PURPOSE: A vibration generator and a portable terminal thereof are provided to generate vibration to the different direction by including a main vibrator and a secondary vibrator. CONSTITUTION: A vibration generator comprises an exciting unit(11), a main vibrator(12), and a secondary vibrator(13). An exciting unit generates an electromechanical power by receiving a driving power. The main vibrator generates vibration by receiving the electromechanical power from the exciting unit. The main vibrator comprises a first elastomer(121) and a first weight(122). A first elastomer is transformed by the electromechanical power. A first weight is attached to the first elastomer. A secondary vibrator generates vibration by interlocking with the main vibrator.
