CD Player
From Wikipedia, a free encyclopedia written in simple English for easy reading.
A CD player is an electronic device used to read the information off the surface of a Compact Disc and turn that information into sounds, such as music or spoken word.
When a Compact Disc (called a CD) is placed into the CD player, a laser (a light beam) strikes the surface of the disc as it revolves (spins around). The laser moves back and forth at one side of the disc, but because the disc is spinning, the laser can read the whole disc. As the CD player is reading the disc like this, the electronics turn what the laser reads into sound.
CD players can be attached to Hi-fi systems at home, or can be small enough to take with you (portable CD player) or can be part of a car's dashboard so that you can listen to CDs when driving.
