Abstract

Un dispositif de transmission du son (4) pour écouteur (2), comportant une ouverture d'entrée (41) s'étendant selon un axe d'entrée, ladite ouverture d'entrée (41) étant apte à recevoir une source d'émission sonore, une ouverture de sortie (42) apte à être présentée dans une oreille (1) et une enceinte de diffusion (40) apte à conduire le son vers ladite ouverture de sortie (42), l'enceinte de diffusion (40) comportant au moins une paroi de séparation longitudinale (9) définissant au moins un canal de diffusion principal (6) et un canal de diffusion auxiliaire (7) de longueurs différentes dans l'enceinte de diffusion (40) de manière à créer un décalage dans la transmission du son à l'ouverture de sortie (42).A sound transmission device (4) for a headset (2), comprising an inlet opening (41) extending along an inlet axis, said inlet opening (41) being capable of receiving a source of sound emission, an outlet opening (42) capable of being presented in an ear (1) and a diffusion enclosure (40) capable of conducting sound towards said outlet opening (42), the diffusion enclosure (40) comprising at least one longitudinal partition wall (9) defining at least one main diffusion channel (6) and an auxiliary diffusion channel (7) of different lengths in the diffusion enclosure (40) so as to create an offset in transmitting sound to the outlet opening (42).
