1. A method of controlling vibration, the method comprising:

  • receiving a call;

    determining whether an electronic device is set to a vibration mode;

    determining whether the electronic device is located on a flat surface if the electronic device is set to the vibration mode;

    driving a vibration motor at a first vibration intensity if the electronic device is located on the flat surface;

    measuring a noise signal level by using a microphone of the electronic device during receiving the call;

    filtering the measured noise signal level to remove a noise signal generated due to the vibration of the vibration motor;

    adjusting the driving intensity of the vibration motor to a second vibration intensity based on the filtered noise signal level; and

    repeating the measurement, the filtration and the adjustment during receiving the call,wherein the adjusting of the driving intensity of the vibration motor comprises;

    determining whether a difference of the measured noise signal level and the filtered noise signal level is less than a threshold,increasing the driving intensity of the vibration motor if the difference is less than the threshold, andmaintaining a current driving intensity of the vibration motor if the difference is greater than the threshold.
