Piano tuning peg capable of being accurately adjusted

Abstract

The invention discloses a piano tuning peg capable of being accurately adjusted. The piano tuning peg is used for solving the problem that tuning peg tuning in the prior art is inaccurate and the tuning peg can only be adjusted by experience. The piano tuning peg structurally comprises a shaft rod, a force bearing slide block and a slide block, wherein the shaft rod is a hollow pipe, the slide block is located in the shaft rod, and the slide block is used for fixing one end of a string; the shaft rod is further provided with the force bearing slide block under the pulling force of string, thestring penetrate out of a string hole of the force bearing slide block instead of directly extending out of the slide block, a screw rod is further arranged in the shaft rod, the screw rod is connected with internal threads of the rod head part, and the position of the slide block in the screw rod is changed through rotation, and then the tightness state of the string is changed. The strings are installed in a mode that the strings are firstly fixed in the end pipes, then, sequentially pass through the movement grooves, the arc faces, the movable grooves, the string holes and the arc plates, and finally, extend out of the string holes, so that the strings are completed.

Description

technical field [0001] The invention belongs to the field of pianos, and in particular relates to a precisely adjusted piano peg. Background technique [0002] Piano pegs are used to stabilize the strings and adjust (pitch) the tone - metal pins inserted into the peg block of the piano, which are turned to raise or lower the tension on the strings to achieve a certain pitch, the The "sound" of a tight string becomes higher, and the "sound" of a loose string becomes lower. Generally, the tension of a steel string of a piano reaches about 90 kilograms, so the peg board must use strong friction to hold the peg tightly to prevent the string from loosening; it is precisely because of the above reasons that the piano tuner is adjusting the piano. In the temperament, it is necessary to overcome the friction between the peg and the peg board and the tension of the string, and carefully adjust the tune up (tighten) and down (loosen) according to the ear of the tuner, relying on hear...

AI Technical Summary

Problems solved by technology

Due to the existence of many factors, the uncertainty of each action is conceivable; in addition, what is even more unacceptable is that the "tone" you have worked so hard to adjust, as time goes by, Climate change plus factors such as the tension of the strings on the peg, all the "sounds" will gradually become (loose) and low, which is also the most fatal flaw brought by the peg in the manufacture and use of traditional pianos

[0003] Due to the above reasons, the difficulty of tuning the piano and the difficulty of keeping the sound accurate have greatly increased its hidden costs in the process of manufacture and use.
