OK,
In our work shop we have this tuning fork mounted on a mini soundboard.
If you just strike the tuning fork with 'something' you will hear it 
vibrate, but actually not very much.

If however you put the mini sound board under pressure by bending it 
with your muscle power, the tone increases and becomes noticeably 
louder.
In other words : if you apply pressure on the soundboard by bending it, 
the tuning fork vibrations get louder.

Why?
