piezo speaker max. voltage

[Bernhard Kuemel]

Hi sec!

What's the maximum useful voltage a piezo speaker can take? I thought of
putting it in parallel to a Geiger Mueller tube or an Ne-2 bulb as an
improvised geiger counter.

The piezo speakers I have are salvaged from other devices so I have no
data sheets. Looking at other datasheets the maximum specified voltage
was 30 V. I have created about 50 V by flexing a piezo speaker, though.
One datasheet specified "DC Voltage Not to be applied between
electrodes"[1]. I'd be having 80+ V DC.

Thanks, Bernhard

Think! What are coupling capacitors for?
