A variable-frequency low-frequency vibration energy acquisition and management system belongs to the field of energy acquisition and management circuits. The energy input end of the control circuit (2) is connected with the energy output end of the energy acquisition main circuit (1), and the signal output end of the control circuit (2) is connected with the signal input end of the energy acquisition main circuit (1); the energy output end of the energy collector (3) controls the energy input end of the circuit (2) and the energy input end of the isolation transformer (8) at the same time, the energy output end of the isolation transformer (8) is connected with the rectification circuit (5) in series and then connected with the energy storage module, and the energy output end of the isolation transformer (8) is further connected with a flyback conversion circuit (10) used for supplying power to a direct-current load. According to the invention, the energy collector outputs more electric energy, and maximum po
