Title (EN) STIFFENING PLATE FOR ACOUSTIC MEMBRANE AND METHOD OF MANUFACTURING SAME
(FR) PLAQUE DE RENFORT POUR MEMBRANE ACOUSTIQUE ET SON PROCÉDÉ DE FABRICATION
Abstract: front page image
(EN)A method of thinning a multilayer laminate material is provided to obtain a membrane stiffening plate (14) having a thickness less than currently known in the art. The multilayer laminate material comprises a middle layer (20) and two outer metal layers (16,18) that have been compressed without being subjected to heat. The method provides for a significant reduction in the thickness of a membrane stiffening plate and provides for a mechanism to tune the cut-off frequency of a loudspeaker on which the membrane stiffening plate is used.
(FR)L'invention concerne un procédé d'amincissement d'un matériau stratifié multicouche destiné à permettre l'obtention d'une plaque de renfort (14) de membrane présentant une épaisseur inférieure à celle de l'état actuel de la technique. Le matériau stratifié multicouche comprend une couche centrale (20) et deux couches métalliques externes (16, 18) qui ont été comprimées sans avoir été soumises à la chaleur. Le procédé permet d'obtenir une réduction significative de l'épaisseur d'une plaque de renfort de membrane ainsi qu'un mécanisme permettant d'accorder la fréquence de coupure d'un haut-parleur sur lequel est utilisé la plaque de renfort de membrane.
