Improved device for generating and modulating sensory signals comprising: - an electrical power supply source (1); - at least one sensory reproduction element (11, 13); - an electronic circuit (2) powered by the said electrical source (1) including: &cirf& a control input sending out electrical pulses when it is activated; &cirf& an oscillator, intended to deliver an electrical signal of defined fixed frequency; &cirf& a control logic assembly associated with a frequency divider intended to modulate the frequency of the electrical signal delivered by the oscillator, characterised in that the electronic circuit (2) further includes a detector of the duration of activation of the control input of the said circuit, intended to generate digital signals of different type depending on the activation duration thus detected, the said digital signals being transferred to the control logic assembly. Applications: miniature vehicles. <IMAGE>
