A folding baffle 94 is fixedly connected to the top surface of the spring. A grip is provided at the bottom of the folding baffle 94. A spring protrusion 93 is provided through the surface of the protective outer frame 92.

[0027] A first protection box 10 and a second protection box 11 are respectively provided on both sides of the dustproof protection mechanism 9, a rotating rod 13 is provided inside the first protection box 10 and the second protection box 11, both ends of the rotating rod 13 are provided with an idle bearing seat 14, and the outer side of the rotating rod 13 is fixedly connected with a speaker 12; a device box 4 is provided above the first protection box 10 and the second protection box 11, a battery is provided inside the device box 4, fill lights 3 are provided on both sides of the device box 4, a receiving groove 7 is provided inside the device box 4, a sound receiving microphone 8 is placed inside the receiving groove 7, a slide groove 5 is provided on the inner wall of the slide groove 7, and a baffle 6 is provided inside the slide groove 5.

[0028] When in use, after slightly pulling down the folding baffle 94, press the spring protrusion 93 so that the spring protrusion 93 releases the clamping connection with the handle, causing the spring inside the guide groove 95 to rebound, pushing the folding baffle 94 to retract, allowing the display 91 to be used normally.

[0029] The lifting and lowering adjustment mechanism 2 includes a slider 21, a lifting and lowering controller 24 and a threaded rod 22. The slider 21 is fixedly connected to both sides of the table top 1. A lifting and lowering controller 24 is arranged below the slider 21. The lifting and lowering controller 24 is fixedly arranged on the bottom surface of the table top 1. The internal thread of the slider 21 is penetrated by a threaded rod 22. An adjustment groove 23 is arranged on the outside of the threaded rod 22. A rotating motor is connected to one end of the threaded rod 22. An isolation single panel 25 is arranged on the outside of the adjustment groove 23. The rotating motor is controlled to rotate by the lifting and lowering controller 24, thereby driving the threaded rod 22 to rotate and fit the internal thread of the slider 21, so that the height of the table top 1 can be adjusted along the adjustment groove 23 through the slider 21 to adapt to the standing height of the user.

[0030] The isolation single room panel 25 is in a C-shape, the fill lights 3 are symmetrically arranged on both sides of the inner wall of the isolation single room panel 25, the rotating motor is electrically connected to the lifting controller 24, the top surface area of ​​the table top 1 is smaller than the surface area of ​​the inner rectangle of the isolation single room panel 25, and the equipment box 4 is fixedly connected to the isolation single room panel 25.

[0031] The speaker 12 inside the first protection box 10 is connected to the display 91, and the speaker 12 inside the second protection box 11 is connected to the sound pickup microphone 8; the speaker 12 inside the first protection box 10 is connected to the display 91 to play standard English audio for easy proofreading and learning.

[0032] The shape of the spring protrusion 93 is L-shaped, and the size of the spring protrusion 93 matches the size of the handle. The display device main box 98 is fixedly connected to the top surface of the table top 1, and the spring protrusion and the handle are clamped together to achieve the limiting fixation of the folding baffle 94.

[0033] Working principle: Before use, connect the device to the power supply to ensure that the device can be used normally; when in use, use the lifting controller 24 to control the rotation of the rotary motor, thereby driving the threaded rod 22 to rotate and fit the thread inside the slider 21, so that the table top 1 can be adjusted in height along the adjustment slot 23 through the slider 21 to adapt to the user's standing height, and then use the hand to turn the speaker 12 to rotate the speaker 12 to a position relative to the user, turn on the fill light 3, and then pull the folding baffle 94 slightly downward, press the spring protrusion 93, so that the spring protrusion 93 releases the clamping connection with the handle, so that the spring inside the guide slot 95 rebounds, pushing the folding baffle 94 to shrink, so that the display 91 can be used normally, and finally the baffle 6 Slide along the slide groove 5 to take out the sound-collecting microphone 8 from the inside of the receiving groove 7 for use, so as to record the oral practice. At the same time, because the shape of the isolation single room board 25 is relatively closed, the external interference in the sound collection process is reduced; when idle, pull the folding baffle 94 downward to compress the spring, and then align the position of the handle with the spring protrusion 93 and release it, so that the spring protrusion and the handle are locked together, and then the sound-collecting microphone 8 is protected inside the receiving groove 7, and the baffle 6 is slid closed to protect the microphone 8, and finally the speaker 12 is moved by hand to be transferred into the first protection box 10 and the second protection box 11 for storage, thereby solving the problem of dust easily falling when the device is idle.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
