I've bought an atomizer circuit and "speaker", which appears to want a water depth of 1cm. However the tank/valve I have produces 2cm depth. Is there a way to change the electronics to make it vibrate water into vapour at a greater depth?

This is 25W, a 1 inch transducer. The same as the thing I replaced. But it refuses to atomize through that depth of water. The old one did (although it did burn out after 9 months). How do you suggest I increase the power? And should I be looking at a higher power or a higher frequency?
Are you sure the transducer isn't focused?
Cheers

I have no idea how that would work. There's nothing special about it that I can see, just a 1 inch metal transducer. Similar circuit powering it as the original humidifier. It's this:

May be wrong frequency, I see they have 2.4MHz and 105Khz drivers.
"They" as in the seller? I can't see those. Which one do I have and where do I get the other?
So, you wanted to nudge me into not using what I was asking about how to make work. Not very helpful are you?
And it's spelled behaviour, with a U. American isn't a language.
And you're the one that edited my subject to some bollocks or other. I'm guessing you're a troll and I should engage my killfile?
Remind us, who was the idiot who posted to non-uk newsgroups?
The only troll here is one who's too lazy to work and seeks attention.
What's wrong with posting to non-uk newsgroups? Do you think US citizens don't use humidifiers?
Too ill to work.
It is only wrong if you criticise spelling indigenous to another country.
That is what lazy people claim.

Increase the amplitude of the exitation signal, dippity doo dah.

I made an HV supply that was used to excite a ring with a pin protruding up through it. A hollow pin... a 'jet' as it were.
And when a non-conductive thin liquid is introduced, it turns into a 'perfect smoke' by making all the molecules repel each other. They cured some TB forms with it because it makes the drug actually make it to the target flesh instead of simply becoming a mist against the back of the throat.
15kV with all the conforming specs for medical devices with human contact. microamp curren shutdown and nearly instant. Took a couple years to develop and you could fit 6 of them in a cigarette pack (100mm). It even had a vacuum potted box on the mutiplier end. It ran from about 4.5 volts up past 9 volts. and had a four segment HV transformer before the multiplier that had about 1000 turns of #54 on each segment. Short of not being able to do much work like say fire an X-ray tube, it was one of the most precise, most complicated supplies I developed.Phil Hobbs snipped-for-privacy@electrooptical.net wrote in news: snipped-for-privacy@electrooptical.net:
Are not piezo wafers all quite flat?
It could be frequency tuned to respond best at a specific depth.

Are you really so stupid that you cannot grasp that he was referring to your inane Us English remark?
It is a rhetorical question. I am sure you are just a f****ng joy to those other groups' readers as well.
Focused transducers are pretty common in applications--dunno if they're used in super low-end stuff like vapourizers.
Cranking up the power doesn't help so much if you're just causing cavitation at a submerged acoustic focus.

Yes, he's not that bright. Most people killfile him.
His genuine name isn't Peter Hucker for nothing.
The language is English, it's only indigenous to England.
Just because the "science" we call medicine can't name and cure a disease doesn't mean it doesn't exist.

I also made a Piezo stack stimulator amplifier which was 2kW and was
20Hz to 20kHz range. The output included a HUGE coil in a huge ferrite core pair. Those were fun to wind. It had an 18 inch long heat sink for the row of drivers it had on it. Have to mount them all, and THEN solder the heavy legs to keep it all coplanar to the sink. It also had two 2kVA transformers sitting in the bottom of the cabinet.It drove a stack of Piezo chips about 30mm in diameter and a hundred tall (4 inches) for a total deflection of just over one millimeter, which we doubled with a 2:1 rocker arm which drove a presicion lathe cutting tool. That coupled with a feedback loop on the lathe allowed for optical quality surfaces and it was used to cut perfect 'molds' for 1 inch diameter contact lenses for race horses.
That was a fun development.

Sounds like it could be used to prevent cavitation on propellers for subs. Shame though that it is acoustic. Like raising a flag (or firing up a boom box) saying "Here I am!"
