Abstract

The invention relates to the field of earphones, and particularly relates to an anti-noise earphone. The anti-noise earphone provided by the invention comprises a shell, an ear plug, a loudspeaker unit, a first microphone and a second microphone. The shell comprises a sound tube and a cavity; the sound tube has a first end and a second end, which are opposite to each other; the first end of the sound tube is provided with a sound outlet, and the cavity is connected to the second end of the sound tube; the ear plug is sleeved on the sound tube, and the ear plug has an accommodating space for accommodating the sound tube; the loudspeaker unit and the first microphone are disposed in the sound tube and are located in the accommodating space of the ear plug; and the second microphone is disposed in the cavity. By adoption of the configuration mode, the noise can be collected more comprehensively, and the miniaturization requirements of the earphone can be met.

Description

technical field [0001] The invention relates to an earphone, in particular to an anti-noise earphone. Background technique [0002] With the continuous advancement of science and technology, all electronic products are developing towards the trend of lightweight and miniaturization. People can use miniaturized electronic products anytime and anywhere, such as radios, walkmans or smart phones. Regardless of the above-mentioned electronic products, in order to allow users to listen to the sound information provided by the electronic product without disturbing others, earphones have become a necessary accessory for the electronic product. [0003] When general earphones are worn, noise tends to leak through the gap between the earplugs and the ear canal and cause disturbance to the user. Anti-noise earphones in the prior art include active anti-noise earphones and passive anti-noise earphones. Most passive anti-noise headphones use mechanical noise reduction, but their anti...
