Description

Technical Field

[0001] This application relates to the field of musical instrument auxiliary equipment technology, specifically an air volume adjustment device for a brass instrument mouthpiece practice device. Background Technology

[0002] Brass instruments are instruments that vibrate the lips by blowing air into a mouthpiece. They are also called "labrosones," which literally means "instruments that vibrate the lips" (Baines). To change the pitch on a keyed instrument, there are two methods: first, pressing down a key changes the length of the tube; second, the airflow blown by the player changes the frequency of lip vibration.

[0003] When learning brass instruments, students practice blowing the mouthpiece alone. However, blowing only the mouthpiece provides no resistance and cannot achieve the same effect as placing the mouthpiece on the instrument. To more closely resemble the effect of blowing the instrument, a structure that can assist in changing the air resistance of the mouthpiece is needed. Current technology lacks such an easy-to-use structure to assist in blowing practice, which has certain shortcomings.

[0004] Therefore, this application provides an air volume adjustment device for a brass instrument mouthpiece practice device to solve the above-mentioned problems. Utility Model Content

[0005] This application provides an air volume adjustment device for a brass instrument mouthpiece practice device, aiming to solve the problems mentioned in the background art, such as the lack of a structure that can assist in adjusting the blowing resistance of the practice mouthpiece.

[0006] To achieve the above objectives, this application provides the following technical solution: an air volume adjustment device for a brass instrument mouthpiece practice device, comprising a support for connecting the mouthpiece practice device and an adjustment part rotatably mounted on the support at an end away from the mouthpiece practice device. The support part is cylindrical in design, and air passages for airflow are distributed along its length inside the support part. The air passages pass through the end of the support part. The mouthpiece trainer is inserted into one end of the air passage and communicates with the air passage. The adjustment part is rotatably installed on the end of the air passage away from the mouthpiece trainer. The adjusting part is a cap-shaped closed structure. An air valve communicating with the air passage is opened on the outer wall of the supporting part near one end. A retaining ring adapted to the air passage is fixedly installed on the adjusting part, and an air vent adapted to the air valve is opened on the retaining ring. Thus, in use, the mouthpiece trainer is inserted into the air passage at one end of the supporting part through its long tube. Then, the adjusting part is inserted into the other end of the supporting part, sealing the other end of the air passage. By rotating the adjusting part, the retaining ring rotates within the air passage. When the air vent on the retaining ring is completely aligned with the air valve on the supporting part, the air valve is at its maximum opening, and the blowing resistance is minimal. When the air vent on the retaining ring is completely misaligned with the air valve on the supporting part, the blowing resistance is maximum. By rotating the adjusting part to change the overlap range of the air vent and the air valve, the opening and closing degree of the air valve is changed, thereby adjusting the blowing resistance to assist in practice and effectively improve the practice effect.

[0007] Preferably, in order to improve sealing, the air passage has a variable diameter structure, and the diameter of the air passage gradually increases from the end near the nozzle trainer to the end near the adjustment part. A rubber gasket for sealing the end of the nozzle trainer is fixedly installed on the inner side wall of the air passage at the middle variable diameter section, thereby expanding the adjustment area of ​​the valve to provide more adjustment options.

[0008] Preferably, for ease of operation, the maximum outer diameter of the adjusting part is adapted to the maximum outer diameter of the supporting part, the supporting part has a wave-shaped grip part along the length direction, and the outer side wall of the adjusting part has anti-slip grooves distributed in a ring array to improve the ease of operation.

[0009] Preferably, to facilitate determining the degree of opening and closing, a limiting piece is fixedly installed on one end of the vent on the retaining ring, and the outer wall surface of the limiting piece coincides with the outer wall surface of the support part, so as to facilitate the user to determine the degree of valve opening and closing.

[0010] Preferably, for easy identification, an indicator for indicating the valve opening degree is provided on the outer wall of the support at the valve. The indicator is designed to correspond to the movement trajectory of the limit piece, making it easy for the user to recognize and operate.

[0011] Preferably, for ease of connection, the support part has an annular groove on the inner side wall of the air passage near the adjustment part, and the retaining ring is fixedly installed with a locking protrusion that matches the groove. The locking protrusion engages with the groove to prevent accidental dislodgement and improve connection stability without affecting the rotation effect.

[0012] Preferably, for ease of disassembly, the retaining ring has a clearance opening at a position different from the vent, which facilitates disassembly and fixing.

[0013] This air volume adjustment device involves inserting the mouthpiece trainer into the airway at one end of the support unit through its long tube, and then inserting the adjustment unit into the other end of the support unit to block the other end of the airway. By rotating the adjustment unit, the retaining ring rotates within the airway. When the air vent on the retaining ring is completely aligned with the valve on the support unit, the valve is at its maximum opening, resulting in minimal blowing resistance. When the air vent on the retaining ring is completely misaligned with the valve on the support unit, the blowing resistance is at its maximum. By rotating the adjustment unit to change the overlap range between the air vent and the valve, the opening and closing degree of the valve is altered, thereby adjusting the blowing resistance to assist in practice and effectively improve the training effect.

[0014] This air volume regulating device inserts the regulating part into the air passage end of the support part through a retaining ring. By pushing the regulating part, the locking protrusion on the retaining ring can be stably locked into the locking groove on the inner wall of the air passage, thereby completing the connection between the support part and the regulating part, preventing accidental dislodgement, and improving the connection stability without affecting the rotation effect.

