I demonstrate a transducer I made from an old speaker by removing the cone and frame. That exposes the dust cap, which can then be brought into physical contact with an object. With a contact microphone attached to the object, and the (guitar-) amplified signal sent to the transducer, feedback is induced through the object, stimulating its various vibrational modes to remarkable effect.
