IEarly AirPods: Optical Sensors
Description of the optical sensors used in first-generation AirPods
The first-generation AirPods, introduced in 2016, made use of optical sensors as the primary technology for detecting whether the AirPods were in the user’s ear. These sensors were located in the stem of each AirPod and consisted of an infrared emitter and a receiver.
When the AirPod was placed in the ear, the proximity sensor detected the presence of the user’s earlobe by measuring the infrared light reflected back from the ear. This detection triggered the AirPods to turn on and connect to the user’s device.
How the sensors detect contact with the ear
The optical sensors in the early AirPods relied on the detection of light to determine when they were inserted into the ear. The presence of the earlobe obstructed the infrared light from reaching the receiver, indicating that the AirPods were in the user’s ear. When the AirPods were removed, the infrared light was able to reach the receiver, signaling that the AirPods were no longer in use.
Pros and cons of this technology
While the optical sensors used in the first-generation AirPods provided a basic level of ear detection, they had limitations. The reliance on detecting the presence or absence of the earlobe could sometimes result in inaccuracies, leading to false positives or false negatives. For example, if the AirPods were not inserted deeply into the ear, the sensors might not detect the earlobe and incorrectly assume that the AirPods were not in use. On the other hand, if the AirPods were placed near the earlobe without actually being inserted, the sensors might register a false positive and activate the audio playback.
Additionally, the optical sensor technology did not provide precise positioning information within the ear, such as whether the AirPods were properly seated or at risk of falling out. These shortcomings prompted Apple to develop and introduce more advanced sensing technologies in subsequent iterations of the AirPods.
Overall, the optical sensors in the first-generation AirPods laid the groundwork for the ear detection feature, but improvements were needed to enhance accuracy and user experience.
