Description

Technical Field

[0001] This invention belongs to the technical field of breath training equipment for vocal and wind instruments, specifically relating to an auxiliary device for breath training and its practice method. Background Technology

[0002] The core foundation of vocal performance and wind instrument playing lies in breath control. The stability of breath, the ability to adjust dynamic gradients, and the smoothness of switching between keys directly determine the pitch, timbre, and expressiveness of the performance. With the development of music training equipment, various breath training devices have emerged, providing practitioners with auxiliary training tools.

[0003] Various breath training devices have emerged in the existing technology. For example, a breath training device for music practice with easy observation, patent number CN113851026B, uses an airflow power generation structure combined with the magnetic repulsion between an electromagnet and a permanent magnet to drive an indicator needle to slide along a scale line, enabling visual observation of the breath training effect and solving the problem that traditional manual training cannot intuitively understand the training effect. However, such devices can only provide feedback on the strength of breath in a single dimension and do not have specialized training functions designed for the key divisions unique to vocal and wind instruments, thus failing to meet the core need of practitioners to switch breath between different keys.

[0004] Further analysis of the shortcomings of existing technologies reveals the following main aspects: (1) Existing devices mostly focus on training and feedback of single breath intensity, without designing a graded training structure based on the breath threshold differences corresponding to the five major keys. This makes it difficult for learners to establish a correspondence between key and breath strength, and thus difficult to support the frequent key switching needs during performance. (2) When switching between different breath intensities (corresponding to different keys), the residual airflow inside the device cannot be quickly expelled, causing interference with the breath pressure of subsequent key training. Learners find it difficult to accurately perceive the breath control standard of the target key, resulting in a large training error. (3) Some devices only provide feedback on breath strength through a single indicator structure, without simultaneously providing feedback on breath stability. Furthermore, the airflow interruption control is mostly triggered by a single button, lacking linkage logic with the breath pressure threshold, which can easily lead to false triggering or control failure, affecting the standardization of training. Summary of the Invention

[0005] To address the aforementioned issues of limited functionality, significant interference during key transitions, and limited feedback dimensions, this invention aims to provide an auxiliary device and practice method for breath training. This device employs a modular layout with a single-channel, multi-key interval, integrating key-level conduction, dual-condition airflow interruption control, rapid residual airflow discharge, and dual-dimensional feedback functions via light and fan blades. Its gradient structure design satisfies the basic training needs for stable breath control in a single key, while the residual air discharge mechanism eliminates airflow interference during key transitions. Furthermore, relying on rigorous control logic and an intuitive feedback mechanism, it helps practitioners establish a correspondence between key and breath strength, enabling a full-cycle, step-by-step training process from basic single-key transitions to advanced key transitions. Ultimately, this improves the practitioner's breath control accuracy and the smoothness of key transitions, making it suitable for specialized training needs in vocal performance and wind instrument playing.

[0006] To achieve the above objectives, the technical solution adopted by the present invention is as follows: An auxiliary device for breathing training includes a main pipe body arranged in a single-channel structure, and further includes: Several key-tone intervals are independently set up within the main pipe, and each key-tone interval is connected to the air inlet of the main pipe. The palace-tone zoning mechanism is set at the air outlet of each of the palace-tone zones and is used to control the unidirectional flow and interruption of airflow in the corresponding palace-tone zone. The breath feedback mechanism is installed on the main tube corresponding to each of the aforementioned tonal intervals.

[0007] Furthermore, the palace tone interval body includes: The breath regulating block slides in conjunction with the interior of the main tube body and has a first communication port that communicates with the interior of the main tube body. Several sliders are arranged circumferentially along the outer wall of the breath regulating block and slide in cooperation with the slide rails inside the main pipe.

[0008] Furthermore, the auxiliary device also includes: The guide rod is connected to the slider along the axial direction of the slide rail; An elastic element is sleeved on the outer periphery of the guide rod, and its two ends abut against the main tube body and the slider, respectively; A trigger block is mounted on the slider and is adapted to a slot within the slide rail.

[0009] Furthermore, the palace tone zoning mechanism includes: A one-way valve is provided on the second connection port that connects the air regulating block to the inside of the main pipe. A magnetic valve is installed in the third communication port opened on the side wall of the air regulating block, and is equipped with a corresponding magnetic valve control button.

[0010] Furthermore, the breath feedback mechanism includes: A pressure sensor is mounted on the side wall of the main pipe and is slidably connected to the guide rod. A pressure-sensing lamp is fitted around the outer periphery of the pressure sensor and is electrically connected to the pressure sensor.

