As a patent attorney with an interest in technology and music, this patent granted last month to Apple caught my eye.
It seems that a future generation of AirPod might include two methods of transmitting music to listeners. The first is conventional sound waves into the listener's ear. The second generates vibrations in the listener's skull.
I guess that would make for a more immersive experience.
An apparatus for delivering audio signals to a user includes an air-conduction transducer and a bone-conduction transducer. The air-conduction transducer is configured to convert a component of the audio signals to air vibrations detectable by an ear of the user. The bone-conduction transducer is configured to convert another component of the audio signals to vibrations in a cranial bone of the user via direct contact with the user.
