[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see the appendix Figure 1 - Appendix Figure 6A microphone voice acquisition module equipped with a vibration sensor includes a module body 1 and a vibration sensor body 4. A microphone unit 2 is provided on the rear inner wall of the module body 1. A pin 3 is provided on the top front side of the module body 1. A fixing and disassembly assembly 5 is provided on the bottom of the vibration sensor body 4. The fixing and disassembly assembly 5 includes a module base 501, a metal plate 503, a torsion block 507 and a slide bar 512. The module base 501 is fixedly installed on the top of the module body 1 and located behind the pin 3. The vibration sensor body 4 is connected to a positioning pin 505 and a strong magnetic plate 506 through the sensor base 504. The torsion block 507 is connected to a moving block 509 through a bidirectional lead screw 508. The moving block 509 is connected to a clamping block 511 through a rubber pad 510.

[0018] Microphone unit 2 is the core sound pickup element, installed on the rear inner wall of module body 1. It is responsible for converting sound signals into electrical signals and is the basic component for voice acquisition. Pin 3 is located on the top front side of module body 1 and serves as an electrical signal interface.

[0019] The top of the module base 501 is provided with a positioning groove 502, the metal sheet 503 is fixedly connected to the inner wall of the top middle of the module base 501, and the sensor base 504 is fixedly connected to the bottom of the vibration sensor body 4.

[0020] The sensor base 504 is fixedly connected to the bottom of the vibration sensor body 4. It is a transition structure connecting the vibration sensor body 4 and the module base 501, and integrates the installation interface with functions such as positioning, magnetic attraction, and clamping.

[0021] The positioning pin 505 is fixedly connected to the bottom of the sensor base 504, the strong magnetic sheet 506 is fixedly connected to the middle of the bottom of the sensor base 504, and the outer wall of the positioning pin 505 is slidably connected to the inner wall of the positioning groove 502.

[0022] The rubber pad 510 is fixed to the inner side of the clamping block 511. When it contacts the top of the sensor base 504 and the bottom of the module body 1, it increases the friction through elastic deformation to prevent loosening and avoid component wear or vibration transmission interference caused by hard contact.

[0023] The strong magnetic sheet 506 is magnetically connected to the metal sheet 503. One end of the bidirectional lead screw 508 is fixedly connected to the surface of the torsion block 507, and the other end of the bidirectional lead screw 508 is rotatably connected to the bottom right side of the sensor base 504. The slide rod 512 is fixedly installed at the bottom of the sensor base 504 and located behind the bidirectional lead screw 508. One end of the moving block 509 is threadedly connected to the outer wall of the bidirectional lead screw 508, and the other end of the moving block 509 is slidably connected to the outer wall of the slide rod 512. The surface of the moving block 509 is fixedly connected to the outer wall of the rubber pad 510. The rubber pad 510 is fixedly connected to the inner side of the clamping block 511. The inner side of the rubber pad 510 is in contact with the top of the sensor base 504 and the bottom of the module body 1, respectively.

[0024] The slide bar 512 is fixed to the bottom of the sensor base 504, which can limit the movement direction of the moving block 509, so that the moving block 509 can only translate along the axial direction, preventing the moving block 509 from rotating with the bidirectional lead screw 508, and ensuring that the clamping action is stable and reliable.

[0025] Specifically, through the fixed disassembly component 5, the positioning pin 505 and the positioning groove 502 are quickly aligned to prevent displacement. The strong magnetic sheet 506 and the metal sheet 503 provide temporary fixation through magnetic attraction. It can be operated without manual support, simplifying the steps and improving efficiency. The operator rotates the torsion block 507 to drive the bidirectional lead screw 508 to rotate, so that the moving block 509 moves along the slide bar 512. The clamping block 511 is locked by the rubber pad 510. With the help of magnetic attraction, double fixation is achieved to prevent loosening when the equipment vibrates. When disassembling, the torsion block 507 is rotated in the opposite direction to separate the moving block 509 and remove the vibration sensor body 4 by overcoming the magnetic attraction. The whole process is manual and requires no tools. It is suitable for frequent disassembly and assembly scenarios, and takes into account both sturdiness and convenience.

