Computer speaker
From Wikipedia, the free encyclopedia
Computer speakers, or multimedia speakers, are external speakers and are usually equipped with a male-end stereo jack plug (usually color-coded lime green as for the PC 99 standard) for computer sound cards; however, there are some that have female RCA connector, and some people link computer sound cards to nearby stereo systems. There are also USB speakers which gain their power from the 5 volts of a USB port. Computer speakers are usually a simplified stereo system without a radio or other media sources built in.
Computer speakers range widely in quality and in price. Typically, the simplest computer speakers come with computers. There are also advanced forms of computer speakers that have graphic equalization features (bass, treble, etc.) for dynamic audio flexibility.
It is common to connect active/powered computer speakers to a power strip. The power outlet should preferably be grounded.
