Microphone to create Oscillations to make Piezoelectric Disc Create Sound?

I'm a student at UCL and Im trying to use an electret microphone to pick up an audio signal which is then reproduced by a piezoelectric disc as a part of an experiment with sound perception in spaces and materiality.

Ive tried crudely including the mic in a circuit of a piezo buzzer and the best I get is the sound of my voice through the buzzing but what I'd essentially like to do is have the piezo recreate the sound that comes from the microphone. There are many forums that show how to turn a piezoelectric disc into a speaker for your ipod or computer but I havent been able to utilise these.

If anyone could help or share a little bit of light on the situation for my I'd be so so greatful.bq).

Hi Akil,

Check out this Turn nearly anything Piezo into a Speaker .

Hope it helps

Cheap piezo devices, used in buzzers, are noisy, and have nasty resonant frequencies.
They will probably not, without a lot of effort, reproduce pick up from your microphone. There are companies producing piezo speakers for audio reproduction, they however, still have limited band width in comparison to a conventional speaker, but are good enough for speech. The driver amplifier must be able to drive a purely capacitive load, and may require a higher voltage than one designed for a resistive speaker load. Check out the web for more info, Sonitron popped up (I have no connection with them) have data for their devices, compare that against data for a piezo buzzer,
cheers,
Richard

For the nature of your experiment, an ordinary small audio amp and speaker will probably be easier to use.
