Improved circuit adaptable to toy telephones, essentially characterized by the fact of establishing an electrical circuit in series with two handsets, in which contactors are provided combined with the displacement of the mechanical devices that support the microphone and the headset, finding a second circuit additional in combination with the previous one and fed, like that, from a battery, through whose additional circuit the call is made from one to another device, called which is connected by the possible actuation of rotating discs that contact in their rotation with plate solidaria of the opposite polarity, closing the circuit of an electromagnet that acts on a vibrating plate of great loudness, whose call circuit is opened by the own movement of the mechanical devices that support the microphone and the receiver.
