The invention provides a broadband vibration signal sensor and a signal processing device thereof. The broadband vibration signal sensor comprises: a base; a shell which is arranged on the base in a covering manner; a signal processing module which is arranged in the accommodating cavity or outside the accommodating cavity; a piezoelectric component which is arranged in the accommodating cavity and is stacked on the base; a piezoelectric element which is arranged in the accommodating cavity and is stacked on the piezoelectric component; and an elastic element which is arranged in the containing cavity and stacked on the piezoelectric element,whereinthe side, away from the piezoelectric element, of the elastic element is connected to the inner wall of the shell. According to the broadband vibration signal sensor provided by the invention, the piezoelectric element and the piezoelectric component are arranged, and the piezoelectric element is stacked on the piezoelectric component, so that low-frequency vibrati
