Here’s Why There’s A Tiny Hole Next To Your iPhone Camera.


When the iPhone 5 was released, it came with a new tiny detail.

Buying an iPhone means you are treating yourself to a piece of technology where every single feature has been meticulously thought-out. Nothing in the handy smartphone is by chance. And just when you think you have figured out every nook and cranny in the phone, there is a small component most of us have not noticed.

When the iPhone 5 was introduced, a small but important element came with the newest release. It may seem irrelevant at first glance but a small hole at the top of the case on the back of the phone plays an important role.

Most users assume the tiny circle is a reset button. However, there is nothing to push and even if you touch it, nothing happens. If you love the sound quality you get from your cool phone, you can thank that tiny little addition because it's a microphone. But this mic is not there accidentally, it has a very specific function.

The hole is right in the middle, between the lens and the flash.


This is one of three microphones in the mobile.

Having more than one microphone allows for multi-directional audio coming from different directions.


By having three microphones, users get more coverage.

Regardless of the position users are in audio will be picked up.

An internal processor dissects the audio data.

What this means for the user is clear and crisp sounds


Unnecessary background noise gets eliminated.

The microphone in the back helps Siri understand accents, improve FaceTime, and conference calls.


Where are the other two microphones?

Aside from the back, middle button, the other two are located at the bottom of the phone and the front. The last one is under the grill with the phone speaker. This microphone is not active during a phone conversation.

The purpose of the bottom and top one is to give clearer sound.

The one in the back is used when someone is speaking.


Apple is working hard so your ear won't have to.

The earpiece in the iPhone not only does noise cancellation when you are speaking but also what you are hearing from the person you are speaking with.


The microphones take up 20% less space than its predecessor.

Yet the technology has advanced so far that it's hard to believe so much can be done with so little.

Wideband audio is a new technology.

Wideband audio or HD Voice allows for the sound spectrum to be the closest and truest human speech range.

Not all mobile phone carriers support wideband audio.

The person you are calling also has to have wideband audio for it to work. Otherwise it will just be a regular digital call.

So when Siri needs to talk to you, she is listening through the back button.

If you love talking on Snapchat, it's all thanks to the third microphone. Not a bad addition.


To get this sound quality, people were paying extra money for it.

High-end Bluetooth headsets use to be the only way people were able to have clear and sharp audio.

Let your inner recording artist come through.

You can record in surround sound. Imagine using to record someone playing your favourite song?
