Title:
EARPHONE STATE DETECTION METHOD AND APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/161305
Kind Code:
A1
Abstract:
Disclosed are an earphone state detection method and apparatus. The earphone state detection method is applied to earphones. The earphone comprises a housing, and a main board, a first capacitance sensor and a second capacitance sensor that are located in the housing. The main board is electrically connected to the first capacitance sensor and the second capacitance sensor, and the main board is provided with a grounding area. The first capacitance sensor is located between the housing and the second capacitance sensor; and the second capacitance sensor is located between the first capacitance sensor and the main board. The method comprises: acquiring a first capacitance value that is output by a first capacitance sensor and a second capacitance value that is output by a second capacitance sensor; and when the first capacitance value and the second capacitance value satisfy a preset condition, determining that an earphone is in a worn state.
