Description

Technical Field

[0001] This utility model relates to the field of microphone technology, specifically to a MEMS sound receiving device and a MEMS microphone. Background Technology

[0002] MEMS (Micro-Electro-Mechanical Systems) microphones are microphones manufactured based on MEMS technology. Specifically, the structure integrates a capacitor onto a micro silicon chip and can be manufactured using surface mount technology. MEMS microphones consist of components such as a microphone and a protective mesh. The protective mesh can reduce airflow noise, thereby ensuring the quality of microphone pickup.

[0003] When in use, the protective mesh cover can also prevent dust, debris, and saliva from directly contacting the microphone. However, it has been found that the protective mesh cover of the existing MEMS radio device is not easy to disassemble, which makes it inconvenient to clean and maintain the protective mesh cover. Therefore, it needs to be improved.

[0004] Therefore, it is necessary to invent a MEMS sound receiving device and a MEMS microphone. Summary of the Invention

[0005] Therefore, this utility model provides a MEMS sound receiving device and a MEMS microphone to solve the problems in the background art.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a MEMS radio receiving device, comprising:

[0007] A base block, the top of which is fixedly connected to a collar, and a mesh cover is provided on the top of the base block, the mesh cover being in contact with the collar;

[0008] The microphone is fixedly connected to the top of the base block;

[0009] A connecting ring is fixedly connected to the inner wall of the mesh cover. A groove is provided on the top of the base block. The groove is ring-shaped. A movable ring is provided inside the groove. The movable ring is in contact with the mesh cover and the bottom of the connecting ring. A plurality of springs are fixedly connected to the bottom of the groove in a circumferentially evenly distributed manner. The top ends of the plurality of springs are fixedly connected to the bottom of the movable ring.

[0010] The base block has multiple slots, each of which is located on a connecting ring and is evenly distributed in a circumferential shape. Multiple L-shaped rods are fixedly connected to the top of the base block, and the outer ends of the L-shaped rods are respectively located in the multiple slots. Protrusions are fixedly connected inside the multiple slots, and the multiple protrusions are in contact with the inner walls of the top of the multiple L-shaped rods.

[0011] Preferably, the mesh cover is in active contact with the collar.

[0012] Preferably, the movable ring is in active contact with the groove, the mesh cover, and the connecting ring.

[0013] Preferably, the L-shaped rod is in active contact with the slot.

[0014] Preferably, the movable ring has multiple circumferentially distributed limiting grooves, each of which has a limiting rod embedded inside, and the bottom ends of the limiting rods are fixedly connected to the bottom of the grooves.

[0015] Preferably, the limiting rod slides in contact with the limiting groove.

[0019] The beneficial effects of this utility model are:

[0020] This utility model, through the design of components such as a connecting ring, an L-shaped rod, a slot, protrusions, and a movable ring, allows the mesh cover to be removed simply by rotating it. This causes the connecting ring and multiple protrusions to rotate, preventing the protrusions from contacting the inner top wall of the L-shaped rod. This releases the L-shaped rod from its resistance to the protrusions, allowing the mesh cover to be easily removed from the base. The removal process is simple and convenient, requiring only a forceful rotation of the mesh cover. This also makes cleaning stains from the mesh cover particularly easy. Attached Figure Description

[0031] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0032] See attached document Figure 1 - Appendix Figure 7 The present invention provides a MEMS radio receiving device, comprising:

[0033] Base block 1, with a collar 2 fixedly connected to the top of base block 1, and a mesh cover 3 provided on the top of base block 1, the mesh cover 3 being in contact with the collar 2;

[0034] Microphone 4 is fixedly connected to the top of base block 1;

[0035] The connecting ring 5 is fixedly connected to the inner wall of the mesh cover 3. The base block 1 has a groove 6 on the top. The groove 6 is ring-shaped. The moving ring 7 is provided inside the groove 6. The moving ring 7 is in contact with the mesh cover 3 and the bottom of the connecting ring 5. Multiple springs 8 are fixedly connected to the bottom of the groove 6 in a circumferentially evenly distributed manner. The tops of the multiple springs 8 are fixedly connected to the bottom of the moving ring 7.

