Vibration is indeed a mechanical process that causes oscillations around a point of equilibrium. The term originates from the Latin word, vibrationem (to shake or quiver). The oscillations can be regular, such as a pendulum's motion, or casual, such as rolling of tires on a gravel road. To illustrate further, the motion of a tuning spoon, the reed in a music instrument like piano, a mobile device, or the funnel of a loudspeaker are suitable for Vibration. Almost everything seems to vibrate through an external force.
