The electronic device and the control method provided by the embodiments of the present application will be described in detail below through specific embodiments and application scenarios with reference to the accompanying drawings.

Please refer to FIG. 1 , an embodiment of the present application provides an electronic device, which includes: a deformation coil 100, a heating module 200, a controller 300, a switch module 400 and at least two functional modules;

At least part of the deformation coil 100 is formed by winding memory metal strips, and the heating module 200 is arranged adjacent to the deformation coil 100 to heat the deformation coil 100;

The deformation coil 100 is connected to the at least two functional modules through the switch module 400, and the heating module 200 and the switch module 400 are respectively electrically connected to the controller 300;

Wherein, the deformation coil 100 has at least two working temperatures corresponding to the at least two functional modules, and one working temperature corresponds to one functional module.

Since at least part of the deformation coil 100 is formed by winding memory metal strips, when the temperature of the deformation coil 100 changes, the shape of the deformation coil 100 will change accordingly. Correspondingly, as the shape of the deformation coil 100 changes, The inductance value of the deformation coil 100 will also change accordingly. Wherein, the morphological change of the deformable coil 100 may specifically refer to: please refer to FIG. 9 , under normal conditions, the arrangement of the coils of the deformable coil 100 is relatively loose, and the whole is in an “outwardly expanding state”, please refer to FIG. 10. When the deformation coil 100 is heated, the distance between the turns of the deformation coil 100 decreases, and at the same time, the deformation coil 100 shrinks inwardly, that is, the diameter of each turn of the deformation coil 100 decreases. When the heating of the deformation coil 100 is stopped and the temperature of the deformation coil 100 returns to the normal state, the shape of the deformation coil 100 can return to the above normal state.
