The present invention relates to an electronic piano capable of rolling up a keyboard. A roll-up electronic piano according to the present invention comprises a keyboard including piezoelectric material and a control part with a sound chip, which controls and amplifies electrical piezoelectric signals. The roll-up electronic piano has a foldable and unfoldable keyboard and is easy to carry due to ultra-light weight and small size. Particularly, the roll-up electronic piano produces a similar tone to that of a real piano. Therefore, the rollup electronic piano can be conveniently used in music classes and enhance the efficiency of learning. In addition, the roll-up electronic piano can be played anywhere without being restricted by space and can be controlled by a wireless method after the keyboard is separated from the control part. |
