Sound is produced when something is made to vibrate.

The strings of a violin produce a sound when they are plucked.   

  The vibrating strings make the air and the material of the violin vibrate and allow the sound to be heard. 
If the prongs of a tuning fork are hit, they produce a sound.   

  The prongs vibrate and a faint sound can be heard. If the handle is placed on a wooden board, this vibrates too and the sound increases. 
If the skin of a drum is struck it makes a sound.   

  The drum skin vibrates, as does the drum material and the sound can be heard.
