Title (EN) PLANAR MAGNETIC TRANSDUCER WITH DISTORTION COMPENSATING DIAPHRAGM
(FR) TRANSDUCTEUR MAGNETIQUE PLAN AVEC DIAPHRAGME COMPENSATEUR DE DISTORSION
Abstract: front page image
(EN)Diaphragms (38) of planar magnetic transducers (18) having electrical conductor runs (40) applied thereto are deformed to create lines of flexation (46) such as by knurling, pressing, embossing or the like prior to being placed under tension within a support frame (20) so as to reduce loss of diaphragm tension and thereby control resonance modes along active surface areas of the diaphragm when electrical energy is applied through the conductor runs.
(FR)On déforme les diaphragmes (38) de transducteurs magnétiques plans (18), sur lesquels sont posées des longueurs (40) de conducteurs électriques, de façon à créer des lignes de flexion (46), notamment par moletage, emboutissage, gaufrage, etc., avant de les mettre sous tension à l'intérieur d'un cadre support (20). Ce procédé permet de réduire la perte de tension des diaphragmes et ainsi de commander les modes de résonance le long des surfaces actives desdits diaphragmes quand une énergie électrique est appliquée aux longueurs de conducteurs.
