Abstract: An electronic device includes a circuit board, a protective assembly, and a protective film. The protective assembly providing a cavity is arranged on one side of the circuit board. The protective assembly includes a first protective unit and a second protective unit. A third through hole communicating with the cavity is defined in the first protective unit. A supporting surface is defined on the second protective unit facing the third through hole. A projection of the third through hole is overlapped with a projection of the supporting surface along the first direction. The protective film is coupled to the protective assembly and arranged in the cavity to divide the cavity into a first cavity and a second cavity. The above-mentioned electronic device resists deformation of the protective film by setting the second protective unit between the circuit board and the protective film.
