The attached scribble shows a basic driver output stage I found for a piezo speaker (A).
Don't know much about this but why is it not as at circuit (B)?
(A) the output is ref'd to +V. If I want to refer the out to ground, would (B) do it? thanks

This NG doesnt do binaries / attachments.
Try uploading your schematic to a photo sharing site & post a link to it here.
Sure it does, I saw it. 245KB.
You still can't figure out that YOUR service provider's server setting is NOT what 99.9% of the rest of the world uses. Your pathetic "attachments" do NOT get past the first hand-off.
You are truly a clueless bastard.
I'm using Outlook Express and it came through fine. I saw 345KB. Mikek
It has nothing to do with the damned news reader, idiot!
Well I got zip, zilch, zero attachment here. I expect it got stripped on the way here.

Nope! SeaMonkey has no clue. Maybe it is the provider?
THen my server must be among those 0.10 % because I saw the image.

I sure hope you feel better. Mikek
They represent two cases of how the piezo device is driven; one without = DC bias and one with DC bias. I expect that these options reflect devices with slightly different mounting and electromechanical characteristics.
To choose the correct configuration for your driver you need to consult the datasheet.
