Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of vocal tract training devices, and in particular to a semi-enclosed vocal tract training device. Background Technology
[0002] In voice training, breathing exercises involving partial obstruction of the vocal tract are widely used. They can improve the stability and control of airflow in patients with hoarseness and can also be used as a way for artistic singers to warm up their voices. The scientific validity of this training method has been widely recognized in the voice training community.
[0003] The commonly used training method currently involves using a plastic straw. The straw is held in the mouth and fixed between the upper and lower lips. By observing the airflow exhaled onto the back of the hand, the breathing situation can be understood. Correct breathing is an even exhalation. If the exhaled airflow is uneven or hot, it indicates excessive vocalization. However, the straw training method is inconvenient to use. The straw is too long to fit in a pocket or handbag. In addition, the straw is of a fixed length and cannot be adjusted according to the user's airflow resistance, making it inconvenient for daily use. Utility Model Content
[0004] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a semi-enclosed audio training device that is small in size, easy to carry in daily life, and has adjustable training resistance.
[0005] The technical solution adopted by this utility model is as follows: This utility model includes an air passage block and a slider slidably connected to the air passage block for adjusting the airflow size. An air cavity for airflow is formed inside the air passage block. One end of the air passage block is provided with a mouthpiece communicating with the air cavity. The other end of the air passage block is provided with a sliding groove communicating with the air cavity. A locking block is formed on the bottom surface of the slider and slides with the sliding groove. The bottom surface of the slider is in close contact with the upper surface of the air passage block. Two guide blocks are provided on the upper surface of the air cavity, and each guide block slides with the slider.
[0006] Furthermore, each of the guide blocks has several scale points on its upper part.
[0007] Furthermore, the upper surface of the slider is provided with a push block for finger to push, and a relief groove is formed in the middle of the push block, which corresponds to the guide block for guiding engagement.
[0008] Furthermore, both sides of the push block are provided with protrusions, and each protrusion slides in cooperation with the lower surface of the corresponding guide block.
[0009] Furthermore, the cross-section of the air cavity is set to be circular or elliptical.
[0010] Furthermore, the upper surface of the push block is provided with a marking hole corresponding to the position of the card block.
[0011] Furthermore, the cross-section of the air cavity is set to be rectangular.
[0012] Furthermore, a hanging lug is provided at one end of the airway block near the slide groove.
[0013] The beneficial effects of this utility model are as follows: Because this utility model adopts a guide block and slider structure, the slider slides and presses against the guide block through the protrusion block, so that the lower surface of the slider is close to the upper surface of the air passage block, which is used to press the groove and prevent airflow from flowing out from the gap. The user can adjust the front and back position of the slider by pushing the push block, and determine the degree of sealing of the groove by the slider in conjunction with the scale points and marking points. The user can adjust the airflow resistance level to achieve the best training resistance. The structure is compact and easy to use, and the overall size is small and convenient for daily carrying.

[0021] like Figures 1 to 6As shown, in this embodiment, the present invention includes an airway block 1 and a slider 2 slidably connected to the airway block 1 for adjusting the airflow. An air cavity 11 for airflow is formed inside the airway block 1. One end of the airway block 1 is provided with a mouth part 12 communicating with the air cavity 11. The other end of the airway block 1 is provided with a sliding groove 13 communicating with the air cavity 11. A locking block 25 is formed on the bottom surface of the slider 2, which slides and engages with the sliding groove 13. The bottom surface of the slider 2 is in close contact with the upper surface of the airway block 1. Two guide blocks 14 are provided on the upper surface of the air cavity 11, and each guide block 14 slides and engages with the slider 2. The slider 2 is made of elastic plastic and has good elasticity. The mouthpiece 12 is used for the user to blow air. The airflow passes through the air chamber 11 and flows out from one side of the groove 13. The slider 2 is designed to work with the guide block 14. The slider 2 slides and presses against the guide block 14 through the protrusion 23, so that the lower surface of the slider 2 is pressed against the upper surface of the air passage block 1 to press the groove 13 and prevent the airflow from leaking out from the gap. The user can adjust the position of the slider 2 by pushing the push block 21. With the help of the scale point 15 and the marking point, the user can determine the degree of sealing of the groove 13 by the slider 2. The user can adjust the airflow resistance to achieve the best training resistance. The structure is compact and easy to use. The overall size is small and convenient for daily carrying.
[0022] In this embodiment, each guide block 14 is provided with a plurality of scale points 15 on its upper part. The scale points 15 are designed to make it easy for users to know the air volume of the slide 13, adjust the appropriate airflow resistance, and conduct semi-closed channel training.
[0023] In this embodiment, the upper surface of the slider 2 is provided with a push block 21 for finger pushing. A relief groove 22 is formed in the middle of the push block 21, and the relief groove 22 corresponds to the guide block 14 for guiding engagement. The push block 21 is higher than the highest point of the guide block 14, which makes it convenient for the user to press and push the slider 2 to move back and forth and adjust the air output of the slide groove 13.
[0024] In this embodiment, protrusions 23 are provided on both sides of the push block 21, and each protrusion 23 slides in cooperation with the lower surface of the corresponding guide block 14. The protrusions 23 push and squeeze the lower surface of the guide block 14, so that the lower surface of the locking block 25 is tightly attached to the upper surface of the air passage block 1, preventing the airflow from flowing out of the side wall of the slide groove 13.
[0025] In this embodiment, the upper surface of the push block 21 is provided with a marking hole 24 corresponding to the position of the card block 25.
[0026] In this embodiment, the cross-section of the air cavity 11 is set to be rectangular.
[0027] In this embodiment, the cross-section of the air cavity 11 is set to be circular or elliptical.
[0028] In this embodiment, a hook 16 is provided at one end of the airway block 1 near the slide groove 13. The hook 16 makes it easy for the user to connect and fix the device via a rope, improving the convenience of daily carrying.
[0029] The working principle of this utility model:
[0030] When in use, the user blows air through the mouthpiece 12, and the airflow passes through the air chamber 11 and flows out from one side of the slide 13. The user can adjust the position of the slider 2 by pushing the push block 21, and determine the degree of sealing of the slide 13 by the slider 2 in conjunction with the scale point 15 and the marking point. The user can adjust the airflow resistance level to achieve the best training resistance.
[0031] Although the embodiments of this utility model are described with reference to actual solutions, they do not constitute a limitation on the meaning of this utility model. For those skilled in the art, modifications to the implementation schemes and combinations with other schemes based on this specification are obvious.
