摘要：
A speaker includes a thermoacoustic module, an amplifier circuit board, and a frame. The thermoacoustic module includes a sound wave generator, at least one first electrode and at least one second electrode. The at least one first electrode and the at least one second electrode are electrically connected to the sound wave generator. The sound wave generator includes a carbon nanotube structure. The amplifier circuit board is electrically connected to the carbon nanotube structure by the at least one first electrode and at least one second electrode. The frame secures the thermoacoustic module and the amplifier circuit board.
