What is the difference between oscillator and vibrators?

Answer 1

A violin's stings vibrate at a literally infinite number of frequencies, so that is a vibration.

Oscillations occur when vibrations, from several sources, all have the same or very, very, very similar frequencies combine and become enhanced.

Answer 2

An oscillator is an electronic device that vibrate under certain criteria. a vibrator is a mechanical device that vibrates.

Answer 3

Resonator is a device used either to generate wave or select specific frequencies from a signal while oscillator is an electronic circuit that creates repetitive signal.
