Piano adjustment measuring tool and measurement adjusting method thereof

Abstract

The invention provides a piano adjustment measuring tool and a measurement adjustment method thereof. The piano adjustment measuring tool comprises a first measuring tool, a second measuring tool and a third measuring tool. The three measuring tools can be used independently or used in a combined mode to be used for adjustment and comparison, and a basis is provided for tuning and adjustment of all parameters in the piano mechanical tuning process. Tests show that the measuring tool covers all parameters of all mechanical keyboard adjustment, such as the piano striking distance, the keyboard height, the sinking depth, the disconnection distance, the hammer return stroke, the hammer fall-back, and the starting time of a sound arrester, so that piano tuning speed and efficiency are greatly improved. In the aspect of accuracy, through the combined use of several measuring tools, the accuracy of each adjustment parameter is higher, and the error is smaller. Due to the design of the measuring tool, a piano tuner can finish piano tuning and adjusting work more scientifically, more accurately, more efficiently and more comprehensively, and the measuring tool is the first in domestic piano tuning tools.

Description

technical field [0001] The invention relates to the technical field of piano adjustment, in particular to a piano adjustment measuring tool and a measuring and adjusting method thereof; in particular, to a piano adjusting measuring tool and a measuring and adjusting method applicable to blind tuners. Background technique [0002] At present, there are more than 8,000 parts in the piano, most of which are wooden structures. Changes in temperature and humidity will cause wood deformation. To ensure the best pitch and touch of the piano, the piano will be adjusted twice a year for tuning and mechanical touch. The current piano adjustment mainly depends on the experience of the piano tuner. The adjustment results are often different due to the level and subjectivity of the tuner, and the precision and accuracy cannot be guaranteed. Contents of the invention [0003] The object of the present invention is to provide a piano adjustment gauge and its measurement and adjustment me...
