Abstract

The present invention discloses a method and a device for detecting an earphone wearing state and an earphone. The method comprises the steps of: obtaining the type of an environment where an earphoneis located, wherein the type of the environment comprises a noise environment type and a non-noise environment type; when the earphone is in the non-noise environment type, playing preset sound signals by the earphone; obtaining feedforward sound pressure and feedback sound pressure of the earphone to determine a difference of the feedforward sound pressure and the feedback sound pressure, wherein the feedforward sound pressure is sound pressure of sound signals picked up by a feedforward microphone of the earphone, and the feedback sound pressure is sound pressure of the sound signals pickedup by a feedback microphone of the earphone; and according to the comparative result of the difference and a first threshold range corresponding to the type of the environment, determining whether the wearing of the earphone is qualified or not.

Description

technical field [0001] The present invention relates to the technical field of acoustics, and more specifically, to a method and device for detecting the wearing state of an earphone and an earphone. Background technique [0002] With the improvement of living standards, earphones have become an indispensable electronic device in people's daily life and work. For noise-cancelling headphones, in the process of using the headphones, the headphones convert electrical signals into acoustic signals, and can also perform active noise reduction processing on external noise. [0003] At present, when headphones perform active noise reduction, they are usually divided into three noise reduction methods: feedforward noise reduction, feedback noise reduction, and a combination of the two. Among them, the noise reduction effect and sound quality of the earphone using the feedback noise reduction method are related to the state of the user wearing the earphone. Specifically, when the u...
