A piano notation system

Abstract

The invention belongs to the technical field of musical instruments, and relates to a piano score flipping system. The system solves the problems that an existing music turning device affects the piano tone quality, and damages a music score. The piano score flipping system comprises a music stand, a paper sucking unit and a paper pushing unit; the music stand comprises a bottom plate and a panel,the paper sucking unit comprises a sleeve and a piston, the sleeve is arranged on the panel, the sleeve is provided with a vent hole, the inner end of the piston is inserted into the sleeve, the outer end of the piston is connected with a paper sucking pull cable, a paper sucking pedal capable of driving the paper sucking pull cable to move is arranged at the bottom of a piano, the paper pushingunit comprises a paper pushing pedal and a paper pushing pull cable, the paper pushing pedal is arranged at the bottom of the piano, the lower end of the paper pushing pull cable is connected with thepaper pushing pedal, a swing rod is connected to the upper end of the paper pushing pull cable, the upper end of the swing rod is hinged to the panel, moreover, the reset mechanism is arranged between the swing rod and the panel, and the lower end of the swing rod can swing to the position above the music score on the panel. The piano score flipping system has a small influence on the piano tonequality and does not damage the music score.

Description

technical field [0001] The invention belongs to the technical field of musical instruments, and relates to a piano sheet-turning system. Background technique [0002] With the continuous popularization of the piano, more and more people learn the piano, and when playing the piano, the problem of turning the score has always existed. Whether playing the piano or performing other musical instruments, musicians' hands are always busy playing, and there is no free hand to turn over the score. For example, when playing the piano, the pianist has to stop and reach out to turn the page in order to see the staff on the next page after finishing playing a whole page of music, which interrupts the rhythm of playing the music. In this way, The music cannot be played smoothly. [0003] In order to solve the above problems, Chinese patent CN 102815116 B discloses an automatic sheet-turning device for pianos, which includes a bottom plate, a paper pickup mechanism, a paper pickup shaft ...

AI Technical Summary

Problems solved by technology

[0004] Although the automatic page-turning device disclosed in the above-mentioned patent can realize the page-turning of the music score, there are still the following defects: 1. In the above-mentioned device, a motor is used as the driving source, and as we all know, when the piano is played, the extra high-frequency vibration It will affect the sound quality of the piano, and when the motor rotates at high speed to drive the gears to rotate, it will inevitably affect the playing of the piano, and the rotation of the motor depends on the power supply. It is necessary to install a battery on the piano or have an external power supply. 2. The above-mentioned device rubs the sheet music paper through the paper pickup wheel. If the force is small in this process, the paper will not be rubbed up. If the force is large, the sheet music will be easily broken. Moreover, for the sheet music paper with a smooth surface, the friction between the pickup roller and the paper is small, so it is impossible to pick up the paper

In summary, the above-mentioned page-turning device still has major problems in actual use, and cannot be practically popularized and used.
