Piano self-service tuning system

Abstract

The invention discloses a piano self-service tuning system, and the system employs a frequency value in a piano intonation curve which is automatically corrected through harmonic frequency as a tuningstandard of each tone, and employs the frequency, corresponding to a selected tuning note, in the corrected intonation curve as the tuning standard of an audio. The frequency comparison unit is usedfor comparing and calculating the actual fundamental frequency and the harmonic frequency with the tuning standard, and giving a tuning suggestion according to a calculation result; and the result output unit is used for outputting a tuning detection result and tuning suggestions. According to the invention, the tuning standard meeting the piano intonation curve is adopted for tuning, so that thetuned tone is intonated, the tone color is natural and harmonious, and the transverse S-shaped intonation curve with higher high pitch and lower low pitch of the piano is met. The problem is solved that different intonation curves cannot be adapted according to different characteristics of each piano, and the intonation curves cannot be automatically corrected according to each piano to be tuned.

Description

technical field [0001] The invention relates to a tuning system, in particular to a piano self-tuning system. Background technique [0002] In order to maintain the accuracy of the piano sound, the piano needs to be regularly checked by professionals to adjust the inaccurate sound. Usually, the home piano needs to be tuned once every six months to one year. For a long time, piano tuning has relied on professional tuners, which is not only expensive and inconvenient, but also the quality of tuning is affected by the level of the pianist. After all, there are very few excellent piano tuners with excellent hearing and high musical literacy. [0003] The present existing piano automatic tuning instrument is expensive and complicated in device, and has poor practicability. Such as the piano automatic tuning device and its automatic tuning method mentioned in patent CN101807391A, this kind of piano automatic tuning device includes a piano body and an automatic tuning device, the ...

AI Technical Summary

Problems solved by technology

However, the existing piano tuner provides adjustment suggestions based on the standard frequency of the piano as a tuning standard. Although each tone of the piano tone that is tuned out as a standard conforms to the standard frequency, the timbre is blunt and lacks the beauty of natural harmony.

Therefore, it is unreasonable to tune according to the standard frequency
