Loudspeakers

Loudspeakers are devices that convert electrical signals into sound so we can hear audio from music, movies, or speech. They consist of components like a cone (called a diaphragm), a magnet, and a coil. When an electrical signal flows through the coil, it creates a magnetic field that moves the cone back and forth. This movement pushes and pulls the air around the speaker, generating sound waves. Essentially, loudspeakers transform electrical energy into mechanical energy, producing audible sound waves that let us hear the audio content.
