Abstract

Est divulgué un dispositif d'affichage monté sur le visage. Une branche du dispositif d'affichage monté sur le visage comprend : une partie de réception de haut-parleur formée pour recevoir un haut-parleur au niveau de l'extrémité arrière de celle-ci ; et des trous de haut-parleur espacés par des distances prédéfinies à partir de la partie de réception de haut-parleur et situés devant les oreilles d'un utilisateur. La partie de réception de haut-parleur et les trous de haut-parleur sont connectés en communication l'un avec l'autre. Par conséquent, la taille de la branche est réduite, et l'utilisateur peut entendre clairement le son provenant du haut-parleur.
