Abstract:
(EN) A head-mounted display (HMD) includes a housing defining an enclosure having an aperture. A is speaker positioned within the enclosure, the speaker having a back side facing an interior surface of the housing and a front side facing away from the interior surface of the housing, a back volume defined between at least a portion of the housing and the back side of the speaker for enhancing sound generated by the speaker. A sound conduit having an end open to the enclosure and extends outside the housing through the aperture. The sound conduit has another end open toward a rear direction to transmit the sound generated by the speaker.
(FR) L'invention concerne un visiocasque (HMD) comprenant un boîtier définissant une enceinte ayant une ouverture. A est un haut-parleur positionné à l'intérieur de l'enceinte, le haut-parleur ayant un côté arrière faisant face à une surface intérieure du boîtier et un côté avant faisant face à la surface intérieure du boîtier, un volume arrière défini entre au moins une partie du boîtier et le côté arrière du haut-parleur pour améliorer le son généré par le haut-parleur. Un conduit sonore ayant une extrémité ouverte vers l'enceinte et s'étend à l'extérieur du boîtier à travers l'ouverture. Le conduit sonore a une autre extrémité ouverte vers une direction arrière pour transmettre le son généré par le haut-parleur.
