An efficient thermoacoustic prime mover has been built by Backhaus and Swift (Nature 339 (1999) 335). They have demonstrated that this engine produces an acoustic power with the thermal efficiency of 30%. We succeed in developing a thermoacoustic Stirling cooler as its application by inserting a regenerator inside the prime mover. Since this cooler has no moving parts and has a potential to be an efficient device, it is a powerful tool to generate low temperatures.
