Wireless sound transmission headset, has pulsed infrared source or emitter emitting infrared ray, and plastic housing carrying loudspeaker, where housing is placed around ear through elastic flexible wire that connects source and earpiece

The headset has a pulsed infrared source or emitter (1) i.e. lamp, emitting an infrared ray. A cell is associated to a resistor-capacitor circuit that is adjusted for a given pulse duration, and supplies the infrared ray with variable frequency. An inductor (4) guides the infrared ray towards a soun...

description The headset has a pulsed infrared source or emitter (1) i.e. lamp, emitting an infrared ray. A cell is associated to a resistor-capacitor circuit that is adjusted for a given pulse duration, and supplies the infrared ray with variable frequency. An inductor (4) guides the infrared ray towards a sound memory (5) that stores sound elements such as music and commercial or technical discussion. A plastic housing carrying a loudspeaker (6) is placed around an ear through an elastic flexible wire (8) that connects the source and an earpiece. La présente invention concerne une oreillette à transmission sonore dépourvue de fil de liaison entre le boîtier et l'oreille d'un individu.Selon le dessin de l'abrégé, le dispositif comporte une source infrarouge (1) équipée d'une alimentation à pile (2) pulsée au moyen d'un circuit résistance capacité qui alimente de façon séquentielle l'émetteur infrarouge (1). Le rayon infrarouge alimente par impulsion les mémoires sonores reliées en haut parleur
