Sealing device and electronic device for microphone volume channel

The utility model belongs to the field of electronic products, and more particularly to a sealing device and an electronic device for a microphone volume channel. Background technique

The sealing of the microphone volume channel is mainly used in the form of foaming cotton on the top of the microphone. The microphone intensive device of a mobile phone as shown in Fig. 1 is in the form of pressing the foam 10 above the microphone 11. This type of structure is simpler and easier to assemble, but the sealing performance is not good. Moreover, this configuration requires the position of the microphone 11 to be at the edge of the main board of the mobile phone, and the distance from the outer surface of the casing 9 is within 5 mm.

For different electronic devices, or other reasons, when the microphone can not be placed on one side of the motherboard, or can not be within 5mm from the surface of the outer casing, the use of press-fit foam will pose a great challenge to the microphone mold, because The sound hole diameter of the microphone is generally between 0.8-lmm, and the pin of the mold is very thin. If the length of the pin is too long, the pin of the mold will break during use, and from now on It is seen that the mold does not have mass production capability in this case.

Therefore, in the prior art, when the microphone sound hole is far from the sound hole of the outer casing, the existing microphone mold does not have the problem of mass production capacity, and an effective solution has not been proposed for this problem. Summary of the invention
