After long-term practice, the practitioner will develop muscle memory for actively lifting the finger. In actual playing, even without the spring's assistance, the finger can be actively and quickly lifted, ensuring the timeliness and accuracy of key presses and avoiding problems such as slow key presses, unstable pitch, key slips, or missed notes.

Description

Technical Field

[0001] This utility model relates to the field of trumpet instrument technology, specifically to a fingering practice aid for trumpet instruments. Background Technology

[0002] The trumpet, as an important brass instrument, occupies an important position in the field of music performance. Its performance effect largely depends on the player's precise and flexible fingering. For trumpet learners, effective fingering practice is crucial.

[0003] In the prior art, such as the fingering practice aid for a trumpet disclosed in application number 202323642483.9, through the design of a hollow column, a movable block, a connecting rope, a spring, a pull ring, and an adjusting screw, the learner can pass his fingers through the pull ring to play when using the trumpet. When the learner's fingers press or release the keys on the trumpet, the spring will be compressed or released, and the learner can feel greater resistance when pressing the keys.

[0004] However, in the application document disclosed under application number CN202123314619.4, when the finger releases the key, the upward pull of the spring forces the finger to be passively lifted. After long-term practice, the practitioner will rely on this external force assistance and gradually form the wrong muscle memory that the finger does not need to be actively lifted. When actually playing the trumpet, without the assistance of the spring, the practitioner may forget to actively lift the finger, resulting in slow key action, unstable pitch, or even slipping or missing notes.

[0005] In view of the above, this application is hereby submitted. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1-4This utility model provides a technical solution: a fingering practice aid for a trumpet, including a sleeve 2, a fixed plate 9 fixedly installed on the inner wall of the sleeve 2, and a sliding connection between the outer wall of the pressing column 4 and the inner wall of the sleeve 2, ensuring that the pressing column 4 can move stably in the vertical direction, making the pressing operation more precise and effectively avoiding deviation or shaking. A locking rod 10 is rotatably installed on the side wall of the fixed plate 9, and the top of the locking rod 10 is slidably installed on the pressing column 4. A sliding chamber 5 is also provided on the outer wall of the pressing column 4, and the bottom of the inner wall of the sliding chamber 5 is fixedly installed with... The device has a bottom plate 6, a thin plate 14 fixedly installed at its center, a thick plate 13 fixedly installed on the side wall of the thin plate 14, a guide plate 12 fixedly installed on the side wall of the thick plate 13, and a top plate 15 fixedly installed on the top of the inner wall of the sliding chamber 5. The bottom vertical point of the top plate 15 corresponds to the midpoint of the top of the thin plate 14. The user only needs to insert their fingers into the finger sleeves 3 and press down or lift the finger sleeves 3 to move the pull rod 16 and the pressing rod 7 synchronously, thus realizing the pressing and releasing operation of the small button. The top of the pressing rod 7 is fixedly installed with the pull rod 16. The finger sleeve 3 is fixedly installed. The outer wall of the pressure rod 7 is slidably connected to the pressure column 4 and the inner wall of the fixed plate 9. The bottom of the fixed plate 9 is connected to the spring 20 via the second fixing ring 19. The bottom of the spring 20 is connected to the first fixing ring 11. The pressure rod 7 is fixedly installed on the inner wall of the first fixing ring 11. When the finger sleeve 3 is pressed, the pressure column 4 moves downward to compress the pressure spring 8. The bottom of the pressure spring 8 is fixedly connected to the top of the fixed plate 9. The resistance it provides can enhance the force of finger pressing, helping the practitioner to exercise finger muscles and improve finger strength. During the pressing process, when When the button is fully pressed, the top of the lever 10 abuts against the connection between the thin plate 14 and the thick plate 13, forming a temporary lock to prevent the pressing column 4 and the pressing rod 7 from rebounding. This locking mechanism provides the practitioner with clear feedback on whether the button is fully pressed, allowing the practitioner to clearly perceive whether the button is fully pressed. During the release process, when the finger is lifted, the spring 20 is compressed, generating muscle memory of lifting. This two-way spring resistance mechanism can comprehensively train the pressing and lifting power of the fingers, helping the practitioner to enhance the overall strength of the fingers.

[0026] Please see Figure 3This utility model provides a technical solution: a fingering practice aid for a trumpet, including a slot 18 on the top of the inner wall of a sliding chamber 5, and the inner wall of the slot 18 can be slidably connected to the outer wall of the top of a lever 10, so that when the top of the lever 10 moves in the sliding chamber 5, it can slide precisely along the slot 18, providing a clear track for the movement of the lever 10. The length of the top of the lever 10 exceeds the width of the inner wall of the slot 18 by 5mm, ensuring that the top of the lever 10 can fully contact the inner wall of the slot 18 during the sliding process, reducing shaking and offset, and when it is necessary to engage, the excess length has enough length to enter the engagement position, ensuring the firmness and reliability of the engagement. The outer wall width of the thin plate 14 exceeds the outer wall width of the thick plate 13 by 5mm, and the connection between the thin plate 14 and the thick plate 13 is concave, and the connection between the thick plate 13 and the thin plate 14 can engage with the outer wall of the top of the lever 10, further enhancing the stability and accuracy of the engagement.

