A loudspeaker drives an audio current through a coil (an electromagnet) placed in a permanent magnetic field, and the changing current produces varying magnetic forces that make the coil move back and forth. That motion pushes and pulls the attached cone (diaphragm), creating pressure waves in the air that we hear as sound.
