shielding piezo transducer (contact mic)

Post by vnmb » Wed May 09, 2018 1:06 pm

I have been having problems with a contact mic i bought online for awhile, it makes a ground loop whenever it is plugged in. I bought a BEHRINGER MICROHD HD400 to try to get rid of the ground loop it but it did not work. I think the problem is the contact mic, but I might not be able to fix it because I bought it premade online like I said and it is epoxy'd to the bottom of a soda can. But does anyone know how I can build a contact mic that doesn't buzz or try to fix the one I have?

what type of premade piezo microphone?
you could always pop it open and replace the "disk"
then super glue it back together
check wiring on the plug and the disk
it was probably "abused"
hard saying without actually inspecting
you can restore it with easy swap out of disk
hardest thing is getting in the plastic casing

they are so beyond super simple making
same as drum triggers
grab some piezo elements from ebay then wire em up for cable
get creative making some type of housing with 3.5mm or 1/4" jacks
