Abstract
A method of making a thermoacoustic device includes molding and cutting laminated sheets into half shell portions. Carbon nanotubes are adhered to a substrate having two electrical conducting portions thereon. Electrical conductors are applied to the conducting portions of the substrate. Tab sealant strips are applied around the perimeter of the substrate. Half shell portions are positioned on the top and bottom of the substrate with the electrical conductors extending therefrom. Heat is applied to seal the half shell portions together, suspending the substrate from the tab sealant strips. The method can further include providing a tube between the half shell portions prior to applying heat.
