Description

Technical Field

[0002] The piano is a keyboard instrument, mainly composed of keys (including white keys and black keys) and a metal string soundboard. The keys are used to pull the hammers to hit the strings to produce sound. The piano has a wide range of tones, almost covering all the musical sounds in the musical system. It is one of the instruments with the widest range of tones and is commonly used for solo, duet and accompaniment. The electronic piano, also known as the electronic piano, is an instrument that uses digital electronic technology to simulate the sound of a real piano. Its sound-generating principle is to use the keyboard as an on-off switch to form an electric pulse. Once the key is pressed, the internal crystal oscillator starts to work, forming a pulse to generate a waveform of a certain frequency, which is then amplified by the crossover and sent to the speaker to produce sound. With the development of technology, the sound-generating principle of modern electric pianos has become more complex, and can simulate more realistic and rich timbre and resonance effects.
