Vertical key piston of brass instrument

Abstract

The invention provides a vertical key piston of a brass instrument. The problems that in the prior art, the processing steps of a piston are complex and multiple, the steps are all completed through manual operation, so that time and labor are wasted, the production efficiency is low, the product pass percent is low, the quality is poor, and sound production of the instrument is directly influenced due to unsmooth airstreams caused by the structure of the current piston are solved. The vertical key piston of the brass instrument comprises a piston body and a piston handle, wherein an air drain is formed in the piston body and the piston body and the piston handle are integrally formed. According to the vertical key piston of the brass instrument, a traditional air hole is replaced by the air drain, the air drain can be directly formed in the piston body, the production steps are greatly simplified, production in batches can be achieved through a machine, the labor cost and the material resource cost of manual manufacture are greatly reduced, the production efficiency is high, the product pass percent is high, and the quality is good. In addition, the traditional air hole is replaced by the air drain, so that the direction of the airstreams is more reasonable, the airstreams are smoother, and the vertical key piston of the brass instrument is an exceptional innovative product.

Description

technical field [0001] The invention relates to the field of musical instruments, in particular to a brass instrument vertical key piston. Background technique [0002] A brass instrument is an instrument in which air is blown into a mouthpiece, causing the lips to vibrate. They were also known as "labrosones", which literally means "lip-vibrating instruments" (Baines). To change the pitch on a keyed instrument, there are two ways to do it: 1. Depress the key to change the length of the tube, and 2. Change the vibration frequency of the lips by the air blown by the player. There are generally two families of modern brass instruments: [0003] 1. Button-type brass instrument: it is a combination of several buttons (usually 3 or 4, but there are also 7 or more), and the player's fingers adjust the length of the pipe according to the needs of the performance. This family includes all modern brass instruments except trombones: [0004] Soprano instruments: trumpet, cornet, s...

AI Technical Summary

Problems solved by technology

[0012] The invention proposes a brass musical instrument vertical key piston, which solves the problems of the prior art that the piston has many processing steps, and the steps are all completed by manual operation, which not only takes time and effort, but also has low production efficiency, and the product qualification rate is low and the quality is poor.
