Existing mobile phone waterproof technique:

By taking apple 7 as an example: the waterproof ability of 7 Plus of apple iPhone still improves very greatly, is continuing to use tooling and technique Under the technology path of all very complicated [mobile phone side dress device+panel merges with bottom case], exhaust effort: apple devises proprietary Waterproof device is i.e.: waterproof USB, earphone base (can be omitted), waterproof stir two-state switch and waterproof deck hatch door；Do not stint with filling It seals to strengthen the sealing of up-down structure, courageously uses 8 sealing rings: deck hatch door sealing ring, loudspeaker sealing ring, waved switch Sealing ring, HOME key sealing ring, side key sealing ring and loudspeaker sealing ring etc..

Problem is: single cabin waterproof must be coped with comprehensive: the pressure leak of nanometer membrane material principle is that it promotes weakness！ And at present the structure of apple still can not balancing water pressure, the very good acoustic resistance to audio of waterproof is just big, another difficult point of problem It is that nano-sized hydrophobic membrane material of breathing freely liquidates and hits and big differential water pressures are sensitive, seepage flow can not ensure underwater normal use；Under taking into account The actual effect of apple 7 has accomplished that 1 meter of depth of water adheres to a moment, already belongs to and is not easy.

There is no problem (cannot rinse to hole pattern urgency water flow) for normal unhurried current clear water flushing, but surfing (not immersing in seawater) is surveyed After iPhone7 Plus 30 minutes, the audio system of the equipment can not work.

Although the series of iPhone 7 in this year supports IP67 grade water proof and dust proofs, apple is will not to mention under water 1 after intaking Complete immersion 30 minutes of meter ampere are for after service.

Message is interrogated according to Sina's science and technology, it is little that 7 Plus of apple iPhone has the problem of waterproof ability, mobile phone gets wet.And Still be not suitable for underwater use.It is said that: iPhone 7 can adhere to 30 minutes under water in 1 meter of depth, but apple official it is not recommended that this Sample is done.And having a water inlet indicating label inside 7 iPhone of apple, touching water can change colour.

Playback speaker is directly pulled and connected in 2 regions of the ventilative membrane material point of nano-sized hydrophobic that apple uses, a region, another area Domain for Mike and separates inner space and the external world, it should say: for the needs of mobile phone inside and outside air pressure balance, interior of mobile phone is empty Between with the external world to keep certain gas connectivity.

But nano-sized hydrophobic breathes freely membrane material under biggish water pressure, still can leak, waterproof ability is restricted.

[summary of the invention]

The technological deficiency of mobile phone waterproof at present: it actually or by nano-sized hydrophobic breathes freely membrane material and outer in interior of mobile phone space Boundary will keep certain gas connectivity, and nano-sized hydrophobic breathe freely membrane material block under loudspeaker small speaker (BOX) ponding It is difficult to exclude, causes waterproof ability deviation.
