Abstract

Cette invention concerne une unité modulaire (930) ayant un composant pour les télécommunications (950), un circuit de commutation (940) et un organe de liaison (970) avec casque, ladite unité étant conçue pour se raccorder à un dispositif électronique hôte (910). Ledit organe de liaison (970) avec casque, intégré à l'unité modulaire, communique (930) avec un organe de liaison avec l'unité modulaire, intégré au casque (980). Ce casque d'écoute (980) comporte également des écouteurs ou un haut-parleur (982), un microphone (984) et un panneau de commande (986) reliés électriquement à l'organe de liaison (990) avec l'unité modulaire, intégré au casque d'écoute (980). Le haut-parleur (982), le microphone (984) et le panneau de commande (986) du casque d'écoute (980) communiquent avec l'organe de liaison (970) avec le casque, intégré à l'unité modulaire (930), par l'intermédiaire de l'organe de liaison (990), intégré au casque (980). Le circuit de commutation (940) de l'unité modulaire (930) vérifie que l'organe de liaison (970) avec le casque, intégré à l'unité modulaire (930), est bien électriquement relié au composant de télécommunications (950) de l'unité modulaire (930) ou à un composant électronique acoustique (920) du dispositif électronique hôte (910).
