Embodiment Construction

[0022] The implementation of the tuning mode selection mechanism of the present invention will be described in detail below.

[0023] When an upright piano is played, do not hit the keys violently with your hands or step on the pedals with your feet, so as not to cause mechanical damage to the strings and breakage of the pedal springs, and do not use sharp instruments to depict the keys and the surface of the paint film. When opening and closing the piano cover, do not move too violently. The bookshelf should be closed first, so as not to damage the keys when opening and closing the piano cover. After the piano is used, all the lids should be closed, and the piano cover should be covered to prevent the intrusion of dust.

[0024] In order to overcome the above disadvantages, the present invention builds a tuning mode selection mechanism, which can effectively solve the corresponding technical problems.

[0025] The tuning mode selection mechanism shown according to the embodi...

Abstract

The invention relates to a tuning mode selection mechanism, comprising an upright piano body and an automatic tuning device, wherein the upright piano body comprises a spring rail, a spring rail felt,a mallet handle, mallet rail felt cloth, a silencer bar, a silencer spring, a winch steel pin, a rear cage, a humidity sensor and a red indicator light, the humidity sensor is used for sensing the humidity of a current location of the upright piano body to output the humidity as current humidity; the red indicator light is connected with the humidity sensor, and is used for displaying with red light at a preset frequency when the current humidity is greater than or equal to a preset humidity threshold value; the red indicator light is also used for stopping displaying with the red light at the preset frequency when the current humidity is less than the preset humidity threshold value; the automatic tuning device is used for determining a corresponding tuning mode based on a received current user number, and performing corresponding tuning processing on the upright piano body based on the determined tuning mode. By means of the tuning mode selection mechanism, the tuning flexibility ofan upright piano is improved.

Description

technical field [0001] The invention relates to the field of upright pianos, in particular to a tuning mode selection mechanism. Background technique [0002] Upright piano tuning pegs are nail-shaped bolts that can be twisted and rotated with a special wrench. Its turning bed is made of special high-carbon steel with locks, so the strings can be firmly wound on the pegs, so that the intonation can be maintained and stabilized for a long time under the high-strength tension of the strings. The hammer is covered with high-quality felt or flannelette. Because this layer of "skin" is mostly made of wool, it is also called wool mallet. It itself is attached to the key, and when the key is pressed, the hammer will hit the strings and make the piano sound by the vibration of the strings. Therefore, his function is to strike the strings tightly fastened by the tuning nails. [0003] The damper is close to the string and is used to stop the vibration of the string. For example, ...
