The field have a frequancy in the MHz range. You can't hear at those 
frequancies, and the speakers are to heavy to react to them.
The field don't need to be very strong, maybe a few militeslas.
You already have magnetic induction kitchen ranges. Those with a glass like top 
that you can put your hand on immediately after you remove the pan, or raise the 
pan and leave your hand between the surface and the pan where you are cooking 
something.