[0026] Please see the appendix Figure 1 Appendix Figure 3 Appendix Figure 4 and appendix Figure 7 The vibration sensor body 4 is provided with a protective component 6 on its exterior. The protective component 6 includes a cylindrical protective cover 601. The cylindrical protective cover 601 is fixedly installed on the top of the sensor base 504 and the vibration sensor body 4 is disposed inside the cylindrical protective cover 601.

[0027] A transparent observation window 602 is set on the outer wall of the cylindrical protective cover 601 and is made of transparent material, allowing users to directly observe the working status of the internal vibration sensor body 4 without disassembling the cylindrical protective cover 601, such as whether it is loose, damaged, or the status of the indicator lights, which facilitates daily inspection and maintenance.

[0028] A transparent observation window 602 is provided on the outer wall of the cylindrical protective cover 601. Multiple sets of small drainage holes 603 distributed in a circle are opened on the lower part of the outer wall of the cylindrical protective cover 601. A metal filter screen 604 is provided on the inner top wall of the cylindrical protective cover 601. A non-woven fabric filter layer 605 is provided on the top of the metal filter screen 604.

[0029] The small drainage holes 603 are located on the lower part of the outer wall of the cylindrical protective cover 601. They are circular and have a small diameter. Their main function is to drain any small amount of water that may seep into the cylindrical protective cover 601, such as condensation or splashing water, to prevent water accumulation from corroding or short-circuiting the vibration sensor body 4, and to prevent foreign objects from entering due to excessively large hole diameter.

[0030] Specifically, through the protective component 6, the cylindrical protective cover 601 is fixed to the top of the sensor base 504, covering the vibration sensor body 4, blocking direct collision and friction from external objects, and playing a basic physical protection role. The metal filter 604 on the inner wall of its top prevents larger solid impurities from entering, and the non-woven filter layer 605 on the top of the metal filter 604 filters fine dust and moisture, maintaining the air permeability inside the cylindrical protective cover 601, avoiding pollutants from affecting the sensitivity of the vibration sensor body 4, and ensuring its long-term stable operation.

[0031] Working principle of this utility model: This utility model is a microphone voice acquisition module equipped with a vibration sensor. First, during installation, the operator aligns the positioning pin 505 on the sensor base 504 at the bottom of the vibration sensor body 4 with the positioning groove 502 on the top of the module base 501, allowing the positioning pin 505 to slide into the positioning groove 502 for initial alignment. At this time, the strong magnetic sheet 506 in the middle of the bottom of the sensor base 504 is magnetically connected to the metal sheet 503 on the inner wall of the top of the module base 501, forming a temporary fixation, allowing subsequent operations to be performed without manual support. Next, the operator rotates the torsion block 507, driving the bidirectional lead screw 508 to rotate, causing the moving block 509 sleeved on the bidirectional lead screw 508 to move towards the center along the slide rod 512. The moving block 509 drives the clamping block 511 to move, and the rubber pad 510 on the inner side of the clamping block 511 makes tight contact with and locks the top of the sensor base 504 and the bottom of the module body 1, achieving double magnetic attraction. Once the vibration sensor body 4 is fixed in place, the microphone unit 2 converts the sound signal into an electrical signal during the operation of the module body 1. This signal is then transmitted to an external device via pin 3. The vibration signal detected by the vibration sensor body 4 is also transmitted through the relevant structure and output via pin 3. Simultaneously, the protective component 6 takes effect. The cylindrical protective cover 601 blocks external collisions and friction, the metal filter 604 and the non-woven fabric filter layer 605 filter impurities and moisture, the transparent observation window 602 facilitates observation of the internal state, and the small drainage hole 603 drains internal water, ensuring the stable operation of the vibration sensor body 4. When it is necessary to disassemble the vibration sensor body 4, the operator rotates the torsion block 507 in the opposite direction. The bidirectional lead screw 508 drives the moving block 509 to separate along the slide bar 512, the clamping block 511 is released from its locked state, and then the magnetic attraction of the strong magnetic sheet 506 and the metal sheet 503 is overcome to remove the positioning pin 505 from the positioning groove 502, thus removing the vibration sensor body 4.

[0032] Finally, it should be noted that the above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
