<p>The present invention relates to an arrangement for wireless earphones applicable in audio - systems or audio - visual systems of all kinds. The present invention overcomes the problem of the high construction, installation, operation, repair and maintenance cost of the wireless earphones of the prior art, due to the batteries and electronic circuits employed by the same, by means of a new system of wireless earphones without batteries and electronic circuits, whose operation is based on the inductive coupling between a space coil and an earphone coil, where the order of inductive coupling depends on the height of installation of the space coil, the circumferential length and number of turns of the two coils, the kind of used cores in the coils (air - or magnetic materials) and specific resistances of the materials used.</p> |
