[0001] The invention relates to the technical field of vocal training equipment, in particular to a vocal breath trainer. Background Art

[0002] Vocal music teaching refers to the educational process of imparting vocal music skills and theoretical knowledge through a series of teaching activities, and cultivating students' music perception, expression ability and stage performance skills. In vocal music teaching, breath training is the basic and key part, which directly affects the quality and expressiveness of singing.

[0003] Vocal breath training refers to a series of exercises to improve the singer's ability to control breath in order to better express musical works. Good breath control is very important for singing, which can help singers maintain the stability and coherence of their voices, as well as the fluency when switching between different ranges.

[0004] Therefore, singers usually often train their breath control. When training their breath, singers often use training devices to achieve better training results. However, existing devices for breath training generally set resistance when the singer blows air to achieve the purpose of training the singer's lung capacity, but it is difficult to train the singer to maintain and control his breath when blowing air.

[0017] Compared with the prior art, the present invention has the following beneficial effects:

[0018] 1. The present invention allows the singer to blow air through the blowpipe with his mouth, allowing the airflow to impact the baffle and tilt the baffle. The singer controls the strength of the blowing and the uniformity of the blowing air volume to keep the baffle at a relatively fixed angle at all times, thereby providing targeted training for the uniformity and stability of the singer's blowing and improving the singer's ability to retain breath. The present application intuitively presents the inclination angle of the baffle to the singer by means of a pointer offset on a dial, so that the singer can evaluate the uniformity and stability of his breath and adjust his breath in time to achieve the training purpose.

[0019] 2. The present invention allows the rocker to drive the sliding rod to slide when the baffle is tilted, and configures a strength rod assembly on the sliding rod that can cause sliding resistance to the sliding rod. Different numbers of strength rod assemblies are inserted to simulate different blowing forces required for different musical symbols. Through the intervention of the strength rod assembly, the singer can train the uniformity and stability of breath in an environment with different breath strengths.

[0020] 3. The strength rod assembly of the present invention has multiple ones, and the resistance to the baffle tilting can be increased or reduced by directly inserting and pulling out, which is more convenient to use. The rotating shaft with a torsion spring can provide the baffle resistance while also providing the driving force required for resetting the baffle.

[0021] 4. A limit pad is sleeved on the bottom of the driven column of the present invention. The size of the limit pad is larger than the size of the sliding rod sleeve and cannot pass through the sliding rod sleeve. When the rotating shaft drives the baffle to reset, the limit pad contacts the top of the sliding rod sleeve and the driven column no longer moves downward. At this time, the movable rod is aligned with the fixed rod, the baffle returns to its initial inclination angle, and the pointer returns to the rightmost end of the dial.

[0022] 5. A closed structure is provided inside the connecting pipe of the present invention, which closes a part of the pipeline of the connecting pipe, and the other part is a second channel. The second channel is aligned with the first channel, and the first channel faces the lower half of the baffle, so that the airflow is concentrated on the lower half of the baffle, which makes it easier for the baffle to tilt and the singer can more easily control the blowing force on the baffle. The end of the closed structure close to the baffle is an arc-shaped surface, and the curvature of the arc-shaped surface matches the curvature of the rotation trajectory of the baffle when it rotates about the shaft. A sealing strip is provided on the baffle, and the sealing strip keeps in contact with the arc-shaped surface, so as to prevent the airflow from leaking from the top of the baffle, which makes it difficult for the baffle to maintain the tilt angle.

Therefore, the features defined as "first" and "second" may explicitly or implicitly include one or more of the features; in the description of the present invention, unless otherwise specified, "plurality" means two or more.

