Sound is basically a vibration, so it is not surprising that some audio companies rely on this vibration to develop headphones that use bone conductivity to deliver audio to the listener. Such headphones aren't exactly common, but future AirPods could potentially use the technology.
According to a patent discovered by AppleInsider, Apple is apparently investigating the potential use of bone conduction that could find its way to AirPods in the future. Of course it's a different story whether they do it or not, but using bone conduction offers some advantages that could make it a good reason to develop such a product.
For starters, bone conduction works for everyone, including those who may be hearing impaired. Second, since it doesn't get exactly into your ear canals, users with bone conduction audio devices can pick up ambient sounds that can be useful when they're in public and need to be aware of traffic or having conversations. It may also be possible to use it under water.
We imagine that such a setup in conjunction with devices such as AR glasses could also significantly improve the functionality if users do not have to stay away from the outside world. However, since it is a patent, it is not clear whether it is an actual product. So maybe you have no hopes yet.
