the coils are positioned at around one third of the strings length. there is no DC, and i am driving them with a dual ended amplifier. the output is definitely clipping, which is probably a big part of my problem. a couple of thoughts : would a larger core with the same amount of wire (same...

more efficient use of the energy I'm outputting through the coils is really what I'm trying to do, although the volume could be slightly better as well (volume is still not a chief concern!) attaching a piece of magnetic material to the string will distort the resulting sound, and increase...

the circuit that drives the string automatically tunes itself to the strings fundamental frequency - so the driver frequency is not fixed, but dynamic. the volume builds up from nothing in about 200 ms.

the electromagnets actually output a consistent alternating current that matches the fundamental frequency of each string. each individual string never touches it's electromagnet core, but swings pretty close to them... the strings i use are for electric guitars, hence ferromagnetic!

Hello everyone, For the past 4 years I have been working on a new type of musical instrument that fuses together elements from electronic music into the acoustic realm. The instrument consists of 26 strings inside a wooden enclosure that are actuated (or "bowed") by the use of electromagnets...
