Abstract

The invention relates to a device allowing very discreet communication between a control room and a set. It consists of an H.F. system whose receiver has a power output. This output is connected to an induction coil which may take the form of a necklace or belt and which emits a magnetic flux. This flux is received by a miniature induction coil disguised in a shell having the shape of the acoustic duct. This shell also encloses an amplifier and its battery supply as well as an earpiece. The device according to the invention is particularly indicated for communication between producer or sound engineer and live televised broadcast presenter.

Description

La présente invention concerne un dispositif de liaison audio entre une régie et un interlocuteur sur un plateau. The present invention relates to an audio link device between a control room and an interlocutor on a set.

Les relations entre une régie et un plateau s'effectuent généralement â l'aide de liaisons téléphoniques classiques, cette solution est çênante lors d'émission en direct : sonnerie, rupture du cours normal du direct
Les relations peuvent également s'effectuer gracie a des liaisons
H.F., le récepteur H.F. étant relié par un fil a un petit écouteur logé dans l'oreille , cette solution est très inesthétique ce qui empêche son utilisation lors d'emJssion télévisée.The relations between a control room and a stage are generally carried out using conventional telephone links, this solution is c lorsnante during live transmission: ringing, breaking the normal course of direct
Relationships can also be made thanks to connections
HF, the HF receiver being connected by a wire to a small earpiece housed in the ear, this solution is very unsightly which prevents its use during TV broadcast.

Le dispositif selon l'invention permet de remédier a ces deux inconvénients . Il comporte en effet un système de liaison H.F. dont le récepteur possède une sortie " en puissance " . Cette sortie est reliée à une bobine d'induction émetant un flux . Ce flux est reçu par une petite bobine d'induction qui sert de transducteur d'entrée à un petit amplificateur {alimenté par une pile "bouton") relié a un écouteur miniature . La petite bobine, l'ampli, la pile et l'écouteur étant logés dans une coque a la forme du conduit auditif. The device according to the invention overcomes these two drawbacks. In fact, it includes an H.F. link system, the receiver of which has a "power" output. This output is connected to an induction coil emitting a flux. This flux is received by a small induction coil which serves as an input transducer to a small amplifier (powered by a "button" battery) connected to a miniature earphone. The small coil, the amplifier, the battery and the earpiece being housed in a shell in the shape of the ear canal.

Selon sna forme de rFalisation prférentielle, la bobine d'émission b la forme d'un collier a placer autour du coup . Ce collier servant de sangle au recepteur H.F. According to its preferred embodiment, the transmission coil b has the form of a collar to be placed around the blow. This necklace serving as a strap for the H.F.

Selon une variante , la bobine d'émission a la forme d'une ceinture à placer autour de la taille . Cette ceinture servant de sangle au recepteur H.F. According to a variant, the transmission coil has the shape of a belt to be placed around the waist. This belt serving as a strap for the H.F.

Selon une forme de réalisation préférentielle, la coque intra auriculaire pourra être réalisée sur mesure pour obtenir une discrétion optimale. Cette coque étant réalisée comme pour celle des aides auditives pour malentandant
Selon une variante des coques standards pourront Store envisagées.According to a preferred embodiment, the in-ear shell can be made to measure to obtain optimal discretion. This shell being made as for that of hearing aids for the hearing impaired
According to a variant of the standard shells may Store envisaged.

Le dispositif selon l'invention est particulièrement destiné aux communications entre réalisateur et présentateur d'émission télévisée en direct.  The device according to the invention is particularly intended for communications between producer and presenter of live television broadcasts.
