Thermoacoustic device

摘要

A thermoacoustic device includes an electrode layer and a sound wave generator. The sound wave generator is disposed on a surface of the sound wave generator. The electrode layer includes a plurality of insulated wires and a plurality of conductive wires. The conductive wires are disposed apart from each other and crossed with the insulated wires. The sound wave generator is electrically connected with conductive wires.
