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.¹⁾ 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.
