Electronic device and control method

An electronic device, comprising:

• a housing with an accommodating space, wherein the housing comprises a groove surrounding the accommodating space, and a first conductive layer and a second conductive layer are disposed on the housing and on a first sidewall and a second sidewall of the groove, respectively;
• and
• a bezel, wherein at least a part of the bezel is disposed in the groove, wherein the bezel is configured to rotate around an axial direction of the housing in the groove,
• wherein a first electrode and a second electrode are disposed on a bottom surface of the groove,
• wherein when the bezel is located at a first position of the groove, the first electrode and the second electrode are conductively connected, and when the bezel is located at a second position of the groove, the first electrode and the second electrode are conductively disconnected, and
• wherein the electronic device further comprises:
• an elastic member, disposed on the bottom surface and having a first end connected to the first electrode,
• wherein one end of the bezel facing toward the bottom surface of the groove is provided with a protruding portion;
• when the bezel is located at the first position, the protruding portion presses against the elastic member, and a second end of the elastic member is connected to the second electrode;
• and when the bezel is located at the second position, the protruding portion moves away from the elastic member, and the second end of the elastic member is separate from the second electrode.
