关键词	Restraining the noise meanwhile improving the dynamic characteristics of the driving power of piezoelectric pump effectively are the final purposes of doing research on the reciprocating and flexural vibration of the piezoelectric vibrator. However among many papers regarding piezoelectric pump there are very few papers about the research on the noise of piezoelectric pump. This is far less than the research on the application of the piezoelectric pump in other fields. In this paper the research on the flexural vibration deformation and vibration radiation noise of the piezoelectric vibrator are carried out. Firstly the vibration equations of the piezoelectric vibrator are built and flexural vibration deformation function is deduced. Then the simplified vibration model of the piezoelectric vibrator is introduced by using vibration theories of micro-area piston. Furthermore theoretical calculation equations of sound pressure in close noise field and noise contribution equation of fluid in pump are deduced. Finally a comparison is made between the theoretical calculation value and experimental value and the contribution quantities of the piezoelectric vibrator and fluid in pump are obtained respectively under different frequencies. The consequence approves that the theory introduced by this research is true. 2006 IEEE.
