Abstract

Improved telephone amplifier, essentially characterized by being constituted from a prismatic body with trapezoidal side faces, on whose upper base, which is slightly domed, there are extremely deep recesses that affect even the smaller faces of the body, so that one of them, the one located in the area of lower height, will receive the part of the telephone that includes the hearing aid, having provided in a central area comprised between the aforementioned recesses a floating arm that acts as support for the telephone receiver-transmitter, with whose weight, said arm closes the power switch of the transistorized amplifier circuit.
