I've always thought that transducers were another name for pickups, and doing
an internet search that seems to be what they are. They convert an acoustic
vibration into an electrical signal. But when reading about the old Ondes
Martenot keyboard instrument, they say that one of the speakers (or diffusers)
uses a transducer to drive the strings on one of these diffusers. Is there a
device that I can use that takes an electronic signal and converts it into an
acoustic vibration for setting a string in motion or driving the bridge of an
acoustic instrument? Something other than a speaker that is. I'm still thinking
about setting a violin in motion using a synthesizer.
