A CD player is used to play music from a CD. There are personal CD players that are used with headphones and CD players that are part of a stereo system.
The first company to sell CD players was Sony. The first product was launched in Japan in 1982. The first CD player sold by Sony was called the Sony CDP-101.
CD players are used to convert electrical energy (from the power source) into sound energy (produced by the speakers).
