Piano action sensitivity tester and working method thereof

Abstract

The invention relates to a piano action sensitivity tester comprising a rack; a keystroke device is arranged on the rack, a contact is arranged on the keystroke device, and the keystroke device is suitable for driving the contact to reciprocate up and down so as to drive the contact to hit piano keys in a reciprocating manner. The working method of the piano action sensitivity tester comprises the following steps: step S01, the tester moves, and the contact of the keystroke device moves to a position above the piano keys; S02, a linear module drives the keystroke device to move downwards until the contact is close to the piano keys; and S03, a driving piece drives the contact to move up and down in a reciprocating manner, so that the contact knocks the piano keys in a reciprocating manner. The piano keys can be knocked repeatedly, so that when a worker detects the sensitivity of the piano keys, the worker does not need to knock the piano keys by himself, the detection intensity of the worker is reduced, and the worker can concentrate on sensing whether the sound of the piano keys is uniform or not through auditory sense.

Description

technical field [0001] The invention relates to a piano action sensitivity tester and a working method thereof. Background technique [0002] The piano is a representative of keyboard instruments, and has the reputation of the king of musical instruments. With the improvement of people's living standards in our country, parents pay more attention to the aesthetic education of their children. At present, my country is the largest producer and consumer of pianos in the world. The prosperous market brings opportunities not only to regular manufacturers, but also to speculators. There are the following points to evaluate the quality of piano: 1. Timbre; 2. Feel; 3. Stability. The tone needs to be discerned by the ear, and there is also a personal preference, and the stability needs time to verify. What we usually call feel should actually be defined as the sensitivity of the piano action, which is called the number of seconds of the same key hit in the industry, that is, the ...

Problems solved by technology

[0005] The technical problem to be solved by the present invention is: to overcome the deficiencies in the prior art, to provide a piano action sensitivity tester and its working method, to solve the current problem of detecting the sensitivity of the piano keys, because the knocking of the keys mainly depends on the working method. It is realized by personnel, which leads to the problem of low efficiency of key sensitivity detection
