Problems solved by technology

The pronunciation method of brass instruments is to change the pitch by changing the air pressure of the player's lips and the method of connecting the additional tube of the instrument itself. When practicing playing brass instruments, it is necessary to install a mouthpiece pressure reducer between the mouthpiece and the brass instrument, and adjust the pressure of the lips when playing through the spring in the mouthpiece pressure reducer, and remove it when the pronunciation is accurate The mouthpiece pressure reducer carries out normal playing, and the mouthpiece pressure reducer helps the blowing training of brass instruments; But, the pipe diameter that existing mouthpiece pressure reducer is connected with number mouth and musical i

Abstract

The invention discloses a pressure reducing device for a horn mouth of a brass instrument. The pressure reducing device comprises a pressure reducer body. The left side of the pressure reducer body isconnected with an air inlet pipe. An air inlet cavity is formed in the air inlet pipe. The outer wall of the left side of the air inlet pipe is in threaded connection with a sleeve A. An exhaust pipeis connected to the right side of the pressure reducer body, an exhaust cavity is formed in the exhaust pipe, a sleeve B is connected to the outer wall of the right side of the exhaust pipe in a threaded mode, a pressure reducing cavity is formed in the pressure reducer body, and a pressure reducing mechanism and a limiting mechanism are arranged in the pressure reducing cavity. In general, the device has the advantages of being convenient to use, capable of being connected with horn mouths and musical instruments with different pipe diameters, wide in application range, not prone to slidingduring playing and long in service life, and the horn mouths and the musical instruments cannot be abraded during mounting and dismounting.

Description

technical field [0001] The invention belongs to the technical field of brass instrument auxiliary equipment, in particular to a brass instrument mouthpiece decompression device. Background technique [0002] A brass instrument is an instrument in which air is blown into the mouthpiece, causing the lips to vibrate. The pronunciation method of brass instruments is to change the pitch by changing the air pressure of the player's lips and the method of connecting the additional tube of the instrument itself. When practicing playing brass instruments, it is necessary to install a mouthpiece pressure reducer between the mouthpiece and the brass instrument, and adjust the pressure of the lips when playing through the spring in the mouthpiece pressure reducer, and remove it when the pronunciation is accurate The mouthpiece pressure reducer carries out normal playing, and the mouthpiece pressure reducer helps the blowing training of brass instruments; But, the pipe diameter that exi...
