Sourcing ultrasonic "fogger" transducers

[R Speir]

I would like to build an ultrasonic fog generator (humidifier,
nebulizer, mister, whatever you want to call it) for fun. I know I can
buy one preassembled from any pet store, but that would eliminate the
challenge and DIY aspect of the project. Problem is, I'm having
trouble actually finding any transducers that. In fact, the actual
part numbers and manufacturers have proven terribly elusive. TDK
apparently manufactures a few piezo nebulizer parts, but I haven't been
able to locate a vendor that sells them.

I'm just wondering if anyone here knows where a hobbyist could order
(or sample) a small quantity of 1-2 MHz high power piezo transducers
that would be capable of producing fog when placed under a few cm of
water, or could at least point me towards a product line/serial
number/manufacturer that I could seach for. Thank you in advance for
any help.

Look online for the multiple-disk units. They sell spares.

Are the spare disks they sell actual piezo elements? In all the photos
I've seen, the disks don't have any leads attached, so I assumed they
simply sat on top of the piezo element and transmitted ultrasonic
frequencies to the water.

If you're in North America, and maybe other developed countries, the
easiest source would ironically be commercial generators. You can
easily find humidifiers at garage sales and rummage sales, and even
if you want to build one, they may be the easiest and cheapest means
of getting the transducer.

Dear Friend:

Maybe you can source this from China. However I am now selling various
kinds of quartz crystal products including quartz crystal resonators,
crystal clock oscillators, monolithic crystal filters, XO, VCXO, TCXO
and VC-TCXO, which are wildly used in communication equipment, AV
equipment, OA equipment, measuring instruments and various types of
clocks.

Our company employs about 600 staff, including more than 70 engineers.
All workers must pass the special training before post arrangement. In
order to ensure the dependability of our products, we built a
super-clean workshop. We are also backed by strong technical strength.
We can specially provide crystal testing and crystal application
circuit analysis services to our customers. Our factory is ISO 9001,
ISO 9002 accredited; this allows us to guarantee an undeniable and
undisputed quality level, and our products have passed RoHS testing,
SGS testing.

With 14 years' experience and expertise in this field, we can offer
your total solutions and customize your required specifications.
We are looking forward to cooperating with more friends from all over
the world.

Please kindly response if there are friends just fall into this fields,
I will try best for you.

Warm regards,
Sincerely
Tim

maplin electronics sell them for £2.99 last time i looked here in the uk
they are the transducer they connect through a spring and earthed through
the metal can

Piezo transducers as a rule consist of a metal disk with the quartz
bonded to one side, and a metal electrode vapor-deposited on the bare
side of the quartz. One side of the signal goes to the metal disk, one
side goes to the metal electrode. In many applications, there are no
wires soldered to the disk at all; connection is made through springy
contacts of one kind or another.
