Description

Technical Field

[0001] The present invention relates to the technical field of music training auxiliary devices, and particularly to a music vocal training auxiliary device. Background Art

[0002] Music vocal training refers to the training process that helps learners master scientific vocalization techniques, enhance music expressiveness, improve sound quality, and cultivate good singing abilities through systematic teaching and practice methods. It covers the cultivation of multiple skills such as sound production, resonance, intonation, timbre, rhythm, and emotional expression, aiming to enable learners to sing songs or make music expressions with beautiful voices, accurate intonation, and infectious performances.

[0003] In vocal singing, breathing is the basis for sound production, and breath is the key driving force to promote the vibration of vocal cords and form sound. Through breathing training, learners can master the techniques of inhalation and exhalation and maintain a stable output of breath. However, in the actual singing process, there are significant differences in the breathing requirements for songs with different rhythms and styles. For example, when singing fast-paced songs, the amount of breath needs to be adjusted quickly and frequently to adapt to the rhythm changes of the songs; while when singing slow-paced songs or long notes, more breath support is required to maintain the coherence and stability of the sound. Most of the existing breathing training devices can only provide static breathing training modes and are difficult to meet the breathing training needs of trainees in dynamic singing scenarios.

[0004] In addition, the breathing abilities, physical conditions, and training goals of different trainees are different. The existing vocal training auxiliary devices are relatively single in function and lack personalized and targeted designs, making it difficult to adapt to diverse breathing training needs.

Detailed implementation manners

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0036] Please refer to Figures 1 to 9 , the present invention provides a technical solution: a music vocal training assistance device, including a base 1 and an air return cylinder 8 provided thereon for breathing training, and a variable air mechanism for dynamically adjusting the intake air volume of breathing training is provided on the base 1;

[0037] The variable air mechanism includes a horizontal shaft 2 rotatably fixed on the base 1, an air compression column 7 that moves freely horizontally above the horizontal shaft 2, a circular hole is opened on the base 1 for the air compression column 7 to slide through, the end of the air compression column 7 is fixedly connected to a piston plate 10, and the outer peripheral surface of the piston plate 10 is in sliding contact with the inner wall of the air return cylinder 8;

[0038] A horizontal component for driving the air compression column 7 to reciprocate horizontally is provided on the base 1, and a variable displacement component for adjusting the horizontal displacement amount of the air compression column 7 in a single movement cycle is also provided on the base 1;

[0039] Two groups of comb-shaped seats 26 are fixedly connected to the base 1, and a sound reminder component for exhaling and inhaling reminders during breathing training is provided on the two groups of comb-shaped seats 26.

[0040] A sealing ring 9 is fixedly connected to the air return cylinder 8. The sealing ring 9 is fixedly sleeved on the outer peripheral surface of the air return cylinder 8. A fork-shaped pipe 11 is fixedly penetrated through the air return cylinder 8. The fork-shaped pipe 11 includes an integrally formed air inlet end 111 and a flared end 12. A nozzle 13 is inserted and fixed on the flared end 12.

[0041] As Figure 1 , Figure 3 and Figure 5 shown, in vocal music singing, breathing is the basis for sound production, and breath is the key driving force to push the vocal cords to vibrate and form sound. Therefore, through breathing training, learners can master the skills of inhaling and exhaling and maintain a stable output of breath. Among them, when the trainee has undergone breathing training, the disposable nozzle 13 is inserted into the flared end 12, and the displacement of the air compression column 7 in the horizontal direction is adjusted first through the displacement component, that is, the single intake volume during breathing training is adjusted. Furthermore, personalized training settings can be made according to the individual differences of the trainees. Since the breathing abilities, physical conditions, and training goals of different trainees are different, by adjusting the intake volume of each breath, the most suitable training plan can be provided for each trainee.

