How to Make Piezoelectric Crystal Speaker

I make a loud speaker for a clock radio using a piezoelectric crystal. Actually I experiment with a variety of piezo crystals. That includes a piezoelectric igniter crystal from a BBQ lighter and a homemade/DIY rochelle salt piezoelectric crystal. I also try out a piezo buzzer from Radio Shack and also a crystal earpiece normally used with a crystal radio. To increase the voltage coming from the radio I first try stepping it up using a doorbell transformer and then I use a microwave oven transformer.
