Abstract
An earbud and a method for implementing a wearing detection and a touch operation are provided. The earbud includes: at least two capacitive wearing sensors arranged at different positions where a head of the earbud is in contact with skin tissues in an ear, and the earbud being determined whether to be in a worn state according to the detection values of the at least two capacitive wearing sensors; a capacitive touch sensor arranged on the head or a stem of the earbud away from the ear and being configured to detect a touch operation; and a detection processing circuit being configured to detect and process capacitance signals detected by the wearing sensors and touch sensor, and the wearing sensors and touch sensor being electrically connected with the detection processing circuit and sharing the detection processing circuit.
