Electro-acoustic instruments and devices
Electrical signals are passed to a loudspeaker to produce sound. The signals are produced using materials that generate acoustic sound, or by mechanically driven signal sources. Modules and configurations of acoustic, vibratory mechanisms (often resembling traditional acoustic instruments) and electronic circuitry such as transducers and amplifiers.
