Embodiment Construction

[0021] A piano tuning enthusiast who has tuning experience uses a semi-automatic piano tuner based on electronic labels to tune his own KAWAI K-3 piano. The sound pickup and detection part adopts computer software system. The electronic tag uses an anti-metal electronic tag. The content of this adjustment is to adjust the middle C tone (its standard pitch value is 440hz). First, the hand-held card reader is close to the string code. With different positions, the handheld card reader will display the key numbers and standard audio values ​​corresponding to different string codes. , near the central position, the card reader displays "C4440hz", this string code is the C4 middle C note to be adjusted, and the octagonal piano wrench head of 1 is inserted on the first string code above. Through listening and testing, the actual measurement of 1# string is 437.7hz, the actual measurement of 2# string is 439.5hz, and the actual measurement of 3# string is 436.30hz. First, the 2 and...

Abstract

The invention discloses an electronic label-based programmable control semi-automatic guide rail-type piano tuner. The piano tuner comprises a motor, a planetary speed reducer, a power transfer mechanism of a turbine worm mechanism, a controller, an electronic label and a guide rail-type piano tuning mechanism, wherein the power transfer mechanism is fixed on the guide rail-type piano tuning mechanism; and the electronic label is annularly stuck on the saddle of the piano. The tuning method of the invention comprises the following steps: an electronic label module of the controller reads a frequency set by the saddle to be tuned; a pickup reads the saddle to be tuned to obtain a software measurement frequency; and the frequency difference is converted into a certain step length drive amount by an algorithm of a central processing unit of the controller to send an instruction to the power transfer mechanism so as to finish semi-automatic tuning of the saddle and gradual tuning of the saddle of the piano, wherein the step length can be flexibly adjusted according to precision and experience. The invention saves manual tuning and is a high-precision special tuning tool for professional tuners and tuning lovers.

Description

technical field [0001] The invention relates to the technical field of pianos and musical instruments with pegs. An electronic label-based semi-automatic piano tuner is a professional tuning tool composed of a programmable servo mechanism, a programmable controller, an electronic label and a rail-type piano tuning mechanism. Background technique [0002] The shortcomings of the non-coaxial torsion design of the "L"-shaped tuning wrench used in traditional piano tuners began to attract widespread attention, and a large number of improvements have been made to this. However, most of the improvements have not gone beyond the limitation of manual operation, especially since there are so many string codes on the piano, it takes a lot of energy to memorize the frequency corresponding to the string codes, and it is easy to make mistakes. Therefore, the introduction of semi-automatic methods or even automatic methods is a major trend in piano tuning in the future, and through electr...
