CASCADED THERMOACOUSTIC DEVICES

摘要

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 (84, 86) are cascaded together within the region of high specific acoustic impedance, where at least one of the thermoacoustic units (84, 86) is a regenerator unit.
