Title:
WIRELESS EARPHONES AND WIRELESS EARPHONE SYSTEM
Document Type and Number:
WIPO Patent Application WO/2021/042942
Kind Code:
A1
Abstract:
The present application relates to the technical field of electronics, and provided therein are wireless earphones and a wireless earphone system, which can improve the accuracy of detecting whether the wireless earphones are taken out of or placed into a case. The wireless earphones comprise a processor and a magnetic sensor coupled with the processor; when the wireless earphones are stored within a storage cavity of an earphone case, a surrounding magnetic field is a first magnetic field, and the intensity of magnetic induction as detected by the magnetic sensor in the first magnetic field is within a first intensity range; and when the wireless earphones are outside of the storage cavity of the earphone case, a surrounding magnetic field is a second magnetic field, and the intensity of magnetic induction as detected by the magnetic sensor in the second magnetic field is within a second intensity range, wherein there is no intersection between the first intensity range and the second intensity range. The magnetic sensor is used to detect the intensity of magnetic induction of a magnetic field surrounding the wireless earphones; and the processor is used to determine that the wireless earphones are taken out of the case when the intensity of magnetic induction as detected by the magnetic sensor switches from the first intensity range to the second intensity range, and determine that the wireless earphones are placed into the case when the intensity of magnetic induction as detected by the magnetic sensor switches from the second intensity range to the first intensity range.
