Are there any alternatives to piezo transducers when building an electronic drum?? Answered

I'm trying to build an electronic drum, but piezo transducers seem to be rare in my country !!!! so I'm wondering if there's an alternative to them.


Microphones pointed at the striking surface, feeding a pulse-detection circuit which triggers the drum sound, would work. You'd have more problems with crosstalk (hitting one drum triggering another), and of course there's the balance between making the drum's noise loud enough to pick up but not so loud that it's noticeable over the electronic sound, but it can be done with appropriate microphone type/placement and pad design. The circuitry gets more complicated if you want the force of the strike to affect the volume/characteristics of the sound, but that's true of the piezo approach too.

You also may want to look for "contact microphones", which is essentially what piezo transducers are one example of.

Of course, anything that acts as a switch will work if you don't insist on the force of the strike making a difference -- including drumming on metal surfaces with wired drumsticks.

You can get piezos cheaply on ebay, ur country should be no obstacle....................

I have piezo material (barium titanate)BaTiO 3 for sale on ebay.Look up slowrowboat.I sell it by the 1/4 pound for $10.00 and i will ship anywhere in the world.

You can make your own triggers or buy them, different brands are of course different prices Pintech, Ddrum and Pulse have them with or without traps (traps hold the trigger in place on the drum lugs) I don't really know how well Pulse and Ddrum work but I am pretty sure that in this case price doesn't necessarily mean better quality of the internal components (the piezo itself and the wire connections) a decent set of triggers 5 total 4 toms, snare and bass drum, should go from about $ 150 to 250 depending on how fancy you want to get, or you can buy the cheapest ones without traps and just follow my tutorial on how to make your own for little to no money if you have aluminum scraps laying around.

Not really, the "transducers" can be made from piezo sounders - which you can find in all kinds of electronic things- even kids toys.
