ABSTRACT:
An electromechanical vibrator driving device comprising a rhythm signal generator to produce rhythmic pulses in a pattern corresponding to a beat pattern of a selected music rhythm, the rhythmic pulses being amplified and then applied to the vibrator so that the vibrator generates a rhythmical vibration of the selected music rhythm. The rhythm signal generator comprises a rhythm pattern generator storing different rhythm patterns and providing pulses corresponding to strong beats and pulses corresponding to weak beats in a selected rhythm pattern, separately. The strong beat pulses and the weak beat pulses are processed by attenuators to have different amplitudes and are mixed to produce the rhythm signal.
