Description

Technical Field

[0001] This utility model relates to the field of musical instrument technology, and in particular to a saxophone. Background Technology

[0002] The saxophone is a woodwind instrument, typically made of brass, giving it characteristics of brass instruments. As a unique and highly expressive instrument, the saxophone is widely used in the global music scene. It combines the mellowness of woodwind instruments with the loudness of brass instruments, and can excellently perform various music styles such as classical, jazz, and pop, making it a favorite among musicians and music lovers.

[0003] However, the existing saxophones have a relatively complex structure and assembly process, requiring high precision and taking a long time to assemble. After the saxophone is manufactured, its structure is relatively fixed. Users usually do not have the environmental conditions, professional tools, or knowledge to disassemble and assemble the saxophone. After the user finishes playing or after it has been idle for a period of time, dirt will appear inside and outside the instrument. The overall structure of the saxophone is inconvenient for users to clean, which affects the lifespan of the saxophone and results in a poor user experience, failing to meet user needs. Utility Model Content

[0004] The purpose of this utility model is to provide a saxophone that solves the technical problems of complex structure and inconvenience in cleaning existing saxophones.

[0005] To achieve the above objectives, the present invention provides a saxophone, comprising:

[0006] The instrument has an air cavity inside, a sound hole is opened on the upper tube wall, and the instrument has a first open end and a second open end. A mouthpiece assembly is detachably installed at the first open end, and a horn is detachably installed at the second open end.

[0007] The upper housing is detachably mounted on the outer peripheral surface of the upper tube wall of the instrument tube. The outer side of the upper housing is provided with a key structure corresponding to the tone hole, so that the corresponding tone hole can be closed by pressing the key structure.

[0008] A first hoop ring is detachably fitted onto one end of the upper housing;

[0009] The second hoop ring is detachably fitted onto the other end of the upper housing so that the two ends of the upper housing can be installed to the outer peripheral surface of the upper tube wall of the instrument tube through the first hoop ring and the second hoop ring respectively.

[0010] Furthermore, the mouthpiece assembly includes a connecting tube and a mouthpiece. One end of the connecting tube is connected to the first open end, and the other end of the connecting tube is connected to one end of the mouthpiece. The connecting tube includes a first semi-annular component and a second semi-annular component that can be separated from each other. The mouthpiece assembly includes a mouthpiece, which includes a body and a reed. A reed bed is provided on one side of the body, and the reed is detachably mounted on the reed bed.

[0011] Furthermore, the sentry bed is provided with a U-shaped limiting wall, the upper surface of which extends inward to form a blocking edge, thereby forming an insertion groove between the sentry bed, the U-shaped limiting wall and the blocking edge, and the sentry plate is inserted into the insertion groove.

[0012] Furthermore, the instrument tube includes an inner tube and a lower shell. The lower shell is detachably mounted on the outer peripheral surface of the lower tube wall of the inner tube. The inner peripheral surface of the first hoop abuts against the outer peripheral surfaces of the upper shell and the lower shell, so that the first hoop fixes one end of the upper shell and one end of the lower shell to one end of the inner tube. The inner peripheral surface of the second hoop abuts against the outer peripheral surfaces of the upper shell and the lower shell, so that the second hoop fixes the other end of the upper shell and the other end of the lower shell to the other end of the inner tube.

[0013] Furthermore, the side peripheral edge of the upper shell can abut against the side peripheral edge of the lower shell, so that the upper shell and the lower shell can completely enclose the inner tube.

[0014] Furthermore, the upper shell has a first limiting step and a second limiting step formed at both ends, and the lower shell has a third limiting step and a fourth limiting step formed at both ends, so that when the upper shell and the lower shell are installed on the inner tube, the first limiting step and the third limiting step are coplanar so that one side of the first hoop abuts against each other, and the second limiting step and the fourth limiting step are coplanar so that one side of the second hoop abuts against each other.

[0015] Furthermore, the other side of the first hoop can abut against the mouthpiece assembly, and the second hoop can abut against the horn tube.

[0016] Furthermore, the side wall of the lower housing is provided with a clearance hole, and the instrument tube also includes a thumb seat, which includes a base plate and a hand grip. The base plate is installed between the inner tube and the lower housing, and the hand grip extends out of the lower housing through the clearance hole.

