this stuff is relatively easy all you need is a soldering iron, some resin and get the parts at your local radio shlock

as opposed to a standard microphone which picks up sounds, a contact microphone more specifically picks up sounds by being connected to something/anything almost.

 

to give an example: if you attach a contact microphone to a piece of sheet metal and bow, bend and rub the metal or anything to the metal so that it creates some sort of sound, the contact microphone will amplify that sound when plugged into some sort of amplifier. Metal is a good object for a contact mic as it does a decent job at matching the frequencies being resonated thru the metal, however if a contact mic is attached to a piece of wood and the wood is struck you'll get a different sound and the frequency response is not as wide (which is somewhat expected because of the properties of wood vs. metal) but this is a dependent open the frequency response range of the piezo element of the contact microphone.

 

яка идея за тези които могат да сглобяват разни неща, и за експериментатори най-вече.
