Abstract: Disclosed is a vibration generating method includes providing a vibration generating device which receives a driving power and generates a vibration, and controlling vibration of a vibrator of the vibration generating device, wherein the vibration of the vibrator is controlled by systematizing an inertia matrix and a stiffness matrix of the vibrator, and wherein the inertia matrix and the stiffness matrix simultaneously satisfy diagonalization. A vibration generating device using this method is also disclosed.
