Sound broadcasting mechanism and electronic device using the same

Abstract

A sound broadcasting mechanism and an electronic device using the same are provided. The sound broadcasting mechanism includes a sound box, a sound broadcasting element and a sound enhancing element. The sound broadcasting element is disposed at the surface of the sound box to generate a sound signal. The sound enhancing element is disposed at the surface of the sound box. The sound enhancing element includes a resonating film and a weight increasing element. The resonating film can resonate with the sound signal in a resonating frequency range to enhance the sound intensity of the sound signal in the resonating frequency range. The weight increasing element is attached to the surface of the resonating film. The weight of the weight increasing element is related to the resonating frequency range.
