Electronic piano

An electronic piano is a keyboard instrument designed to simulate the timbre of a piano (and sometimes a harpsichord or an organ) using analog circuitry.
Electronic Piano was also the trade name used for Wurlitzer's popular line of electric pianos, which were produced from the 1950s to the 1980s, although this was not actually what is now commonly known as an electronic piano. Electronic pianos work similarly to analog synthesizers in that they generate their tones through oscillators, whereas electric pianos are mechanical, their sound being electrified by a pickup and then amplified through an internal or external amplifier.
