[0023] 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.

[0024] Reference Figure 1-2 The utility model provides an embodiment: a noise collection device for noise detection, including a bottom plate 1. First, the bottom plate 1 is placed in a suitable position, the top of the bottom plate 1 is fixedly connected to a host 2, the top left side of the host 2 is fixedly connected to a sound receiver 3, and the top left side of the host 2 is provided with a protective cover 4. Then, the protective cover 4 is placed outside the sound receiver 3, and cavities 5 are opened inside the four corners of the protective cover 4. A push plate 6 is slidably connected inside the cavity 5, and a pull plate 7 is fixedly connected to the top of the push plate 6. Then, the pull plate 7 is pressed downward.

[0025] A telescopic component is provided at the bottom of the push plate 6, and the telescopic component includes two connecting shafts 8, two card plates 9 and a spring 10. One end of the two connecting shafts 8 is rotatably connected to the bottom of the left and right ends of the push plate 6. Under the pressure of the pull plate 7, the push plate 6 presses the spring 10 downward. The top of the two card plates 9 is rotatably connected to the bottom end of the connecting shaft 8, and the outside of the card plate 9 is slidably connected to the inner wall of the card plate 9. The outside of the pull plate 7 is slidably connected to the top through hole of the protective cover 4. The spring 10 is arranged inside the cavity 5. When the spring 10 is compressed, it absorbs external force due to its own elastic properties. One end of the spring 10 is fixedly connected to the bottom of the push plate 6, and the other end of the spring 10 is fixedly connected to the bottom of the cavity 5. A slide groove 11 is opened inside the protective cover 4. At the same time, the connecting shaft 8 is rotated to make the two card plates 9 slide inside the slide groove 11.

[0026] A plurality of card slots 12 are provided on the left side of the top of the host 2. When the protective cover 4 can be placed in the card slot 12, the outer portion of the card plate 9 is engaged with the inner wall of the card slot 12, and the pull plate 7 is released. At this time, the spring 10 will release the external force absorbed during compression, so that the card plate 9 is engaged with the card slot 12. In this way, the protective cover 4 can be fixed to the top of the host 2, reducing the influence of foreign objects on the sound receiver 3, realizing the protection of the sound receiver 3, reducing the influence of dust and impurities entering the sound receiver 3, and at the same time, the protective cover 4 can be quickly disassembled for cleaning to ensure the protection effect.

[0027] Reference Figure 1 and Figure 3 When the base plate 1 is placed, the base will first contact the ground. Buffer components are arranged at the four corners of the bottom end of the base plate 1. The buffer components include a fixed column 13, a sliding column 14, a damper 15 and a spring 16. The top of the fixed column 13 is fixedly connected to the bottom of the base plate 1, and the outside of the sliding column 14 is slidably connected to the inside of the fixed column 13. At the same time, when the sliding column 14 is squeezed, it will slide inside the fixed column 13. The bottom of the damper 15 is fixedly connected to the inner wall of the bottom end of the sliding column 14. At this time, the damper 15 absorbs and disperses energy to reduce the vibration amplitude and impact force of the system. One end of the spring 16 is fixedly connected to the inner wall of the top end of the fixed column 13, and the other end of the spring 16 is fixedly connected to the bottom of the damper 15. The elastic characteristics of the spring 16 are used for buffering to reduce the sliding of the bottom and affect the sound reception effect.

[0028] The left and right sides of the sliding column 14 are fixedly connected with a limit plate 17. During the sliding process, the limit plate 17 can limit the sliding column 14. The outer part of the limit plate 17 is slidably connected to the inner wall of the fixed column 13 to prevent the sliding column 14 from separating from the fixed column 13, thereby achieving buffering of the bottom of the base plate 1 and reducing the impact on the sound receiving effect of the microphone 3 when the bottom is hit. The bottom of the four sliding columns 14 is fixedly connected with a base, and the bottom of the base is fixedly connected with an anti-skid pad. The stability of the base plate 1 can be increased by the base and the anti-skid pad.

[0029] Working principle: first, place the bottom plate 1 in a suitable position, then place the protective cover 4 on the outside of the sound receiver 3, then press the pull plate 7 downwards, and the push plate 6 presses the spring 10 downwards under the pressure of the pull plate 7. The spring 10 absorbs external force due to its own elastic properties when it is compressed. At the same time, the connecting shaft 8 rotates to make the two card plates 9 slide inside the slide groove 11. When the protective cover 4 can be placed inside the card groove 12, release the pull plate 7. At this time, the spring 10 will release the external force absorbed during compression, so that the card plate 9 and the card groove 12 are locked. The protective cover 4 can be fixed on the top of the host 2 to reduce the influence of foreign objects on the sound receiver 3. When the base plate 1 is placed, the base will first touch the ground. At this time, the damper 15 absorbs and disperses energy to reduce the vibration amplitude and impact force of the system, and cooperates with the elastic characteristics of the spring 16 for buffering to reduce the sliding of the bottom and the influence of the sound receiving effect. At the same time, when the sliding column 14 is squeezed, it will slide inside the fixed column 13. During the sliding process, the limit plate 17 can limit the sliding column 14 to prevent the sliding column 14 from separating from the fixed column 13.

[0030] 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. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
