A device that converts analog audio signals into the equivalent air vibrations in order to make audible sound. Although CRT usage has faded, speakers designed for computers are shielded to avoid magnetic interference with the CRT's magnetic coil.

Starting in the 1990s, vendors began to offer higher-quality computer speakers. Similar to home theater and stereo systems, many computer speaker systems include a pair of small speakers for the midrange and high (treble) frequencies and a large subwoofer for the low end (bass). The small speakers are placed in a left/right stereo orientation, while the subwoofer can be located anywhere on the floor because bass signals are omnidirectional. See sound card and subwoofer.
