Background
Piano element has a name of 'king of musical instrument', which is composed of 88 keys (52 white keys, 36 black keys) and a metal string soundboard, invented by Butooro-Crisdori, Italy in 1709. The piano range is from a2 (27.5 Hz) to c5 (4186 Hz), and almost covers all tones in the tone system, and is the instrument with the widest range except for the organs. The piano is commonly used for solo, repetition, accompaniment and other performances, and is very convenient for composing music and rehearsing music. The player drives a small mallet covered with a felt in the piano by pressing keys on the keyboard, and then strikes the steel wire strings to make sound. However, since the piano is difficult to be accepted by ordinary households due to high cost and high maintenance difficulty, the electric piano has been developed in the sixties and seventies of the twentieth century. The sound production principle of the electric piano is that a keyboard is used as an on-off switch to form electrophoresis, once a key is pressed down, an internal crystal oscillator starts to work to form a pulse to generate a waveform with a certain frequency, and then the waveform is amplified by a frequency divider and sent to a loudspeaker to produce sound.
Although the electric piano is increasingly popular with mass music enthusiasts due to small volume, portability and low cost, a piano teacher needs to carry an electric piano support or prepare a shelf for placing the electric piano in advance when teaching students, so that the students can conveniently teach music, and especially the piano teacher needs to carry a seat when teaching outdoors, which brings great inconvenience to the electric piano teacher.
