Abstract

The invention discloses a casing assembly and an electronic device. The casing assembly comprises a middle frame and a dustproof assembly, wherein the middle frame has an outer surface, the middle frame is used for setting a microphone and is internally provided with a tone guide channel, the tone guide channel comprises a first end and a second end opposite to the first end, the first end penetrates through the outer surface, the tone guide channel continuously extends from the outer surface to an inner portion of the middle frame, the second end is formed in the middle frame, the microphoneis opposite to the second end, and the dustproof assembly is arranged in the tone guide channel and is between the first end and the second end. The dustproof assembly is arranged in the continuously-extended tone guide channel, dusts can be isolated from the middle frame or the portion of the tone guide channel adjacent to the outer surface of the middle frame, and the dusts are prevented from entering the middle frame and causing damage to components to affect the use effect. As continuous extension of the tone guide channel, additionally setting a casing for fixing a dustproof net is not needed, and the middle frame is made to have the possibility of being exposed directly as a mounting part.

Description

technical field [0001] The present application relates to the technical field of electronic equipment, and more specifically, to a casing assembly and electronic equipment. Background technique [0002] Electronic devices, such as electronic devices such as mobile terminals, have become one of the most commonly used consumer electronic products in people's daily life. Most of these mobile terminals are provided with components or structures such as microphones and microphone sound receiving holes. During daily use, dust will fall into the microphone sound receiving holes, causing blockage and affecting the quality of sound reception. Contents of the invention [0003] In view of the above problems, the present application proposes a casing assembly and an electronic device to ensure the dustproof effect of the mobile terminal. [0004] In a first aspect, an embodiment of the present application provides a casing assembly, including a middle frame and a dustproof assembly....
