Abstract: A handheld electronic device is provided, which includes a body and a key layout. The body has a base surface. The key layout is disposed on the base surface of the body and includes a plurality of keys. The key layout is a QWERTY key layout and the keys are adapted for users to press with their left or right thumb while holding the body in single hand or both hands. Each key has a curved surface protruded from the base surface and each curved surface has an inflection point. A distance between two inflection points of the curved surfaces of any two adjacent keys is greater than a distance between two figure centres of the orthogonal projections on the base surface of the curved surfaces of the two adjacent keys.

Abstract: A handheld electronic device including a first body, a second body, a stand, and a transmission module is provided. The second body is slidably connected to the first body. The stand is pivoted to the first body. The transmission module connects between the first body and the second body. When the second body slides relative to the first body, the second body drives the transmission module to move the stand so that the stand is opened and closed relative to the first body.

Abstract: An electronic device and a method for using the same are provided. The electronic device includes a first body, a torsion hinge, and a second body. The first body has a first magnetic component. The torsion hinge is slidably disposed on the first body. The second body is connected to the torsion hinge and has a second magnetic component. The second magnetic component magnetically attracts the first magnetic component when the torsion hinge is located at a first position, and enables the first body and the second body to be in a folded state. The second magnetic component separates from the first magnetic component, and the torsion hinge drives the second body to rotate relative to the first body when the torsion hinge leaves the first position, so as to enable the first body and the second body to be in an unfolded state.
