With the release of the iPhone 7 and iPhone 7 Plus in the list of important options for the new Apple smartphones, not the last place is occupied by “breathtaking surround sound.” However, its implementation is misleading to users who mistake two pairs of decorative grilles at the bottom of the case for a stereo system. But in fact, stereo is not there.
Since 2016, the iPhone said goodbye to the audio jack for headphones – this is a fact. Instead of the previous round hole, the lower edge is decorated with two gratings. It is logical to assume that the speakers are hidden there, with the help of which the stereo effect is created when the speaker system of the smartphone is working. Alas, this is self-deception – if we look at the specification on the official Apple website, we find that behind one (on the left side of the Lightning connector) of decorative grilles there is only a microphone. And behind the second (on the right side) is the only end speaker and an additional microphone.

The stereo sound in the iPhone 11, 11 Pro, XS, XR, X, 8 and iPhone 7 is created using the speaker located next to the ear, which is located at the top of the apparatus.
When you talk on the phone, only one of the acoustic waves is transmitted to your ear, and if you turn on the music at full volume, both devices will start working. Twice as much energy – twice as loud the sound, which is noticeable when using the speakerphone. Plus, Apple hints that the latest iPhone has “increased dynamic range” compared to older models.

And why then the symmetrical grille at the bottom of the iPhone 11, 11 Pro, XS, XR, X, 8 and iPhone 7?
For the sake of beauty, literally. More precisely, for the microphone to work properly, perforation was vital, so the designers simply added the same pattern on the other hand, for symmetry. And lumps of dust will probably accumulate there.
It should be noted that with the release of the iPhone XS, the grilles at the end became asymmetrical.
