Abstract

The invention relates to an adaptive processing method of an earphone with an ANC and the earphone with the ANC. The adaptive processing method comprises the following steps: acquiring an environmental noise signal collected by a feedforward microphone; employing a first gain configuration of the filter component; based on the acquired environmental noise signal, determining whether an environmental factor influencing the noise reduction experience of the user under the second gain configuration of the filter component exists or not; in the absence of environmental factors, employing the second gain configuration of the filter component or maintaining the first gain configuration of the filter component; in the presence of environmental factors, a third gain configuration of the filter component is employed. Therefore, the problems of high background noise, poor wind noise experience, easy howling and the like caused when the noise reduction effect is pursued are avoided, and it is ensured that a user can have good use experience in any scene.

Description

technical field [0001] The present disclosure relates to the technical field of earphones, and more specifically, to an adaptive processing method for an earphone equipped with ANC and an earphone equipped with ANC. Background technique [0002] For headphones with ANC function, due to the complex and changeable external environment, in order to pursue the ultimate user experience, it is necessary to adjust the ANC parameters adaptively according to the scene. Most of the current solutions choose fixed parameters. Considering various factors, it is inevitable that there will be some Trade-offs, but even if compromises are made, performance is lost, but under certain conditions, a satisfactory user experience cannot be obtained. [0003] The existing earphones with ANC function increase the system gain based on the pursuit of higher ANC performance, in order to obtain more noise reduction in a noisy environment. However, this approach will inevitably bring the risk of high b...