[0017] 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 some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0018] Example 1 This embodiment provides an airflow adjustment device for a brass instrument mouthpiece practice device, such as... Figure 1-6 As shown, the air volume regulating device includes a support part 2 for connecting the mouthpiece trainer 1, and an adjusting part 3 rotatably mounted on the support part 2 at the end away from the mouthpiece trainer 1. The support part 2 is cylindrical in shape. An air passage 21 for airflow is provided inside the support part 2 along its length. The air passage 21 passes through the end of the support part 2. The mouthpiece trainer 1 is inserted into one end of the air passage 21 and communicates with the air passage 21. The adjustment part 3 is rotatably installed on the end of the air passage 21 away from the mouthpiece trainer 1. The adjustment part 3 is a closed structure in the shape of a cover. On the outer side wall of the support part 2, a valve 22 communicating with the air passage 21 is opened at one end near the adjustment part 3. A retaining ring 31 adapted to the air passage 21 is fixedly installed on the adjustment part 3. An air vent 32 adapted to the valve 22 is opened on the retaining ring 31.

[0019] In use, the mouthpiece trainer 1 is inserted into the airway 21 at one end of the support part 2 through its long tube. Then, the adjusting part 3 is inserted into the other end of the support part 2 to block the other end of the airway 21. By rotating the adjusting part 3, the retaining ring 31 rotates within the airway 21. When the air vent 32 on the retaining ring 31 is completely aligned with the valve 22 on the support part 2, the valve 22 is at its maximum opening degree, and the blowing resistance is minimal. When the air vent 32 on the retaining ring 31 is completely misaligned with the valve 22 on the support part 2, the blowing resistance is maximum. By rotating the adjusting part 3 to change the overlap range between the air vent 32 and the valve 22, the opening degree of the valve 22 can be changed, thereby adjusting the blowing resistance to assist in practice and effectively improve the practice effect.

[0020] Specifically, the airway 21 has a variable diameter structure. The diameter of the airway 21 gradually increases from the end near the nozzle trainer 1 to the end near the adjustment part 3. A rubber gasket 23 for sealing the end of the nozzle trainer 1 is fixedly installed on the inner wall of the airway 21 at the middle variable diameter section.

[0021] In use, the variable-diameter air passage 21 can be adapted to the long tube of the commonly used mouthpiece training device 1, while also facilitating the adaptation to the enlarged adjustment section 3, thereby increasing the adjustment area of ​​the valve 22 and providing more adjustment options.

[0022] It is understandable that, due to the limitations of the precision of the processing equipment, there may be gaps at the end of the metal mouthpiece trainer 1 when it comes into contact with the smooth inner wall of the air passage 21, which affects the sealing performance during blowing. By setting an annular rubber gasket 23 inside the air passage 21, the end of the mouthpiece trainer 1 can abut against the rubber gasket 23 after being inserted into the air passage 21 to achieve a relative seal, thereby improving the blowing stability.

[0023] More specifically, the maximum outer diameter of the adjusting part 3 is adapted to the maximum outer diameter of the supporting part 2, the supporting part 2 is provided with a wave-shaped gripping part 24 along the length direction, and the outer side wall of the adjusting part 3 is provided with anti-slip grooves 33 distributed in a ring array.

[0024] When in use, the grip part 24 allows the user to easily hold the support part 2 during practice, and the anti-slip groove 33 allows the user to easily rotate the adjustment part 3 during practice, improving the ease of operation.

[0025] Furthermore, a limiting piece 34 is fixedly installed on the retaining ring 31 at one end of the vent 32, and the outer wall surface of the limiting piece 34 coincides with the outer wall surface of the support part 2.

[0026] When in use, the air vent 32 and valve 22 are aligned by the limiting plate 34 when the adjusting part 3 is rotated, so that the overlapping of the air vent 32 and valve 22 can be understood by directly observing the limiting plate 34, making it convenient for the user to determine the degree of opening and closing of valve 22.

[0027] Furthermore, an indicator 25 for indicating the degree of valve opening is provided on the outer wall of the support 2 at the valve 22, and the indicator 25 is designed to correspond to the movement trajectory of the limit piece 34.

[0028] When using the valve 22, the adjustment part 3 can be rotated by observing the indicator part 25 on the outer wall of the support part 2, so that the limit piece 34 rotates clockwise or counterclockwise in accordance with the indicator part 25, making it easy for the user to recognize and operate.

[0029] Example 2 Unlike Embodiment 1, if the retaining ring 31 is directly inserted into the air passage 21 and rotated, it is easy to fall out and the stability is poor. Therefore, the support part 2 has a ring-shaped groove 26 on the inner side wall of the air passage 21 near the adjustment part 3. The retaining ring 31 is fixedly installed with a locking protrusion 35 that matches the groove 26, and the locking protrusion 35 engages with the groove 26.

[0030] In use, the adjustment part 3 is inserted into the end of the air passage 21 of the support part 2 through the retaining ring 31. By pushing the adjustment part 3, the locking protrusion 35 on the retaining ring 31 can be stably locked into the locking groove 26 on the inner wall of the air passage 21, thereby completing the engagement of the support part 2 and the adjustment part 3, preventing accidental dislodgement, and improving the connection stability without affecting the rotation effect.

[0031] Furthermore, the retaining ring 31 has a clearance opening 36 at a position different from the vent 32.

[0032] It is understandable that when inserting or removing the adjustment part 3, the clearance port 36 can provide a retraction space for the retaining ring 31, thereby allowing the locking protrusion 35, which is inserted into the locking groove 26, to move at the end of the air passage 21, making it convenient to disassemble and fix.

[0033] The above description is merely a preferred embodiment of this application, but the scope of protection of this application is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in this application, based on the technical solution and concept of this application, should be included within the scope of protection of this application.
