Abstract

The invention relates to a horn, in particular to an integrated minitype noise reduction horn. The integrated minitype noise reduction horn comprises a microphone, and a horn unit, the horn unit comprises a circular horn support, a circular magnetic path and a circular vibration film. A round hole is arranged at the center of the circular horn support and connected with the microphone in an embedded mode, and the centers of the microphone, the circular horn support, the circular magnetic path and the circular vibration film are arranged on the same axis. The horn unit and the microphone adopt an integrated design, space of a noise reduction unit can be effectively reduced, and thickness of a cavity of an ear shell can be reduced, and the direction of the microphone of picking up the noise reaches a best angle to enable the integrated minitype noise reduction horn to be good in noise reduction effect, and due to the characteristics and advantages of the integrated minitype noise reduction horn, the integrated minitype noise reduction horn can be applied to products like a head-wearing type noise reduction headset and the like.

Description

technical field [0001] The invention relates to a horn, in particular to an integrated miniature noise reduction horn. Background technique [0002] With the continuous improvement of living standards, listening to music has become a way for people to relieve their mood and reduce stress in their spare time. At the same time, with people's continuous pursuit of high-quality life, people also have higher requirements for the quality of earphones. The manufacturer starts from the combination of humanistic care and health concepts, in order to allow every user to listen to the pure sound of life in a noisy environment, and to protect hearing, and develops intelligent noise-cancelling headphones to meet the needs of consumers. . [0003] The speaker unit and microphone unit used in the noise-canceling earphones on the market are both designed separately. The space volume of the inner cavity of the earphone is too large, which is not easy to carry, and the directionality of the...
