ELI5:Why can my computer make beeping noises, but I still need speakers to listen to sounds from it?

Your motherboard has a dedicated speaker that is utilized to give beep codes. Different patterns mean different errors. 

Edit: A single beep at boot generally means it passed its POST (power-on self test) and there are no hardware problems related to the board or directly connected components.
