[0002] Art comes from life, and life needs art. With the continuous improvement and development of people's living standards and cultural standards, music has become an indispensable element in people's daily lives. Music can not only help people cultivate their sentiments, but also improve their aesthetic and appreciation abilities, and bring people unique auditory enjoyment. Song singing is accompanied by unique appeal and appeal, and this artistic appeal of singing comes from the singer's singing skills and the expression of the emotions of the song. With the existence of song singing as an artistic form of expression, the problem of singing pitch also arises.

[0003] Although some existing pitch correction devices can achieve the function of pitch correction to a certain extent, they are fixed integrated designs and thus have insufficient adaptability when facing users of different heights.

[0004] In summary, the problem that some existing pitch correction devices are not adaptable enough when facing users of different heights has become a difficult problem that needs to be solved urgently in this field. Therefore, it is necessary to propose a pitch correction device used in music teaching. Summary of the invention

[0005] In order to solve the above problems, the present invention provides a pitch correction device used in music teaching. By adjusting the component, the height of the correction component is adjusted according to the height of the user, so that the pitch correction device can adapt to users of different heights, thereby improving the adaptability of the pitch correction device.

[0008] The first connecting rod is hinged to the second connecting rod at one end away from the gear block, the second connecting rod is hinged to the third connecting rod at one end away from the first connecting rod, the third connecting rod is hinged to the fourth connecting rod at one end away from the second connecting rod, a fixing ring is provided under the threaded disk, the fourth connecting rod is hinged to the inner wall of the fixing ring, and a correction component for correcting the user's pitch is provided under the fixing ring.

[0009] A visual feedback component for providing visual feedback to the user is provided at the bottom of the gear ring.

[0010] The technical principles of the above scheme are as follows:

[0011] The user enters the pitch correction device through the opening and closing door, and adjusts the height of the error correction component through the adjustment component. The controller controls the output shaft of the driving member to rotate, the output shaft of the driving member drives the threaded disk to rotate, the threaded disk drives all the tooth blocks to rotate, the tooth blocks drive the first connecting rod adjacent to it to swing vertically, the first connecting rod drives the second connecting rod, the third connecting rod and the fourth connecting rod adjacent to it to swing vertically in turn, the fourth connecting rod drives the fixing ring to move downward, and the fixing ring drives the error correction component to move downward. At the same time, the controller also drives the visual feedback component to move downward.

[0012] The output shaft of the driving member also drives the gear to rotate during the rotation process, the gear drives the gear ring to rotate, the gear ring drives the telescopic member to rotate, the telescopic member drives the fixed plate to rotate, and the fixed plate drives the display screen to rotate so that it rotates in front of the user.

[0013] The above scheme has the following beneficial effects:

[0014] 1. In the present invention, the adjustment component can adjust the specific height of the error correction component according to the height of the user, so that the error correction component can better receive the audio data generated by the user during the pitch training, and then better exert its error correction ability to achieve accurate correction of the user's pronunciation. At the same time, it also effectively improves the adaptability of the pitch correction device so that it can adapt to users of different heights.

[0015] 2. The visual feedback component of the present invention can provide users with intuitive pitch feedback. Through visual feedback, users can understand their pronunciation status more clearly, so as to practice and improve more targetedly. This audio-visual correction method helps to improve the user's pitch perception ability and correction effect.

[0016] 3. The present invention performs real-time detection and correction on the user's pitch accuracy, so that the user can receive timely guidance, thereby improving the user's pitch training efficiency.

[0017] Furthermore, a plurality of limiting rings are provided below the threaded disk, the fixing ring is located directly below the limiting ring, and the middle portions of the second connecting rod and the third connecting rod are both hinged to the inner side walls of the limiting rings adjacent thereto.

[0018] Beneficial effect: The design of the limit ring provides additional support points for the second link and the third link, which not only enhances the stability of the entire link mechanism, but also effectively reduces the deformation or damage of the second link and the third link caused by uneven force during the adjustment process, thereby extending the service life of the pitch correction device.

