A thermoacoustic module includes a substrate, at least one first electrode, at least one second electrode, a sound wave generator, and at least one spacer. The sound wave generator electrically connect to, span between the at least one first electrode and the at least one second electrode. The at least one first electrode and the at least one second electrode are located on the substrate and provide support to the sound wave generator. The at least one spacer is located on the substrate, 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.
