Abstract

Telephone intercom device which can be coupled and incorporated into radio devices, characterized in that the low frequency amplifier, the transformer arranged at the output thereof and the receiver loudspeaker, form part of the circuit of the main station of the intercom by the addition of a transformer of coupling, whose primary is interleaved in the circuit of said speaker and the secondary is connected to the low frequency amplifier of the receiver, by means of switches arranged in the respective circuits, adding also a third switch with two positions corresponding to the input of the speaker to the coupled transformer or the output of the transformer from the receiver to the loudspeaker.