[0036] The card slot 9 is provided in multiple ways. All card slots 9 are opened on the connecting ring 5. The multiple card slots 9 are evenly distributed in a circumferential shape. The top of the base block 1 is fixedly connected to multiple L-shaped rods 10. The outer ends of the multiple L-shaped rods 10 are respectively set in the multiple card slots 9. The inside of the multiple card slots 9 is fixedly connected to protrusions 11. The multiple protrusions 11 are in contact with the inner walls of the top of the multiple L-shaped rods 10.

[0037] The mesh cover 3 is in active contact with the collar 2, the movable ring 7 is in active contact with the groove 6, the mesh cover 3 and the connecting ring 5, and the L-shaped rod 10 is in active contact with the slot 9.

[0038] In this embodiment, when the mesh cover 3 needs to be removed, simply rotate the mesh cover 3 to rotate the connecting ring 5 and the multiple protrusions 11. In this way, the protrusions 11 will not contact the top inner wall of the L-shaped rod 10, thus relieving the L-shaped rod 10 from contacting the protrusions 11. Then the mesh cover 3 can be removed from the base block 1.

[0039] In order to achieve the purpose of stable up and down movement of the moving ring 7, the following technical solution is adopted in this device: multiple circumferentially distributed limiting grooves 12 are opened on the moving ring 7, and limiting rods 13 are embedded in the multiple limiting grooves 12. The bottom ends of the multiple limiting rods 13 are fixedly connected to the bottom of the groove 6. The limiting rods 13 slide in contact with the limiting grooves 12. The design of the limiting rods 13 and the limiting grooves 12 can make the moving ring 7 move up and down stably.

[0040] In order to achieve the purpose of inserting this device into the microphone body 16, the device adopts the following technical solution: the bottom of the base block 1 is provided with a mounting groove 14, and three mounting rings 15 are fixedly connected in the mounting groove 14. The three mounting rings 15 are distributed vertically in a straight line. The design of the mounting groove 14 and the mounting rings 15 allows this device to be inserted into the microphone body 16.

[0041] The usage process of this utility model is as follows: When using the device, install it on the microphone body 16. During installation, align the mounting slot 14 with the top of the microphone body 16 and insert it. Since the mounting slot 14 has three mounting rings 15 and the microphone body 16 has three annular grooves 17, after insertion, the three mounting rings 15 can be engaged in the three annular grooves 17. Thus, the entire device can be installed on the microphone body 16. Figure 6 As shown, when the user speaks into the mesh 3, the microphone 4 can pick up the sound.

[0042] When the mesh cover 3 needs to be removed after a period of use to clean the surface stains, simply rotate the mesh cover 3 forcefully. Rotating the mesh cover 3 will cause the connecting ring 5 and multiple protrusions 11 to rotate, so that the protrusions 11 will not contact the top inner wall of the L-shaped rod 10. This will release the resistance of the L-shaped rod 10 to the protrusions 11, and then the mesh cover 3 can be removed from the base block 1. The removal is simple and convenient, as long as the mesh cover 3 is rotated forcefully. This makes it particularly convenient to clean the stains on the mesh cover 3.

[0043] When the mesh cover 3 needs to be reinstalled, align the multiple slots 9 with the multiple L-shaped rods 10 and insert the mesh cover 3 into the collar 2 until the top of the L-shaped rod 10 contacts the top of the slot 9. While inserting the mesh cover 3 into the collar 2, the moving ring 7 can also be moved downwards, which will compress the multiple springs 8. After insertion, rotate the mesh cover 3 to make the mesh cover 3 and the connecting ring 5 rotate, so that the multiple protrusions 11 can move into the L-shaped rod 10 and contact the top inner wall of the L-shaped rod 10. In this way, the L-shaped rod 10 can pull the connecting ring 5 and the mesh cover 3. Since the multiple springs 8 are compressed, the moving ring 7 can move upwards, and thus push the mesh cover 3 and the connecting ring 5 upwards. In this way, there will be two interacting forces. Through the mutual support of the two forces, the mesh cover 3 can be stably attached to the base block 1, thus completing the installation of the mesh cover 3.

[0044] The above are merely preferred embodiments of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model shall fall within the scope of protection claimed by this utility model.
