Abstract: An earphone, an earphone control method and an earphone control device are provided. The earphone control method and the earphone control device are applied to an earphone arranged with an ultrasonic transceiver and an ultrasonic receiver. The method includes: controlling the ultrasonic transceiver to transmit a first ultrasonic signal while the earphone is being worn (S110); obtaining a first echo signal collected by the ultrasonic transceiver, determining whether there is an object within a preset range based on the first echo signal, and controlling, in a case that there is an object within the preset range (S120), the ultrasonic transceiver to transmit a second ultrasonic signal (S130); performing feature extraction and gesture identification based on a second echo signal collected by the ultrasonic transceiver and a third echo signal collected by the ultrasonic receiver to obtain an identification result (S140); and determining whether the identification result indicates a valid gesture based on a current operation mode of the earphone and preset gestures corresponding to the current operation mode, and controlling, in a case that the identification result indicates the valid gesture (S150), the earphone to perform an action based on an action instruction corresponding to the valid gesture (S160). According to the present disclosure, the earphone is controlled, improving the control sensitivity of the earphone and the user experience, and facilitating miniaturization of earphones.
