The present disclosure provides a charging case for an earphone, comprising a lower housing assembly, an upper housing assembly, a main control circuit board, a magnetic suction structure, and an upper housing magnet. A Hall sensor is provided within the lower housing assembly, and the Hall sensor is electrically connected to the main control circuit board. The magnetic suction structure is configured to place an earphone in a magnetic suction manner, and when the upper housing assembly is in an open state with respect to the lower housing assembly, the Hall sensor is in a first state under an action of a magnetic field of the magnetic suction structure, and when the upper housing assembly is in a closed state with respect to the lower housing assembly, the upper housing magnet causes the Hall sensor to switch to a second state different from the first state.