[0011] Furthermore, the breath feedback mechanism also includes: The mounting groove is provided on the outer wall of the main pipe body and communicates with the third communication port; The turbine blades are disposed in the mounting slot and mounted on the third communication port via a rotating bearing.

[0012] Furthermore, the auxiliary device also includes an airflow switching mechanism, which is connected to each of the palace / tone intervals and is used to control the residual airflow discharge during the switching of each palace / tone interval; the airflow switching mechanism includes: Several single-tuning suction tubes are connected to the cavities between adjacent tuning sections; The four-blade sliding controller is electrically connected to the airflow discharge control valve installed on the single-cell regulating air extraction pipe; An exhaust pump is located at the bottom of the main pipe and is connected to the single-stage regulating exhaust pipe. It is used to control the residual airflow to be discharged through the single-stage regulating exhaust pipe.

[0013] Furthermore, the auxiliary device also includes: A power generation and energy supply mechanism is located near the air inlet and is used to start the power generation and energy supply mechanism with airflow to achieve self-powering. A side handle is installed on the outer wall of the main pipe and is equipped with control buttons for controlling the zoning mechanism and the power generation mechanism.

[0014] On the other hand, a method for practicing with an auxiliary device for breath training, using the aforementioned auxiliary device for breath training, includes single-tone progressive training, tone forward switching training, and tone reverse switching training.

[0015] Furthermore, the specific steps of the single-tone progressive training are as follows: S1: Move the four-blade sliding controller to the limit position and close the airflow discharge control valves of all palace-tone sections; S2: Press the magnetic valve control button corresponding to the target tuning interval to be trained; S3: The practitioner exhales into the mouth, judges the strength of the breath by the status of the pressure sensor light, adjusts the exhalation force to keep the pressure sensor light of the target tone range constantly lit, and judges the stability of the breath by the rotation stability of the turbine blades, until the stable control of the breath in the target tone is achieved. The specific steps of the positive switching training of the palace tone are as follows: Based on the single-tone progressive training, directly press the magnetic valve control button of the next tone interval and close the magnetic valve of the current tone. The practitioner increases the blowing force to keep the pressure sensor light of the next tone interval on, thus completing the positive switch from low breath value tone to high breath value tone. The specific steps of the palace tone reverse switching training are as follows: Press the magnetic valve control button of the target palace tone interval and close the magnetic valve of the current palace tone. Move the four-blade sliding controller to the target palace tone position and open the airflow discharge control valve of the palace tone interval above the target palace tone to discharge the residual airflow.

[0016] The beneficial effects of this invention are: 1. In this invention, the inter-tone intervals are indirectly connected to the cavity of the main tube through the first connecting port of the breath regulating block, and adjacent inter-tone intervals are connected in stages through a connecting one-way valve. By combining the design of the breath regulating block, the connecting one-way valve and the elastic element, a step-by-step training logic is constructed in which weak breath triggers low tone and strong breath triggers high tone.

[0017] 2. In this invention, the trigger block is fixedly connected to the slider and adapted to the slide groove. Only when the practitioner's blowing force reaches the breath threshold of the target tone, pushing the breath adjustment block to slide and causing the trigger block to engage in the groove, will the magnetic valve be energized and opened based on the triggering of the magnetic valve control button. This linkage structure ensures that the opening of the magnetic valve matches the practitioner's breath ability, avoiding training logic confusion caused by accidental button presses, and ensuring that each tone training session is based on the target breath intensity, significantly improving the standardization and accuracy of training.

[0018] 3. In this invention, during the reverse switching of the musical mode (from high to low), the exhaust pump starts simultaneously, quickly extracting residual airflow from the high-mode area through a single-mode exhaust pipe, thus rapidly restoring the pressure environment of the target mode to stability. This structure effectively solves the switching interference problem caused by residual airflow in existing devices, allowing practitioners to quickly perceive the breath control standard of the target mode, shortening the switching adaptation time, and improving the smoothness and stability of mode switching.

