Title
(EN) MEMBRANE PLATE STRUCTURE FOR GENERATING SOUND WAVES
(FR) STRUCTURE DE PLAQUE À MEMBRANE PERMETTANT LA GÉNÉRATION D'ONDES SONORES
Abstract
(EN)
The present invention relates to a membrane plate structure for generating sound waves, the membrane plate structure comprises a vibrating element for generating sound waves and a membrane plate which is coupleable to the vibrating element. The membrane plate has a different width with respect to its length, wherein the width is shorter than the length. The membrane plate comprises an UD layer made of fibers, wherein the fibers of the UD layer are oriented along the width of the membrane plate.
(FR)
La présente invention concerne une structure de plaque à membrane permettant la génération d'ondes sonores, la structure de plaque à membrane comprenant un élément vibrant destiné à la génération d'ondes sonores et une plaque à membrane pouvant être couplée à l'élément vibrant. La plaque à membrane présente une largeur différente de sa longueur, la largeur étant plus courte que la longueur. La plaque à membrane comprend une couche UD constituée de fibres, les fibres de la couche UD étant orientées le long de la largeur de la plaque à membrane.
