Embodiment Construction

[0033] In order to enable those skilled in the art to better understand the technical solutions of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0034] In one embodiment, such as figure 1 Shown, a kind of piano automatic tuning method, the method comprises the following steps:

[0035] Step S200: Obtain the current frequency of the sound emitted when the current key is pressed. When the current frequency of the sound is inconsistent with the preset standard frequency of the current key, obtain the current position of the tuning wrench and the position of the peg pin corresponding to the current key. The current position of the tuning wrench and the position of the peg pin corresponding to the current key control the stepping motor to move the tuning wrench from the current position to the position corresponding to the peg pin of the current key;

[0036] Step S300: Automatically insert t...

Abstract

The invention discloses an automatic piano tuning method, which comprises the following steps of: acquiring a current sound frequency generated when a current key is pressed, and when the current sound frequency is inconsistent with a preset standard frequency of the current key, according to the current position of a tuning wrench and the position of a tuning peg pin corresponding to the current key, controlling a stepping motor to move the tuning wrench from the current position to the position of the tuning peg pin corresponding to the current key; automatically sleeving the tuning wrench into the tuning peg pin corresponding to the current key through a rotation probing method according to a preset rotation principle; subtracting a preset standard frequency of the current key from the current sound frequency to obtain a frequency difference value, and controlling the stepping motor to drive the tuning wrench to rotate according to the obtained rotation information according to the frequency difference value and a preset frequency difference value-rotation information corresponding relation until the current sound frequency is consistent with the preset standard frequency of the current key; and according to a preset safe exit principle, controlling the stepping motor to drive the tuning wrench to exit safely until tuning of all the keys is completed.

Description

technical field [0001] The invention belongs to the field of musical instrument tuning, in particular to an automatic tuning method for a piano. Background technique [0002] With the development and progress of the society, more and more people are using the piano now, and after a period of playing the piano and the influence of temperature and humidity changes, it will directly affect the intonation and the auditory experience of the audience. Only by tuning can the pitch be guaranteed. [0003] The existing method is to invite a professional piano tuning lawyer to come to tune the tune, which is not only limited by the listening level of the tuner itself, but also needs to increase the cost of tuning. Therefore, there is an urgent need for a method that can realize automatic piano tuning , to solve the existing tuning problems. Contents of the invention [0004] In view of the above technical problems, the present invention provides a method for automatic piano tuning...