[0036] Example 1

[0037] The uniformity and stability of breath is one of the most important prerequisites for vocal singing. Through the training of breath uniformity and stability, the length and strength of breath can be expanded, and the quality of voice can be improved. Breath uniformity training can also help singers better control their breath, making singing more fluent and natural. In order to be able to train the uniformity and stability of the singer's breath, such as Figure 1 and Figure 2As shown, a vocal breath trainer comprises: an air blowing tube 1, a baffle 3 and a prompting assembly 4, wherein one end of the air blowing tube 1 is used to contact the singer's mouth and abut against the singer's lips, and the other end of the air blowing tube 1 is connected to a connecting tube 2 by a threaded connection, so as to facilitate the replacement of air blowing tubes 1 of different diameters according to the mouth sizes of different singers, such as Figure 2 As shown, a baffle 21 is provided inside the connecting pipe 2, a hole groove is provided in the middle of the baffle 21, and the baffle 21 is inclined; a rotating shaft 32 is provided on one side of the baffle 3 through an auxiliary frame, and the rotating shaft 32 is connected to the inner wall of the connecting pipe 2 and penetrates the pipe wall of the connecting pipe 2. The main body of the baffle 3 is located in the hole groove and matches the hole groove structure. After the baffle 3 is impacted by the airflow, it rotates around the rotating shaft 32 as the axis. In order to reduce the weight of the baffle 3 so that the singer can blow the baffle 3 by blowing, the baffle 3 adopts a plastic thin plate; the prompting component 4 is arranged on the outside of the connecting pipe 2, and is used to prompt the singer when the baffle 3 rotates, the rotation angle of the baffle 3 at this time, and let the singer maintain this angle according to the rotation angle of the baffle 3 at this time, so as to train the uniformity of the singer's breath, such as Figure 1 As shown, the prompt component 4 includes: a dial 41 and a pointer 42. The dial 41 is fixed to the outer wall of the connecting pipe 2, and the center point of the dial 41 coincides with the center axis of the rotating shaft 32; one end of the pointer 42 is connected to the rotating shaft 32, and the pointer 42 rotates at different angles following the rotating shaft 32, so that the other end points to different scale positions of the dial 41. The singer blows the baffle 3 and keeps the pointer 42 at the same scale position, thereby training the uniformity of the air force. Figure 1 and Figure 2 As shown, at this time, the baffle 3 is in a stationary state, and the corresponding pointer 42 indicates the scale line position on the rightmost side of the dial 41, as shown in FIG. Figure 3 As shown, when the baffle 3 rotates, the shaft 32 rotates, and the pointer 42 follows the rotation. The pointer 42 begins to shift to the left side of the dial 41. At this time, the singer needs to keep the pointer 42 on a certain scale line on the left side of the dial 41 to train the uniformity of breathing.

[0038] In such Figure 1 In the illustrated embodiment, since the singer is located at the left end of the connecting tube 2 when blowing, and the surface of the dial 41 is in the same direction as the side of the connecting tube 2, it is inconvenient for the singer to observe the changes of the pointer 42 of the dial 41. In order to facilitate the singer to observe the changes of the pointer 42, a reflector 5 is also included. One side of the reflector 5 is connected to the outer wall of the connecting tube 2 and is located at the position of the dial 41. It is used to provide the status of the prompt component 4 to the singer at one end of the blowing tube 1 by reflection. The angle of the reflector 5 can be adjusted.

[0039] In some embodiments, when the singer sings, different music symbols require different breath strengths to express. For example, different music symbols represent different pitches and intensities, and the singer needs to adjust the breath strength to achieve the requirements of these pitches and intensities. For example, lower notes usually require stronger breath, while higher notes require weaker breath. In addition, the volume is also affected by the breath strength, and more breath strength is usually required to produce a larger volume. During the singing process, the singer needs to flexibly control the breath strength to show the dynamic changes and emotional expression of the music. In order to increase the difficulty of the singer to control the rotation of the baffle 3, that is, to train the singer to maintain the breath under different breath strengths, it also includes: an intensity control component 6, which is used to provide the baffle 3 with a rotation resistance, by arranging a baffle 3 with different rotation resistances to simulate the different breath strengths required for different tones, and when the singer blows the baffle 3 with different blowing strengths, the singer is trained to control the breath stability, so as to achieve the training purpose of the singer's breath uniformity and stability under different breath strengths.

[0040] like Figure 2 and Figure 3 As shown, the strength control assembly 6 includes: a sliding rod sleeve 631, a rocker 61 and a sliding rod 62. The sliding rod sleeve 631 penetrates and is embedded in the wall of the connecting pipe 2; one end of the rocker 61 is connected to the auxiliary frame; the sliding rod 62 slides in the sliding rod sleeve 631, and one end of the sliding rod 62 is rotatably connected to the other end of the rocker 61, as shown in FIG. Figure 3 As shown, when the baffle 3 is tilted, the sliding rod 62 is driven to slide upward through the rocker 61 on the auxiliary frame, and the resistance control component is set at the other end of the sliding rod 62 to control the opening resistance of the baffle 3.

