Cause an object to oscillate or vibrate.
  • Electric carving knife with vibrating blades

Increase its frequency (even up to the ultrasonic).
  • Distribute powder with vibration.

Use an object's resonant frequency.
  • Destroy gall stones or kidney stones using ultrasonic resonance.

Use piezoelectric vibrators instead of mechanical ones.
  • Quartz crystal oscillations drive high accuracy clocks.

Use combined ultrasonic and electromagnetic field oscillations.