[0019] 4. This invention uses a sliding connection between a pressure sensor and a guide rod to convert airflow pressure into a signal for the on / off state of a pressure-sensitive light. Each tone interval corresponds to an independent pressure-sensitive light, employing a gradient lighting mode. Practitioners can intuitively judge whether their breath has reached the target tone threshold through the light's status, solving the problem of not being able to see or accurately gauge breath intensity. The turbine blades are mounted at the third connection port of each tone interval via a rotating bearing. When airflow is expelled, it drives the blades to rotate. The smoothness of this rotation is positively correlated with the smoothness of breath—uniform rotation indicates stable breath, fluctuating speed indicates breath fluctuation, and complete stoppage indicates breath interruption. This structure supplements the breath smoothness dimension that the pressure-sensitive light cannot provide feedback on, forming a dual feedback mechanism where the light indicates intensity and the blades indicate smoothness. This helps practitioners fully perceive their own breath state and adjust their blowing force and rhythm accordingly. Attached Figure Description

[0022] To enable those skilled in the art to better understand the technical solutions of the present invention, the technical solutions of the present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0023] See attached document Figure 1-15 The auxiliary device for breath training in this application includes a main pipe body 1, and a tone interval body 2, a tone zoning mechanism 3, and a breath feedback mechanism 4 integrated on the main pipe body 1. The main pipe body 1 is a hollow cylindrical single-pipe structure with an open breath inlet 101 at one end for the practitioner to blow air in. Several slides 102 are provided axially on the inner wall of the main pipe body 1 to guide the sliding cooperation of the tone interval body 2. Side handles 10 are fixed to both sides of the main pipe body 1 as gripping parts for the practitioner. Various control buttons and controllers are integrated on the side handles 10 to achieve convenient one-handed operation.

[0024] Several key intervals 2 are independently arranged within the main pipe 1, running axially from the air inlet 101 to the other end. In this embodiment, there are five key intervals 2, each corresponding to one of the five major keys of vocal / wind instruments. Each key interval 2 is indirectly connected through a common internal cavity of the main pipe 1, and adjacent key intervals 2 are connected in stages via a key zoning mechanism 3. The key zoning mechanism 3 is configured one-to-one with each key interval 2, located at the air outlet of each key interval 2, enabling unidirectional airflow control of each key interval 2. A breath feedback mechanism 4 is correspondingly located on the main pipe 1 with each key interval 2, used to provide feedback on the strength and stability of the breath exhaled by the practitioner.

[0025] The main pipe body 1 is also equipped with a guide rod 7, an elastic element 8, and a trigger block 9. The guide rod 7 is slidably connected to the palace adjustment interval body 2 along the axial direction of the slide rail 102. The elastic element 8 is sleeved on the outer periphery of the guide rod 7, with its two ends abutting against the main pipe body 1 and the palace adjustment interval body 2, respectively. The trigger block 9 is set on the palace adjustment interval body 2 and is adapted to the slot in the slide rail 102. The three components work together to realize the sliding guidance, reset, and positioning of the palace adjustment interval body 2. A power generation and power supply mechanism 5 is provided on the side of the main pipe body 1 near the air inlet 101. It is self-powered by airflow drive and supplies power to all electrical components of the device. The main pipe body 1 is also equipped with an airflow switching mechanism 6, which is connected to each palace adjustment interval body 2. It is used to quickly discharge residual airflow during palace adjustment switching, eliminate airflow interference between palace adjustments, and reduce training errors.

[0026] The moderation section 2 includes a breath regulating block 201 and several sliders 202. The breath regulating block 201 is a hollow block structure that slides within the main pipe 1. It has a first connecting port 2011 and a second connecting port 2012 sequentially along its axial direction, and a third connecting port 2013 radially along its side wall. The first connecting port 2011 directly communicates with the internal cavity of the main pipe 1, serving as the main channel for airflow into the breath regulating block 201. The second connecting port 2012 is used to install the moderation zoning mechanism 3, enabling unidirectional airflow. The third connecting port 2013 is the core channel for airflow exit from the breath regulating block 201, incorporating a magnetic valve and connecting to an external breath feedback mechanism 4 to achieve airflow interruption control and breath stability feedback.

