Abstract

La présente invention concerne un écouteur dans un système d'écouteur à plusieurs canaux, ledit écouteur comprenant une unité avant comportant un haut-parleur avant qui reçoit un signal sonore correspondant à l'avant en provenance de l'équipement sonore et reproduit le signal sonore reçu, et un tube de résonance avant tubulaire cylindrique qui est relié au haut-parleur avant et à l'intérieur duquel est formée une chambre avant; une unité arrière comportant un haut-parleur arrière qui reçoit un signal sonore correspondant à l'arrière en provenance de l'équipement sonore et reproduit le signal sonore reçu, et un tube de résonance arrière tubulaire dont une extrémité est reliée au haut-parleur arrière et l'autre extrémité est reliée à la chambre avant du tube de résonance avant pour faire résonner le son reproduit par le haut-parleur arrière et amener le son résonnant vers la chambre avant; et une unité centrale comportant un haut-parleur central qui reçoit un signal sonore correspondant au centre en provenance de l'équipement sonore et reproduit le signal sonore reçu, et un tube de résonance central tubulaire dont une extrémité est reliée au haut-parleur central et l'autre extrémité est reliée à la chambre avant du tube de résonance avant pour faire résonner le son reproduit par le haut-parleur central et amener le son résonnant vers la chambre avant. Dans un tel système d'écouteur à canaux multiples, des sons clairs et naturels sont reproduits grâce à une structure de tube de résonance destinée à créer artificiellement l'écart de temps généré par l'espace sonore, qui permet de générer un écart de temps idéal dans le champ acoustique. De plus, le champ acoustique est produit sans complément de configuration, ce qui simplifie le système.
