Description

Technical Field

[0001] The invention relates to the technical field of voice training, and in particular to a voice training device based on magnetic fluid. Background Art

[0002] The magnetofluid voice trainer cleverly combines the physical properties of magnetofluid with sound control technology. Its working principle is based on the dynamic changes of magnetofluid under the action of magnetic field. When the sound signal is converted into electrical signal through the device, and then drives the magnetic field to change, the magnetofluid will dance accordingly, presenting a dynamic visual effect that matches the rhythm and strength of the sound. This innovative design not only makes the voice training process intuitive and perceptible, but also greatly enhances the user's sense of participation and interactivity. Users can perceive their own voice state by observing the changes in the magnetofluid, and thus adjust their voice skills more accurately.

[0003] After searching, the invention patent with Chinese patent number CN114449388A discloses a magnetic fluid speaker and a control circuit. Compared with the prior art, the invention patent with Chinese patent number CN114449388A solves the problem of controlling ferromagnetic fluid by changing the magnetic force of an electromagnet in the prior art, but the electromagnet is controlled by current and voltage, which leads to high cost.

[0004] However, in actual use of the above device, the two motors control the movement of the two electromagnets respectively, which may cause interference in the control of the magnetic fluid by the two electromagnets at the same time, and fail to achieve the expected display effect. In addition, when the surrounding electromagnetic field is strong, it may affect the operation of the magnetic fluid, and the ability to resist interference from the external environment is weak. Therefore, a voice trainer based on magnetic fluid is proposed. Summary of the invention

[0005] The purpose of the present invention is to solve the shortcomings of the prior art that two electromagnets form interference and have low anti-interference ability, and to propose a voice training device based on magnetic fluid.

[0006] In order to achieve the above object, the present invention adopts the following technical solutions:

[0007] A voice training device based on magnetic fluid, comprising a support frame and a magnetic fluid transparent box. A protective plate is fixedly connected to the inner side of the support frame. A base is fixedly connected to the bottom of the support frame. A plurality of fixed blocks are fixedly connected to the inner side of the support frame, and the plurality of fixed blocks are fixedly connected to the magnetic fluid transparent box together. Two groups of speakers are symmetrically and fixedly connected to both sides of the support frame, and the number of the speakers is multiple. A radio is fixedly connected to the side surface of the support frame. A moving component is arranged at the inner bottom of the support frame. The moving component includes a first sliding plate, a first lead screw, a second sliding plate and a second lead screw. A first electromagnet is fixedly connected to the side of the second sliding plate close to the magnetic fluid transparent box. A protection component is arranged inside the support frame. The protection component includes a third motor and symmetrically arranged first protective sleeves

[0008] The above technical solution further includes:

[0009] A motor fixing block is fixedly connected to the inner bottom of the support frame. A first motor is fixedly connected to the side of the motor fixing block close to the first sliding plate. The output end of the first motor is fixedly connected to the first lead screw

[0010] The first sliding plate is in threaded connection with the first lead screw. A second sliding support frame and a first sliding support frame are respectively fixedly connected to the inner bottom of the support frame. The second sliding support frame and the first sliding support frame are slidably connected to the first sliding plate together

[0011] A first chute is opened on the side of the first sliding plate close to the magnetic fluid transparent box. The first chute is slidably connected to the second sliding plate. A second chute is opened on the side of the first sliding support frame close to the second lead screw. A sliding fixing block is slidably arranged inside the second chute

[0012] The sliding fixing block is fixedly connected to the side of the second lead screw close to the second lead screw. The output end of the second motor is fixedly connected to the second lead screw. The second lead screw is in threaded connection with the second sliding plate. By arranging the moving component, the first electromagnet can be moved arbitrarily on the horizontal X / Y coordinates, improving the control effect of the first electromagnet on the magnetic fluid and reducing the interference effect. In addition, by controlling the magnetic field strength of the first electromagnet, precise control of the magnetic fluid can be achieved

[0013] Both of the two first protective sleeves are fixedly connected to the support frame. Second protective sleeves are slidably arranged inside the two first protective sleeves. Third protective sleeves are slidably arranged inside the two second protective sleeves. By arranging the protection component, when the external electromagnetic interference is strong, the magnetic fluid transparent box can be protected by the movement of the third protective sleeve, reducing the interference of the external electromagnetic field, making the voice training more stable and improving the training effect

[0014] On one side of the two third protective sleeves close to the magnetorheological fluid transparent box, electromagnetic blocks are symmetrically and fixedly connected. The two third protective sleeves are commonly threadedly connected to a bidirectional threaded rod, and a gear is fixedly connected to the central position of the bidirectional threaded rod.

