THERMOACOUSTIC DEVICE

A thermoacoustic device includes a first electrode, a second electrode and a sound wave generator. The first electrode includes a first electrical conductor and a first conductive adhesive layer located on the first electrical conductor. The second electrode includes a second electrical conductor and a second conductive adhesive layer located on the second electrical conductor. The sound wave generator includes a carbon nanotube structure, and the sound wave generator is electrically connected to the first electrical conductor and the second electrical conductor via the first and second conductive adhesive layers. The adhesive layers permeate into the carbon nanotube structure.
