This is NOT a speaker this is solely for troubleshooting and as a diagnostic tool. You may have noticed that when you first turn on your computer, it emits a short, single beep. This beep does more than tell you that you just turned on your computer. That single beep is actually a beep code that tells you everything is OK with your PC. Working in tandem with the motherboard, the internal speaker will emit a series of beep codes both long and short and also steady and intermittent to indicate to the troubleshooter what the source of the error is.