[0041] like Figure 2 and Figure 4 As shown, the resistance control assembly includes: a shell 63, a driven column 64 and a plurality of strength rod assemblies 7. The shell 63 is a box structure and is covered at the position where the sliding rod sleeve 631 is set on the connecting pipe 2. A plurality of fixed tubes 65 are arranged on the inner wall of the shell 63. The size of the fixed tube 65 is slightly larger than the rod size of the strength rod assembly 7. A plurality of through tubes are arranged at the position corresponding to the fixed tube 65 on the other side surface symmetrical to the inner wall of this side. A driven column sleeve 632 is embedded through the top of the shell 63; one end of the driven column 64 is connected to the other end of the sliding rod 62, and the other end slides in the driven column sleeve 632. The driven column 64 is embedded with a plurality of sleeves 641 along its sliding direction; a plurality of strength rod assemblies 7 are inserted from the through tube, passed through the sleeve 641 and then fixed in the fixed tube 65, and the strength rod assembly 7 provides resistance to the sliding of the sliding rod 62, that is, provides resistance to the opening of the baffle 3.

[0042] like Figure 5As shown, the strength rod assembly 7 includes: a movable rod 72, a fixed rod 73 and an insertion rod 7. The movable rod 72 can be made of rubber, such as Figure 4 As shown, when the strength rod assembly 7 is inserted into the housing 63, the movable rod 72 is located in the sleeve 641 of the driven column 64, and when the driven column 64 moves upward, the movable rod 72 is driven to rise; Figure 5 As shown, the fixed rod 73 is symmetrically arranged on both sides of the movable rod 72, and a hole 731 is opened on the side of the fixed rod 73 close to the movable rod 72. A cavity is arranged inside the fixed rod 73, and a wire wheel 75 is arranged in the cavity. The wire wheel 75 is sleeved on the rotating shaft 74, and a torsion spring is arranged on the rotating shaft 74. The torsion spring is used to provide a certain rotation resistance to the rotating shaft 74 and is used for resetting the rotating shaft 74. The two ends of the rotating shaft 74 are rotatably connected to the inner wall of the cavity, and a traction line 751 is wound around the wire wheel 75, and one end of the traction line 751 is fixed on the wire wheel 75. The other end passes through the hole 731 and is connected to one end of the movable rod 72. When the movable rod 72 rises, the traction line 751 is pulled to rotate the wire wheel 75 and the rotating shaft 74. When the blowing force acting on the baffle 3 disappears, the rotating shaft 74 is rotated and reset due to the action of the torsion spring, so that the wire wheel 75 is reversed and the traction line 751 is wound back on the wire wheel 75. At this time, the traction line 751 will pull the movable rod 72, and the movable rod 72 drives the driven column 64 to descend. The driven column 64 resets the baffle through the rocker 61. Figure 4 As shown, a limit pad 642 is sleeved on the bottom of the driven column 64. The limit pad 642 is larger than the sliding rod sleeve 631 and cannot pass through the sliding rod sleeve 631. Figure 2 As shown in the figure, when the limit pad 642 contacts the sliding rod sleeve 631, the driven column 64 no longer moves downward. At this time, the movable rod 72 is aligned with the fixed rod 73, and the baffle 3 returns to Figure 2 one end of the rod 71 is connected to one end of the fixed rod 73 away from the active rod 72, for extending the role, such as Figure 2 As shown, there are multiple strength rod assemblies 7. When not in use, the movable rod 72 is located in the through-tube on the side wall of the shell 63. The length of the through-tube can support the strength rod assembly 7.

[0043] In some embodiments, in order to facilitate the passage of the traction line 751 when the movable rod 72 and the fixed rod 73 are misaligned when the driven column 64 moves, as shown in FIG. Figure 5 As shown, grooves 721 are provided on both sides of the movable rod 72, and connecting members 76 are provided in the grooves 721 for connecting the traction line 751. Figure 6 As shown, slopes 7311 are provided at both ends of the channel 731. The slope 7311 on one side is used to accommodate the connecting piece 76, and the slope 7311 on the other side is used to reduce the friction between the traction line 751 and the channel 731, so that the traction line 751 will not affect the resetting of the movable rod 72 and the alignment with the fixed rod 73.

