TECHNICAL FIELD

[0001] The present application relates to the technical field of vocal training equipment, in particular to a vocal breath pressure visual training device. BACKGROUND

[0002] In vocal teaching, breath control is the core foundation of singing skills, directly affecting pitch, tone and performance. Traditional breath training mainly relies on the subjective experience of teachers, and assesses whether the use of breath is reasonable through palpation (such as pressing the student's abdomen or throat with fingers). However, this training method lacks quantitative standards, and the teacher's judgment is based on personal experience, making it difficult to provide objective and unified data feedback, resulting in students being unable to accurately master key indicators such as breath strength and stability. Palpation needs to be done one-on-one and relies on repeated adjustments, with a long training cycle, making it difficult to be applied to group teaching on a large scale. Moreover, high-quality vocal teachers are limited in resources, and traditional methods cannot meet the needs of large-scale teaching.

[0003] Currently, although there are some breath training devices on the market, they are mainly for medical rehabilitation or sports fields and cannot directly adapt to the special needs of vocal teaching.

DETAILED DESCRIPTION

[0027] The technical solutions in the embodiments of the application will be described clearly and completely below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0028] Embodiment 1: Please refer to Figures 1-5The utility model provides a vocal breath pressure visual training device, including abdomen pressure change monitoring device and display, abdomen pressure change monitoring device includes waistband 1, the end of waistband 1 is equipped with magic tape 2, the inside of waistband 1 middle part is equipped with the air bag 3 of flat structure, air bag 3 is divided into a plurality of arrayed air cavity units 4 by the partition, the outside of air bag 3 is equipped with a plurality of air pressure sensor 5 corresponding with air cavity unit 4, every air cavity unit 4 is equipped with a vent hole 6 with air pressure sensor 5 communication, the outside of waistband 1 middle part is equipped with abdominal position host 7, and the front end surface of abdominal position host 7 is equipped with touch screen 9 and switch button 8, and abdominal position host 7 is equipped with control chip and wireless signal transmission module in, and air pressure sensor 5 pressure numerical signal is converted into video signal after being transmitted to control chip, and video signal is transmitted to display by wireless signal transmission module.

[0029] The inside of waistband 1 is opposite left and right side abdomen and is equipped with a group of micro vibration motor 11, a group of micro vibration motor 11 vertical equidistance arrangement, control chip one-way transmission control signal to micro vibration motor 11, and the vibration rule of micro vibration motor 11 exists mapping relationship with the value of air pressure sensor 5, and the higher the air pressure stability, the higher the vibration of upper micro vibration motor 11, and the higher the vibration amplitude or vibration frequency of micro vibration motor 11 is higher.

[0030] The inside wall of waistband 1 is opposite left and right side abdomen and is bonded with elastic pad 10, and the thickness of elastic pad 10 is same with the thickness of air bag 3, and the front end of elastic pad 10 is connected with air bag 3 and the two are smoothly transitioned, and the rear end of elastic pad 10 is gradually thinned and is smoothly transitioned with the inside wall of waistband 1.

[0031] The display is a mobile phone, a tablet computer or a notebook computer.

[0032] The both ends of waistband 1 are provided with elastic expansion sections for reducing the discomfort of abdomen during singing training.

[0033] The working principle of the embodiment is as follows:

[0034] When the embodiment is used, the tightness of the waistband 1 is adjusted by the magic tape 2 to fit the abdomen. The elastic expansion sections at both ends of the waistband can reduce the feeling of restraint on the abdomen during singing. The air bag 3 is tightly attached to the abdomen, and the multiple air cavity units 4 on the inner side are evenly distributed to ensure the comprehensiveness of pressure monitoring. The elastic pad 10 is located on the side of the abdomen and the adjacent position, and smoothly connects with the air bag 3 to avoid local compression discomfort. When the user breathes or sings, the contraction and relaxation of the abdominal muscles will change the air pressure in the air cavity units 4, and the air pressure sensor 5 detects the pressure value of each unit in real time through the air hole 6. The air pressure data is transmitted to the control chip in the abdominal host 7 through a wire or wireless transmission, and the chip converts the pressure signal into a digital signal and processes it, such as calculating the average value, stability, etc. The processed data is sent to the display (mobile phone / tablet / computer) through the wireless signal transmission module (such as Bluetooth / Wi-Fi), and the breath pressure distribution, intensity and stability are displayed in the form of a curve graph, heat map, etc. to help users intuitively adjust their breathing patterns. The miniature vibration motor 11 vibrates dynamically according to the air pressure data. The more stable the air pressure, the higher the vibration position (such as higher pitch requires more stable support). The higher the average value of the air pressure, the greater the amplitude or frequency of the motor vibration, prompting the user to adjust the breath support.

