Thermoacoustic device

A thermoacoustic device, comprising:

• a substrate;
• a plurality of first electrodes and a plurality of second electrodes, the plurality of first electrodes and the plurality of second electrodes being alternatively disposed on the substrate;
• a sound wave generator comprising a first surface and a second surface opposite the first surface, the first surface of the sound wave generator contacting with the first electrodes and the second electrodes, the sound wave generator comprising a carbon nanotube structure;
• a plurality of fixed elements contacting with the second surface of the sound wave generator;
• wherein the sound wave generator is suspended from the substrate.
