spanac,

I am sure you mean peizo instead of buzzer. Because buzzer makes
only bzzzz sound no thing else and it needs dc voltage only but
peizo is a capacitor. you can use it as microphone to sense
impact "shock sensors, drum pads etc. To answer your question
yes you can use it as speaker but you need to add resistor on it but
it is going to be very low output. This is once of the reason pulse or 
play melody is better choice.

Subject: [EE] How is a buzzer different from a regular speaker


Hi guys,
i want to use a buzzer instead of a simple speaker
to play some voices or even some short musical
fragments.
Is this doable ? I searched on google for simple tests
or examples but i could not find any though i was able
to find some projects using buzzers for simple sounds.
I just want to know if what i want is possible and if
it is much harder to implement than with a simple speaker.

Thanks in advance,
spanac
