Description

A saxophone Technical Field

[0001] This invention relates to the field of musical instrument technology, and more particularly to a saxophone. Background Technology

[0002] The saxophone, a wind instrument combining the explosive power of brass instruments with the delicate tone of woodwind instruments, has been widely used in classical, jazz, and popular music genres since its invention in 1840 by Belgian instrument maker Adolphe Sax. Its unique tonal expressiveness has made it an indispensable instrument in modern music performance. Its core structure mainly includes the mouthpiece, mouthpiece, reed, main tube, tone holes, key mechanism, and bell. Its working principle involves the player vibrating the reed with their lips, which in turn vibrates the air column inside the mouthpiece. This vibration, in turn, generates the fundamental tone through the resonance of the air column in the main tube. Simultaneously, pressing different keys controls the opening and closing of the tone holes, changing the effective length of the air column and thus achieving different pitches.

[0003] In existing technologies, the main body, bell, and key mechanism of a saxophone are mostly formed by integrated welding or precision casting, resulting in a relatively fixed structure. This fixed structure means that the assembly of each component must be completed in a specific process. If a single component has a dimensional deviation or is damaged during assembly, the entire structure often needs to be adjusted or replaced. This not only increases assembly time and costs but also raises the scrap rate, thus increasing the overall manufacturing cost. At the same time, the fixed structure also increases the difficulty of saxophone maintenance. When core components such as the key mechanism and tone holes malfunction, maintenance personnel need to disassemble the entire instrument. Some integrated components cannot be replaced individually and must be replaced as a whole, significantly increasing the user's maintenance costs.

[0004] Furthermore, the mouthpiece is the most important component of the saxophone, directly affecting the instrument's sound production and tone. It consists of the body and the reed. The reed is attached to the body via a connecting component. When air is blown, the airflow passes through the reed and vibrates. The vibrating airflow resonates with the air column to produce sound. In current technology, the reed of a typical mouthpiece requires frequent cleaning, replacement, or polishing. However, the connection between the reed and the mouthpiece body is relatively complex, with high processing difficulty and manufacturing costs. Moreover, reed installation is very inconvenient, especially for children and beginners, who may find it difficult to install the reed in the correct position, thus affecting the musical effect and resulting in a poor user experience. In addition, the reed installation process is cumbersome. In short, the manufacturing cost is high, and the instrument is inconvenient to use. Summary of the Invention

[0005] The purpose of this invention is to provide a saxophone that aims to at least solve one of the technical problems existing in the prior art.

[0006] To achieve the above objectives, the present invention provides a saxophone, comprising:

[0007] The tube body is hollow to form a through airflow channel inside. Multiple tone holes are provided on the side wall of the tube body. The tube body has a first open end and a second open end. A mouthpiece is detachably installed at the first open end, and a horn is detachably installed at the second open end.

[0008] A key structure is detachably mounted on the tube body and is movable relative to the tube body between a closed position and an open position, such that in the closed position, the key structure can cover and close at least part of the tone hole, and in the open position, the tone hole communicates with the airflow channel and the external environment.

[0009] Furthermore, the flute head includes a flute body and a reed. A reed bed is provided on one side of the flute body, and a insertion groove is provided on the reed bed so that the reed can be detachably installed on the reed bed by inserting the reed into the insertion groove.

[0010] Furthermore, the sentry bed is provided with a U-shaped limiting structure, and the side of the U-shaped limiting structure away from the sentry bed extends inward to form a blocking edge, thereby forming an insertion groove between the sentry bed, the U-shaped limiting structure, and the blocking edge; or

[0011] The lateral surface of the end of the reed is provided with a insertion flange extending outward from its outer side, so that the end of the reed can be detachably inserted into the insertion groove by inserting the insertion flange from the opening into the insertion groove.

[0012] Furthermore, the tube body includes:

[0013] The inner tube has multiple sound holes disposed on the side wall of the inner tube, and the inner circumferential wall of the sound hole extends outward to form a protruding circumferential wall structure.

[0014] The first outer tube structure has multiple clearance holes, each clearance hole corresponding to a protruding annular wall structure. The first outer tube structure is detachably mounted on the inner tube, and the key structure is detachably mounted on the first outer tube structure.

[0015] Furthermore, the first outer tube structure is provided with a first fastening structure on the side facing the inner tube, and the outer circumferential surface of the inner tube is provided with a second fastening structure, so that when the first outer tube structure is installed on the inner tube, the first fastening structure and the second fastening structure are engaged.

