A project log for PCB Speaker

Open Source Speaker made from a PCB

If you are following my pcb actuator projects you have probably noticed that they beep when placed near a magnet. This is because I am driving them with a frequency that is in the hearing range. 

It sounds like a very weak buzzer. This is because a speaker is basically made from a coil that actuates a magnet to move air.

So how, can I improve it and make it sound better to build the first speaker made from a PCB?
