In addition, the key opening may be an oval opening, or may be a rectangular opening, or may be an irregular opening, which is not limited in the embodiment of the present application. The key openings may be used to mount the key panel 2, and the key panel 2 may be located in the key openings. The first elastic element 31 may be a metal elastic conductive film, or may be a spring, or may also be another element having elastic deformation capability.
It should be noted that the first key assembly 3 may be used to control volume, and the second key assembly 4 may be used to control power; or, one of the two first key assemblies 3 may be used to control volume, the other first key assembly may be used to control power, and the second key assembly 4 may be used to control volume; alternatively, the first key assembly 3 and the second key assembly 4 can also be used to control other functions of the electronic device, and the like, which is not limited in this embodiment of the application.
For example, the first key assembly 3 may be used for volume control, implementing the function of a volume key; the second key assembly 4 can be used for POWER switch control to implement the function of a POWER key, i.e., a POWER key. The two first key assemblies 3 can be respectively used for controlling the volume.

In the related art, the volume key and the power key are usually designed separately, and at least two keys are required to satisfy the functions of volume control and power switch control.
