Magnetic piano keyboard assembly

Abstract

The invention provides a magnetic piano keyboard assembly. The magnetic piano keyboard assembly comprises a piano stand, a piano stand fixing base, iron blocks, a magnet, a magnet sleeve, piano keys, a rotation shaft, a key board, pressure columns and silicon keys, wherein the piano keys comprise white keys and black keys arranged side by side; two ends of the piano stand and the piano keys are arranged to be a C end and a D end; the magnet sleeve is arranged on the piano stand and is positioned at the C end, the magnet is arranged inside the magnet sleeve, the iron blocks are arranged on the piano keys and positioned at the C end of the piano keys, and the iron blocks are positioned just above the magnet; the piano keys are rotatably arranged on the key board through the rotation shaft and form a lever strucutre; the upper ends of the pressure columns are arranged in the middles of the piano keys, and the lower ends of the pressure columns lean against the upper surfaces of the silicon keys; and the silicon keys are arranged in the middles of the key board. According to the technical scheme, the piano assembly is light in integral weight, the very good key effect and feeling that a heavy hammer knocks a keyboard are achieved, the effect of knocking the piano keys with the force gradually reduced is achieved, the resetting effect of the piano keys is good, and the resetting speed is high.

Description

technical field [0001] The invention relates to the field of piano equipment, in particular to a magnetic piano keyboard assembly. Background technique [0002] The electric piano is an electro-acoustic musical instrument. Because it does not need to be tuned, the rhythm and tone are selective, and the outer and inner tones can be switched each other, the price is cheaper than the traditional piano, so it has received more and more attention in recent years. However, the working principle of electric pianos is based on circuits and electrical devices, while the working principle of traditional pianos relies entirely on the mechanical action of mechanical structures to produce sound. In order to achieve the timbre of traditional pianos as much as possible, the existing Electric pianos use a counterweight mechanism to mimic the mechanical action of a traditional piano. [0003] Most of the existing electric piano counterweight mechanisms use a combination of counterweight fra...

AI Technical Summary

Problems solved by technology

[0003] Most of the existing electric piano counterweight mechanisms use a combination of counterweight frames and counterweights, and the counterweight frames and counterweights are all made of metal materials, resulting in a large weight of the electric piano and no percussion feeling ,