[0017] Furthermore, the button structure includes:

[0018] Multiple mounting seats are provided, spaced apart along the length of the upper housing to form a mounting space between adjacent mounting seats, and mounting holes are coaxially provided on the multiple mounting seats;

[0019] A shaft, which passes through the mounting hole;

[0020] Multiple flexible tone keys are rotatably mounted on the shaft, and each of the multiple flexible tone keys is installed in a corresponding manner within the mounting space.

[0021] Furthermore, the elastic key includes:

[0022] The pressing plate is rotatably connected to the shaft.

[0023] A torsion spring is sleeved on the shaft. One end of the torsion spring abuts against the pressing piece, and the other end of the torsion spring abuts against the mounting base, so that the pressing piece is driven to reset by the elastic force of the torsion spring.

[0024] As can be seen from the above technical solution, the saxophone of this utility model has tone holes on the pipe. The key structure of the saxophone is set on the upper shell, and the upper shell is installed on the pipe. The first hoop and the second hoop are respectively installed at both ends of the upper shell to fix the upper shell to the outer circumference of the pipe. Finally, the mouthpiece assembly and the horn are respectively installed at both ends of the pipe so that when the user presses the key structure, it can close the corresponding tone hole. The user can produce the corresponding note by blowing air into the pipe through the mouthpiece assembly. When disassembly and cleaning are required, the mouthpiece assembly and the horn are removed first, and the first hoop and the second hoop are removed in the direction away from the pipe. The upper shell can be removed from the pipe. The detachable structure of the upper shell and the pipe allows the user to remove the key structure at one time by disassembling the upper shell, so that the user can clean each unit of the key structure from the inside of the upper shell. The fixing structure of the first hoop and the second hoop is simple and can be quickly disassembled without tools. The simple structure and easy disassembly and assembly effectively improve the service life.

[0043] 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 utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0044] Please refer to the following: Figures 1 to 8 This embodiment provides a saxophone, including a pipe 100, an upper housing 400, a first hoop 600, and a second hoop 700. The pipe 100 has an air cavity inside, and a tone hole 110 is opened in the upper wall of the pipe 100. The pipe 100 has a first open end 120 and a second open end 130. A mouthpiece assembly 200 is detachably installed on the first open end 120, and a horn 300 is detachably installed on the second open end 130. The upper housing 400 is detachably installed on the pipe 100. The outer peripheral surface of the upper tube wall of the instrument tube 100 is provided with a button structure 500 corresponding to the tone hole 110 on the outer side of the upper shell 400, so that the corresponding tone hole 110 can be closed by pressing the button structure 500. The first hoop 600 is detachably sleeved on one end of the upper shell 400, and the second hoop 700 is detachably sleeved on the other end of the upper shell 400, so that the two ends of the upper shell 400 can be installed to the outer peripheral surface of the upper tube wall of the instrument tube 100 by the first hoop 600 and the second hoop 700 respectively.

[0045] As can be seen, in this embodiment, the saxophone has tone holes 110 on the pipe 100. The key structure 500 of the saxophone is mounted on the upper housing 400, and the upper housing 400 is installed onto the pipe 100. The first hoop 600 and the second hoop 700 are respectively installed at both ends of the upper housing 400 to fix the upper housing 400 to the outer surface of the pipe 100. Finally, a mouthpiece assembly 200 and a horn 300 are respectively installed at both ends of the pipe 100. When the user presses the key structure 500, it can close the corresponding tone hole 110. The user can produce the corresponding note by blowing air into the pipe 100 through the mouthpiece assembly 200. The saxophone can be disassembled for cleaning. During cleaning, first remove the mouthpiece assembly 200 and the horn 300, and then remove the first clamp ring 600 and the second clamp ring 700 in the direction away from the instrument tube 100. This allows the upper housing 400 to be removed from the instrument tube 100. The separable structure of the upper housing 400 and the instrument tube 100 allows the user to remove the button structure 500 in one go by disassembling the upper housing 400, making it convenient for the user to clean the various units of the button structure 500 from the inside of the upper housing 400. The fixing structure of the first clamp ring 600 and the second clamp ring 700 is simple and can be quickly disassembled without tools. The simple structure and convenient disassembly and assembly effectively improve the service life.

