AirPods are famous, first and foremost, for the ease of use they offer users. And it is that few headphones are going to find that we can pair and use so easily with our devices. Nevertheless, To deliver these results Apple has to work hard and patent systems like the one we see below. Yesterday we learned that the Cupertino company has been working on AirPods no less than since 2015, the time to which this patent dates back to slightly showing us how the AirPods pairing system works that makes them so special.
As we could imagine, the AirPods box has its own processor, memory and a communications interface that we imagine is based on Bluetooth and NFC technology completely, that is the reason why the AirPods are fully compatible with any device with Bluetooth technology, not with NFC technology, we already know that Apple has this quite restricted system.
The button that includes the AirPods box allows the headphones to automatically pair with any device connected to iCloud that has the same Apple ID. In the case of pairing with non-Apple devices, it will be necessary to enter a PIN to verify the security of the connection.
Each of the headphones has a memory module for Bluetooth information as well as its own MAC address, which makes them independent Bluetooth devices.
In the patent graphic we can also see how Apple determines one of the AirPods as the primary, which communicates with the other AirPod as a link. In this way, the secondary receives the audio signals directly from the first earphone. Thanks to this latest patent we have been able to know a little more about what AirPods are, although we certainly imagined it.
