[0020] In order to enable those skilled in the art to better understand the solution of the utility model, the technical solution in the embodiment of the utility model will be clearly and completely described below in conjunction with the accompanying drawings.

[0021] like Figure 1-3 As shown, the utility model is an electronic device with a microphone waterproof structure, including an electronic device body 1, a sound receiving hole 11 is arranged on the electronic device body 1, a sound receiving channel 12 whose inner wall cooperates with the sound receiving hole 11, a waterproof breathable part is fixedly arranged in the sound receiving channel 12, the waterproof breathable part includes a waterproof breathable membrane 13 and an air membrane fixing part 14, the waterproof breathable membrane 13 can block the sound receiving hole 11, and a microphone assembly 15 is fixedly arranged at one end of the sound receiving channel 12 away from the sound receiving hole 11.

[0022] The waterproof breathable membrane 13 can effectively prevent water from entering the electronic device body 1 through the sound receiving hole 11 and affecting the normal use of components. In addition, with the cooperation of the air membrane fixing part 14, the stability of the waterproof breathable membrane 13 in the sound receiving channel 12 can be effectively guaranteed.

[0023] The air film fixing member 14 can be fixed to the sound receiving channel 12 by glue dispensing, so as to further improve the waterproof sealing effect at the sound receiving hole 11 .

[0024] The microphone assembly 15 includes a mounted microphone 151, a mounting plate 152 and a flexible circuit board 153. The flexible circuit board 153 and the mounted microphone 151 are both arranged on the mounting plate 152. The mounting plate 152 is provided with a sound pickup hole 1521 that cooperates with the mounted microphone 151. The mounted microphone 151 is arranged on the side of the mounting plate 152 away from the sound receiving channel 12.

[0025] By attaching the mounted microphone 151 to the side of the mounting plate 152 away from the sound receiving channel 12 , the sound can be captured more directly in cooperation with the sound receiving hole 11 and the sound receiving channel 12 .

[0026] The mounting plate 152 is covered at the end of the sound receiving channel 12 to block the sound receiving channel 12 and prevent water from entering the interior of the product.

[0027] The mounted microphone 151 is a micro-electromechanical system microphone, which is provided with a sound pickup hole, which is aligned with the sound pickup through hole 1521. The mounted microphone 151 is a micro-electromechanical system microphone, and a circle of waterproof glue is provided on the periphery thereof, which can ensure that liquid does not flow into the electronic device body 1 from the sound pickup through hole 1521.

[0028] Glue is injected around the side of the mounted microphone 151 by dispensing to prevent water from entering the electronic device body 1 through the sound pickup through hole 1521 .

[0029] The electronic device with a microphone waterproof structure also includes a sealing elastic member 16, which is arranged in the sound receiving channel 12, and the sealing elastic member 16 is arranged between the waterproof breathable member and the microphone assembly 15, and a sound guide hole 161 is arranged on the sealing elastic member 16, and the sound guide hole 161 can guide the sound of the waterproof breathable membrane 13 to the sound pickup through hole 1521.

[0030] By setting the sealing elastic member 16, the waterproof breathable member can be further fixed, and at the same time, the mounting plate 152 presses the sealing elastic member 16 onto the waterproof breathable member, so that when the waterproof breathable membrane 13 is damaged, water can only flow from the sound receiving hole 11 into the sound guide hole 161 and then into the sound pickup through hole 1521. Since the mounted microphone 151 is glued to the mounting plate 152, the water can be blocked on the mounted microphone 151, and only a single mounted microphone 151 is damaged, thereby avoiding greater cost losses.

[0031] A positioning column 121 is disposed at one end of the sound receiving channel 12 facing the microphone assembly 15 , and a positioning hole 1522 matching with the positioning column 121 is disposed on the mounting plate 152 .

[0033] There are two groups of positioning posts 121 , and the two groups of positioning posts 121 are symmetrically arranged. The design of the two groups of positioning posts 121 can improve the stability of the installation of the microphone assembly 15 .

[0034] The mounting plate 152 is a steel plate. Two screw holes are arranged on the mounting plate 152. A nut groove is arranged on the sound receiving channel 12. The mounting plate 152 can be fixedly connected to the nut groove by screws passing through the screw holes.

[0035] The provision of the steel plate can ensure the service life of the mounting plate 152 and prevent deformation of the sealing elastic member 16 due to long-term use that affects the waterproof effect.

[0036] The fixing member is a fixed foam. There are two groups of fixed foams. The two groups of fixed foams are respectively arranged on the front and rear end surfaces of the waterproof breathable membrane 13 . The fixed foams are provided with sound-transmitting holes that cooperate with the waterproof breathable membrane 13 .

[0037] By setting the fixed foam, the waterproof breathable membrane 13 can be fixed efficiently, avoiding damage to the waterproof breathable membrane 13 caused by direct mounting, stabilizing the waterproof breathable membrane 13 while controlling the increase in cost during the installation process.

[0038] The waterproof breathable membrane 13 is a nano waterproof breathable membrane 13, which can effectively isolate water or water vapor without affecting sound conduction.

[0039] From the above, it can be seen that the beneficial effect of the utility model is: the use of its mechanism can effectively solve the problem of liquid entering the microphone structure of electronic equipment in the prior art and causing product damage. By using this product structure, the sound receiving hole 11 can be effectively sealed through the waterproof and breathable membrane 13, reducing the possibility of water entering the interior of the product, effectively increasing the service life of the product, improving the user experience, and helping to improve the competitiveness of the product.

[0040] The specific implementation methods described above are preferred implementation methods of the present utility model, and are not intended to limit the specific implementation scope of the present utility model.