[0046] In this embodiment, please refer to the following: Figures 2 to 3 The outer periphery of the tone hole 110 extends upward to form an annular protruding wall. The upper housing 400 is provided with a through hole corresponding to the annular protruding wall, so that when the upper housing 400 is installed on the outer peripheral surface of the instrument tube 100, the annular protruding wall can pass through the corresponding through hole. The outer side wall of the annular protruding wall abuts against the inner side wall of the through hole. The button structure 500 includes multiple button units, each button unit corresponding to at least one tone hole 110. Pressing the button unit with a finger can close the corresponding annular protrusion. The top of the protruding wall achieves the effect of sealing the tone hole 110. The annular protruding wall also achieves precise positioning; that is, the outer diameter of the annular protruding wall matches the diameter of the through hole. When the user installs the upper housing 400 onto the outer circumferential surface of the upper tube wall of the instrument tube 100, the outer wall of the annular protruding wall abuts against the inner wall of the through hole, preventing the upper housing 400 from moving laterally. Combined with the first clamp ring 600 and the second clamp ring 700, the upper housing 400 is fixedly installed on the instrument tube 100. Compared with existing saxophones, the saxophone of this application does not require the user to disassemble each key unit and then precisely install it individually. Through the upper housing 400, the user can position and install the entire key structure 500 onto the instrument tube 100, allowing each key unit to automatically align with its corresponding tone hole 110.

[0047] The materials of the instrument tube 100, the upper shell 400, the first hoop 600, and the second hoop 700 are metal or hard plastic, preferably hard plastic.

[0048] Preferably, please refer to the following: Figures 1 to 4 The mouthpiece assembly 200 includes a connecting tube 220 and a mouthpiece 210. One end of the connecting tube 220 is connected to the first open end 120, and the other end of the connecting tube 220 is connected to one end of the mouthpiece 210. The connecting tube 220 includes a first semi-annular member 221 and a second semi-annular member 223 that can be separated from each other. The mouthpiece assembly 200 includes a mouthpiece 210, which includes a body 211 and a reed 213. A reed bed 212 is provided on one side of the body 211, and the reed 213 is detachably mounted on the reed bed 212.

[0049] It is worth noting that the connecting tube 220 and mouthpiece 210, being closest to the user's air inlet, typically accumulate the most dirt. However, due to their small inner diameter, it is difficult for users to clean the impurities adhering to their inner walls. By designing the connecting tube 220 with a relatively separable first semi-annular component 221 and a second semi-annular component 223, the inner wall of the connecting tube 220 can be exposed, allowing users to easily clean it. Furthermore, the first semi-annular component 221 and the second semi-annular component 223 can be closed to form a ring-shaped connecting tube 220 without affecting its connection to the instrument tube 100. The reed 213, as a key component for saxophone sound production, is prone to tone changes due to wear, water accumulation, or oxidation after prolonged use. The detachable design allows users to remove the reed 213 at any time for drying, cleaning, or replacement, avoiding the maintenance inconvenience caused by the fixed reed 213 in traditional integrated mouthpieces. Different pieces or playing styles may require reeds of different thicknesses or materials 213.

[0050] In addition, such as Figure 4 As shown, the first semi-annular component 221 has a plug-in post 222 on the side facing the second semi-annular component 223, and the second semi-annular component 223 has an embedding groove 224 on the side facing the first semi-annular component 221. When the first semi-annular component 221 and the second semi-annular component 223 are closed, the plug-in post 222 is inserted into the embedding groove 224, and the plug-in post 222 and the embedding groove 224 are tightly fitted so that the first semi-annular component 221 and the second semi-annular component 223 will not separate arbitrarily.

[0051] Preferably, such as Figure 4As shown, a sentry bed 212 is provided on one side of the main body 211. A U-shaped limiting wall 214 is provided on the sentry bed 212. The upper surface of the U-shaped limiting wall 214 extends inward to form a blocking edge 215, so as to form an insertion groove 216 between the sentry bed 212, the U-shaped limiting wall 214 and the blocking edge 215. The sentry piece 213 is inserted into the insertion groove 216.