[0044] In some embodiments, in order to further improve the docking effect between the movable rod 72 and the fixed rod 73, as shown in FIG. Figure 6 As shown, the connecting member 76 includes: a spring 762, a bracket 761 and a roller 763, one end of the spring 762 is connected to the deep part of the groove 721, and the other end is connected to the fixing block; Figure 8 and Fig. 9 As shown, the bracket 761 is set on the fixed block, a round hole is opened on the bracket 761, and one end of the traction line 751 is fixedly connected to the round hole of the bracket 761; the roller 763 is rotatably connected to the bracket 761, and when the movable rod 72 and the fixed rod 73 are misaligned, the spring 762 can undergo a certain deformation so that the roller 763 can be smoothly moved out from the slope 7311 of the channel 731.

[0045] like Figure 6 and Figure 7 As shown, in order to prevent the fixed rod 73 and the movable rod 72 from being misaligned, the traction line 751 is located on the end face of the fixed rod 73, which affects the alignment of the movable rod 72 with the fixed rod 73, a groove 77 is also provided on the side of the fixed rod 73 where the hole 731 is provided. One end of the groove 77 is connected to the top of the hole 731, and the other end extends to the outer wall of the fixed rod 73, so that the traction line 751 enters from the top of the hole 731 and is accommodated in the groove 77, thereby preventing the traction line 751 from being located on the end face of the fixed rod 73 when the fixed rod 73 and the movable rod 72 are misaligned.

[0046] Breath training is an important part of vocal training, which is related to the sound quality, volume and musical expression of singing. Some singers will enhance the power and penetration of singing through some training techniques such as breath retention and breath control during breath training, such as slow inhalation and slow exhalation, slow inhalation and fast exhalation, fast inhalation and slow exhalation, and fast inhalation and fast exhalation. In some embodiments, the device can be used in combination with the above breath training techniques to further improve the singer's ability to retain and control breath, thereby improving the artistic expression of singing. For example, in the slow inhalation and slow exhalation breath training method, the singer takes a deep breath slowly, feels the expansion of the abdomen, keeps the chest relatively stable, and slowly exhales the breath through the outlet pipe into the connecting pipe, while controlling the exhalation speed, and by keeping the inclination angle of the baffle 3 unchanged, the continuity and stability of the exhalation are maintained.

[0047] Example 2

[0048] like Figure 1 and Figure 2As shown, the pipes of the blowing pipe 1 and the connecting pipe 2 of Example 1 are aligned, but the pipe of the blowing pipe 1 is aligned with the entire baffle 3. When the singer blows, the airflow directly acts on the entire baffle 3, and it is difficult to better control the inclination angle of the baffle 3. The difference between Example 2 and Example 1 is that:

[0049] like Fig.10 As shown, the pipe of the blowing pipe 1 is the first channel 11, and a closed structure 23 is provided inside the connecting pipe 2. The closed structure 23 can be an arc-shaped plate structure. The outer arc surface of the closed structure 23 is arranged on the inner wall of the second channel 22, so that a part of the pipe of the connecting pipe 2 is closed, and the other part is the second channel 22. The second channel 22 is aligned with the first channel 11 so that the first channel 11 faces the lower half of the baffle 3, so that the airflow makes it easier for the baffle 3 to tilt. One end of the closed structure 23 close to the baffle 3 is an arc surface 231, and the curvature of the arc surface 231 matches the curvature of the rotation trajectory of the baffle 3 when it rotates with the rotating shaft 32. A sealing strip 31 is sleeved on the baffle 3, and the sealing strip 31 keeps in contact with the arc surface 231, so as to prevent the airflow from leaking from the top of the baffle 3, which makes it difficult for the baffle 3 to maintain the tilt angle.

[0050] The above disclosures are only several preferred specific embodiments of the present invention. However, the embodiments of the present invention are not limited thereto. Any changes that can be conceived by those skilled in the art should fall within the protection scope of the present invention.
