The invention relates to a dynamic vibration absorber-based device for collecting piezoelectric vibration energy, and belongs to the technical field of energy utilization. The device comprises a piezoelectric element, a cover plate, a dynamic vibration absorber and an energy collecting circuit, wherein the cover plate is fixed on the piezoelectric element and is connected with the dynamic vibration absorber; and the energy collecting circuit is connected with the piezoelectric element. The piezoelectric element can be arranged on the surface of an external vibrating element conveniently to collect the small-amplitude vibration energy without being embedded in the external vibrating element or large amplitude; and the working frequency of the piezoelectric element can be designed in a higher frequency domain so as to realize the easily-applied and efficient collection of the vibration energy.
