Abstract

The invention relates to the technical field of an earphone, especially to a head-mounted noise-cancelling headphone comprising an active noise reduction capsule arranged inside a case of the head-mounted noise-cancelling headphone. The active noise reduction capsule includes a housing having a front shell and a rear shell; and the front shell and the rear shell are buckled mutually to form a sealed cavity. Besides, the active noise reduction capsule also includes a loudspeaker, a microphone, and a damping fin; the loudspeaker assembled at the back of the front shell is arranged inside the sealed cavity; the microphone installed at the front side of the front shell is arranged outside the sealed cavity; and the damping fin installed on the rear shell is used for adjusting an audio curve and the tone quality. The invention aims at providing a head-mounted noise-cancelling headphone, so that a technical problem that the noise cancelling effect of the existing noise-cancelling headphone is affected because of different sound cavities of the left ear and the right ear can be solved.

Description

technical field [0001] The invention relates to the technical field of earphones, in particular to a head-mounted noise reduction earphone. Background technique [0002] Noise-canceling headphones can not only reduce environmental noise and protect the hearing of users, but also allow people to listen to high-quality music and enhance the enjoyment experience. Therefore, now noise-cancelling headphones are more and more favored by consumers, and people have higher and higher requirements for the noise-cancelling effect of noise-cancelling headphones. [0003] At present, the speaker unit and microphone unit for noise-cancelling earphones on the market adopt a separate design, and the inner cavity of the earphone is also equipped with printed circuit boards, batteries, USB ports, sockets and other mechanisms. It is difficult to ensure that the left and right ears can have the same The sound cavity and the same airtightness make it difficult to ensure that the left and right ...