[0015] A third motor is fixedly connected to one side of the support frame close to the gear, and a worm is fixedly connected to the output end of the third motor. The gear meshes with the worm.

[0016] Shielding plates are symmetrically and slidably arranged inside the magnetorheological fluid transparent box. Second electromagnets are symmetrically and fixedly connected to both ends of the shielding plates. The second electromagnets and the electromagnetic blocks are in the same horizontal and vertical positions.

[0017] Both the two second protective sleeves and the two third protective sleeves are slidably connected to the fixed square block. The opening sizes of the two third protective sleeves are adapted to the height size of the magnetorheological fluid transparent box. By arranging the second electromagnets and the shielding plates, when the device is not in use, through the arranged electromagnetic blocks, under the action of the third motor, the two third protective sleeves approach each other to protect the magnetorheological fluid transparent box. Subsequently, the arranged shielding plates aggregate the magnetorheological fluid, reducing the disturbance of the external environment to the magnetorheological fluid and improving the service life.

[0018] The present invention has the following beneficial effects:

[0019] 1. In the present invention, through the arranged moving component, the first electromagnet can be moved arbitrarily on the horizontal X / Y coordinates, improving the control effect of the first electromagnet on the magnetorheological fluid and reducing the interference effect. Additionally, by controlling the magnetic field magnitude of the first electromagnet, precise control of the magnetorheological fluid can be achieved.

Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0035] Embodiment 1

[0036] As Figures 1 - 11 shown, a voice training device based on magnetic fluid proposed by the present invention includes a support frame 2 and a magnetic fluid transparent box 5. A protective plate 8 is fixedly connected to the inner side of the support frame 2. A base 1 is fixedly connected to the bottom of the support frame 2. A plurality of fixed blocks 6 are fixedly connected to the inner side of the support frame 2. The plurality of fixed blocks 6 are fixedly connected to the magnetic fluid transparent box 5 together. Two groups of speakers 4 are symmetrically and fixedly connected to both sides of the support frame 2, and the number of the speakers 4 is multiple. A radio receiver 3 is fixedly connected to the side surface of the support frame 2. A moving component is arranged at the inner bottom of the support frame 2. The moving component includes a first slide plate 15, a first lead screw 16, a second slide plate 24 and a second lead screw 27. A first electromagnet 23 is fixedly connected to the side of the second slide plate 24 close to the magnetic fluid transparent box 5. A protection component is arranged at the inner side of the support frame 2. The protection component includes a third motor 29 and symmetrically arranged first protective sleeves 19;

[0037] A motor fixing block 18 is fixedly connected to the inner bottom of the support frame 2. A first motor 17 is fixedly connected to the side of the motor fixing block 18 close to the first slide plate 15. The output end of the first motor 17 is fixedly connected to the first lead screw 16;

[0038] The first slide plate 15 is in threaded connection with the first lead screw 16. A second sliding support frame 14 and a first sliding support frame 13 are respectively fixedly connected to the inner bottom of the support frame 2. The second sliding support frame 14 and the first sliding support frame 13 are slidably connected to the first slide plate 15 together;

[0039] A first chute 9 is formed on the side of the first slide plate 15 close to the magnetic fluid transparent box 5. The first chute 9 is slidably connected to the second slide plate 24. A second chute 25 is formed on the side of the first sliding support frame 13 close to the second lead screw 27. A sliding fixing block 26 is slidably arranged inside the second chute 25;

[0040] A second motor 28 is fixedly connected to the side of the sliding fixing block 26 close to the second lead screw 27. The output end of the second motor 28 is fixedly connected to the second lead screw 27. The second lead screw 27 is in threaded connection with the second slide plate 24.