[0042] At the same time, after the single intake volume is adjusted, the trainee holds the end of the nozzle 13 away from the flared end 12 in the mouth, and then the horizontal component drives the air compression column 7 to reciprocate in the horizontal direction, so that the piston plate 10 fixedly arranged at the end drives the piston plate 10 to move in the air return cylinder 8. Thus, when the piston plate 10 moves towards the fork-shaped pipe 11, the gas in the air return cylinder 8 can be pushed to flow from the flared end 12 to the nozzle 13, and the gas is sent into the trainee's respiratory tract through the nozzle 13.

[0043] Among them, one-way valves are provided on both the air inlet end 111 and the flared end 12, and the valve ports of the two groups of one-way valves are in opposite directions. Therefore, when the piston plate 10 reciprocates in the air return cylinder 8, the gas in the air return cylinder 8 can be driven to be sent into the trainee's respiratory tract through the flared end 12. At the same time, when the piston plate 10 moves away from the fork-shaped pipe 11, natural air can be supplemented into the air return cylinder 8 through the air inlet end 111. Moreover, during the process of the piston plate 10 moving away from the fork-shaped pipe 11, the exhalation time can be provided for the trainee, thereby completing a breathing process.

[0044] At the same time, by setting a sound awakening component on the two comb-shaped seats 26, when the piston plate 10 is at the end position of a single reciprocating motion stroke, the trainee can be reminded of the end of the exhalation or inhalation process through a specific impact sound. The impact sound can provide a clear breathing node for the trainee, helping them clearly perceive the start and end of each breath. This clear reminder can help the trainee better master the rhythm of breathing and avoid hesitation or unnatural pauses during the breathing process.

[0045] It should be noted that during actual use, the horizontal component and the displacement-changing component can operate synchronously. That is, when the horizontal component drives the piston plate 10 to reciprocate in the air return cylinder 8, under the drive of the displacement-changing component, the displacement of the piston plate 10 in the air return cylinder 8 can be continuously and dynamically adjusted. Furthermore, it can simulate the changes in breathing demands in songs with different rhythms, helping trainees practice flexibly adjusting the breathing volume between different rhythms. At the same time, during the breathing training process, dynamically changing the air supply volume can enable the breathing muscles of the trainees to continuously adapt to different breathing intensities. This dynamic adjustment can effectively exercise the flexibility and endurance of the breathing muscles, enabling trainees to control their breathing more flexibly during actual singing.

[0046] In one relatively preferred embodiment, the horizontal shaft 2 includes an integrally formed spline portion 201. The horizontal component includes a driving industrial work disk 3 slidably sleeved on the spline portion 201 and a driven industrial work disk 4 rotatably fixed on the horizontal shaft 2. A connecting rod 5 is provided between the driving industrial work disk 3 and the driven industrial work disk 4, and both ends of the connecting rod 5 are rotatably fixed on the driving industrial work disk 3 and the driven industrial work disk 4 respectively;

[0047] On the side of the air compression column 7 facing the driven industrial work disk 4, a ball head column 6 is fixedly connected, and the ball head column 6 is in sliding contact with the inner peripheral surface of the air compression column 7.

[0048] As Figure 2 and Figure 3 shown, the motor fixedly arranged on the base 1 drives the horizontally arranged shaft 2 connected to it to freely rotate in the vertical direction. Then, the integrally formed spline portion 201 on the horizontal shaft 2 drives the driving industrial work disk 3 sleeved thereon to rotate synchronously. Among them, a connecting rod 5 is provided between the driving industrial work disk 3 and the driven industrial work disk 4. When the driven industrial work disk 4 and the driving industrial work disk 3 are parallel, when the driving industrial work disk 3 and the driven industrial work disk 4 rotate synchronously, the air compression column 7 cannot be driven to reciprocate in the horizontal direction through the ball head column 6.

[0049] Among them, when the driving industrial work disk 3 moves in the horizontal direction and drives the driven industrial work disk 4 to deflect on the horizontal shaft 2 through the connecting rod 5, during the process of the driven industrial work disk 4 and the driving industrial work disk 3 rotating synchronously with the horizontal shaft 2, according to the change in the angle between the driven industrial work disk 4 and the horizontal shaft 2, that is, by the change in the inclination of the driven industrial work disk 4, the displacement of the air compression column 7 in the horizontal direction can be changed when the driven industrial work disk 4 rotates one week. Furthermore, the single intake volume during breathing training can be adjusted, and personalized training settings can be made according to the individual differences of trainees.

