Abstract
The present disclosure provides a digital sound projector including an insulated panel, a number of acoustic cells and a signal processing device. The number of acoustic cells is located on a surface of the insulated panel and spaced apart from each other. Each one of the number of acoustic cells includes an acoustic element, a first electrode, and a second electrode. The first electrode and the second electrode are spaced apart from each other and electrically connected to the acoustic element. The signal processing device provides a number of delayed electrical signals to the acoustic element. Each one of the acoustic elements includes a carbon nanotube film structure.
