Abstract
We have developed a thermoacoustic electric generator consisting of a looped tube thermoacoustic engine and a voice coil type generator in place of an acoustic resonator. On the basis of measurements of the acoustic impedances of the looped tube engine and the generator, we modified the electric generator to make their acoustic impedances to become the same as each other. The thermoacoustic electric generator thus constructed oscillates at the frequency much lower than that expected from the engine size.