[0016] Furthermore, the first fastening structure includes a plurality of fastening grooves, which are spaced apart along the length of the inner tube, and the second fastening structure includes a plurality of fastening protrusions, which are arranged in a one-to-one correspondence with the fastening grooves.

[0017] Furthermore, the tube body also includes a second outer tube structure, which is installed on the inner tube, and the first outer tube structure is located on one side of the inner tube, while the second outer tube is located on the other side of the inner tube, so as to cover the circumferential surface of the inner tube through the first outer tube structure and the second outer tube structure.

[0018] Furthermore, the second outer tube structure is provided with a third fastening structure on the side facing the inner tube, and the outer circumferential surface of the inner tube is provided with a fourth fastening structure, so that when the second outer tube structure is installed on the inner tube, the third fastening structure and the fourth fastening structure are engaged.

[0019] Furthermore, the pipe body is provided with a mounting platform structure, which includes multiple mounting platform units and a shaft. The multiple mounting platform units are spaced apart along the length direction of the pipe body to form an installation space between two adjacent mounting platform units. The shaft is provided through the mounting platform unit along the length direction of the pipe body to form a shaft connection in the installation space.

[0020] The key structure includes multiple key units, which are rotatably mounted on the shaft connection to close or open the tone hole.

[0021] Furthermore, the key unit includes:

[0022] A torsion spring, which is inserted through the shaft connection portion, and the torsion spring includes a first end and a second end;

[0023] The key body is inserted through the shaft connection part, with the first end abutting against the tube body and the second end abutting against the key body, so that the key body can be driven by the elastic force of the torsion spring to open the tone hole.

[0024] As can be seen from the above technical solution, the saxophone of the present invention, through the detachable connection design of the tube body, mouthpiece, horn and key structure, allows the factory to not strictly follow fixed procedures during the production process. When a single part is dimensionally deviated or damaged, it only needs to be replaced individually without adjusting the overall structure. This greatly reduces the scrap rate and assembly time, simplifies the production process, effectively controls the overall manufacturing cost of the factory, and the detachable structure makes it easy to disassemble, clean, maintain and carry the instrument, further improving the user's convenience.

[0034] To enable those skilled in the art to better understand the technical solutions of this application, the technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0035] Please refer to Figures 1 to 8. This embodiment provides a saxophone, including a tube body and a key structure 500. The tube body is hollow to form a through airflow channel inside. Multiple tone holes 120 are provided on the side wall of the tube body. The tube body has a first open end 140 and a second open end 150. A mouthpiece 200 is detachably installed on the first open end 140, and a horn 300 is detachably installed on the second open end 150. The mouthpiece 200 includes a tube body 210 and a reed 230. A reed bed 211 is provided on one side of the tube body 210. A U-shaped limiting structure 220 is provided on the reed bed 211. The U-shaped limiting structure 220 is located away from the reed bed. One side of the reed bed 211 extends inward to form a blocking edge 221. The reed bed 211 has a insertion groove, specifically formed between the reed bed 211, the U-shaped limiting structure 220, and the blocking edge 221. The reed 230 is detachably mounted on the reed bed 211 by inserting it into the insertion groove. The key structure 500 is detachably mounted on the tube body and is movable relative to the tube body between a closed position and an open position. In the closed position, the key structure 500 covers and closes at least part of the tone hole 120. In the open position, the tone hole 120 connects to the airflow channel and the external environment. The reed bed 211 has an air inlet 212.

[0036] As can be seen, the saxophone in this embodiment, through the detachable connection design of the tube body with the mouthpiece 200, horn 300 and key structure 500, allows the factory to avoid strictly following fixed procedures during production. When a single component has a dimensional deviation or is damaged, it only needs to be replaced individually without adjusting the overall structure, which greatly reduces the scrap rate and assembly time, simplifies the production process, and effectively controls the overall manufacturing cost of the factory. The U-shaped limiting structure 220 and the blocking edge 221 at the reed bed 211 form a plug-in groove type reed 230 installation structure. The reed 230 only needs to be inserted into the plug-in groove to complete the installation, ensuring the consistency of the reed 230 installation position. The operation is simple and convenient, solving the problem that novices have difficulty installing correctly. Moreover, the detachable structure makes it easy for the instrument to be disassembled for cleaning, maintenance and carrying, further improving the user's convenience.

[0037] In this embodiment, please refer to Figures 1 to 7 together. The tube body includes an inner tube 100 and a first outer tube structure 400. Multiple tone holes 120 are disposed on the side wall of the inner tube 100. The inner circumferential wall of the tone hole 120 extends outward to form a protruding annular wall structure 130. Multiple clearance holes 410 are provided on the first outer tube structure 400. The clearance holes 410 are provided one-to-one with the protruding annular wall structures 130. The first outer tube structure 400 is detachably installed on the inner tube 100. The key structure 500 is detachably installed on the first outer tube structure 400.

