Multilayer modelling of thermoacoustic sound generation for carbon based nanomaterial thermophone
Résumé
The thermoacoustic effect is based on applying an alternative current to a material with a high thermal conductivity and a low thermal capacity. The heat profile of the material follows the current profile and the compression dilatation of the air on the surface of the material due to the fluctuating temperature generates an acoustic wave whose frequency is proportional to the input frequency of the current. Since no resonating part are involved in the process the generation is wideband.
