An electromechanical component is one that uses an electrical signal to cause some kind of mechanical change, such as a motor turning. Often this is done by an electrical current that creates a magnetic field which causes a physical movement.((http://www.penguintutor.com/electronics/reference-electromechanical)) Electromechanical musical instruments are ones that use electricity to move parts that generate an acoustic sound. This does not include instruments that use a more complex processing of electricity such as speakers, modulators, or synthesizers. Examples can include hammers that strike based off an electric signal or wheels that spin when activated. A prime example of a commonly used electromechanical tool is the stepper motor.\\

===NOTES===
Not included in the discussion is the use of piezo transducers and electric pickups. Though Piezo Transducers can be used as a speaker element, they are more commonly use as a microphone element and much like electric pickups, don't represent the sound generating method. \\
When used as a sound generator Piezo Transducers are part of an electric or electronic musical instrument. \\
