Technical Field

[0001] The utility model relates to the technical field of piano manufacturing and maintenance, in particular to a measurement auxiliary tool for a piano bridge. Background Art

[0002] The sound of the piano is produced by stimulating the vibration of the strings and the resonance of the soundboard. Structurally, there must be a mechanical connection between the strings and the soundboard in order to transfer the vibration energy of the strings to the soundboard. Therefore, bridges are designed in all string instruments. The strings transfer the vibration energy to the soundboard through the bridges. Therefore, the pressure exerted by the strings on the bridges has become one of the key factors affecting the resonance quality of the piano sound.

[0003] When manufacturing and repairing the bridge of a piano, it is necessary to accurately measure and correct it in order to achieve an accurate string pressure ratio and improve the quality of piano sound resonance.
