A vibration generating device includes a motor having a rotation shaft, a rotating body attached to the rotation shaft, a rotation control unit configured to control rotation of the motor, and magnetic generating unit which is disposed at a non-contact position with the rotating body. The rotating body has the center of gravity positioned on an axis of the rotation shaft, is formed of a magnetic material, and generates vibration by a magnetic attraction force applied to the magnetic material by a magnetic field from the magnetic generating unit when the rotating body is rotated.
