Abstract

L'invention concerne un diaphragme de haut-parleur en graphène, comprenant une couche de substrat de diaphragme (12) et une couche de graphène (11) adhérant à une surface de la couche de substrat de diaphragme (12). En fournissant une exigence de satisfaction de conception de diaphragme d'un haut-parleur miniature et étant particulièrement utile pour un diaphragme de vibration de haut-parleur d'un écouteur, la présente invention permet un cintrage à grand angle tout en empêchant une déformation irréversible, fournit une endurance supérieure à une pression élevée, et améliore la résistance de la membrane, améliorant ainsi les performances de sortie acoustique d'un haut-parleur.
