As today’s high-volume consumer electronics products, mobile phone manufacturers basically have their own waterproof mobile phone brands, and there are also outdoor dedicated three-proof mobile phones (dust-proof, waterproof and drop-proof). Major mobile phone manufacturers are A lot of effort has been spent on the waterproof treatment of the mobile phone, in order to ensure that the mobile phone can be used normally under various accidents (splashing in water, accidentally falling into the water, rain and snow, etc.), and its performance is not affected. So how does the mobile phone waterproof solution work?
Mobile phone waterproof and sound-permeable components
The waterproofing of mobile phones is actually very simple to say. Nowadays, the commonly used method for waterproof mobile phones is to process sealant and rubber seals or silicone seals to realize the waterproof shell structure. The sound hole is waterproof and sound-permeable, and the circuit board is waterproof by adding nano-coating on the motherboard. Usually mobile phones are easy to enter the weak links or parts: the sound-transmitting holes of the earpiece, speaker, microphone and other sound-producing parts on the phone case. This is because if the waterproof and sound-permeable components of the mobile phone, that is, the waterproof membrane material of the mobile phone, do not pass the test, for the handset, speaker, microphone, etc., the waterproof sound-permeable components of the mobile phone are placed in the mobile phone shell for waterproofing. If the waterproof membrane material of the mobile phone reaches the corresponding dustproof and waterproof level, and can ensure that the sound transmission is not affected, then the waterproof of the mobile phone is also done, so the waterproof and sound-permeable components of the mobile phone can ensure that the mobile phone is not used normally in unexpected situations. Affected.
