A new type of home appliances of shock absorber is designed based on the modal analysis and the static structure analysis of finite element software ANSYS software. This shock absorber is consisted of piezoelectric ceramic and Diamond Shape displacement amplification. The magnification of the shock absorber is calculated to above 3.30.Next test on the impedance analysis, low temperature performance detection, vibration and noise reduction test are carried on. Test results show that the shock absorber can inhibit the vibration and noise of the appliance with certain frequency band, the maximum reduction can be 32%.
