Proximity sensor, also known as distance sensor, is a sensor that can detect the presence of nearby objects without contact, and is used in many fields. For TWS headphones, the proximity sensor needs to meet the market demand for high precision while meeting miniaturization. TWS earphones use proximity sensors, which are mainly used to detect whether the earphones are worn normally, so its detection distance is very close, and the requirements for accuracy are also very high. This demand also differentiates the proximity sensor in TWS headsets into two main functions.
Using proximity sensors to achieve in-ear/out-of-ear detection of wireless earphones helps extend the battery life of the earphones after a single charge