[0019] Furthermore, the error correction component includes a correction helmet that is rotatably engaged with the bottom of the fixed ring, and a microphone and earphones are fixedly connected to the correction helmet. The controller is used to collect the user's audio data in real time through the microphone, and send the audio data to the cloud processor. The cloud processor analyzes the user's pitch accuracy and corrects the user's pitch according to the user's pitch accuracy. When the user's pitch is inaccurate, the cloud processor sends a correction signal to the controller, and the controller reminds the user through the earphone that it is about to enter correction training, and plays an audio clip when the user's pitch is inaccurate, to guide the user to sing along.

[0020] Beneficial effects: Through the combination of real-time feedback and personalized correction training, the user's pitch training effect can be significantly improved. Users can identify and correct their pitch problems more quickly, thereby improving training results.

[0021] Furthermore, the visual feedback component includes a fixed plate and a telescopic part symmetrically fixedly connected to the bottom of the gear ring. The controller is used to control the extension and retraction of the telescopic part output shaft. The telescopic part output shaft is fixedly connected to the top of the fixed plate. A display screen is fixedly connected to one side of the fixed plate. The controller is used to display the user's pitch accuracy through the display screen.

[0022] Beneficial effects: The real-time feedback on the display allows users to see whether their pronunciation is correct in time, so that they can quickly adjust their pronunciation. This instant feedback mechanism greatly improves the efficiency of correction, allowing users to achieve better pronunciation results in a shorter time.

[0023] Furthermore, an infrared transmitter is fixedly connected to the top wall of the shell, and the controller is used to receive infrared information sent by the infrared transmitter and send the infrared information to the cloud processor. The cloud processor determines the height of the user and formulates adjustment information according to the height of the user. The adjustment information is sent to the controller, and the controller controls the rotation of the output shaft of the driving member and the extension and retraction of the output shaft of the telescopic member.

[0024] Beneficial effect: By receiving infrared information, the cloud processor can accurately determine the user's height. Based on this information, the pitch correction device can adjust its structure in time to adapt to users of different heights. This personalized adaptation mechanism ensures that each user can get the best experience.

[0025] Furthermore, a pressure sensor is fixedly connected to the bottom wall of the shell, and a platform is fixedly connected to the top of the pressure sensor. The controller is used to receive a pressure signal from the pressure sensor and control the infrared transmitter to emit infrared rays to the user based on the pressure signal.

[0026] Beneficial effects: The intelligent trigger mechanism that detects whether the user is standing on the platform through a pressure sensor can effectively reduce unnecessary energy consumption, saving system resources and storage space while also improving the system's response speed and efficiency.

[0027] Furthermore, a storage cabinet is fixedly connected to the inner bottom wall of the shell.

[0028] Beneficial effect: The design of the placement cabinet provides additional storage space, allowing users to store and retrieve items more conveniently, while optimizing the space layout inside the equipment and improving space utilization.

[0029] Furthermore, the inner side wall of the shell is symmetrically fixedly connected with a handrail.

[0030] Beneficial effect: When a user uses the pitch correction device for a long time, the armrest can provide support for the user's arms and body, reduce the user's fatigue and improve the user's comfort.

[0031] Furthermore, an anti-slip mat is fixedly connected to the top of the platform.

[0032] Beneficial effects: The design of the anti-slip mat effectively increases the friction between the platform and the user's soles, reducing the possibility of users getting injured due to slipping during practice or performance, greatly improving the safety of the pitch correction device, and allowing users to focus on pitch training with greater peace of mind.

[0033] Furthermore, a buffer layer is fixedly connected inside the error correction helmet.

[0034] Beneficial effect: The design of the buffer layer greatly reduces the pressure and discomfort caused by the error correction helmet, which further improves the user experience.

[0035] Additional aspects and advantages of the present invention will be given in part in the following description and in part will be obvious from the following description, or will be learned through practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0041] The following is further described in detail through specific implementation methods:

[0042] Embodiment 1:

[0043] As attached Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown: a pitch correction device used in music teaching, including a shell 1, an opening and closing door 2 is hinged on the side wall of the shell 1, and also includes a controller, the controller is electrically connected to a cloud processor, the top wall of the shell 1 is rotatably matched with a ring gear 3, the inner side wall of the ring gear 3 is meshed with a gear 4, and the top of the gear 4 is rotatably matched with the top wall of the shell 1.

