A speaker, or loudspeaker, is a device that converts electrical signals into sound. They do this by using that electrical signal to vibrate a cone-shaped device at particular frequencies that are encoded by the signal, which produces sound. Larger cones are better at making low sounds, smaller ones are better at making high sounds.
