an electronic device

Abstract

The invention discloses an electronic device comprising a shell, a first acoustic element which is positioned inside of the shell, and a first dustproof mesh. The shell is provided with a mouthpiece. A first vocal track cavity is formed between the mouthpiece and the first acoustic element. The first dustproof mesh is positioned on one side, which is close to the mouthpiece, of the inner part of the first vocal track cavity, and is used for reducing an amount of a dust coming into the first vocal track cavity from the mouthpiece. The amount of the dust coming into the first vocal track cavity from the mouthpiece is effectively reduced so that a cleaning process is convenient. Preferably, the electronic device also comprises a dustproof mesh bracket which is positioned inside of the first vocal track cavity. The dustproof mesh bracket is provided with a vocal track which is communicated with the mouthpiece and the first acoustic element so that audio information is enabled to enter from the mouthpiece and pass through a designable vocal track and be transmitted to the first acoustic element. Therefore, a sound guide structure is further optimized and a reliable guarantee is provided for obtaining a relatively plain and smooth frequency response curve.

Description

Technical field [0001] The invention relates to the field of electronic technology, in particular to an electronic device. Background technique [0002] With the development of science and technology and the gradual increase in application requirements, many types of electronic products use microphones to realize the sound reception function, receiving vibrations in a specific band frequency caused by vibrating air for sound transmission, recording and other purposes. For example, mobile phones, laptops and tablets. [0003] The sound receiving structure of the microphone of the above electronic product is roughly the same. The sound enters the sound channel in the casing from the speaking hole, and reaches the Mic acoustic element through the sound channel. After a long time of use, dust can easily enter the soundtrack and cannot be cleaned up, which greatly affects the sound quality of the sound, and also causes the trouble of bacterial growth. [0004] Take the basic structure o...

However, there is the possibility of dust accumulation in the sound channel cavity 20 outside the dustproof net 10, such as figure 2 Schematic diagram of dust accumulation shown

In particular, limited by the overall structure of the whole machine, the speaking hole 30 is usually located on the near edge side of the casing, and there is a predetermined distance between it and the acoustic element 30, and the sound hole 30 formed between the two is relatively perpendicular to the speaking direction. Channel cavity 20, the dust accumulated in the channel is difficult to clean. Obviously, in the long run, the entire channel will be blocked by dust, which will affect the sound collection effect of the microphone

[0006] In view of this, it is urgent to optimize the design of the microphone dust-proof technology for existing electronic equipment, so as to effectively avoid the defect of dust accumulation in the inner cavity of the sound channel
