Abstract
A thermoacoustic module includes a substrate, at least one first electrode and at least one second electrode located on the substrate, a sound wave generator, and at least one spacer. The sound wave generator is electrically connected to the at least one first electrode and the at least one second electrode. The at least one spacer is located between the substrate and the sound wave generator. The at least one spacer supports the sound wave generator. An interval is defined between the sound wave generator and the substrate. The sound wave generator is embedded in the at least one first electrode and the at least one second electrode.
