With the launch of the new iPhone 7, lots of Apple fans are delighted and annoyed at the same time. The reason behind this annoyance? Simply the removal of its headphone jack. Apple CEO Tim Cook has already explained why they decided to remove the 3.5mm headphone jack from the newly launched iPhones– “that jack takes up a lot of space in the phone, a lot of space. And there’s a lot of more important things we can provide for the consumer than that jack.” So, what’s the more important thing Apple actually housed in the place of the jack? A piece of plastic called a barometric vent.
A teardown of iPhone 7 by the gadget repair community iFixit showed that the “extra space” after it got rid of the headphone jack is actually filled with a piece of plastic, sitting behind the ingress protection (waterproofing).
That space helps iPhone’s barometer function properly, as the company explained it to The Verge.
A Barometric Vent
“According to Apple it’s a “barometric vent. Apparently adding all the waterproofing to the iPhone 7 and 7 Plus meant that it was more of a sealed box, and so to be able to have an accurate and working barometer, Apple used that space. The barometer is the thing that allows a phone to measure altitude, and Apple points out that on the iPhone 7 it can measure even minor changes like climbing a flight of stairs.”
According to the iFixit team, it is “a component that seems to channel sound from outside the phone into the microphone… or from the Taptic Engine out.” The teardown also showed that Apple has used a lot of adhesives to hold the phone together, thanks to iFixit as they not only ripped apart the brand new iPhone 7, but also they did X-rays to show us inside that Taptic Engine black box. It has raised a concern about whether the phone will be waterproof again if anyone gets anything replaced or repaired in the phone.
