Abstract

L'invention concerne un dispositif que l'on utilise en qualité d'écouteurs rapportés qui peuvent être utilisés dans le domaine de la réalité virtuelle, des jeux informatiques, de e-sport et autres. Le résultat technique consiste en un positionnement précis du son dans l'espace virtuel depuis différentes directions d'émission sonore, une immersion dans une scène sonore et l'obtention d'une carte sonore complète avec des sources de son multidirectionnelles. Ce résultat est atteint grâce à des écouteurs rapportés comprenant un corps droit et un corps gauche avec une chambre acoustique interne, qui sont connectés entre eux de manière à pouvoir les disposer sur la tête d'un utilisateur. Le corps de chaque écouteur est de forme rectangulaire avec des arrondis sur les bords et la paroi arrière. Dans chacune des parois latérales, supérieure, inférieure et arrière se trouve une ouverture, et des enceintes sont disposées dans chacun desdites ouvertures latérales et des parois supérieure et inférieure orthogonalement et parallèlement à leur paroi, tandis qu'une enceinte centrale est disposée dans la paroi arrière parallèlement à celle-ci. Toutes les enceintes peuvent être connectées à une source de signal sonore. Les diffuseurs des enceintes sont orientés vers l'intérieur de la chambre.
