Abstract
A thermoacoustic module includes a substrate, at least one first electrode and at least one second electrode located on the substrate, a cover board spaced from the substrate, and a sound wave generator. The sound wave generator is located between the cover board and the substrate. The sound wave generator is electrically connected to the at least one first electrode and the at least one second electrode. The sound wave generator is capable of generating sound by causing a thermoacoustic effect.
