Abstract:
1. A thermoacoustic device comprising: a sound wave generator comprising of a first surface and a second surface; a plurality of first electrodes disposed on the first surface; a plurality of second electrodes disposed on the second surface, the first electrodes and the second electrodes are alternately arranged; and a first network and a second network, each of the first network and the second network comprises of a plurality of conducting wires, the plurality of first electrodes are connected together by the plurality of conducting wires in the first network, the plurality of second electrodes are connected together by the plurality of conducting wires in the second network; wherein the plurality of first electrodes and the plurality of second electrodes transmit an electrical signal to the sound wave generator, the sound wave generator converts the electrical signal into heat, and the heat transfers to a surrounding medium in contact with the sound wave generator to cause a thermoacoustic effect.
