      Speakers  

The speakers that are attached to the computer are similar to the ones that are connected to a stereo. The computer system's speakers are smaller and they contain their own small amplifier. Speakers receive the sound in the form of electric current from the sound card and then convert it into sound format. Computer speakers range widely in quality and in price. The computer speakers typically packaged with computer systems are small plastic boxes with mediocre sound quality. Some of the slightly better computer speakers have equalization features such as bass and treble controls which improves their sound quality. The internal amplifiers require an external power source, known as a 'wall-wart'. Laptops come with integrated speakers.