[0027] Several sliders 202 are fixedly connected at intervals along the outer circumference of the breath regulating block 201. The number of sliders 202 is the same as the number of slides 102 on the inner wall of the main tube 1, and the sliders 202 slide in conjunction with the slides 102 to achieve smooth sliding of the breath regulating block 201 along the axial direction of the main tube 1. A guide rod 7 is arranged along the axial direction of the slide 102, and its axis is parallel to the axis of the breath regulating block 201. One end of the guide rod 7 is fixed to one side of the slider 202, and the other end faces the tail of the main tube 1, providing secondary guidance for the sliding of the slider 202 and ensuring sliding stability. The elastic element 8 is a compression spring, sleeved on the outer circumference of the guide rod 7, with its two ends abutting against the inner wall of the main tube 1 and the slider 202, respectively. When the airflow pushes the breath regulating block 201 to slide, the elastic element 8 is compressed to generate elastic restoring force, realizing the automatic reset of the breath regulating block 201 after the practitioner stops blowing. The trigger block 9 is fixed to the side wall of the slider 202 and matches the slot opened in the inner wall of the slide rail 102. When the breath adjustment block 201 slides to the preset mode position, the trigger block 9 is engaged in the slot. On the one hand, this fixes the position of the mode interval body 2, preventing displacement due to airflow impact during training and ensuring training accuracy. On the other hand, the engagement of the trigger block 9 in the slot will simultaneously trigger the opening signal of the mode partitioning mechanism 3.

[0028] The Gongdiao (palace tone) zoning mechanism 3 includes a connecting one-way valve 301, a magnetic valve, and a magnetic valve control button 302. The connecting one-way valve 301 is installed at the second connecting port 2012 of the breath regulating block 201. Its conduction direction is one-way from the main pipe 1 to the breath regulating block 201, and then one-way from the breath regulating block 201 to the next section of the main pipe 1. It only allows the blowing airflow to flow out of the Gongdiao zone 2, effectively preventing the airflow in the main pipe 1 from flowing back to the Gongdiao zone 2, avoiding cross-interference of airflow between the Gongdiao zones 2, and ensuring the independence of single Gongdiao training.

[0029] The magnetic valve is embedded in the third connection port 2013 of the breath control block 201, serving as the main control valve for the airflow discharge of each tuning interval 2. Each tuning interval 2 corresponds to an independent magnetic valve. The magnetic valve's on / off state requires two conditions to be met simultaneously: first, the corresponding magnetic valve control button 302 must be pressed; second, the trigger block 9 must engage with the slot in the slide rail 102 and generate a trigger signal. The magnetic valve control button 302 is embedded in the side handle 10. Pressing the button 302 energizes the magnetic valve, generating magnetic force to open it; pressing it again de-energizes and closes it. This allows for independent control of the airflow in a single tuning interval 2, meeting the needs of targeted training for a single tuning interval, and providing basic flow control conditions for tuning switching training.

[0030] The breath feedback mechanism 4 includes a pressure sensing component and a rotation feedback component. The pressure sensing component includes a pressure sensor 401 and a pressure sensing lamp 402. The pressure sensor 401 is embedded in the side wall of the main tube 1, and its sensing end extends into the main tube 1 and is slidably connected to the end of the guide rod 7 away from the slider 202. When the airflow pushes the breath regulating block 201 to slide, the guide rod 7 moves synchronously with the slider 202 and abuts against the sensing end of the pressure sensor 401. The pressure sensor 401 detects the airflow pressure value according to the magnitude of the abutment force. The pressure sensor 402 is sleeved on the outer periphery of the pressure sensor 401 and electrically connected to the pressure sensor 401. Each tone interval 2 corresponds to an independent pressure sensor 402. The pressure sensor 402 adopts a gradient lighting mode: when the airflow pressure value reaches the breath threshold of the corresponding tone, the pressure sensor 402 of that tone is constantly lit; when the airflow pressure value is insufficient, the light is off; when the pressure is too high, the pressure sensor 402 of the next tone lights up simultaneously. The practitioner can intuitively judge the strength of their own breath by the on / off state of the pressure sensor 402 and adjust the blowing force in time.

[0031] The rotational feedback assembly includes a mounting slot 403, a cover plate 4031, and a turbine blade 404. The mounting slot 403 is formed on the outer wall of the main pipe body 1 and coaxially communicates with the third connecting port 2013 of the air conditioning block 201, providing mounting space for the turbine blade 404. The cover plate 4031 is detachably fitted onto the open end of the mounting slot 403, providing protection for the turbine blade 404 and facilitating subsequent cleaning and maintenance. The turbine blade 404 is mounted on the end of the third connecting port 2013 via a rotating bearing and is located within the mounting slot 403. When the airflow within the Gongdiao interval 2 is discharged through the third connecting port 2013, the airflow drives the turbine blade 404 to rotate. The rotational stability of the turbine blade 404 is positively correlated with the stability of the practitioner's breath: when the breath is stable, the turbine blade 404 rotates at a uniform speed; when the breath fluctuates, the rotational speed of the turbine blade 404 fluctuates; when the breath is interrupted, the turbine blade 404 stops rotating. The practitioner can intuitively judge the stability of their own breath through the rotational state of the turbine blade 404, thus achieving breath control training.