[0050] On the basis of the embodiment of the horizontal component, the base 1 includes an integrally formed side extension portion 101. The displacement-changing component includes a reciprocating lead screw 15 rotatably fixed on the side extension portion 101. A positioning seat 14 is threadedly connected to the reciprocating lead screw 15, and a horizontal sliding groove 16 for the positioning seat 14 to slide is provided on the side extension portion 101;

[0051] The outer side surface of the abutting seat 14 is in sliding contact with the inner side surface of the driving workbench disc 3.

[0052] As Figures 2 to 4 shown, when the reciprocating lead screw 15 rotates freely in the vertical direction, it can drive the abutting seat 14 threadedly connected to the reciprocating lead screw 15 to slide on the side extension part 101, thereby changing the horizontal position of the abutting seat 14. Among them, the abutting seat 14 is located between the driving workbench discs 3, and the outer peripheral surface of the abutting seat 14 is in sliding contact with the inner peripheral surface of the driving workbench disc 3. Therefore, when the horizontal position of the abutting seat 14 changes, it can drive the driving workbench disc 3 to slide on the spline part 201, thereby changing the distance between the driving workbench disc 3 and the driven workbench disc 4.

[0053] At the same time, when the distance between the driving workbench disc 3 and the driven workbench disc 4 changes, it can drive the driven workbench disc 4 to deflect through the connecting rod 5 arranged between them, thereby changing the angle between the driven workbench disc 4 and the transverse shaft 2. Therefore, when the transverse shaft 2 rotates, it can change the displacement of the air compression column 7 in the horizontal direction through the ball head column 6, thereby changing the intake air volume during breathing training to meet the training needs of different trainees.

[0054] On the basis of the embodiment of the displacement changing assembly, the sound awakening assembly includes a swing rod 21 that swings reciprocally in the vertical direction. The middle part of the swing rod 21 rotates on the base 1 around a fixed axis, and a sector gear 24 is fixedly connected to the end of the swing rod 21. The sector gear 24 is meshed with a tooth column 25, and the tooth column 25 slides through two comb-shaped seats 26;

[0055] Two groups of the comb-shaped seats 26 are fixedly connected with metal sheets 27 that are in contact with the ends thereof corresponding to the horizontal transverse movement positions of the tooth column 25.

[0056] A terminal disc 17 is coaxially fixed on the transverse shaft 2, and a shaft position rod 23 is coaxially fixed on the terminal disc 17. A limiting pin 22 is fixedly connected to the side surface of the shaft position rod 23 facing the swing rod 21, and a slot one for the limiting pin 22 to slide and connect is formed on the swing rod 21.

[0057] As Figures 6 to 8 shown, when the transverse shaft 2 rotates, it can drive the terminal disc 17 and the shaft position rod 23 coaxially fixed thereto to rotate synchronously. Among them, when the shaft position rod 23 rotates forward or reversely in the vertical direction, it can drive the limiting pin 22 fixedly arranged on the shaft position rod 23 to rotate synchronously. At the same time, the limiting pin 22 is slidably connected to the swing rod 21 through the slot one, and the swing rod 21 rotates on the base 1 around a fixed axis. Therefore, when the shaft position rod 23 rotates one week, it can drive the swing rod 21 to reciprocally swing in the vertical direction for one cycle through the limiting pin 22.

[0058] Meanwhile, a sector gear 24 is fixedly arranged on the swing rod 21, and the sector gear 24 is meshed with a tooth column 25. Thus, the reciprocating swing of the swing rod 21 can drive the tooth column 25 to reciprocate in the horizontal longitudinal direction. Two groups of metal sheets 27 are fixedly bonded to the comb-shaped seat 26 corresponding to the position of the tooth column 25 through rubber pads. Thus, when the tooth column 25 moves to one terminal position, that is, when the piston plate 10 is at one end of the horizontal stroke, the impact sound between the tooth column 25 and the metal sheets 27 is used to remind the trainee of the end of the exhalation or inhalation process, so as to help the trainee better master the rhythm of breathing through a clear reminder sound.

