AUDIO OUTPUT DEVICES

Audio output devices are the components of the computer system that produce music, speech, or other sounds, such as beeps. Common Audio Output Devices include: 

  • Computer Speakers
  • PC Internal Speakers
  • Headphones and
  • Earphones

A. COMPUTER SPEAKERS

Computer Speakers typically have tone and volume controls, allowing users to adjust settings. To boost the low bass sounds, surround sound speaker systems also include a woofer, with one or two center speakers and two or more satellite speakers that are positioned so that sound emits from all directions. Some Computer Speakers use Wireless technology.



B. PC INTERNAL SPEAKERS

Most personal computers have small internal speakers that basically output beeps and low-quality sound.






C. HEADPHONES AND EARPHONES

In a crowded computer laboratory environment, speakers might not be applicable. Instead, users can plug headphones or earphones in a port on the sound card, in a speaker, or on the front of the system unit. With headphones or earphones, only the individual wearing the headset hears the sound from the computer.