[0032] The airflow switching mechanism 6 includes several single-mode air extraction pipes 601, a four-blade sliding controller 602, an exhaust pump 603, and several airflow discharge control valves 604. The inlet ends of the single-mode air extraction pipes 601 are connected to the cavities between adjacent mode sections 2, and the outlet ends converge at the bottom of the main pipe 1 and are connected to the exhaust pump 603. Each single-mode air extraction pipe 601 is equipped with a corresponding airflow discharge control valve 604 for independent control of the opening and closing of the single-mode air extraction pipe 601. The four-blade sliding controller 602 is embedded in the side handle 10 and electrically connected to each airflow discharge control valve 604. Specifically, it uses a KCD4-4P four-blade four-throw sliding switch, which is a multi-position controller. The four-blade sliding controller 602 has limit positions and adjustment positions corresponding one-to-one with the five mode sections 2. By sliding the four-blade sliding controller 602, the simultaneous opening / closing of multiple airflow discharge control valves 604 can be achieved, adapting to the switching needs of different modes. The exhaust pump 603 is embedded in the covering pad 11 on the outer wall of the main pipe 1 to provide power for the discharge of residual airflow. When the airflow discharge control valve 604 is opened, the exhaust pump 603 works synchronously to quickly extract the residual airflow in the palace adjustment interval 2 through the single palace adjustment air extraction pipe 601 and discharge it outside the device, thereby eliminating the pressure interference of residual airflow on subsequent palace adjustment training and reducing training errors.

[0033] The power generation mechanism 5 is located inside the main pipe body 1 and near the air inlet 101. It includes a permanent magnet 501, a fan blade 502, a coil 503, and a wire 504. Two permanent magnets 501 are fixed to the side wall of the main pipe body 1, forming a stable magnetic field environment. The fan blade 502 is rotatably mounted inside the main pipe body 1 via a shaft, directly facing the air inlet 101. The airflow from the practitioner directly drives the fan blade 502 to rotate at high speed. The coil 503 is wound around the shaft of the fan blade 502. As the fan blade 502 rotates, it cuts magnetic field lines within the magnetic field of the permanent magnet 501, generating an induced electromotive force to achieve self-generation. The coil 503 is electrically connected to all electrical components of the device (pressure sensor 401, pressure sensor lamp 402, magnetic valve, magnetic valve control button 302, four-blade sliding controller 602, and exhaust pump 603) via wire 504, so as to stably deliver the generated electrical energy to each electrical component, realize the device's full self-powering, and ensure the normal operation of each functional module.

[0034] Example 2 This application also discloses a breath training method using the aforementioned auxiliary device for breath training, including progressive single-key training, forward key switching training, and reverse key switching training. These three steps proceed gradually, first enabling the learner to achieve stable breath control in a single key, and then achieving smooth forward / reverse key switching. This aligns with the breath training principles for vocal / wind instruments, effectively improving the learner's breath control ability and the fluency of key switching. The specific operation of each step is as follows: The single-tone progressive training is the basic training step, aiming to achieve precise control of the practitioner's breath strength and stability in a single tone. During training, first, the four-blade sliding controller 602 is switched to the limit position, closing the airflow discharge control valves 604 corresponding to all tone intervals 2 to prevent airflow leakage from the single-tone suction pipe 601, ensuring all airflow enters the target tone interval 2. Then, according to training needs, the magnetic valve control button 302 corresponding to the target tone interval 2 is pressed. At this time, the magnetic valve is not yet open; the practitioner needs to blow air to push the breath adjustment block 201 to slide, causing the trigger block 9 to engage with the slot in the slide rail 102. The practitioner slowly blows air into the main pipe 1 through the breath inlet 101. The airflow enters the breath adjustment block 201 of the target tone through the first connecting port 2011, simultaneously pushing the breath adjustment block 201 to slide along the slide rail 102. The guide rod 7 moves with the slider 202 and abuts against the pressure sensor 401, triggering the pressure sensor light 402. The practitioner judges their breath strength by observing the illumination status of the pressure sensor 402, and slowly adjusts the blowing force to keep the pressure sensor 402 corresponding to the target tone interval 2 constantly lit. Simultaneously, the practitioner observes the rotation of the turbine blades 404 and adjusts the smoothness of the blowing until the turbine blades 404 rotate at a constant speed and the pressure sensor 402 remains constantly lit. At this point, the trigger block 9 engages in the slot of the slide 102, fixing the position of tone interval 2. The practitioner has completed the breath control training for that tone. Repeating the above steps, the practitioner completes the progressive training of each of the five tones, laying a solid foundation for breath control in subsequent tone switching training.

