In computing, a speaker, also called a loudspeaker, is a hardware device, an electroacoustic transducer that generates sound in response to the electrical audio signal input.
They are usually made from a cone, a magnet, and an iron coil all fitted in a case. The speakers receive the electrical input current and make it move. This motion generates the sound waves we hear.
Initially, speakers were onboard computer devices, invented by IBM in 1981. The sound produced had low quality.
Further, they moved in monitors and were capable of creating voices, music, and other sound effects. Once with the evolution of games, high-quality external speakers were made.
