Apple has patented technology using a mechanized dampers to protect smartphones from ingress of dust and moisture. The corresponding application was filed in the U.S. patent office.
The patent and trademark office on Thursday published an application from Apple titled “Electronic device with valves within the ports of hull”, which describes the technology of iPhone protection from water. According to the document, inside the acoustic modules of the smartphone will accommodate special mechanical shutters. They will be placed immediately before the technological holes of the gadget (speaker, microphone, etc) and be opened and closed to restrict access. Currently they are protected by fine mesh to prevent the ingress of foreign objects, which however does not protect the device from moisture and condensation.
As soon as the iPhone sensor detects the presence of liquid, the mechanical shutter will be fed with current, whereby it will block access to the internal components of the smartphone.
I must say that this is not the first Apple patent concerning the protection of the iPhone from moisture. Earlier this month the company registered a patent application entitled “Removal of water from the holes”. It describes the method of removing fluid from technological holes mobile devices using electrical discharges. The company proposes to grant hydrophobic properties to the elements of speakers and microphones carried out by changing the electric discharge. In case of ingress of moisture to the conductive elements will be applied to the discharge.
The timing of the implementation of patented technologies are not specified. But sources claim that the iPhone 7 will boast water and dust resistant body. Apple already uses in the iPhone 6s passive hydro, involves installation of a special gasket around the perimeter of the housing.
