Abstract: A rotary earhanger structure of a wireless earphone includes an earhanger unit and a movable connection sleeve rotationally connected therewith. One end of the earhanger unit includes a first inclined surface portion extending obliquely in a preset rotational direction. The movable connection sleeve has a second inclined surface portion cooperatively connected with the first inclined surface portion. The movable connection sleeve is connected with an elastic member for driving the movable connection sleeve in a direction close to the earhanger unit. The external force rotates the earhanger unit in the preset rotating direction to adjust the wearing angle. When the earhanger unit is not subjected to the external force, the movable connection sleeve moves in the direction close to the earhanger unit under the force of the elastic member, so that the automatic reset function after the earhanger rotation is realized, thereby simplifying user operation and improving user experience.

Abstract: An earphone includes a housing provided with an accommodating groove and an opening groove. The opening groove connects the accommodating groove and the outside of the housing. A first hole is formed in the groove bottom of the accommodating groove. The earphone further includes an ear hanger, wherein one end of the ear hanger is provided with a rotating part inserted into the accommodating groove through the opening groove. The rotating part is provided with a second hole, a rotating shaft passes through the second hole and inserted into the first hole. The housing and the rotating part are rotatably connected around the rotating shaft. The earphone can effectively solve the problem that the rotating shaft of an existing ear-hanging earphone is prone to radial deflection, and is beneficial to enhancing the use hand feeling of a user.

Abstract: A method for calibrating an optical sensor in a Bluetooth headset and a Bluetooth headset are provided. The Bluetooth headset includes an optical sensor and a command execution device, the Bluetooth headset is connected to a charging box which is adapted to the Bluetooth headset, and a command initiation device and a command transmission medium are arranged in the charging box. With the method, if the command initiation device is triggered, the command initiation device sends a calibration command to the command execution device via the command transmission medium; and the command execution device calibrates an optical sensor in response to the calibration command to obtain a calibration result, and stores the calibration result.

Abstract: An in-ear earphone includes a face shell for mounting an earphone cable and a bottom shell provided with an ear cap, and the face shell and the bottom shell are detachably fixed to each other. A loudspeaker and an air valve are arranged at the bottom shell, and the bottom shell is further provided with a sound transmission channel. One end of the sound transmission channel is in communication with an inner ear canal located at a side where the ear cap is located, and another end of the sound transmission channel is connected to a sealing plug formed by the air valve and the loudspeaker. One end of the air valve is connected to the sound transmission channel, and another end of the air valve is connected to an outer ear canal, to control the communication between the sound transmission channel and the outer ear canal.

Abstract: An earphone storage device includes a charging storage box. A top cover that can be closed is provided on the charging storage box. A storage tank and a cleaning device are provided in the charging storage box, and a charging assembly is provided at the bottom of the storage tank. The cleaning device includes a dust removal assembly, a disinfection assembly and a sterilization assembly. A rotating shaft and a rotating motor are rotatably provided at the center of the top cover. The rotating motor is connected with the rotating shaft, the rotating shaft is connected with a rotating disc, and the rotating disc is provided with three mounting grooves. The dust removal assembly, the disinfection assembly and the sterilization assembly are respectively fixed in the three mounting grooves. When the top cover is closed, the storage tank is located directly below a rotation track of the mounting groove.
