Description

Technical Field

[0001] The utility model relates to the technical field of silicon microphones, and in particular to a cover-type silicon microphone waterproof protection component. Background Art

[0002] A canopy silicon microphone (also called a packaged silicon microphone or a shrouded silicon microphone) is a special silicon microphone design that adds an external canopy or protective shell to the silicon microphone. This canopy not only provides physical protection to prevent dust, moisture and other contaminants from entering the microphone, but also plays an acoustic optimization role.

[0003] There are some disadvantages in the use of existing devices. For example, there is a problem with the waterproof structure. Since the structural design of the silicon microphone is relatively fixed, many models do not have a special waterproof structure. This makes the silicon microphone susceptible to moisture intrusion when used in a humid or watery environment, causing damage to the internal components, thereby affecting its service life. In addition, since the structure of the silicon microphone is compact and fixed, it is usually not easy to disassemble and assemble, which makes it relatively difficult to inspect and repair the internal components of the silicon microphone. Once the silicon microphone fails, professionals may need to use specific tools to disassemble and repair it, which undoubtedly increases the complexity and cost of the repair. Utility Model Content

[0004] The purpose of the utility model is to provide a cover-type silicon microphone waterproof protection component to solve the problem that since the structural design of silicon microphones is relatively fixed, many models do not have a special waterproof structure, which makes the silicon microphones susceptible to moisture intrusion when used in a humid or watery environment, causing damage to internal components and thus affecting their service life.

[0005] The utility model provides the following technical solution: a cover-type silicon microphone waterproof protection component, comprising a circular bottom plate, a base is fixedly installed on the upper end surface of the circular bottom plate, a silicon microphone component is arranged on the upper end surface of the base, a protective shell is arranged on the upper end surface of the base, a sound receiving port is opened at the top of the protective shell, a waterproof component is arranged on the inner side of the sound receiving port, the silicon microphone component is located on the inner side of the protective shell, and a limited position fixing component is arranged in a rectangular array on the upper end surface of the circular bottom plate for fixing the protective shell and the base.

[0006] In the above scheme, when installing the circular base plate, align the plug with the port at the top of the slot and insert it until the plug is completely accommodated in the slot, and then screw the cover body into the main shell so that the cover body fixes the plug block to prevent the plug block from moving up and down. In this way, the circular base plate is firmly fixed to the inside of the main shell, and the protective shell is firmly fixed to the base through the set limit fixing assembly. The protective shell plays a role in protecting the internal structure and can effectively isolate dust, moisture and other impurities in the external environment, thereby ensuring the stability and reliability of the silicon microphone.

[0007] Furthermore, the silicon microphone assembly includes a silicon microphone body fixed on a base surface, a sensor is provided on the base surface of the base and located on the front side of the silicon microphone body, and the silicon microphone body and the sensor are electrically connected.

[0008] In the above scheme, in actual use, when sound waves enter through the opening of the silicon microphone body, the sensor converts them into corresponding electrical signals.

[0009] Furthermore, the waterproof component includes a dustproof filter plate fixedly installed on the inner side of the sound receiving port, and a TPU film is adhered and fixed to the upper end surface of the dustproof filter plate.

[0010] In the above scheme, the dust-proof filter plate is set to prevent dust from entering the protective shell. The TPU film can effectively fit the surface of the dust-proof filter plate without bubbling. The TPU film is made of thermoplastic polyurethane elastomer rubber, has excellent flexibility, good impact resistance, good wear resistance, good waterproofness, and is recyclable with little impact on the environment. At the same time, the soft TPU material can effectively fit the curved surface without bubbling and can be used for a long time.

[0011] Furthermore, the limit fixing assembly includes a damping shaft rotatably connected to the circular base plate, a limit sleeve is fixedly sleeved on the top outer wall of the damping shaft, a group of upper fixing rings are fixedly connected to the two opposite outer walls of the bottom of the protective shell, and a group of lower fixing rings are fixedly connected to the two opposite outer walls of the base, the upper fixing rings and the lower fixing rings are used in combination and positioning pins are inserted on the inner side.

[0012] In the above scheme, the positioning pin is limited and fixed by manually rotating the limit sleeve. When the limit sleeve is not in use, the end of the limit sleeve is not located directly above the positioning pin. When the limit sleeve is in use, the end of the limit sleeve is located directly above the positioning pin. In this way, the positioning pin can be firmly fixed in the corresponding upper fixing ring and lower fixing ring, thereby avoiding separation of the protective shell and the base.

[0013] Furthermore, the limiting sleeve is rotated 0° or 90° through the damping shaft.

[0014] In the above solution, when the limit sleeve is rotated 0°, the end of the limit sleeve is not located directly above the positioning pin, and when the limit sleeve is rotated 90°, the end of the limit sleeve is located directly above the positioning pin.

[0015] Furthermore, the outer surfaces of the protective shell and the base are coated with waterproof coating.

[0016] In the above scheme, the main function of the waterproof coating is to prevent moisture from penetrating into the interior of the protective shell and the base, thereby preventing moisture from damaging the internal electronic components, mechanical structures, etc.

[0017] Furthermore, a rectangular positioning opening is provided on the upper end surface of the base, and a rectangular positioning frame is fixedly connected to the lower end surface of the protective shell.

[0018] In the above solution, the rectangular positioning opening is used to accommodate the rectangular positioning frame, so as to avoid difficulty in aligning the upper fixing ring and the lower fixing ring.

[0019] Compared with the prior art, the beneficial effects of the utility model are:

[0020] In the utility model, the protective shell is firmly fixed on the base by means of a limiting fixing assembly. The setting of this structure facilitates the removal or maintenance of the silicon microphone body. The protective shell plays a role in protecting the internal structure and can effectively isolate dust, moisture and other impurities in the external environment, thereby ensuring the stability and reliability of the silicon microphone.

[0021] In the utility model, the TPU film is made of thermoplastic polyurethane elastomer rubber, has excellent flexibility, good impact resistance, good wear resistance, good waterproofness, and is recyclable with little impact on the environment; at the same time, the soft TPU material can effectively fit the curved surface without blistering and can be used for a long time.
