hi I found this forum on the net... . figured Id give it a try.
I'm a musician/audio guy working on a quirky project. my goal is to turn normal objects into speakers by painting them with some magnetic paint I found at my local art store. The other end of this, however, requires that I build a fixed electromagnet capable of handling an audio signal (presumably from an amp) and also capable of moving the object. (my first target is the base of a metal wash bin)
so far...
using magnet wire and a nail seems to yield sub par results. the insulation melts and smokes within 5 minutes and the magnet is rendered useless. the sound is also very distorted. it sounds as if there is a rectifier of some sort on the signal. it is also heavily weighted toward bass (which is ok and to be expected... hell its not like the bottom of a washboard is a paper cone)
whats the trick to converting electric audio signals to magnetic signals?
thanks for your time
matt
