A vibration control method includes the steps of: determining whether an electronic device is loaded on a plane when a vibration event of the electronic device is generated; measuring a first noise signal level before a vibration motor is operated by using a microphone of the electronic device when the electronic device is loaded on the plane; measuring a second noise signal level after the vibration motor is driven with the minimum vibration intensity; and controlling the driving intensity of the vibration motor by comparing the first noise signal level with the second noise signal level. Thereby, an excessive noise is not generated when a portable terminal vibrates on a hard surface like a desk.
