Abstract
The present application relates to the field of earbuds, and in particular, to an earbud and a method for implementing a wearing detection and a touch operation. The earbud includes at least two wearing sensors; each of the at least two wearing sensors comprises one or more capacitive sensing units, and a maximum detected capacitance value or a sum of detected capacitance values of the capacitive sensing units of each of the at least two wearing sensors is used as a maximum detection value of the wearing sensor; and the wearing sensors are arranged at different positions where a head of the earbud is in direct contact with skin tissues in the ear, and the earbud is determined to be in a worn state when the maximum detection value of each of the at least two wearing sensors is not smaller than a wearing threshold.
