Abstract

Selon certains modes de réalisation, l'invention concerne d'une manière générale des systèmes et des procédés permettant de déterminer si un casque d'écoute est porté, et d'activer ou de désactiver l'alimentation d'un ou de plusieurs éléments du casque d'écoute. Le casque d'écoute peut comprendre deux protège-oreilles munis d'éléments d'annulation active du bruit, un serre-tête, une jauge de contrainte attachée au serre-tête et permettant de détecter une flexion du serre-tête, au moins un microphone placé à l'intérieur d'un protège-oreilles, et une unité de commande permettant d'alimenter un ou plusieurs des éléments du casque d'écoute. L'unité de commande reçoit des informations provenant de la jauge de contrainte et des microphones et indiquant si le casque d'écoute est ou non porté par un utilisateur, l'unité de commande active l'alimentation du casque d'écoute si le casque d'écoute est porté par un utilisateur, et l'unité de commande désactive l'alimentation du casque d'écoute si le casque d'écoute n'est pas porté par un utilisateur.
