Abstract

Les modes de réalisation de la présente divulgation concernent un dispositif monté sur la tête VR, comprenant une unité principale de dispositif montée sur la tête et une structure de port reliée à l'unité principale de dispositif monté sur la tête. Un ensemble de production de son est disposé sur la structure de port, l'ensemble de production de son comprenant un corps utilisé pour produire un son et un boîtier relié au corps. Une cavité sonore est définie par le boîtier et le corps, et la cavité sonore a un trou de sortie de son, de telle sorte qu'un son peut être transmis à l'environnement externe à travers le trou de sortie de son, le trou de sortie de son faisant face à la partie inférieure ou à la partie arrière du dispositif monté sur la tête VR. Lorsqu'un utilisateur porte le dispositif monté sur la tête VR, le trou de sortie de son de la cavité sonore doit seulement faire face à l'oreille de l'utilisateur ou être proche de celle-ci, et l'ensemble de production de son n'a pas besoin d'être en contact direct avec l'oreille de l'utilisateur, ce qui permet d'améliorer le confort de port du dispositif monté sur la tête VR. En outre, lorsque le son est transmis vers l'extérieur à travers le trou de sortie de son de la cavité sonore de l'ensemble de production de son, et l'ensemble de production de son est disposé sur la structure de port, la distance entre l'ensemble de production de son et l'oreille de l'utilisateur est petite, garantissant ainsi un bon effet acoustique.
