Often this is done by an electrical current that creates a magnetic field which causes a physical movement. 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.
