Abstract

"CHILD RADIO RECEIVER" which is characterized by a circuit formed by an electromagnetic coupling of two coils wound one after another on a common insulating cylinder inside which there is a ferromagnetic core axially displaceable from the outside and a contact detector metallic so that when both elements are connected to an antenna and ground through a pair of tweezers, they produce the excitation of a dynamic receiver at sound frequencies that depend on the electromagnetic waves picked up by the antenna.
