Electromechanical Oscillator

The Electromechanical Oscillator uses modified loudspeakers and small motors as electromechanical transducer elements to mechanically excite and elicit sound from suspended metallic objects. The sound produced by the objects is picked up by piezoelectric contact microphones, amplified and output to standard loudspeakers as well as being fed back to the input of the modified loudspeakers and motors. Where the signal from a resonating object is fed back to the electromechanical device that is exciting that same object, the result is a continuous electromechanical oscillation.

Within this system the objects make their own mysterious and emergent composition.