[0041] In this embodiment, first, during use, the trainer speaks into the microphone 3. Subsequently, the sound signal passes through the microphone 3 and is converted into an electrical signal. The electrical signal controls the rotation of the first motor 17 and the second motor 28 respectively. The rotation of the first motor 17 drives the rotation of the first lead screw 16. The provided first sliding support frame 13 and second sliding support frame 14 guide and limit the first slide plate 15. The rotation of the first lead screw 16 drives the first slide plate 15 that is threadedly connected to it to move. Subsequently, the rotation of the second motor 28 drives the rotation of the second lead screw 27. The rotation of the second lead screw 27 drives the second slide plate 24 to move under the guiding action of the first slide plate 15. At the same time, the movement of the second slide plate 24 drives the movement of the first electromagnet 23. In this way, the electrical signal can control the movement of the first electromagnet 23 in the horizontal X / Y directions. At the same time, the electrical signal controls the magnetic field strength of the first electromagnet 23. The first electromagnet 23 attracts the ferrofluid in the ferrofluid transparent box 5 to perform various movements and morphological changes. According to the different amplitudes, frequencies, and phases of the human speech, the ferrofluid will present different states. Through the provided moving component, the above process can achieve the arbitrary movement of the first electromagnet 23 on the horizontal X / Y coordinates, improve the control effect of the first electromagnet 23 on the ferrofluid, reduce the interference effect. In addition, by controlling the magnetic field size of the first electromagnet 23, precise control of the ferrofluid can be achieved.

[0042] Embodiment Two

[0043] As Figures 1 - 11 shown, based on Embodiment One, both of the two first protective sleeves 19 are fixedly connected to the support frame 2. The second protective sleeves 22 are slidably arranged inside both of the two first protective sleeves 19, and the third protective sleeves 21 are slidably arranged inside both of the two second protective sleeves 22;

[0044] Both sides of the two third protective sleeves 21 close to the ferrofluid transparent box 5 are symmetrically and fixedly connected with electromagnetic blocks 20. The two third protective sleeves 21 are commonly threadedly connected to the bidirectional lead screw 10. A gear 11 is fixedly connected to the central position of the bidirectional lead screw 10;

[0045] A third motor 29 is fixedly connected to the side of the support frame 2 close to the gear 11. The output end of the third motor 29 is fixedly connected with a worm 12. The gear 11 meshes with the worm 12;

[0046] Shielding plates 7 are symmetrically and slidably arranged inside the ferrofluid transparent box 5. Both ends of the shielding plates 7 are symmetrically and fixedly connected with second electromagnets 30. The second electromagnets 30 and the electromagnetic blocks 20 are in the same horizontal and vertical positions;

[0047] Both of the two second protective sleeves 22 and the two third protective sleeves 21 are slidably connected to the fixed square 6. The opening sizes of the two third protective sleeves 21 are adapted to the height size of the ferrofluid transparent box 5.

[0048] In this embodiment, when the external magnetic field interference is strong, the rotation of the third motor 29 can be controlled. The rotation of the third motor 29 drives the rotation of the worm 12. The worm 12 meshes with the gear 11. Therefore, the rotation of the worm 12 drives the rotation of the gear 11. The rotation of the gear 11 drives the rotation of the bidirectional threaded rod 10. The two third protective sleeves 21 are commonly threadedly connected to the bidirectional threaded rod 10. Therefore, the rotation of the bidirectional threaded rod 10 drives the two third protective sleeves 21 to approach each other. At the same time, the movement of the third protective sleeve 21 drives the movement of the second protective sleeve 22 until the entire magnetorheological fluid transparent box 5 is protected, reducing the external electromagnetic interference and affecting the training effect. At the same time, when the device is not in use, the electromagnet 20 and the second electromagnet 30 can be energized so that the electromagnet 20 and the second electromagnet 30 attract each other. At the same time, the rotation of the third motor 29 drives the two third protective sleeves 21 to approach each other. The movement of the third protective sleeve 21 drives the movement of the electromagnet 20. The movement of the electromagnet 20 attracts the second electromagnet 30 to drive the shielding plate 7 to slide inside the magnetorheological fluid transparent box 5. While protecting the magnetorheological fluid transparent box 5, the magnetorheological fluid inside the magnetorheological fluid transparent box 5 can also be aggregated. In the above process, through the provided first protective sleeve 19, second protective sleeve 22 and third protective sleeve 21, when the external electromagnetic interference is strong, the magnetorheological fluid transparent box 5 can be protected by the movement of the third protective sleeve 21, reducing the interference of the external electromagnetic field, making the voice training more stable and improving the training effect. When the device is not in use, through the provided electromagnet 20, under the action of the third motor 29, the two third protective sleeves 21 approach each other to protect the magnetorheological fluid transparent box 5. Subsequently, the provided shielding plate 7 aggregates the magnetorheological fluid, reducing the disturbance of the external environment to the magnetorheological fluid and improving the service life.
