance (Le).
