It's a common misperception that the body of the guitar vibrates to create the sound. Actually it the column of sound around the guitar and in the guitar which vibrates to create the sound. When you vibrate the strings, the air around it vibrates causing the air in the guitar to vibrate.
Air particles vibrate and cause a chain reaction making the vibrations spread, which eventually reaches your ears and your ear drum vibrates, causing you to hear it.
