  3. Computer speakers, or multimedia speakers, are external speakers, commonly equipped with a low-power internal amplifier. The standard audio connection is a 3.5mm (1/8 inch) stereo jack plug often color-coded lime green (following the PC 99 standard) for computer sound cards. A few use an RCA connector for input. There are also USB speakers which are powered from the 5 volts at 200 milliamps provided by the USB port, allowing about 1-watt of output power. www.assignmentpoint.com

  4. Computer speakers range widely in quality and in price. Computer speakers sometimes packaged with computer systems are small, plastic, and have mediocre sound quality. Some computer speakers have equalization features such as bass and treble controls. More sophisticated computer speakers can have a subwoofer unit, to enhance bass output. The larger subwoofer enclosure usually contains the amplifiers for the subwoofer and the left and right speakers. www.assignmentpoint.com

  5. An unusual design by HiWave Technologies, the DyadUSB USB-powered stereo audio amplifier module used in the Sound Science QSB 30W Portable USB Speakers allows a USB-powered and driven stereo speaker pair to supply 30W of power for short periods with a signal that has short high-power peaks and much lower average power, as most music and speech does. It stores energy from the USB connection during quieter periods, delivering high power for the peaks. www.assignmentpoint.com
