Hammer head group and preparation method thereof

Abstract

The invention relates to the field of piano part production, and particularly discloses a hammer head group and a preparation method thereof. The hammer head group comprises a high-pitch area hammer head, an alto-pitch area hammer head and a low-pitch area hammer head which are arranged in sequence, the height of the bass area hammer head is 64 to 64.8 mm; the height of the hammer head in the alto range from 72 m to 72.8 m and the height of the hammer head in the treble range from 72 m to 72.8 m; the preparation method comprises the following steps: S1, preparing the hammer last splicing strip, and preparing the outer-layer felt and the inner-layer felt; s2, inner-layer felt and outer-layer felt are sequentially compounded on the surfaces of the hammer last splicing strips in a hot-pressing mode; s3, polishing the surface of an outer felt layer of the pre-composite body B, and slitting to obtain 88 hammer head pre-treated pieces A; s4, the hammer head pretreatment piece A is subjected to laser coding and then lustring treatment, and a hammer head pretreatment piece B is obtained; and S5, after the hammer head pretreatment piece B is subjected to drilling treatment, the hammer head component is prepared and obtained. The product provided by the invention has the advantage of improving the sound quality after the hammer heads in different sound areas hit the strings.

Description

technical field [0001] The application relates to the field of production of piano parts, in particular to a hammer set and a preparation method thereof. Background technique [0002] The hammer is an important part of the piano action. Since the piano is an instrument composed of 88 keys and a metal string soundboard, the piano produces sound through the hammer bridge and the soundboard to generate vibration after the hammer strikes the strings. Yes, 88 keys correspond to 88 hammers, that is, 88 hammers are used as a hammer group. Different hammers will produce different sounds after hitting the strings, so the quality of the hammers is very important to the piano tone. [0003] The 88 keys of the piano can be divided into high-pitched, mid-range and low-pitched ranges according to the sound range. Different sound ranges will produce different sounds, so the hammers corresponding to the keys can also be divided into high-pitched range hammers, mid-range Zone Hammers and Ba...

[0005] However, although the thickness of the second connecting block of the mallet bar gradually becomes smaller along the direction away from the first connecting block, although the sound of the hammer hitting the string in different registers will be different, the sound of the hammer hitting the string is still not enough. vigorous
