Abstract
Description
Technical Field
[0001] This utility model relates to the field of saxophone technology, and in particular to an overtone key for a saxophone. Background Technology
[0002] The saxophone is a reed instrument. The player blows air, causing the reed to vibrate, which in turn causes the air column inside the tube to vibrate, producing sound. Pitch, timbre, and volume are changed by controlling breath, fingering, and embouchure. The harmonic keys are special keys on the saxophone used to trigger extremely high notes. Their core function is to change the vibration pattern of the air column inside the tube, allowing the player to play notes higher than the normal range, typically an octave or higher than the original note.
[0003] Existing harmonic keys are usually truncated cone-shaped with smooth surfaces, which makes them prone to loosening when connected to the tube body.
[0004] Therefore, a saxophone overtone key is proposed to solve the above problem. Utility Model Content
[0005] Given that the existing overtone keys are usually truncated cone-shaped and have smooth surfaces, which makes them prone to loosening when connected to the tube body, this utility model is proposed.
[0006] To solve the above-mentioned technical problems, this utility model provides the following technical solution: a saxophone overtone key, which includes a tube body, an inner cavity formed inside the tube body, and an outer contour of the tube body including an arc-shaped main body, a conical upper part and a lower part, a first mating member provided on the outer side of the upper part, a second mating member provided on the outer side of the lower part, and a resonant tube provided inside the tube body, the resonant tube and the tube body forming a resonant cavity.
[0007] Preferably, the arc-shaped main body comprises two arcs with different curvatures, which smoothly transition at the connection point. The upper diameter of the lower arc is larger than the lower diameter, and the upper diameter of the upper arc is smaller than the lower diameter.
[0008] Preferably, a step is formed at the connection between the upper part and the main body, and a step is formed at the connection between the lower part and the main body.
[0009] Preferably, both the upper and lower connecting parts are provided with raised retaining rings.
[0010] Preferably, the first mating component includes a first lower connecting ring, a first middle connecting ring, and a first upper connecting ring. The first upper connecting ring is disposed on the step formed by the upper connecting portion and the main body portion. The first middle connecting ring is a concave ring that mates with a retaining ring. The second mating component includes a second lower connecting ring, a second middle connecting ring, and a second upper connecting ring. The second upper connecting ring is disposed on the step formed by the lower connecting portion and the main body portion. The second middle connecting ring is a concave ring that mates with a retaining ring.
[0011] Preferably, the first mating part and the second mating part are made of copper.
[0012] The beneficial effects of this utility model are:
[0013] The stability of the tube is improved by setting the main body with rounded ends; the stability of the tube body when connected to the tube body is enhanced by setting retaining rings on the upper and lower joints; and the tightness of the tube body when connected to the saxophone is enhanced by setting the first and second mating parts on the outer sides of the upper and lower joints.

[0019] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.
[0020] Reference Figures 1 to 2As an embodiment of the present invention, a saxophone overtone key is provided. The saxophone overtone key includes a tube body 1, an inner cavity 6 formed inside the tube body 1, and an outer contour of the tube body 1 including an arc-shaped main body, a conical upper part and a lower part. A first mating member 2 is provided on the outer side of the upper part, and a second mating member 3 is provided on the outer side of the lower part. A resonant tube 4 is provided inside the tube body 1, and the resonant tube 4 and the tube body 1 form a resonant cavity 5.
[0021] Specifically, the main body of tube 1 comprises two arc segments with different curvatures at both ends. The diameter of the lower arc segment is larger at the top than at the bottom, and increases from bottom to top. Conversely, the diameter of the upper arc segment is smaller at the top than at the bottom, and decreases from bottom to top. The two arc segments smoothly transition at the connection point. The upper connecting part of tube 1 is generally shaped like a frustum, wider at the bottom than the top. The inner wall of the upper connecting part smoothly transitions with the main body. A raised retaining ring is provided on the upper connecting part to enhance the stability when tube 1 is connected to the tube body. Similarly, the lower connecting part of tube 1 is generally shaped like a frustum, wider at the top than the bottom. The inner wall of the lower connecting part smoothly transitions with the main body. A raised retaining ring is provided on the lower connecting part to enhance the stability when tube 1 is connected to the saxophone head. It is worth noting that tube 1 is a one-piece molded part; the division into the main body, upper connecting part, and lower connecting part is merely for the purpose of describing the structure and positional relationships.
[0022] Specifically, a step is formed at the connection between the upper part and the main body. A first mating part 2 is provided on the outer side of the upper part of the pipe body 1. The bottom of the first mating part 2 is closely attached to the top of the step. The first mating part 2 includes a first lower connecting ring 21, a first middle connecting ring 22, and a first upper connecting ring 23. The first upper connecting ring 23 is closely attached to the step formed by the upper part and the main body. The first mating part 2 is closely attached to the inner wall of the upper part of the pipe body 1. The outer wall of the first mating part 2 is close to the main body of the pipe body 1 without obvious gaps. The first middle connecting ring 22 is a concave ring that mates with the retaining ring. The first mating part 2 enhances the stability of the connection between the pipe body 1 and the pipe body. A step is formed at the connection between the lower part and the main body. A second fitting part 3 is provided on the outer side of the lower part of the tube body 1. The top of the second fitting part 3 is closely attached to the bottom of the step. The second fitting part 3 includes a second lower connecting ring 33, a second middle connecting ring 32, and a second upper connecting ring 31. The second upper connecting ring 31 is closely attached to the step formed by the lower part and the main body. The second fitting part 3 is closely attached to the inner wall of the lower part of the tube body 1. The outer wall of the second fitting part 3 is set without obvious gaps with the main body of the tube body 1. The second middle connecting ring 32 is a concave ring that cooperates with the retaining ring. The second fitting part 3 enhances the stability when the tube body 1 is connected to the saxophone tube head.
[0023] Specifically, pipe body 1 is made of wood, while the first mating part 2 and the second mating part 3 are made of copper.
[0024] Specifically, the tube body 1 has an inner cavity 6, and a resonant tube 4 is installed inside the inner cavity 6. The resonant tube 4 is installed close to the inner wall of the tube body 1, and a resonant cavity 5 is formed between the resonant tube 4 and the tube body 1. The resonant tube 4 is a "C" shaped tube, and the upper and lower ends of the resonant tube 4 are of different lengths. The resonant tube 4 forms a cylindrical sound channel in the inner cavity 6.
[0025] During use, connect the upper part of tube 1 to the tube body, and connect the lower part of tube 1 to the saxophone head.
[0026] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