[0052] The U-shaped limiting wall wraps around the reed 213 from both sides and one end, while the abutment edge 215 restricts the vertical displacement of the reed 213 from above, forming a three-sided constrained insertion groove 216. This structure prevents the reed 213 from sliding back and forth or tilting up during playing, ensuring the precise fit between the reed 213 and the reed bed 212. The insertion groove 216 design allows users to push or pull the reed 213 in or out with one hand, without the need for tools. Compared to the traditional method that requires tightening screws or adjusting clamps, this plug-and-play installation is more suitable for scenarios where the reed 213 needs to be changed quickly during a performance.

[0053] In this embodiment, please refer to the following: Figures 1 to 4 The instrument tube 100 includes an inner tube body 140 and a lower shell 150. The lower shell 150 is detachably mounted on the outer peripheral surface of the lower tube wall of the inner tube body 140. The inner peripheral surface of the first hoop 600 abuts against the outer peripheral surfaces of the upper shell 400 and the lower shell 150, so that the first hoop 600 fixes one end of the upper shell 400 and one end of the lower shell 150 to one end of the inner tube body 140. The inner peripheral surface of the second hoop 700 abuts against the outer peripheral surfaces of the upper shell 400 and the lower shell 150, so that the second hoop 700 fixes the other end of the upper shell 400 and the other end of the lower shell 150 to the other end of the inner tube body 140.

[0054] The air cavity is located within the inner tube 140, and the sound hole 110 is located on the inner tube 140. The lower shell 150 is detachably mounted on the outer peripheral surface of the lower tube wall of the inner tube 140, and the upper shell 400 is detachably mounted on the outer peripheral surface of the upper tube wall of the inner tube 140, so that the upper shell 400 and the lower shell 150 together enclose the inner tube 140 to provide protection for the inner tube 140. The lower shell 150 and the upper shell 400 can be fixedly mounted to the outer surface of the inner tube 140 by the first hoop 600 and the second hoop 700. The fixing method of the first hoop 600 and the second hoop 700 is simple and convenient, and users can quickly disassemble and install the upper shell 400 and the lower shell 150.

[0055] Furthermore, the side periphery of the upper shell 400 can abut against the side periphery of the lower shell 150, so that the upper shell 400 and the lower shell 150 can completely enclose the inner tube 140. Both the upper shell 400 and the lower shell 150 are semi-circular annular structures. The side periphery of the upper shell 400 and the lower shell 150 abut against each other to form an annular enclosure of the inner tube 140. During maintenance, only the hoop needs to be removed to separate the upper shell 400 and the lower shell 150 and expose the outer surface of the inner tube 140.

[0056] Furthermore, please refer to the following: Figures 1 to 4 The upper housing 400 has a first limiting step 420 and a second limiting step 430 formed at both ends, and the lower housing 150 has a third limiting step 151 and a fourth limiting step 152 formed at both ends, so that when the upper housing 400 and the lower housing 150 are installed on the inner tube 140, the first limiting step 420 and the third limiting step 151 are coplanar so that one side of the first hoop 600 abuts against each other, and the second limiting step 430 and the fourth limiting step 152 are coplanar so that one side of the second hoop 700 abuts against each other.

[0057] The first limiting step 420 and the third limiting step 151 are coplanar after being engaged, forming a flat first abutment surface. The second limiting step 430 and the fourth limiting step 152 are coplanar after being engaged, forming a flat second abutment surface. One side of the first hoop 600 can abut against the first abutment surface, and one side of the second hoop 700 can abut against the second abutment surface. This design can ensure that the upper shell 400 and the lower shell 150 are fixed in the z-direction through physical limiting, avoiding gaps or offsets caused by misalignment during installation, and ensuring the stability of the overall structure. The first hoop 600 is tightly fitted with the upper shell 400 and the lower shell 150, and the second hoop 700 is also tightly fitted with the upper shell 400 and the lower shell 150, so that the first hoop 600 and the second hoop 700 are not easy to accidentally fall off outward along the length direction.

[0058] Furthermore, the other side of the first hoop 600 can abut against the mouthpiece assembly 200, and the second hoop 700 can abut against the horn 300. The mouthpiece assembly 200 and the horn 300 can be detachably installed onto the instrument 100 using existing limiting structures, snap-fit ​​connections, or screws. By abutting the other side of the first hoop 600 against the mouthpiece assembly 200 and the second hoop 700 against the horn 300, the first hoop 600 and the second hoop 700 are further limited.

