Abstract: An electronic device including a first body, the first body being plate-shaped with a first side and a second side opposite the first side; a second body, the second body being plate-shaped, rotatably connected to the first body through a connecting device, with a third side and a fourth side opposite the third side; and a display device disposed on the first side, including a display unit set, the display device being configured to present an image, where the display unit set is configured to present three or more colors, and the image is perceived by a viewer after being illuminated by light.

Abstract: An electronic device includes: an outer case, at least a portion of the outer case being configured to maintain a positional relationship between the electronic device and a wearer's ear; a first sound generator and a second sound generator both provided inside the outer case; and a controller configured to control the first sound generator and the second sound generator to output sounds.

Abstract: An electronic device includes a first body; a second body having a first display device and capable of being physically connected to or separated from the first body, where if the second body is physically connected to the first body, the second body is rotatable relative to the first body; and a third body having a second display device and capable of being physically connected to or separated from the first body, where if the second body is physically connected to the first body, the second body is rotatable relative to the first body.

Abstract: A control method includes making, by a first interaction component, a wireless connection according to a connection rule in response to the first interaction component switching from a first state to a second state; and making, by a second interaction component, the wireless connection according to the connection rule in response to the second interaction component switching from the first state to the second state.
