The method comprises the following steps: determining the integrity of the piano seat, the supporting frame, the piano key fixing member and the piano key body; determining the length of the key body; determining the arrangement mode of the key bodies; determining the position of the sound stopping point on the key fixing member by combining different tones and tone sequences; install the key body on key fixed component. Predetermine the length and the range of key body earlier, establish the sound stopping point again, the length and the range of key body can be adjusted wantonly to this kind of method, increase the novelty and the variety of key body.)

1. A method for presetting a sound point of a thumb piano is characterized by comprising the following steps:

s1, determining the integrity of the piano seat, the supporting frame, the piano key fixing member and the piano key body;

s2, determining the length of the key body;

s3, determining the arrangement mode of the key bodies;

s4, combining different tones and tone sequences to determine the position of the sound stopping point on the key fixing member;

s5, mounting the key body on the key fixing member.

2. The method of claim 1, wherein the corners of the key body are rounded.

3. The method for presetting a sound point of a thumb piano as claimed in claim 1, wherein the supporting frame is a stable bracket with at least two layers.

Technical Field

The invention relates to the technical field of musical instruments, in particular to a method for presetting a sound point of a thumb piano.

Background

Most of existing thumb pianos comprise a piano base, a supporting frame, a key fixing component and keys. The thumb piano can produce various tones, and different tones are produced from the positions of the key sound stopping points, and the sound stopping points are at the fixed positions of the keys and the key fixing members. The sound deadening points are located at different positions where the keys are fixed to the key fixing members, and in combination with the length of the keys, different tones of sound are produced.

In the assembly of the thumb piano circulating in the market, the length of a key is fixed after a sound stopping point is fixed, the sound stopping point is fixed on the same horizontal straight line, and then the length of the key is determined according to various tones. The method limits the diversity of keys of the thumb piano and is not beneficial to the development of the thumb piano.

Disclosure of Invention

Technical problem to be solved

Aiming at the defects of the prior art, the invention provides a method for presetting a sound point of a thumb piano, which has the advantages of randomly adjusting the length and the arrangement of keys, increasing the novelty and the diversity of the keys and the like, and solves the problem of single key of the thumb piano.

(II) technical scheme

In order to achieve the purposes of randomly adjusting the length and the arrangement of keys and increasing the novelty and the diversity of the keys, the invention provides the following technical scheme: a method for presetting a sound point of a thumb piano comprises the following steps:

s1, determining the integrity of the piano seat, the supporting frame, the piano key fixing member and the piano key body;

s2, determining the length of the key body;

s3, determining the arrangement mode of the key bodies;

s4, combining different tones and tone sequences to determine the position of the sound stopping point on the key fixing member;

s5, mounting the key body on the key fixing member.

As a preferable technical solution of the present invention, corners of the key body are subjected to smoothing treatment.

As a preferable technical scheme of the invention, the support frame is a stable support with at least two layers.

(III) advantageous effects

Compared with the prior art, the invention provides a method for presetting a sound point of a thumb piano, which has the following beneficial effects: predetermine the length and the range of key body earlier, establish the sound stopping point again, the length and the range of key body can be adjusted wantonly to this kind of method, increase the novelty and the variety of key body.
