A cover unit that is provided to an electronic device as a waterproof cover, the cover unit covering one or more openings formed in a housing of the electronic device with respect to a plurality of speakers, and comprising a frame member having a plurality of windows disposed therein, the windows facing the speakers in one-to-one correspondence, and a waterproof film covering the windows. Having such a structure, the cover unit covers the one or more openings formed in the housing, and has an advantageous effect of suppressing at least one of (i) an increase in parts composing an electronic device and (ii) an increase in distortion of sound. Additionally, since a vibration unit faces a corresponding one of the speakers, the unnecessary vibration of the vibration unit is inhibited, which leads to a reduction in the distortion of sound.
