Sourcing ultrasonic "fogger" transducers

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 Email: electronics2008(at)gmail(dot)com

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.
