What you need to know
An Apple patent could reveal how future AirPods may use pressure detection to sense when they are in your ear
It would improve the accuracy of the current methods, which use optical sensors and accelerometers.
Current tech is useful, but can often result in false positives.
A newly published Apple patent has revealed how future AirPods may use an air pressure sensor to indicate whether or not they are being used.
As reported by AppleInsider, the patent is titled 'Acoustic in ear detection for a hearable device' and the abstract states:
A method for determining a current usage state of an earphone that includes a speaker and an air pressure sensor. The method obtains a pressure signal from the air pressure sensor that indicates air pressure proximate to the earphone, the air pressure sensor produces the pressure signal in response to the earphone being inserted into an ear of a user. The method processes...
