Systems and methods for manipulating acoustic energy are presented. In some embodiments, a combustion zone provides heat to a regenerator using a mean flow of compressible fluid. In other embodiments, a thermoacoustic driver is concentrically disposed within a shell to permit radial heat transfer from the thermoacoustic driver to compressible fluid within the shell, thereby preheating the compressible fluid within the shell. In other embodiments, burning of a combustible mixture within the combustion zone is pulsed in phase with the acoustic pressure oscillations to increase acoustic power output.
