text: A DC circuit will not make any sound; there is no change of direction of electricity current flow, so the driver of a speaker driven by DC will just be moving either in OR out, and stays in or out as long as there is a current, but NOT both in AND out, because the DC is creating force on the motor structure of the speaker driver in only one direction due to the one direction flow of the current.