[0038] In this design, the tube body is detachably combined with the inner tube 100 and the first outer tube structure 400. The inner circumferential wall of the sound hole 120 protrudes outward to form a protruding ring wall structure 130, and the first outer tube structure 400 is correspondingly provided with a clearance hole 410. On the one hand, the inner tube 100 and the first outer tube structure 400 can be manufactured separately, improving the processing accuracy and quality stability of each component. If a component has a dimensional deviation or is damaged, only the corresponding component needs to be replaced, without scrapping the entire tube body, further reducing manufacturing and maintenance costs. On the other hand, the first outer tube structure… Structure 400 provides an independent and stable mounting base for key structure 500. The one-to-one correspondence between the avoidance hole 410 and the protruding ring wall structure 130 can prevent the first outer tube structure 400 from blocking or interfering with the tone hole 120, ensuring that the tone hole 120 can smoothly connect the airflow channel and the external environment when in the open position, ensuring the accuracy of saxophone sound production and tone stability. At the same time, the detachable structure facilitates the disassembly and cleaning of inner tube 100 and first outer tube structure 400, reducing the impact of impurities in the airflow channel on the playing effect, and improving the overall reliability and user experience of the instrument.

[0039] Preferably, as shown in FIG2, the first outer tube structure 400 is provided with a first fastening structure 420 on the side facing the inner tube 100, and the outer peripheral surface of the inner tube 100 is provided with a second fastening structure 160, so that when the first outer tube structure 400 is installed on the inner tube 100, the first fastening structure 420 and the second fastening structure 160 are engaged.

[0040] The design of the first snap-fit ​​structure 420 on the side of the first outer tube structure 400 facing the inner tube 100 engaging with the second snap-fit ​​structure 160 on the outer circumference of the inner tube 100 enables quick and stable assembly of the inner tube 100 and the first outer tube structure 400. During assembly, only the snap-fit ​​structure needs to be aligned to complete the fixation, which is simple and efficient, greatly shortening the assembly time of the tube components. Moreover, the snap-fit ​​structure can form a stable connection and positioning, effectively preventing the first outer tube structure 400 from shifting or loosening relative to the inner tube 100 during use. This ensures that the clearance hole 410 on the first outer tube structure 400 and the protruding ring wall structure 130 of the inner tube 100 always maintain a precise correspondence, preventing problems such as the sound hole 120 being blocked or airflow being obstructed due to component misalignment. It also ensures the opening and closing control accuracy of the key structure 500 on the sound hole 120, thereby maintaining the stability and tonal consistency of the saxophone. While continuing the core advantages of the detachable design, it further improves the connection reliability and assembly accuracy of the tube structure, optimizing the performance and durability of the instrument.

[0041] In this embodiment, the first fastening structure 420 includes a plurality of fastening grooves, which are spaced apart along the length of the inner tube 100. The second fastening structure 160 includes a plurality of fastening protrusions, which are corresponding to the fastening grooves one by one.

[0042] Specifically, the first fastening structure 420 is designed as a plurality of fastening grooves spaced apart along the length of the inner tube 100, and the second fastening structure 160 is provided with a plurality of fastening protrusions. The spaced fastening grooves and fastening protrusions engage one by one, which can form a uniform force fixing effect from multiple points along the length of the inner tube 100, effectively preventing the first outer tube structure 400 from rotating circumferentially or displacing axially relative to the inner tube 100, ensuring that the clearance hole 410 on the first outer tube structure 400 and the protruding annular wall structure 130 of the inner tube 100 always maintain precise alignment, thus optimizing the overall performance and durability of the instrument.

[0043] Preferably, the tube body further includes a second outer tube structure 600, which is mounted on the inner tube 100. The first outer tube structure 400 is located on one side of the inner tube 100, and the second outer tube is located on the other side of the inner tube 100, so that the side peripheral surface of the inner tube 100 is covered by the first outer tube structure 400 and the second outer tube structure 600.

[0044] The second outer tube structure 600 and the first outer tube structure 400 together cover the side surface of the inner tube 100, achieving all-round protection of the tube body. This effectively resists damage to the core inner tube 100 from external collisions and wear, significantly improving the mechanical strength and durability of the tube body structure and extending the service life of the instrument. In addition, the assembly of the second outer tube structure 600 and the inner tube 100 continues the detachable design logic, allowing for individual processing and replacement. It can replace a damaged outer tube without having to scrap the entire tube body.

