Zusammenfassung:	PURPOSE: A vibration amplification synthetic jet actuator generating more powerful synthetic jet with a higher vibration displacement is provided to generate more powerful jet with a higher vibration displacement and have a simple structure to be easily manufactured. CONSTITUTION: A vibration amplification synthetic jet actuator includes a vibration generator, a chamber and a control unit. The vibration generator generates vibration according to applied power supply. A chamber including an elastic member(50), a mass upper plate(60), a lower plate(70) and at least one orifice(110) placed on the mass upper plate or an elastic member is adhered to the vibration generator. The control unit controls power supplied to the vibration generator. The vibration generator is composed of a piezoceramic stack. The vibration generator includes an elastic body sheet(40), a piezoceramic adhered on a surface or both surfaces of the elastic body sheet and a connection protrusion connecting the elastic body sheet and the chamber. An elastic member is bellows having a metal material. A coil spring mounted inside the chamber is additionally included.
