Use sound exicter to produce vibration with esp32

AndrewT

Hi everyone! I want to use a sound exciter as a haptic motor which produces the vibration. However, it always makes some noise.

How can I reduce the noise as much as possible? eg the editing program.

Thank you!

  • Sound exciters only make a noise because the wave form it produces resonates across a surface. Thus if you removed the sound exciter from any surface it won't make much noise.

    Similarly, if you placed a haptic motor on a cardboard box then it too will make noise as the high frequency vibrations resonate across the cardboard surface.

    So if you set a constant frequency and control the amplitude of the sound wave through the sound exciter then it will mimic a vibration effect at that set frequency.
