Description

Technical Field

[0001] This utility model relates to the field of saxophone technology, and in particular to a high-density key structure and a saxophone. Background Technology

[0002] As a widely used musical instrument, the sound quality and performance of the saxophone depend heavily on the tightness of the fit between its various components.

[0003] Traditional saxophone body connections typically use flat butt joints or simple socket joints, which are prone to deformation under temperature, humidity changes, or mechanical stress, leading to seal failure at the joints and consequently affecting tone. Sealing failure causes airflow leakage, altering the stability of the air column vibration within the saxophone body, thus affecting intonation and tone. To improve the structural stability and sealing performance of the joints and avoid tone changes caused by deformation, we propose a high-density key structure and saxophone design to address these issues. Utility Model Content

[0004] This invention provides a high-density key structure and saxophone, solving the technical problem of poor key sealing performance in current saxophones.

[0005] To solve the above-mentioned technical problems, this utility model provides a high-density key structure and saxophone, including a mouthpiece, a neck tube, and a body. The mouthpiece is fixedly connected to the neck tube, and the neck tube is sealed to the body. The body has a plurality of tone holes of different sizes distributed on it, and a tone cap is provided on the tone holes. A sealing element is provided between the tone holes and the tone cap. When the tone cap is closed with the tone holes, the tone holes are at least partially embedded in the tone cap. A tuning linkage shaft is fixedly connected to the tone cap, and the tuning linkage shaft is fixed to the body.

[0006] Preferably, the various sound hole posts of different sizes protrude from the outer surface of the tube.

[0007] The above technical solution involves several sound holes of varying sizes protruding from the outer surface of the tube, facilitating their fit with the sound cover.

[0008] Preferably, the sound cover has a groove on the side near the sound hole post.

[0009] The above technical solution is adopted: a groove is opened on the side of the tone cap near the tone hole post, so that the tone cap can cover the tone hole post when the saxophone is played.

[0010] Preferably, the size of the groove is adapted to the size of the sound hole post.

[0011] The above technical solution is adopted: by matching the size of the groove with the size of the sound hole post, the sound cover can be tightly covered on the sound hole post.

[0012] Preferably, the seal includes a sealing gasket.

[0013] The above technical solution is adopted to increase the sealing performance between the cover and the sound hole column when they are closed by using a sealing component, including a sealing gasket.

[0014] Preferably, the sealing gasket is embedded in the sound hole post, and the sealing gasket at least partially protrudes from the sound hole post.

[0015] The above technical solution involves embedding a sealing gasket inside the sound hole post, with the gasket at least partially protruding from the sound hole post, thereby further enhancing the sealing performance between the sound cover and the sound hole post when they are closed.

[0016] Preferably, the sound hole post has an annular groove, the size of which is adapted to the size of the sealing gasket.

[0017] The above technical solution involves creating an annular groove on the sound hole column, the size of which is adapted to the size of the sealing gasket, facilitating the installation of the sealing gasket inside the sound hole column.

[0018] Preferably, the depth of the annular groove is less than the height of the sealing gasket.

[0019] The above technical solution is adopted: by making the depth of the annular groove less than the height of the sealing gasket, the sealing gasket can protrude from the sound hole post when it is installed on the sound hole post.

[0020] Preferably, the annular groove has a toothed groove on its annular wall and a toothed protrusion is provided along the circumference of the outer ring of the sealing gasket. The size of the toothed protrusion is adapted to the size of the sealing gasket. The toothed groove is provided in at least one circle along the annular wall of the annular groove, and the toothed protrusion is provided in at least one circle along the circumference of the outer ring of the sealing gasket.

When the sound cover and soundhole post are closed, the soundhole post is at least partially embedded within the sound cover. A tuning linkage shaft is fixedly connected to the sound cover and is fixed to the body of the saxophone. This design creates a segmented connection between the sound cover and the soundhole post, offering several advantages: The complementary nature of the geometric shapes enhances the stability and sealing of the connection; the concave-convex structure disperses external stress, reducing the impact of local deformation on the overall structure; the concave-convex connection between each sound cover and soundhole post forms a modular structure; and the addition of a seal between the sound cover and the soundhole post further enhances the saxophone's sealing performance during performance, preventing changes in tone during playing.