[0035] The forward switching training of the musical mode is an advanced training step, aiming to enable the practitioner to smoothly switch the breath from a low-breath value musical mode to a high-breath value musical mode (the low-breath value musical mode is the one closest to the breath inlet 101, and the high-breath value musical mode is the one furthest from the breath inlet 101). Based on the progressive training of the single musical mode, the practitioner maintains a stable breath state in the current musical mode (pressure sensor light 402 is constantly lit, turbine fan blade 404 rotates at a constant speed). Directly press the magnetic valve control button 302 corresponding to the next musical mode interval 2 to open the magnetic valve of the next musical mode—since each musical mode is equipped with an independent breath adjustment block 201, slider 202 and guide rod 7, after the magnetic valve corresponding to the current musical mode is closed, the airflow in its breath adjustment block 201 no longer flows outward, but flows into the main pipe section 1 corresponding to the next musical mode through the connecting one-way valve 301. At this point, the airflow pressure within the current mode's breath control block 201 is insufficient to maintain the trigger block 9 in its slot. Under the action of the reset force, the elastic element 8 pushes the slider 202 to slide in the opposite direction, causing the trigger block 9 of the current mode to disengage from its slot in the slide rail 102 and reset. The practitioner slowly increases the blowing force, and the airflow enters the first connecting port 2011 of the next mode through the common cavity of the main tube 1, pushing the breath control block 201 of that mode to slide along the slide rail 102 until its trigger block 9 is engaged in the corresponding slot. At this time, the magnetic valve of the next mode simultaneously meets the dual conditions of pressing the corresponding magnetic valve control button 302 and the trigger block 9 being engaged in its slot, opening with power. The airflow is discharged through the third connecting port 2013 and drives the turbine blade 404 to rotate. When the pressure sensor light 402 corresponding to the next mode's interval 2 remains constantly lit, and the turbine blade 404 maintains a uniform rotation speed, the forward switching from a low-breath-value mode to a high-breath-value mode is completed. Repeat the above steps to complete the forward continuous switching training from the first key to the fifth key, gradually improving the practitioner's ability to control breath amplification and achieve a smooth switching from low to high keys.

[0036] The reverse switching training of the palace tone is an advanced training step. Its goal is to enable the practitioner to smoothly switch their breath from a high-breath-value palace tone to a low-breath-value palace tone. The core is to quickly expel residual airflow from the high-breath-value palace tone through the airflow switching mechanism 6, eliminating airflow pressure interference. Building upon the single-palace tone progressive training or the palace tone forward switching training, the practitioner maintains a stable breath state in the current high-breath-value palace tone. Press the magnetic valve control button 302 corresponding to the target low-breath-value palace tone interval 2 to open the magnetic valve of the target palace tone, while simultaneously closing the magnetic valve of the current high-breath-value palace tone. Immediately move the four-blade sliding controller 602 to the adjustment position corresponding to the target palace tone, opening the airflow discharge control valves 604 corresponding to all high-breath-value palace tone intervals 2 above the target palace tone. The exhaust pump 603 starts simultaneously, quickly extracting and expelling residual airflow from all palace tone intervals 2 above the target palace tone through the single-palace tone extraction pipe 601. The practitioner observes the off state of the pressure sensor light 402 corresponding to the key above the target key. When this part of the pressure sensor light 402 is completely off, it is determined that all residual airflow has been expelled. At this time, the practitioner immediately and slowly reduces the blowing force. The elastic element 8 of the high breath value key range body 2 returns to its original deformation, pushing the breath adjustment block 201 to slide towards the low breath value key, until the trigger block 9 of the target key range body 2 is engaged in the corresponding slot. The magnetic valve of the target key receives the trigger signal and is energized and opened. The airflow pressure value is precisely matched with the breath threshold of the target low breath value key. The pressure sensor light 402 corresponding to the target key remains constantly lit, and the turbine fan blade 404 maintains a uniform rotation speed, completing the reverse switch from the high breath value key to the low breath value key. Repeat the above steps to complete the reverse continuous switching training from the fifth key to the first key, gradually improving the practitioner's breath reduction control ability and the smoothness of key switching, meeting the needs of flexible key switching in vocal / wind instrument performance.
