Abstract

Telephone amplifier support, essentially characterized in that it is constituted by a generally prismatic box on whose upper or support base of the telephone apparatus a magnetic plate is placed that is induced in the telephone coil and passes to an amplifier so that the oscillations convert them into sound, so that the aforementioned upper base is tilting and can close an electrical circuit, when the receiver is picked up, and said circuit being composed by a battery, the amplifier, with its corresponding speaker, as well as a manual switch, and in addition, the height or distance between the tilting contacts can be adjusted at will by virtue of the interposition of a screw, parallel to the rear wall of the box.
