Improvements introduced in the procedures to increase the resonance in all kinds of watchmaking devices characterized by the fact that an eccentric provided with as many projections or cams as hour signals are desired per hour that actuate a rod that opens or opens on the clock's minute axis. It closes the power circuit of a sound amplifier whose microphone is placed immediately to the sound of the clock whatever the type of it while a speaker or speakers in communication with the amplifier spread the signals or notes.
