The thermoacoustic engine is a sound generator which utilizes thermoacoustic effect to realize conversion from heat energy to sound energy so as to realize sound power output. The thermoacoustic effect is a physical phenomenon in which heat causes acoustic self-oscillation in an elastic medium (often a high pressure inert gas). The heat is converted into pressure fluctuation by utilizing the thermo-acoustic phenomenon that the heat generates self-oscillation in the pressure gas, wherein the pressure fluctuation is alternating mechanical energy, and the conversion of the heat energy and the mechanical energy is further realized.
