Bureau of patents and trademarks U.S. published patent application Apple, which describes a new technology to protect portable devices from moisture. The patented method involves the removal of liquids from technological holes iPhone and iPad with the help of electric charges.

The patent is called “the Removal of liquids from the holes” (expulsion of Liquid from an orifice). It describes the method by which you can get rid of water or any other fluids from the various cavities of mobile devices. The idea is to confer hydrophobic properties of the elements within the speaker holes (speakers or microphones) by changing the held electric charge.

To date, Apple equips such cavity fine mesh that prevents foreign objects and moisture. However, water may enter provided that the pressure of water or immersion of the gadget in depth. In addition, there may accumulate condensate depending on the humidity or temperature changes, which is bad for sensitive electronics components.

In some embodiments, the implementation of this technology are assumed to be options of placement of the sensors the presence of moisture inside of the acoustic modules. If using any other method means the analysis of tone of sound and the impact impulses.

If it is determined that the liquid was in the acoustic module, by conducting electricity to the elements is applied a charge. Components configured to fit the shape of the acoustic resonator. Apple notes that the conductive elements are covered with a protective layer of a dielectric material.

The application of the charge at different points will facilitate the withdrawal of the accumulated moisture to the hole in the housing. The process can speed up separate electricity conducting surface used as a protective grid.

Finally, this technology of Apple provides the opportunity to get rid of moisture inside your iPhone using acoustic waves and pulses propagating through acoustic channels and eject liquid.

It is unknown whether Apple plans to implement the technology in the near future, but in current products, the company has implemented passive measures of waterproofing. So, the iPhone 6s is equipped with a silicone gasket around the perimeter of the housing, and the Apple Watch boasts the presence of dust and water protection complying with the standard IPX7.

The latest rumors suggest that Apple does not exclude the possibility of producing a waterproof iPhone. The application for this patent was filed by the company in may 2014.
