The crossbar 16 can provide support for the rectangular shell 1801 through the damping universal joint 17. The double-headed joint inside the rectangular shell 1801 can be rotated by the knob 1803. The lead screw 1802, a double-ended lead screw 1802, can control the two clamping rods 1806 to move in opposite directions through the slider 1804, thereby increasing the distance between the two clamping rods 1806, making it easier to place the microphone 10 between the two clamping rods 1806. By rotating the double-ended lead screw 1802 in the opposite direction through the knob 1803, the clamping rods 1806 can clamp the microphone 10 through the clamping groove 1807. The rubber pad can increase the fit and friction between the microphone 10 and the clamping groove 1807, making it less likely for the microphone 10 to loosen or fall off.

[0030] In this embodiment, preferably, a battery 4 is fixedly installed on the inner wall of one side of the recorder housing 3, a charging port is embedded on one side of the recorder housing 3, an audio processing module 5 and a storage and transmission module 6 are fixedly installed inside the recorder housing 3, an earphone jack 7 and a USB interface 8 are provided on the other side of the recorder housing 3, a cover 9 is fixedly installed on the surface of the recorder housing 3 by screws, a protective cover 12 is fixedly installed on the surface of the adjustment box 11 by screws, sliding bearings 19 are fixedly installed on both sides of the top of the adjustment box 11, the column 13 is slidably connected to the sliding bearings 19, the battery 4 can be used as a mobile power source, the audio processing module 5 can be used for noise reduction and audio enhancement by connecting it to the microphone 10, the storage and transmission module 6 supports local storage and can transmit data to a computer or mobile phone, and the USB interface 8 and the earphone jack 7 facilitate audio export and real-time monitoring;

[0031] In this embodiment, preferably, casters 2 are fixedly installed at the four corners of the bottom of the base plate 1, and a wheel brake is provided on one side of the casters 2, so that the base plate 1 can be moved easily by the casters 2.

[0032] In use, firstly, rotate the double-ended lead screw 1802 inside the rectangular shell 1801 by the knob 1803 of the clamping assembly 18. The double-ended lead screw 1802 can control the two clamping rods 1806 to move in opposite directions through the slider 1804, thereby increasing the distance between the two clamping rods 1806. Then, place the microphone 10 between the two clamping rods 1806, and then rotate the double-ended lead screw 1802 in the opposite direction by the knob 1803. The clamping rods 1806 can clamp the microphone 10 through the clamping groove 1807. The rubber pad can increase the fit and friction between the microphone 10 and the clamping groove 1807, making it less likely for the microphone 10 to loosen or fall off, thus allowing for quick installation. After that, connect the microphone 10 to the recording box 3 through the wire. It can record the students' singing voices during vocal music teaching. The audio processing module 5 can be used for noise reduction and audio enhancement. The storage and transmission module 6 supports local storage and can transmit data to a computer or mobile phone for convenient playback analysis and guidance.

[0033] When the height of the microphone 10 needs to be adjusted, the motor 1401 of the drive assembly 14 drives the worm gear 1402. The worm gear 1402 drives the lead screw 1404 to rotate through the worm wheel 1403. The lead screw 1404 converts the rotational motion into the linear motion of the lifting platform 1406 through the nut 1405. During the lifting process, the lifting platform 1406 can control the extension and retraction of the column 13, so that the height of the microphone 10 can be automatically adjusted and the height of the column 13 can be self-locked. After the height of the microphone 10 is adjusted, its angle can be freely adjusted through the damping universal joint 17.

[0034] When it is necessary to remove the microphone 10, turn the double-ended screw 1802 again by turning the knob 1803 to release the clamp 1806 and remove the microphone 10.
