The source reports that the enclosure will allow you to control audio sources and interact with apps associated with the connected device.

what is known

Headphone cases are usually miniature power banks used for charging. They do not perform any other function. However Apple probably wants to increase its usefulness by combining the cover with an interactive displaywill expand the possibilities of controlling wireless headphones.

The patent states that users need a headphone device that can control playback, change audio sources, audio output modes, and more. Additionally, the need for a device capable of transmitting data using haptic and/or display mechanisms is indicated.

• In one of the options, Apple Music is controlled through the safe. This lets you control audio playback, adjust volume, select songs, and interact with music in other ways without having to look at the case itself.
• In another version, the case responds to certain gestures such as tapping and waving.
• In one of the scenarios, Apple explains that zipping the case could even be a way to change the listening mode of the AirPods. It probably means noise reduction and transparency modes.

Apple suggests that the chassis may contain additional processors and memory modules for certain scenarios. For example, the cover’s touchscreen can provide access to iPhone apps such as Phone, Mail, Messages, Camera, Calendar, Weather, Maps, and more.

It is not clear how useful and practical this approach can be:

• The company actually wants to copy some of the capabilities that can be performed on a smartphone. What is removed from the pocket for the user – a smartphone or a case with a screen – will not make a big difference.
• Its value may increase if it allows the use of headphones without a phone. However, then it is necessary to create in memory or the ability to insert a memory card. This makes the case a complete mp3 player, and Apple already has an iPod.
• In addition, the screen will also cause the prices of headphones, which are not cheap, to increase.
