What's the difference between an electronic piano and a piano?

1, the sound principle is different: the piano is produced mechanically. Pressing the keys on the keyboard will affect the mallet wrapped in felt inside the piano, and then hit the steel string to make a sound; The electric piano is an electronic sound generator, which uses the keyboard as an on-off switch to form electrophoresis. Once the key is pressed, the internal crystal oscillator starts to work, forming a pulse to generate a waveform with a certain frequency, which is then amplified by the frequency divider and sent to the speaker for sound generation.

2. Different shapes and structures: pianos are mainly divided into upright pianos and grand piano in appearance, covering a wide area; The electric piano is similar to a rectangle and takes up less space.

3, the weight is different: the piano sounds mechanically, the structure is relatively complex, and more materials are needed, while the electric piano uses electronic sounds, which simplifies the complicated and saves a lot of materials; So the piano is much bigger and heavier than the electric piano. Ordinary pianos are generally around 200 kilograms, while electric pianos are only about dozens of kilograms (generally only twenty or thirty kilograms), which is very different.

4. Different portability: Due to different weights, electric pianos and pianos have different portability, so electric pianos are easier to carry.

5. Different functions: Both the piano and the electric piano have 88 standard keys, but the electric piano not only has 88 standard keys, but also has the function of an electronic organ and even a synthesizer, and there are many timbres and rhythms to choose from.
