What is the difference between an electric piano and a piano?

First of all, the classification is different:

Electric piano belongs to electro-acoustic instrument, while piano is a stringed instrument. In the 1960s and 1970s, the electric piano appeared, which replaced the piano in some occasions (the electric piano has a history of almost 65,438+000 years, so it can be said that the electric piano is based on its technology). Piano has a history of at least 300 years.

Second, the sound principle is different:

The sound principle of a piano is to press the keys on the piano keyboard, pull the hammer wrapped in felt in the piano, and then tap the steel wire strings (that is, strings) to make a sound! If it is not an instrument according to this sound principle, it can no longer be called a traditional piano.

The sound-producing principle of electric piano is to convert the collected sound into electronic digital signals on the basis of the sound sampling of original acoustic instruments, and then the sound is perceived by electronic components, which is essentially different from the traditional piano. After all, the timbre is different from the real piano, and it can't replace the traditional acoustic piano.

Third, the structural design is different.

Piano is mainly divided into upright piano and grand piano in appearance. Grand piano is the most primitive form of piano, which is now commonly used in concerts. Upright piano's strings are staggered, occupying a lot of space. Piano consists of string array, soundboard, bracket, keyboard system, pedal mechanism (including ejector pin and pedal) and shell.

The electric piano has a compact structure, which can not only adjust the volume, but also function as an earphone. The electric piano is similar to a rectangle and occupies a small space. Equipped with automatic accompaniment, metronome, digital effect, recording and playback functions.
