A loudspeaker works by converting electrical signals into sound waves through the principles of electromagnetism and vibration. Inside the loudspeaker, an electric current passes through a coil of wire positioned within a magnetic field created by a permanent magnet. When the electrical signal flows through the coil, it generates a magnetic field that interacts with the permanent magnet, causing the coil to move back and forth. This movement drives a diaphragm, usually a cone-shaped membrane, to
