Questions & Answers

Can you tell me how their frequency response is?

These devices are piezoelectric, so they activate by pressing, touching, or hitting, and you have to use 2222 or another piece if you want the signal to be amplified

Which disc is thicker, the paper or the plastic?

In the neighborhood of A 34mm diameter.

There must be a tiny noise generator out there. What would happen if I applied 3 Is 5Vdc enough to cause the buzzer to work?

You need to create an electronic circuit so that when you touch or hit it, it will send a voltage. You need to catch this voltage and do what you want with it.

If they are forced to be slightly curved (under the bridge of a stringed instrument, for example), can they still be used as contact microphones?

This was a fantastic pick up for drum pads and withstood a great deal better than I I am sure they can still work great even if they bend a little.

Selected User Reviews For 20 Pieces 20mm Dia Film Gasket Piezo Ceramic Disc Piezoelectric Buzzer

Transducers of great quality! They are GREAT for musical instruments

5/5

IMPORTANT Never use them for wireless systems. There is no preapproval for these Wires are connected to transducers by soldering, so you need to know how to do this properly without damaging them. I've found that once soldered, these produce the best sound among all the plugs I've tested. In reality, I have no idea why these work so well, and your mileage may vary, but I will be using these for all future custom pickups.

The DIY value is exceptional

5/5

In terms of value, you get a lot for your money. It took me a little longer to get the solder to stay, but that was more my fault. I would choose the discs with wires already soldered if I were to buy more. There is no downside to this deal if you don't have any difficulty soldering.
