PROBLEM TO BE SOLVED: To provide a multi-functional vibration actuator excellent in shock resistance such as dropping and easy in assembly due to a simple structure. SOLUTION: A magnetic circuit comprising a pole piece 6, a magnet 7 and a yoke 8 is supported by using a suspension 9 of a shape connecting an outer wheel and an inner wheel by a supporting part, and a suspension outer wheel part is projected from a cover 1 installing a housing 2 or a step part inside of the magnetic circuit. Thereby, the moving range of the magnetic circuit is restricted by the suspension outer wheel part and the damage of the inside of the multi-functional vibration actuator is prevented at the time of the shock such as dropping.
