iPhone 7 is rumored to be a waterproof device and a recently published patent takes the speculations a step further.

An Apple patent application published Thursday by U.S. Patent & Trademark Office, titled, “Liquid Expulsion From An Orifice,” depicts a hi-tech way to dry out the iPhone in case it drops into any liquid. The patent reveals an invention wherein the electrical charges push out the liquid through the microphone and speakers. Another method listed involves a mesh on the speaker, preventing the water to enter the device.

In the first method the feature is activated when water is detected by pressure, optical or moisture sensors. The electrical charges then jump into action to push the water out. The second method, prevents the water from entering the device in the first place. The patent was filed in May 12, 2014, and credits Stephen P. Zadesky, Fletcher Rothkopf and Ashley E. Fletcher.

According to an earlier report, KGI analyst Ming-Chi Kuo had listed out a few iPhone 7 features and the device being waterproof wasn’t mentioned at all. So, while an iPhone squirting water seems to be a quality that the smartphone of the future may possess, it remains to be seen whether iPhone 7 will arrive with a waterproof casing.

Recently, Apple Insider got its hands on a copy of a research note by Kuo which  details the specs of the iPhone 7 and iPhone 7 Plus, both expected to arrive in the fall of next year. The smaller variant with a 4.7-inch screen may possess 2GB RAM, while the larger 5.5-inch model will have 3GB RAM onboard.

The devices are expected to come powered by a much faster and powerful A10 chip. The upcoming handsets are expected to have a revamped design and may just be the sleekest iPhones ever to be manufactured.

Apple fans can keep coming back for more updates on iPhone 7.
