String fine tuning device

Abstract

The embodiment of the invention provides a string fine tuning device which comprises a switch module, a storage module, a signal receiving module and at least one driving module which are all connected with a processing module, a first-stage gear is connected with the corresponding driving module, and a last-stage gear is meshed with the lower end of a tuning knob of one string. The processing module obtains a first frequency value according to the first sound signal of the to-be-tuned string received by the signal receiving module, judges a frequency standard value closest to the first frequency value according to the first frequency value and the frequency standard values of all strings stored by the storage module, generates a fine tuning control signal according to a first difference value between the first frequency value and the closest frequency standard value, and sends the fine tuning control signal to the driving module corresponding to the string to be tuned. The driving module drives the first-stage gear corresponding to the string to be tuned according to the fine tuning control signal, and the last-stage gear adjusts the tuning knob corresponding to the string to be tuned under the driving of the first-stage gear, so that the tuning of the string to be tuned is realized.

Description

technical field [0001] The embodiments of the present application relate to the field of musical instrument tuning, and in particular, to a string fine-tuning device. Background technique [0002] The stringed qin is an excellent plucked musical instrument in my country, with a long history and distinctive features, and is deeply loved by the masses of the people. However, the strings are easily affected by climate change and changes in dryness and humidity, resulting in poor intonation. Therefore, before using stringed instruments, they must be tuned to achieve the best possible intonation. [0003] In the prior art, the strings are generally tuned according to experience, or various chord application programs are downloaded, and the strings are manually adjusted according to the prompts of the application programs to achieve the best pitch. [0004] However, the above tuning method is used for tuning, the tuning is not accurate enough, the tuner needs to be carried separ...

Problems solved by technology

[0004] However, if the above-mentioned tuning method is used for tuning, the tuning is not accurate enough, and the tuner needs to be carried separately, and the strings are easy to break during manual tuning, and it is also easy to suddenly loosen the strings, and often needs to be re-tuned