[0045] In this embodiment, a third fastening structure 610 is provided on the side of the second outer tube structure 600 facing the inner tube 100, and a fourth fastening structure 170 is provided on the outer circumferential surface of the inner tube 100, so that when the second outer tube structure 600 is installed on the inner tube 100, the third fastening structure 610 and the fourth fastening structure 170 are engaged.

[0046] Among them, the third fastening structure 610 is a groove structure, and the fourth fastening structure 170 is a protrusion structure. The protrusion structure can be engaged into the groove structure, realizing a precise, stable and detachable connection between the second outer tube structure 600 and the inner tube 100.

[0047] Preferably, the outer surface of the tube body is provided with a mounting platform structure 430, which includes a plurality of mounting platform units 431 and a shaft 432. The plurality of mounting platform units 431 are spaced apart along the length direction of the tube body to form a mounting space 433 between two adjacent mounting platform units 431. The shaft 432 is provided through the mounting platform unit 431 along the length direction of the tube body to form a shaft connection portion 432a in the mounting space 433. The key structure 500 includes a plurality of key units 510, which are rotatably mounted on the shaft connection portion 432a to close or open the tone hole 120.

[0048] The tube body is provided with a mounting platform structure 430 consisting of multiple spaced mounting platform units 431 and a through shaft 432. A shaft connection part 432a is formed between adjacent mounting platform units 431, and the key unit 510 can be rotatably mounted on the shaft connection part 432a. This provides a precise and stable mounting reference for the key structure 500. The through design of the shaft 432 ensures that the mounting axes of multiple key units 510 are consistent, effectively avoiding problems such as jamming and offset when the key rotates. This ensures that the key unit 510 can move smoothly and accurately between the closed and open positions. When a single key unit 510 malfunctions, it can be directly repaired or replaced without disassembling the entire key structure 500 or the tube body, further simplifying the maintenance process and reducing maintenance costs.

[0049] In this embodiment, the key unit 510 includes a torsion spring 511 and a key body 512. The torsion spring 511 passes through the shaft connection portion 432a and includes a first end 511a and a second end 511b. The key body 512 passes through the shaft connection portion 432a, with the first end 511a abutting against the tube body and the second end 511b abutting against the key body 512, so that the key body 512 can be driven to open the tone hole 120 by the elastic force of the torsion spring 511.

[0050] In this design, a torsion spring 511 is inserted through the shaft connection 432a. The elastic action of the first end 511a of the torsion spring 511 abutting against the tube body and the second end 511b abutting against the key body 512 drives the key body 512 to open the tone hole 120, thus achieving the automatic reset function of the key structure 500. When the player releases the key, no additional operation is required to quickly return the key to the open position, ensuring that the tone hole 120 is connected to the airflow channel in a timely manner. This avoids tone distortion or pitch deviation caused by delayed key reset. The elastic force of the torsion spring 511 is stable and durable, providing uniform support to the key body 512. This ensures both the tight seal between the key and the tone hole 120 when the key is in the closed position, preventing airflow leakage from affecting the sound production, and avoiding problems such as jamming or loosening when the key rotates, thus extending the service life of the key structure 500. An insertion hole is provided on the tube body, and the second end 511b is inserted into the insertion hole.

[0051] Preferably, the lateral peripheral surface of the end of the whistle 230 is provided with a plugging flange 231 extending outward along its outer side, so that the end of the whistle 230 can be detachably plugged into the plugging groove by inserting the plugging flange 231 from the opening into the plugging groove.

[0052] The reed 230 features an outwardly protruding insertion flange 231 on its end peripheral surface. This flange allows the reed 230 to be detachably inserted into the mouthpiece 200 via the insertion groove of the mouthpiece 200. This enhances the connection stability between the reed 230 and the insertion groove. The insertion flange 231 fits tightly against the inner wall of the insertion groove, effectively preventing the reed 230 from loosening, shifting, or even falling off during performance due to airflow impact, key vibration, or handling. This ensures the stability and consistency of the reed 230's vibration, thereby guaranteeing the pitch accuracy and tone purity of the saxophone. The design of the insertion flange 231 also reduces the difficulty of installing the reed 230.

[0053] In this embodiment, a thumb seat 700 is also included, which is mounted on the inner tube by means of a second outer tube structure 600.

[0054] The above description represents the preferred embodiments of the present invention. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principles of the present invention, and these improvements and modifications are also considered to be within the scope of protection of the present invention.
