Abstract
Description
Technical Field
[0001] This utility model belongs to the field of wind instrument structure technology, specifically relating to an improved saxophone neck joint. Background Technology
[0002] Traditional saxophone neck connectors have a straight wall or a sharply turned stepped structure inside the joint that connects to the mouthpiece. This structure creates turbulence when the airflow enters the connector cavity, causing airflow dispersion, increased resistance, and weakened feedback. This reduces the player's control over intonation, tone, and breath, affecting the overall playing experience.
[0003] In addition, most existing saxophone neck structures use a single bent tube structure. During long-term use, due to factors such as disassembly, uneven support, or vibration during transportation, local deformation and loosening of the joints are likely to occur, which may even affect pitch and air tightness. This is especially noticeable in high-end performance requirements and precision acoustic testing.
[0004] In view of this, we propose an improved saxophone elbow joint structure. Utility Model Content
[0005] To address the problems existing in the prior art, this utility model provides an improved saxophone elbow joint, which aims to optimize airflow guidance and improve structural durability and airtightness stability.
[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: An improved saxophone neck connector includes: a body, the body having a built-in cavity for gas flow, one end of the body having an interface for connecting with the mouthpiece, and the other end having a plug for connecting with the main body, the outer side of the curved section of the body having an overtone connecting rod, and the inner side having a reinforcing patch, the front end of the interface having an inwardly oblique transition section, and the cross-sectional size of the airflow cavity located at the transition section gradually decreasing from the outside to the inside, forming a conical or arc-shaped gas flow buffer zone.
[0007] Furthermore, a supporting crossbeam is added to the inner side of the curved section of the main body.
[0008] Furthermore, the orthographic projection of the supporting beam falls onto the reinforcing patch.
[0009] Furthermore, the two ends of the supporting beam are welded to the reinforcing patch.
[0010] Furthermore, the transition section has an arc-shaped transition structure at the inward connection point.
[0011] Furthermore, the taper of the airflow cavity at the transition section is 5-40°.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: A transition section is set on the inner side of the interface connecting to the mouthpiece, forming a conical or arc-shaped gas flow buffer zone, which effectively guides the airflow to transition smoothly and reduces turbulence and air resistance; the transition section has an arc transition structure at the inward connection, realizing a smooth transition connection between cavities and constructing an overall smooth gas flow channel, thereby further increasing the smoothness of gas flow; a supporting crossbeam is added to the inner side of the curved section in the main body, and the addition of a rigid crossbeam structure at the bend significantly improves the stability and durability of the joint; while maintaining the compatibility of the original joint, the overall performance is improved; the airflow feedback and pitch control capabilities are optimized, making it especially suitable for frequent disassembly and assembly and high-intensity performance environments.

[0017] To facilitate understanding of this utility model, it will be described in more detail below with reference to the accompanying drawings and specific embodiments. However, this utility model can be implemented in many different forms and is not limited to the embodiments described in this specification. Rather, these embodiments are provided to provide a more thorough and complete understanding of the disclosure of this utility model.
[0018] Example 1: Combination Figure 1-2 Understanding a modified saxophone neck connector, comprising: a body 1, the body 1 having a built-in cavity for gas flow, one end of the body 1 having an interface 2 for connecting to the mouthpiece, and the other end having a socket 3 for connecting to the main body, the body 1 having an overtone connecting rod 4 on the outer side of the curved section and a reinforcing patch 5 on the inner side, the interface 2 having a cork sleeve 7 for enhancing airtightness on the outer side, and a boss 9 at the socket 3; the front end of the interface 2 has an inwardly obliquely cut transition section 8, the cross-sectional size of the airflow cavity located at the transition section 8 gradually decreases from the outside to the inside, forming a conical or arc-shaped gas flow buffer zone, used to guide the blowing gas smoothly to the inside of the neck cavity, avoiding common airflow rebound and turbulence phenomena.
[0019] Combination Figure 3To understand the turbulence problem, the traditional connector 01 has no special design. It is inserted and connected to the mouthpiece 02. It has a stepped structure with straight walls or sharp turns, which causes turbulence problems.
[0020] To enhance gas flow, the transition section 8 features an arc-shaped transition structure at its inward connection and is finely polished to reduce airflow turbulence. This smooth transition between cavities creates a smooth overall gas flow channel, further increasing gas flow.
[0021] In one embodiment, the taper of the airflow cavities at the eight transition sections is 5-40°. This achieves a smooth transition; calculations show that the inner diameter of the airflow cavities shrinks by 30-50%, significantly reducing resistance and ensuring smooth airflow.
[0022] Example 2: Based on the structure of Example 1, a support beam 6 is added to the inner side of the curved section of the main body 1. The two ends of the support beam 6 are fixedly connected to the curved outer shell to form a stable support structure to resist local displacement and bending deformation caused by the insertion force of the flute head, the handling stress or long-term use.
[0023] In one embodiment, a reinforcing patch 5 is provided on the inner side of the body 1. The reinforcing patch 5 is fixed to the bent section of the saxophone elbow joint by laser welding, and the bending profile of the reinforcing patch 5 is consistent with the shape of the elbow at its location. The reinforcing patch 5 can provide a certain degree of enhanced bending resistance. The supporting beam 6 is a brass or nickel-silver alloy die-cast part, fixed by laser welding or precision riveting. It is located below the reinforcing patch 5 at the bent section, and the orthographic projection of the supporting beam 6 falls on the reinforcing patch 5, providing a higher degree of deformation resistance and feedback effect. Alternatively, the supporting beam 6 can be welded to the reinforcing patch 5 to form a closed arc support structure.
[0024] This structure improves playing feedback, stability, and structural strength without changing the compatibility of the interface 2, and is suitable for various models of saxophones, including alto and tenor.
[0025] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.
