Electronic piano with adjustable hand feeling

Abstract

The invention discloses an electronic piano with the adjustable hand feeling. The electronic piano comprises a base shell, a piano key base, keys and a heavy hammer. The base shell is divided into a plurality of sections in the length direction. The sections are hinged in sequence. The piano key base is correspondingly fixed in the base shell. Key positioning shaft bases, a key extension area, a heavy hammer area and a positioning area are arranged on the piano key base. A plurality of fixed bases are arranged on the heavy hammer area. A first rotating shaft penetrates through a heavy hammer moment origin through hole to rotationally connect the heavy hammer to the fixed bases. A plurality of key positioning shaft bases are uniformly arranged on the key base. A second rotating shaft penetrates through a through hole to rotatably connect the keys to the key positioning shaft bases. Clamping holes are formed in the lower end faces of the keys, one ends of the heavy hammers are clamped inthe clamping holes. Adjusting heavy blocks capable of adjusting the fixing positions are arranged at the other ends of the heavy hammers. A plurality of groups of LED indicating lamps in one-to-one correspondence with the keys are arranged below the keys. The electronic piano can be folded. The torque of a counter weight can be adjusted. The playing hand feeling of the electronic piano is better.Meanwhile, the functions of indication, teaching and guiding can be achieved.

Description

technical field [0001] The invention relates to the field of electric pianos, in particular to an adjustable electronic piano. Background technique [0002] The electric piano is an electro-acoustic musical instrument. It emerged in the 1960s and 1970s and became popular in the 1980s and early 1990s. It is used to replace the piano in some occasions. The sounding principle of the electric piano is The keyboard is used 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 of a certain frequency, which is then amplified by the frequency divider and sent to the speaker to produce sound. [0003] Because it does not need to be tuned, the rhythm and tone are selective, and the outer and inner tones can be switched, and the price is cheaper than traditional pianos, so it has been sought after by more and more music lovers in recent years. However, when the black and white keys o...