[0035] Compared with the traditional vocal breath training method, the embodiment accurately measures the abdominal pressure distribution, intensity and trend of change through the array of air pressure sensors 5 and multiple air cavity units 4, replacing the subjective palpation of the teacher. The display dynamically displays the data, and the user can immediately adjust the breathing strategy. The miniature vibration motor 11 provides tactile feedback to strengthen muscle memory. The embodiment realizes the scientific and standardized vocal breath training through objective data feedback and intelligent interaction, significantly improving the teaching efficiency and learning effect.

[0036] Embodiment 2: Please refer to Figures 6-8 A vocal breath pressure visualization training device, which is different from embodiment 1, further comprises a throat airflow change monitoring device: the throat airflow change monitoring device comprises a neck collar 12 with an arc structure, and each end of the neck collar 12 is provided with a flexible extension arm 14. An ultrasonic probe 15 is installed at the end of each extension arm 14. The rear side of the neck collar 12 is provided with a neck host 13. The neck host 13 is also provided with a control chip and a wireless signal transmission module. The pressure value signal is transmitted to the control chip in the neck host 13 by the ultrasonic probe 15 and is converted into a video signal. The video signal is transmitted to the display by the wireless signal transmission module.

[0037] The two ends of the neck collar 12 are respectively provided with an arm sleeve 16, and the end of the extension arm 14 away from the ultrasonic probe 15 is inserted into the arm sleeve 16. A locking screw is threadedly connected to the outer wall of the arm sleeve 16, the inner end of the locking screw is pressed against the extension arm 14, and the outer end of the locking screw is provided with a screw handle 17.

[0038] The end of the extension arm 14 away from the neck collar 12 is provided with a mounting plate 18, and the mounting plate 18 is provided with a hinged seat 19. The ultrasonic probe 15 is mounted on the hinged seat 19 and can adjust the probe orientation.

[0039] The working principle of the embodiment is as follows:

[0040] When the embodiment works, the user encircles the neck with the neck collar 12 and adjusts the position of the ultrasonic probe 15 through the elastic extension arm 14. The extension arm 14 can be telescopic along the arm sleeve 16 to adapt to different neck sizes, and the locking screw fixes the length of the extension arm 14. The ultrasonic probe 15 adjusts the angle through the hinged seat 19 to ensure that it is opposite to the airflow passage of the throat to accurately capture the airflow changes. The ultrasonic probe 15 emits ultrasonic signals to the throat and receives reflected echoes to detect the airflow speed, flow rate and fluctuation through the Doppler effect, such as the airflow stability when singing. The collected data is transmitted in real time to the control chip in the neck host 13, and the chip converts the original signal into quantized parameters such as flow rate peak value and uniformity. The neck host 13 sends the processed video signal to the display through the wireless signal transmission module, and the video signal is superimposed and displayed with the abdominal pressure data to form an inhalation-airflow collaborative analysis map, such as comparing the matching degree of abdominal support force and throat airflow output.

[0041] The throat monitoring data can be analyzed in conjunction with the abdominal pressure data, for example: when the abdominal air pressure sensor 5 shows insufficient support, if the throat airflow fluctuates violently, the ultrasonic probe 15 detects it and then prompts the user to adjust the breathing and sound coordination. Through the two-way feedback, the scientific nature and systematicness of vocal music training are optimized.

[0042] The embodiment can quantitatively evaluate the coordination of inhalation and sound through real-time monitoring of the throat airflow speed and stability by the ultrasonic probe 15 combined with the abdominal pressure data. The data linkage analysis helps the user to intuitively optimize the breathing and sound coordination, breaks through the limitations of traditional single-site training, and realizes more scientific vocal music training.