[0044] The bottom of the gear 4 rotates with the limit frame 5, the inner wall of the limit frame 5 is welded with a fixing frame, and the two sides of the fixing frame are symmetrically welded with connecting blocks, which are welded to the inner wall of the housing 1, and the inner wall of the fixing frame is bolted and fixedly connected with a driving member, and the controller is used to control the rotation of the output shaft of the driving member, the output shaft at one end of the driving member is coaxially bolted and fixedly connected with the bottom of the gear 4, and the output shaft at the other end of the driving member is coaxially bolted and fixedly connected with a threaded disk 6, and an adjustment component is provided below the threaded disk 6. In this embodiment, the driving member uses a double-headed motor.

[0045] The adjustment assembly includes a plurality of first connecting rods 7 hinged along the circumference of the lower part of the limit frame 5. The first connecting rods 7 are all integrally formed with tooth blocks 8 at one end close to the limit frame 5. The tooth blocks 8 are all engaged with the bottom of the threaded disk 6 and are all hinged to the limit frame 5.

[0046] The first connecting rod 7 is hinged to the second connecting rod 9 at one end away from the tooth block 8, the second connecting rod 9 is hinged to the third connecting rod 10 at one end away from the first connecting rod 7, the third connecting rod 10 is hinged to the fourth connecting rod 11 at one end away from the second connecting rod 9, a fixing ring 12 is provided below the threaded disk 6, the fourth connecting rod 11 is hinged to the inner wall of the fixing ring 12, a plurality of limiting rings 13 are provided below the threaded disk 6, the fixing ring 12 is located directly below the limiting ring 13, and the middle parts of the second connecting rod 9 and the middle parts of the third connecting rod 10 are hinged to the inner walls of the limiting rings 13 adjacent to them.

[0047] An error correction component for correcting the user's pitch is provided below the fixing ring 12 .

[0048] The error correction component includes a correction helmet 14 that is rotatably engaged with the bottom of the fixed ring 12. A buffer layer is fixedly bonded inside the error correction helmet 14. A microphone and earphones are embedded and installed on the error correction helmet 14. The controller is used to collect the user's audio data in real time through the microphone, and send the audio data to the cloud processor. The cloud processor analyzes the user's pitch accuracy and corrects the user's pitch according to the user's pitch accuracy. When the user's pitch is inaccurate, the cloud processor sends a correction signal to the controller, and the controller reminds the user through the earphone that it is about to enter the correction training, and plays the audio clip when the user's pitch is inaccurate, to guide the user to sing along.

[0049] A visual feedback component for providing visual feedback to the user is provided at the bottom of the gear ring 3.

[0050] The visual feedback assembly includes a fixed plate 15 and a telescopic member symmetrically bolted to the bottom of the gear ring 3, a controller is used to control the extension and retraction of the output shaft of the telescopic member, the output shaft of the telescopic member is bolted to the top of the fixed plate 15, a display screen 16 is bolted to one side of the fixed plate 15, and the controller is used to display the user's pitch accuracy through the display screen 16. In this embodiment, the telescopic member uses an electric telescopic rod.

[0051] An infrared transmitter 17 is fixedly connected to the top wall screw of the outer shell 1. The controller is used to receive infrared information sent by the infrared transmitter 17 and send the infrared information to the cloud processor. The cloud processor determines the user's height and formulates adjustment information according to the user's height. The adjustment information is sent to the controller, and the controller controls the rotation of the double-headed motor output shaft and the extension and retraction of the electric telescopic rod output shaft.

[0052] A pressure sensor 18 is fixedly connected to the bottom wall of the housing 1 by screws, a platform 19 is fixedly connected to the top of the pressure sensor 18 by bolts, and an anti-slip pad is fixedly bonded to the top of the platform 19. The controller is used to receive the pressure signal of the pressure sensor 18 and control the infrared transmitter 17 to emit infrared rays to the user based on the pressure signal.

