Piezoelectric power generations refer to the piezoelectric integrated structure which realize the transformation of conversion from environmental vibration based mechanical energy to electric energy. A new type of vibration energy generator with cantilever beam structure is designed in this paper. In order to reveal the underlying of piezoelectric transducer mechanism, the vibration mechanics analysis is carried out by establishing a mathematical model, namely, the vibration mechanism of cantilever beam caused by external vibration excitation is described by using spring mass block damping single degree of freedom system model.  In order to get the vibration generator with reasonable structure and excellent performance, frequency response and transient, the relationship between the cantilever thickness, cantilever width, cantilever length and vibration characteristics are optimazed by using COMSOL-Multiphysics FEM simulation software to model and analyze the generator body. To evaluate the output performance of the piezoelectric module, finite element modeling and analysis is conducted. According to the evaluation, the design of electromagnetic and -piezoelectric composite vibration generator presented in this paper is proising for environmental vibration based energy harvest.
