Abstract
La présente invention concerne un procédé permettant de déterminer la polarité des microphones dun casque découte. Comme il est en mesure de détecter la polarité des microphones dun casque découte, un dispositif électronique portatif peut être compatible avec tout casque découte, et son utilisation ne se limite pas à un casque découte en particulier. En appliquant un signal de détection à une des lignes dun câble de casque découte, un signal de retour peut être capté sur lune ou lautre des lignes pour déterminer laquelle est la ligne au sol et laquelle est la ligne de microphone.
