A wind energy generator using a piezoelectric material and an auxiliary mechanism thereof are disclosed. The wind energy generator comprises the auxiliary mechanism and the piezoelectric material. The auxiliary mechanism comprises a wind collecting device and a wind driving device. The wind collecting device is used for collecting a wind and increasing the wind speed. The wind driving device cooperates with the wind collecting device to receive the wind. The piezoelectric material contacts with the wind driving device. When the wind collecting device receives the wind, the piezoelectric material is vibrated by the wind via the wind driving device to generate an electric power.
