Description

TECHNICAL FIELD The present application relates to the technical field of device waterproofing, and more particularly relates to an electronic device. BACKGROUND For some electronic devices, in order to make the internal structure layout compact, a lighting element and a sound-receiving element inside a housing are generally mounted on a same circuit board with relatively small spacing between them. Since the housing needs to be provided with a hole at a position of the sound-receiving element for receiving sound, water vapor is likely to enter an interior of the housing. The water vapor entering the interior may adhere to a light-transmitting cover plate through which light rays of the lighting element passes to form water mist. Once the water mist is formed, the light rays emitted by the lighting element will be diffusely reflected, thereby affecting the lighting effect.
