CA 2658444

A method of providing an audio signal to a headphone apparatus for a user is disclosed. The method comprises providing a headphone apparatus comprising at least one left speaker for a left ear of a user having a sound path from the left speaker to the left ear canal and at least one right speaker for a right ear of the user having a sound path from the right speaker to the right ear canal, wherein the sound path of the left speaker has a different length from the sound path of the right speaker. The method further comprises sending an audio signal simultaneously to the left speaker and right speaker thereby creating a timing difference in the time the signal is received by each ear canal based on the difference is the length of the sound path.

L'invention porte sur un procédé de transmission d'un signal audio à un casque d'écoute. Un tel casque comporte au moins un écouteur gauche pour l'oreille gauche présentant une trajectoire sonore reliant l'écouteur gauche au conduit auditif gauche, et au moins un écouteur droit pour l'oreille droite présentant une trajectoire sonore reliant l'écouteur droit au conduit auditif droit, la trajectoire sonore de l'écouteur gauche ayant une longueur différente de celle de l'écouteur droit. Le procédé consiste à envoyer simultanément aux deux écouteurs un même signal audio qui du fait de la différence de longueur des trajectoires sonores est reçu dans les deux conduits auditifs avec un décalage de temps.