[0053] The specific implementation process is as follows: the user enters the pitch correction device through the opening and closing door 2 and stands on the platform 19. At this time, the user exerts pressure on the pressure sensor 18 through the platform 19, and the pressure sensor 18 sends a pressure signal to the controller. After receiving the pressure signal, the controller controls the infrared transmitter 17 to transmit infrared rays to the user, and sends the obtained infrared information to the cloud processor, which determines the user's height, formulates adjustment information according to the user's height, and sends the adjustment information to the controller, which controls the double-headed motor output shaft to rotate and the electric telescopic rod output shaft to extend.

[0054] During the rotation process, the output shaft of the double-headed motor will drive the threaded disk 6 to rotate together with it, and the threaded disk 6 will drive all the tooth blocks 8 to rotate together, and the tooth block 8 will drive the first connecting rod 7 adjacent to it to swing vertically, and the first connecting rod 7 will drive the second connecting rod 9, the third connecting rod 10 and the fourth connecting rod 11 adjacent to it to swing vertically in turn, so that the fourth connecting rod 11 drives the fixing ring 12 to move downward, and the fixing ring 12 drives the error correction helmet 14 to move downward so that it can be worn on the user's head.

[0055] At the same time, the output shaft of the electric telescopic rod extends, so that it drives the fixing plate 15 to move downward, and the fixing plate 15 drives the display screen 16 to move downward, so that the display screen 16 is located at the level of the user's head. When the second link 9 and the third link 10 swing, thanks to the additional support points provided by the limit ring 13, the stability of the second link 9 and the third link 10 during the movement is increased, and the deformation and damage caused by uneven force during the vertical swing of the second link 9 and the third link 10 are reduced.

[0056] When the double-headed motor output shaft rotates, it will also drive the gear 4 to rotate, the gear 4 will drive the gear ring 3 to rotate, the gear ring 3 will drive the electric telescopic rod to rotate, the electric telescopic rod will drive the fixed plate 15 to rotate, the fixed plate 15 will drive the display screen 16 to rotate, so that the display screen 16 rotates in front of the user. At this time, the user can complete the adjustment operation by rotating the error correction helmet 14.

[0057] After the display screen 16 and the error correction helmet 14 are adjusted, the user performs pitch training through the microphone. During this process, the microphone collects the user's audio data in real time and sends the user's audio data to the cloud processor, which analyzes the user's audio data and determines the user's pitch accuracy.

[0058] When the cloud processor determines that the user's pitch is inaccurate, the cloud processor sends a correction signal to the controller, and the controller controls the earphone to broadcast a voice message to the user, informing the user that the correction training is about to begin, and plays the audio clip of the inaccurate pitch to the user through the earphone after the broadcast, guiding the user to perform singing-along training with the audio clip. During this process, the display screen 16 will display the changes in the user's pitch accuracy in real time, providing visual feedback to the user.

[0059] In this embodiment, the initial position of the fixing plate 15 is far away from the closing door 2, and the maximum height of the pitch correction device is 2m. After the user enters the pitch correction device, since the position of the display screen 16 will be self-adjusted, it will not block the route of the user entering the pitch correction device during the adjustment process, thereby allowing the user to enter the pitch correction device conveniently.

[0060] The present invention adjusts the height of the correction helmet 14 and the display screen 16 according to the height of the user through the adjustment component, so that the pitch correction device can adapt to users of different heights, thereby improving the adaptability of the pitch correction device.

[0061] Embodiment 2:

[0062] As attached Figure 2 As shown, the difference from Embodiment 1 is that a storage cabinet 20 is fixedly connected to the bottom wall of the housing 1 by bolts.

[0063] The specific implementation process is as follows: When using the pitch correction device, the user can place the items carried with him in the placement cabinet 20 to reduce the influence of external factors on the pitch training.

[0064] Embodiment 3:

[0065] As attached Figure 2 As shown, the difference from Embodiment 2 is that handrails 21 are symmetrically welded to the side walls of the housing 1 .

[0066] The specific implementation process is as follows: when the user uses the pitch correction device for a long time, the armrest 21 can be used as a support point to reduce fatigue caused by training.

[0067] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the invention.
