Abstract
A thermoacoustic device is formed with a resonator system defining at least one region of high specific acoustic impedance in an acoustic wave within the resonator system. A plurality of thermoacoustic units are cascaded together within the region of high specific acoustic impedance, where at least one of the thermoacoustic units is a regenerator unit.

A thermoacoustic device comprising:
- a resonator system defining at least one region of high specific acoustic impedance in an acoustic wave within the resonator system;
- a plurality of thermoacoustic units cascaded together within the region of high specific acoustic impedance , where at least one of the thermoacoustic units is a regenerator unit.
A thermoacoustic device comprising:
- a resonator system defining at least one region of high specific acoustic impedance of an acoustic wave within the resonator system;
- at least two regenerator units connected in series within the region of high specific acoustic impedance.
