The "Speaker Icon"

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.
