An electrophone is any musical instrument which produces sound primarily by electrical means. It is usually considered one of five main categories in the Hornbostel-Sachs scheme of musical instrument classification (though it is not actually present in the scheme published in 1914).
Any instrument which produces sound purely by electric means is an electrophone, but the term was not originally applied to instruments where electricity was only used to amplify a sound produced by conventional measures (so that the electric guitar, for example, would have been classified as a chordophone, not electrophone).
