Abstract
A thermoacoustic device includes an outer shell having two half shells, each half shell having an outer flange and an inner region. The half shells are joined at the outer flanges such that the combined half shell inner regions define an inner cavity. A gas is provided within the outer shell inner cavity, and a substrate having electrodes is supported within the outer shell. A thermoacoustic element is mounted on the substrate in contact with the electrodes. Leads extend into the shell where they are joined to the electrodes. In further embodiments, the device is provided with a gas source and a regulator for controlling gas pressure in the inner cavity.