[0059] On the basis of the embodiment of the sound component, a coaxial ring 20 coaxial with the end position disk 17 is rotatably fixed on the base 1. A flower-shaped disk 29 is coaxially fixed on one side of the reciprocating lead screw 15 facing the coaxial ring 20. A positioning pin 28 is fixedly connected to one side surface of the coaxial ring 20 facing the flower-shaped disk 29. A plurality of positioning grooves 30 for the positioning pin 28 to slide and connect are formed on the flower-shaped disk 29, and the plurality of positioning grooves 30 are arranged in an annular array.

[0060] An incomplete arc block 32 is fixedly connected to the coaxial ring 20, and a plurality of side shaft arc grooves 31 in sliding contact with the incomplete arc block 32 are formed on the flower-shaped disk 29 corresponding to the positions between two adjacent positioning grooves 30.

[0061] A plurality of relief grooves arranged in an annular array are formed on the end position disk 17. Pawls 18 are arranged in the plurality of relief grooves, and the pawls 18 are rotatably fixed on the end position disk 17. An internal ratchet disk 19 is coaxially fixed on the inner peripheral surface of the coaxial ring 20, and the internal ratchet disk 19 is meshed with the plurality of pawls 18.

[0062] As Figure 2 、 Figure 6 、 Figure 7 and Figure 9 shown, when the transverse shaft 2 drives the end position disk 17 to rotate in the reverse direction, at this time the pawl 18 is not meshed with the internal ratchet disk 19. Thus, at this time, the internal ratchet disk 19 and the coaxial ring 20 do not rotate. Among them, a torsion spring for driving the pawl 18 to return to the initial deflection position is arranged on the end position disk 17. This torsion spring is an existing device and a technical means well known to those skilled in the art, so it is not shown in the figure. Therefore, the intake air volume during subsequent breathing training will not change. When the end position disk 17 rotates in the forward direction, the internal ratchet disk 19 and the coaxial ring 20 can be driven to rotate synchronously through the plurality of pawls 18. Thus, the positioning pin 28 fixedly arranged on the coaxial ring 20 rotates synchronously.

[0063] Meanwhile, a plurality of groups of positioning grooves 30 for the sliding connection of the positioning pins 28 are formed in the flower-shaped plate 29. Thus, when the positioning pins 28 are slidably arranged on a group of positioning grooves 30, the flower-shaped plate 29 and the reciprocating lead screw 15 fixedly coaxial with the flower-shaped plate 29 can be driven to rotate synchronously by a certain angle. Among them, when the reciprocating lead screw 15 rotates, the abutting seat 14 threadedly connected with the reciprocating lead screw 15 can be driven to move in the horizontal direction, so as to change the included angle between the driven work plate 4 and the transverse shaft 2, and further change the intake air volume of the breathing training. After the intake air volume of a single breath is adjusted, the rotation direction of the transverse shaft 2 can be changed to conduct breathing training for the trainee based on this intake air volume after the intake air volume of the breathing training is determined. Moreover, after the positioning pins 28 are disengaged from the positioning grooves 30 at the corresponding positions, the incomplete arc-shaped blocks 32 fixedly arranged on the same-position ring 20 correspond to a group of side shaft arc grooves 31. Thus, the flower-shaped plate 29 is restricted by the incomplete arc-shaped blocks 32 to prevent the flower-shaped plate 29 and the reciprocating lead screw 15 from rotating arbitrarily.

[0064] It should be noted that during actual use, the transverse shaft 2 can be driven to continuously rotate in the reverse direction to drive the end position plate 17, so as to drive the horizontal component and the displacement component to move synchronously, and further continuously and repeatedly adjust the intake air volume of the breathing training. Thus, the change in the breathing requirements in songs with different rhythms can be simulated to help the trainee practice flexibly adjusting the breathing volume between different rhythms, so that the trainee can more flexibly control breathing during actual singing.

[0065] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
