ok so a while back i was asking about piezo buzzers for a specific application, but i realize know that it could never work. so keeping it simple, looking at loudspeakers
the project involves splitting a signal coming out of an electric guitar; 1 signal goes to the regular amp/speaker, the other part goes to what i'm trying to build. it's a board strung with many strings (essentially a zither) that are tuned to vibrate sympathetically with the guitar. since it's not physically connected to the guitar, there needs to be some element that vibrates the object. so after talking to some people and doing some research (this 'shaker' exists commercially, it's just expensive), i supposedly can de-cone a speaker, attach it to the board, and it will vibrate the board without producing significant sound by itself.
so i'm looking for a small speaker (3-5" would be best) that has good power and can reproduce the range of a guitar well. now i'm not worried about the sound quality of the speaker, since the cone will be out and it shouldn't make too much noise. it should vibrate at least as much as the top of an acoustic guitar when strummed, but more would be better. i don't need any tone/level controls for this speaker, just a volume.
can someone recommend me an inexpensive speaker and show me a circuit that goes along with it? something that runs on batteries would be best if possible, i don't know anything about circuits that are powered by wall outlets.
