      Hehehehehe, so, essentially it comes from swallowing air:

      When you eat or drink you sometimes swallow air with it, and you burp to let that air out. In the same way, if you’re having a fizzy drink, the burp is again to let the air out. The air would generally be in your stomach or your oesophagus (the tube from your throat to your stomach).
      The noise you make is because of the air up your oesophagus and making bits of it vibrate.
