Mechanism formed by a box in which there is a micromotor with output shaft coupled by belt transmission to a pulley with coaxial pinion, mounted freely on a shaft, which pinion engages in a crown which exists on a shaft which is parallel and equipped with another pinion which engages in a crown integral with the independent shaft of the pulley. A battery energy source supplies an electronic printed circuit from which the current arrives at the micromotor, this printed circuit being activated by a microphone-type acoustic sensor in order to vary the voltage and intensity applied to the motor as a function of the tone, intensity and frequency of the sound received. The output from the shaft of the reducer, with the rhythmical movement corresponding to the sound detected, arrives at a bent shaft encased in a flexible spring covering, which converts the rotational movement into a rocking movement adapted to the sound which activates the assembly. <IMAGE>
