| Research Abstract |
We have proposed and studied the properties of thermo-acoustic CNT speakers fabricated by CNT web. The measurements reveal that the CNT speaker shows super-broad frequency response from 100 to 100 kHz, which is not realized in the conventional dynamic speakers. We also discuss that the generation mechanism of the acoustic wave from the heat dynamics and the dependence of both the resistivity of the CNT speaker and the length of the individual CNT on the acoustic properties.
