[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Reference Figure 1-3, the utility model provides an embodiment: a sound with noise reduction function, including a column 1 and a noise reduction sound 15, the side wall of the column 1 is fixedly connected with a base 2, a concave hole 3 is opened inside the column 1, a sliding rod 4 is slidably connected inside the column 1, a limiting column 5 is fixedly connected inside the sliding rod 4, a limiting rod 6 is fixedly connected inside the limiting column 5, a spring 7 is sleeved on the side wall of the limiting rod 6, one end of the spring 7 is fixedly connected inside the limiting column 5, and the other end of the spring 7 is fixedly connected with a collar 8, the side wall of the collar 8 is slidably connected to the side wall of the limiting rod 6, the side wall of the collar 8 is fixedly connected with a block 9, the side wall of the block 9 is slidably connected to the side wall of the limiting rod 6, the side wall of the block 9 is slidably connected to the side wall of the limiting rod 6, the side wall of the block 9 is slidably connected to the limiting column 5, the side wall of the block 9 is slidably connected to the concave hole 3, the noise reduction sound 15 is arranged on the top of the column 1, and a fixing component is arranged on the top of the column 1.

[0023] At work, we often need to adjust the height of the equipment to adapt to different working environments and needs. When the height of the noise reduction noise 15 needs to be adjusted, the inner wall of the column 1 can be pulled upward to apply pressure to the block 9. This pressure makes the collar 8 slide inward on the side wall of the limit rod 6 and squeeze the spring 1 7. After the block 9 moves to the inside of the limit column 5, we can rotate the slide bar 4 to keep the block 9 inside the limit column 5. By pulling the slide bar 4 upward, the height of the equipment is changed. Then, turn the slide bar 4 back to move the block 9 to the inside of the recessed hole 3. In this process, the spring 1 7 loses the force of extrusion and resets, while driving the block 9 to move. Finally, the block 9 is stuck inside the concave hole 3 to fix the slide bar 4, thereby completing the height adjustment of the device. The noise reduction device 15 is an existing device. When performing noise reduction, a microphone or sensor is used to detect the noise in the surrounding environment, and the detected noise signal is inverted, and a sound wave signal with a phase opposite to the noise is generated, and the reverse sound wave is mixed into the audio output to offset or weaken the influence of external noise. This is usually done through a speaker or a special drive unit.

[0024] Reference Figure 4 The fixing component includes a top plate 10, the lower surface of the top plate 10 is fixedly connected to the upper surface of the column 1, a limiting groove 11 is opened inside the top plate 10, a hole 12 is opened inside the top plate 10, a side plate 13 is fixedly connected to the upper surface of the top plate 10, a slide plate 14 is arranged inside the top plate 10, and the side wall of the slide plate 14 is slidably connected to the inside of the limiting groove 11, a noise reduction noise 15 is arranged on the upper surface of the slide plate 14, a latch 16 is arranged inside the top plate 10, the side wall of the latch 16 is slidably connected to the inside of the hole 12, a spring 2 17 is sleeved on the side wall of the latch 16, one end of the spring 2 17 is fixedly connected to the lower surface of the top plate 10, and the other end of the spring 2 17 is fixedly connected to the limiting plate 18, the side wall of the limiting plate 18 is fixedly connected to the side wall of the latch 16, the side wall of the latch 16 is fixedly connected to a pull ring 19, and the side wall of the slide plate 14 is fixedly connected to a handle 20.

[0025] When repairing the noise reduction device 15, first, by pulling the pull ring 19, the latch 16 can be pulled out of the hole 12 in which it is located. The removal of the latch 16 allows the slide plate 14 to be smoothly pulled out of the limit groove 11, and then the noise reduction device 15 on the slide plate 14 is repaired. When the noise reduction device 15 is repaired and ready to be reinstalled, we pull the latch 16 downward again. Then, push the slide plate 14 back into the limit groove 11 through the handle 20. When the slide plate 14 is fully inserted, release the pull ring 19. At this time, the spring 2 17 will return to its original state, pushing the latch 16 back between the top plate 10 and the slide plate 14, thereby completing the fixation of the slide plate 14. At the same time, a mineral wool interlayer is arranged inside the side plate 13, which has good sound absorption performance and can effectively achieve the effect of noise reduction.

[0026] Working principle: When the equipment is used for work and the height of the noise reduction noise 15 needs to be adjusted, the slide bar 4 can be pulled upwards to make the inner wall of the column 1 apply pressure to the block 9, so that it drives the collar 8 to slide inward on the side wall of the limit rod 6 and squeezes the spring 1 7. After the block 9 moves to the inside of the limit column 5, the slide bar 4 is rotated to make the block 9 always restricted inside the limit column 5. Then, the slide bar 4 is pulled upwards to change the height of the equipment. After the height adjustment is completed, the slide bar 4 is turned back to make the block 9 move to the inside of the concave hole 3. At this time, the spring 1 7 loses the extrusion force and resets, and drives the block 9 to move, and the block 9 is stuck in the inside of the concave hole 3, and the slide bar 4 is fixed to complete the adjustment of the height of the equipment. When When the noise reduction noise 15 is damaged during use and needs to be repaired, the pull ring 19 can be used to pull the pin 16 downward to apply tension to the spring 2 17 to make the pin 16 slide out from the inside of the hole 12, and then the handle 20 can be used to pull the slide plate 14 to pull it out from the inside of the limiting groove 11 to complete the disassembly of the noise reduction noise 15. When the noise reduction noise 15 is repaired and installed, the pin 16 is pulled downward again to slide the slide plate 14 back into the inside of the limiting groove 11. When the slide plate 14 is fully inserted into the inside of the limiting groove 11, the pull ring 19 is released. At this time, the spring 2 17 will lose the tension and reset, and the pin 16 can be inserted into the top plate 10 and the slide plate 14 again to fix the slide plate 14 to complete the installation of the noise reduction noise 15.

[0027] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
