The invention provides a standing wave type thermo-acoustic engine-driven thermomagnetic power generation system. The system comprises a standing wave type thermo-acoustic engine and a thermomagnetic power generator, wherein the thermomagnetic power generator is fixed on a soft magnetic pack (7) which is arranged in the standing wave type thermo-acoustic engine; the soft magnetic pack (7) is formed by stacking a plurality of soft magnetic material sheets in parallel; the soft magnetic pack (7) is arranged on a magnetic loop of the thermomagnetic power generator in the radial direction; the axial direction of the soft magnetic pack (7) is superposed with the propagation direction of acoustic wave generated by the thermos-acoustic engine; the standing wave type thermo-acoustic engine generates a thermo-acoustic effect through the soft magnetic pack (7); and the thermomagnetic power generator generates a thermomagnetic effect through the soft magnetic pack (7). According to the thermomagnetic power generation system provided by the invention, the thermomagnetic power generator is coupled on the soft magnetic pack of the standing wave type thermo-acoustic engine, and above functions are reused through the soft magnetic pack, so that the whole system does not have any moving component, the structure of the system is more compact and simple, the damp of the system is reduced and the service life of the system is effectively improved.
