DIY Triangular Balanced Contact Microphone Sonigon
Step 3: Building. The idea was to use the lid as a cover for the sensitive piezo disc. So the first thing I did was to hot glue cardboard inside the lid to make the piezo disc able to lay flat against any surface I attach it to. Next I reinforced the solder joints with hot glue and striped the microphone cable and tined the wires.

Contact mics can be used to sense unusual sounds when attached to various surfaces.It also Produce sound when voltage is applied to it.With the help of a basic Pre-amp circuit it can also be used to Electrify an Acoustic Guitar, where amplification is a must.

Building your own contact mics is a great project to try as they are cheap and straightforward to make, with very little soldering, and not much to go wrong! Contact mics can produce great results, and are useful for recording things in isolation with out any background noise. Rather than record sound in air, they capture the vibration and resonance of the object they're in contact with.

Assembling Your DIY Contact Microphone. Follow these steps to assemble your contact microphone: a. Strip the ends of the shielded audio cable, exposing the inner wires. b. Solder one end of the audio cable to the piezo transducer, connecting the signal wire to the metal surface of the transducer and the ground wire to the outer edge.

Step 2: Schematic. This circuit uses a low pass filter to output sounds from the piezoelectric sensor (or contact microphone). The potentiometer is used as a variable resistor so that when you turn the dial you change what the filter is filtering. The potentiometer only has the middle pin and one of the outer pins connected to the device.

December 20th, 2011 It's amazing what a little disk can do. when it's layered with piezoelectric crystals. Piezo disks are impressively sensitive to vibration and can easily be adapted to work as a contact microphones. The trick is the preamp - a basic circuit used to match the piezo's signal to levels compatible with modern audio gear inputs.

Air pressure microphones are implemented in various applications and are recorded by many types of devices so usually they are made fairly easy to drive and produce mic level signals between -30 and - 60 db at a voltage roughly at 2.5 millivolts. Contact microphones on the other hand are not really designed for recording high end audio.
