Problems solved by technology

Due to the thickness of the tube wall, its sensitivity is also low, resulting in a more "real" sound, and the effort and physical energy consumption of the performance is correspondingly greater.
In order to solve the timbre problem of the range, the existing number nozzles are usually designed with a certain type of nozzle focusing on the treble, a certain type of nozzle focusing on the bass or a certain type of nozzle in the middle range. It is easy to play in a narrow range, and the timbre will be more consistent

Embodiment Construction

[0015] The present invention is described in further detail by the following examples.

[0016] see figure 2 As shown, a double-layer conduit number nozzle of a brass instrument is composed of a cup-shaped nozzle 11, an inner thin-walled conical conduit 13 and an outer protective tube 12. The cup-shaped nozzle 11 is provided with an inner hall 14, and the inner layer is thin-walled. The lumen of the conical catheter 13 is connected with the inner hall 14 . The rear end of the cup-shaped mouth 11 and the front end of the inner layer thin conduit 13 are threaded, or can be tightly fitted or welded, or even integrated. Both the front end and the rear end of the inner layer conduit 13 are provided with a small section of cylindrical surface, which is the fastening fitting part for the combination of the inner layer conduit 13 and the outer protective tube 12 . The two fitting connection methods can adopt methods such as tight fit or screw fastening or welding. The function of ...

Description

technical field [0001] The invention relates to the technical field of brass instruments, in particular to a double-layer conduit number nozzle for brass instruments. Background technique [0002] Brass instruments are Zuizi instruments, and Zuizi are often called Haozui. The number nozzle plays a key role in the performance of the performance, the quality of the tone and sound quality. [0003] The number that existing brass instruments are used is to be chewed by one section cup-shaped chewing 1 and one section conical conduit 2 to form, see figure 1 As shown, most of them are integrated, and a small part is detachable and separable. But the conduit sections of all these nozzles are all single-layer pipe wall, and pipe wall is thicker, approximately in the scope of 1-2mm. When the sound and air played by the performer pass through the duct, there is less vibration due to the thickness of the duct wall. Also, due to the thickness of the conduit wall, its sensitivity is ...
