This is how Apple will waterproof its future iPhones

Apple filed an application to US Patent and Trademark Office with regards to the same

Recently, we reported that Apple plans to make some major hardware advances with its upcoming smartphones. And one of the many upgrade would be waterproofing its future iPhones. However, not much was known with regards to how Apple plans to do the same.

On Thursday, the US Patent and Trademark Office published a report by Apple, titled "Electronic devices with housing port shutters", which explains the physics Apple plans to use to bring the feature to effect in its smartphones.

(The figure above describes the places of the electronically controlled shutters)

The application sketches a system of electrically controlled shutters, placed over the openings of critical components like speaker boxes and microphones. At the command of an onboard logic, these shutter mechanisms can quickly block, thereby preventing intrusion of contaminants into the interior portion of the housing.
