摘要
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.
