An electronic device includes a front frame that includes a planar portion, a first sidewall, and a second sidewall opposite to the first sidewall, the first sidewall and the second sidewall protruding from the planar portion. A back cover is coupled to the front frame. A speaker is attached to the front frame adjacent to the second sidewall of the front frame. The front frame includes several spaced first hooking members arranged on the first sidewall and the back cover includes several spaced second hooking members respectively engaged with the corresponding first hooking members. The first hooking members are used for cooperatively causing a natural frequency of the first sidewall to be greater than a resonance frequency of the speaker, thereby reducing noises caused by resonant vibration of the first sidewall induced by the speaker.
