I won't copy and paste everybodies posts to keep from making a mess. I'll just
respond. Larry Hendrey missed the part where I said I wanted to remove a string
and in its place put some kind of device to vibrate the bridge. That would
vibrate at whatever pitch my synthesized waveform is. So matt_stubb and
groovshaman are correct in understanding what I wanted to do. I would need to
keep the other 3 strings there to firmly hold the bridge down, plus in all the
reading I've been doing about the violin, the body tone is a little different
when under the tension of all the strings than without any strings. Without
strings the main formants are lower in pitch.

When I thought of doing this a couple of years back I thought maybe I could
just screw a speaker into the back of a violin body. It's hard to tell if that
would give me any useful results or not. Based on what I've read, the bridge
acts like a lever and where it rests on the violin body and it's internal
structural supports determines where or how strong some of the main resonances
will be.

I'm looking at a small speaker now and there's the possibility if I cut off the
speaker cone I could use the transducer portion of the speaker to vibrate
something. I don't know how I'd mount it to the bridge, but maybe I could
compromise and remove the bridge and strings and mount it where the bridge was.
