The invention discloses a thermoacoustically driven magnetic fluid power generation system which adopts room temperature ionic liquid. The invention includes a first loop of traveling wave thermoacoustic core, a resonance tube, room temperature ionic liquid, a power generation device and a second loop of traveling wave thermoacoustic core which are connected sequentially ; the invention also includes a frequency stabilizer between the two traveling wave thermoacoustic cores. The traveling wave thermoacoustic core loop includes a feedback tube, an acoustic inductance tube, an acoustic capacitance tube, a first water cooler, a heat regenerator, a heater, a thermal buffer tube and a second water cooler. The power generation device is composed of a rectangle stainless steel outer sleeve, a insulation interlayer, a permanent magnet, electrodes and connecting terminals; and also includes the room temperature ionic liquid which surges periodically. The frequency stabilizer is connected with the traveling wave thermoacoustic cores by two stop valves through two gas storages which has two regulating valves. The thermoacoustically driven magnetic fluid power generation system of the invention brings room temperature ionic liquid into the traditional thermoacoustic engine as the liquid piston, and forms a coupling surge by two phase working medium of gas and liquid; the surge drives the ionic liquid to move back and forth to cut the magnetic line perpendicular to the moving direction, thereby realizing the generation of electricity power.
