摘要：
Carbon nanotube (CNT) sheets drawn from vertically grown CNT forests have the potential for application to thermoacoustic systems. The small heat capacity of the CNT sheet leads to a high sound pressure level by the input AC signal. We show through various assemblies with different structural parameters that the electrical properties of CNT sheet speakers and the heat spreading into the surrounding medium are closely related to the sound pressure levels.