[0059] Furthermore, the lower housing 150 has a clearance hole 153 on its side wall. The instrument tube 100 also includes a thumb seat 160, which includes a base plate 161 and a handheld part 162. The base plate 161 is installed between the inner tube 140 and the lower housing 150. The handheld part 162 protrudes from the lower housing 150 through the clearance hole 153. The thumb seat 160 provides a handheld space for the user. The outer surface of the bottom of the inner tube 140 has an elongated groove. The thumb seat 160 is slidably installed in the elongated groove. Multiple positioning protrusions are provided along the length of the elongated groove. The base plate 161 has a positioning groove on the side facing the inner tube 140. This allows the sliding thumb seat 160 to engage with different positioning protrusions and positioning grooves. Installing the lower housing 150 allows the thumb seat 160 to be fixed in different positions to accommodate different users' finger sizes. It is worth mentioning that the disassembly structure of the technical solution of this application allows the user to easily adjust the thumb seat 160.

[0060] In this embodiment, please refer to the following: Figures 1 to 8 The button structure 500 includes multiple mounting seats 510, shafts 520, and multiple resilient tone keys 530. The multiple mounting seats 510 are spaced apart along the length of the upper housing 400 to form an installation space 540 between adjacent mounting seats 510. The multiple mounting seats 510 are coaxially provided with mounting holes, and the shafts 520 pass through the mounting holes. The multiple resilient tone keys 530 are rotatably mounted on the shafts 520, and the multiple resilient tone keys 530 are installed one-to-one in the installation space 540. The mounting seats 510 and the upper housing 400 are integrally formed, and the shafts 520 are cylindrical rods. The button structure 500 with this configuration is simple and easy to manufacture.

[0061] Furthermore, please refer to the following: Figures 1 to 8 The elastic key 530 includes a pressing plate 531 and a torsion spring 532. The pressing plate 531 is rotatably connected to the shaft 520. The torsion spring 532 is sleeved on the shaft 520. One end of the torsion spring 532 abuts against the pressing plate 531, and the other end of the torsion spring 532 abuts against the mounting base 510, so that the pressing plate 531 is driven to reset by the elastic force of the torsion spring 532. The elastic force of the torsion spring 532 can drive the pressing plate 531 to quickly reset after it is pressed. The design structure of the torsion spring 532 sleeved on the shaft 520 is simple, and the reset function can be realized without complex drive components, reducing manufacturing and assembly costs.

[0062] Specifically, please refer to the following: Figures 1 to 8The press plate is provided with a receiving cavity and an abutment groove communicating with the receiving cavity. An insertion groove is provided on the upper housing 400 at the installation space 540. By installing the torsion spring 532 into the receiving cavity and the press plate into the installation space 540, one end of the torsion spring 532 abuts against the abutment groove and the other end of the torsion spring 532 is inserted into the insertion groove. Finally, the shaft 520 is inserted to complete the assembly. The shaft 520 can be fixed to the mounting base 510 by welding, bonding or other methods.

[0063] As can be seen from the above description, the embodiments of this utility model achieve the following technical effects:

[0064] A tone hole 110 is provided on the saxophone tube 100. The saxophone key structure 500 is mounted on the upper housing 400, and the upper housing 400 is then installed onto the tube 100. A first clamp ring 600 and a second clamp ring 700 are respectively installed at both ends of the upper housing 400 to fix the upper housing 400 to the outer surface of the tube 100. Finally, a mouthpiece assembly 200 and a horn tube 300 are respectively installed at both ends of the tube 100. When the user presses the key structure 500, it closes the corresponding tone hole 110. The user blows air into the tube 100 through the mouthpiece assembly 200 to produce the corresponding note. For disassembly and cleaning, the mouthpiece should be removed first. By removing component 200 and horn 300, and removing the first clamp 600 and the second clamp 700 respectively in the direction away from the instrument tube 100, the upper housing 400 can be removed from the instrument tube 100. The separable structure of the upper housing 400 and the instrument tube 100 allows the user to remove the button structure 500 in one go by disassembling the upper housing 400, making it convenient for the user to clean the various units of the button structure 500 from the inside of the upper housing 400. The fixing structure of the first clamp 600 and the second clamp 700 is simple and can be quickly disassembled without tools. The simple structure and convenient disassembly and assembly effectively improve the service life.
