Abstract

La présente demande, qui appartient au domaine technique des dispositifs électroniques, concerne un dispositif de transmission d'énergie électrique, un circuit de commande, un adaptateur, une boîte de charge et un système de charge. Dans un dispositif de transmission d'énergie électrique, une première interface est utilisée pour être électriquement connectée à une alimentation secteur et pour recevoir de l'énergie électrique de l'alimentation secteur ; une deuxième interface est utilisée pour être électriquement connectée à un dispositif électronique et/ou à une alimentation électrique mobile et pour transmettre de l'énergie électrique ; une troisième interface est utilisée pour être électriquement connectée à un écouteur et pour réaliser une transmission d'énergie électrique avec l'écouteur ; et un circuit de commande est utilisé pour commander une transmission d'énergie électrique entre la première interface et la deuxième interface, et est utilisé pour commander une transmission d'énergie électrique entre la première interface et la troisième interface. Dans la présente demande, l'écouteur peut être placé dans le dispositif de transmission d'énergie électrique de sorte que, lorsqu'un utilisateur porte le dispositif de transmission d'énergie électrique, il n'est pas nécessaire de porter une boîte de charge d'écouteur ni un adaptateur correspondant à la boîte de charge d'écouteur, ce qui facilite le port ; et durant l'utilisation, l'adaptateur peut être utilisé pour être en connexion électrique directe avec l'alimentation secteur pour charger le dispositif électronique, l'alimentation électrique mobile et l'écouteur, ce qui permet à l'utilisateur de les utiliser continuellement pendant une longue période.
