Best way to stick a piezo transducer to a vibrating element?

amundsen · 16th June 2005

Hello,

I have built contact microphones with piezo transducers. However, I wonder what is the best way to stick the piezo transducer to the vibrating element so to have both a good recording and a long lifetime for the transducer. Should I use tape or should I use some kind of modelling clay? What kind of clay is shipped with commercial contact microphones?

Thank you for helping.

I opened the lid on an dirty old beat to crap grand piano to find a PZM glued with epoxy to the lid...

Gaffer tape fixes everything.

Rear-view mirror adhesive.

Or, cynalacrilate - crazy glue.

Either will be permanent, so choose your position carefully.

If you want a non-glue (non-permanent) solution, I have found Fun-Tak to work well on my drum triggers. Its a kind of blue putty that is used to put photos or posters on a wall instead of thumb tacks. It has plenty of holding power, but can be repositioned easily.
