<p>PURPOSE: A vibration actuator is provided to simplify an assembly process by reducing the number of internal configuration components. CONSTITUTION: A housing (110) provides an internal space. A piezoelectric element (120) is combined to an inner one side of the housing. A mass body (130) is arranged on the upper side of the piezoelectric element. A first elastic member (140) is arranged between the piezoelectric element and the mass body and elastically supports the mass body. A second elastic member (150) is arranged between the housing and the mass body and elastically supports the mass body.</p>