[0027] Please see Figure 3 This utility model provides a technical solution: a fingering practice aid for a trumpet, including a lever 16 made of stainless steel. Stainless steel has high strength, which ensures that the lever 16 is not easily deformed or broken even when frequently subjected to the pulling and pressure from the fingers passing through the finger sleeves 3 during long-term use. This ensures the reliability and durability of the device and effectively reduces the maintenance and replacement costs caused by damage to the lever 16. The top of the lever 16 is connected to the outer wall of the finger sleeve 3 by screws. This connection method is simple to operate. When it is necessary to install or replace the finger sleeves 3, the practitioner only needs to use appropriate tools to tighten or loosen the screws to easily complete the operation, which is convenient and efficient.

[0028] Please see Figure 2 , Figure 3 This utility model provides a technical solution: a fingering practice aid for a trumpet, including a sleeve 2 with an adhesive ring at the bottom. The practitioner can easily fix the sleeve 2 in a suitable position on the trumpet body 1 without complicated operations. The bottom of the sleeve 2 is adhered to the outer wall of the trumpet body 1 through the adhesive ring, and the inner wall of the bottom of the sleeve 2 is slidably connected to the outer wall of the keys on the outer wall of the trumpet body 1, ensuring the convenience of the sleeve 2 installation and the smoothness of subsequent key operations.

[0029] Please see Figure 3This utility model provides a technical solution: a fingering practice aid for a trumpet, including a pressing rod 7 whose bottom is perpendicularly aligned with the key on the outer wall of the trumpet body 1. This allows the pressing rod 7 to directly and accurately apply pressure to the key during operation, ensuring the precision of the pressing action and improving practice effectiveness. Considering that the metal pressing rod 7 may wear down the key surface due to direct contact with the key during frequent key presses, a rubber pad is provided at the bottom of the pressing rod 7. The rubber pad has good elasticity and flexibility, which can absorb some of the impact force when the pressing rod 7 presses the key, reducing the hard collision between the pressing rod 7 and the key, thereby effectively reducing the wear of the key and extending its service life.

[0030] Please see Figure 3 This utility model provides a technical solution: a fingering practice auxiliary device for a trumpet, including a groove 17 on the inner wall of a pressing rod 4, and the inner wall of the groove 17 is slidably connected to the outer wall of the pressing rod 7, providing a clear track for the movement of the pressing rod 7, ensuring that the pressing rod 7 can move stably along a predetermined direction during the pressing operation, and effectively avoiding the impact on the accuracy of key pressing due to movement deviation.

[0031] Working principle: The device is fixed to the button on the outer wall of the small body 1 using adhesive rings, ensuring that the inner wall of the bottom of the sleeve 2 is slidably connected to the outer wall of the button on the small body 1. The user inserts their finger into the finger sleeve 3 and begins to press down on the finger sleeve 3. The finger sleeve 3 drives the pull rod 16 and the pressing column 4 to move downwards simultaneously. During the downward movement of the pressing column 4, the pressing spring 8 is compressed. At the same time, the pressing rod 7 moves downwards with the pressing column 4, and its bottom rubber pad contacts and presses down the small button. The top of the locking rod 10 slides upwards along the inner wall of the sliding chamber 5 and enters the inclined surface of the thin plate 14. The downward movement of the pressing rod 7 causes the fixing ring 11 to move downwards, stretching the spring 20. When the button is fully pressed down, the pressing spring 8 is fully compressed, providing maximum resistance and enhancing the stability and force of the finger pressing. Spring 20 returns to its initial state, and the trumpet keys are fully pressed down. At this time, the top of the lever 10 abuts against the connection between the thin plate 14 and the thick plate 13, forming a temporary lock to prevent the pressing post 4 and the pressing rod 7 from rebounding. When releasing, the finger first slightly presses the finger sleeve 3, causing the top of the lever 10 to separate from the connection between the thin plate 14 and the thick plate 13. The finger sleeve 3 lifts up, causing the pull rod 16 and the pressing rod 7 to move upward. The upward movement of the pressing rod 7 pushes the top of the lever 10 out of the slot 18. Guided by the top plate 15, the lever 10 enters the guide plate 12 and slides along its surface to the groove of the bottom plate 6. The pressing spring 8 returns to its elastic deformation, pushing the pressing post 4 upward. Because the finger compresses spring 20 when it lifts up, the finger will develop an upward muscle memory when it releases. The practitioner repeats the above pressing and releasing operation to continuously strengthen finger strength, improve key stability, and thus improve trumpet playing level.

[0032] The above description is merely an embodiment of this utility model and does not limit the patent scope of this utility model. Any equivalent structural or procedural transformations made based on the content of this utility model specification and drawings, or direct or indirect applications in other related technical fields, are similarly included within the patent protection scope of this utility model.
