How do IC chips work?

[oddaaron00]

Say there was a bog-standard motherboard. During production, an IC audio chip was added and now the motherboard is capable of outputting sound. How does this IC chip allow sound to be outputted from the computer? As in, how does a plastic and metal block create sound?
Thanks!
