When using a keyboard instrument, instead of directly hitting the strings of the instrument to produce vibration, the keys are used to produce sound through the mechanical mechanism or electronic components in the instrument. Compared with other musical instrument families, it has incomparable advantages, which is its wide range and the ability to produce multiple musical notes at the same time. Because of this, keyboard instruments, even as solo instruments, also have rich harmony effects and orchestral colors. Therefore, since ancient times, keyboard instruments have attracted the attention and love of composers and music lovers.

The "electric piano" discussed by people today is a branch of the electronic piano family. Strictly speaking, it should be called "digital piano". People in Taiwan call it "digital piano". In the 21st century, "digital piano" has been called "electric piano" by convention. Its sound principle is that the integrated circuit converts the corresponding sampling signal through the calculation of physical conditions such as key strength, pedal application and key speed, and then emits different sounds after certain calculation. All instruments that use digital sampling technology and simulate piano timbre belong to this category. Generally, the principle of the induction key force of the electric piano is: two induction contacts are placed under the keys, and the keystroke speed is determined by calculating the time difference between pressing the upper induction point and the lower induction point.
