Problems solved by technology

However, in the existing technologies, most equalizers can only provide a fixed transfer function to compensate
In this way, when the music signal fed back changes, the equalizer cannot provide the corresponding sound effect

Abstract

The application provides an audio processing device and an audio processing method, wherein the audio processing device contains a reverse noise filter, an output circuit and an equalizer circuit, wherein the reverse noise filter is configured to process a digital signal to produce a noise canceling signal; the output circuit is configured to mix the noise canceling signal with an equalized signalto generate a mixed signal, and generate a sound output signal based on the mixed signal, wherein the digital signal is associated with the sound output signal; and the equalizer circuit is configured to receive an input signal, and adjust at least one parameter in the equalizer circuit according to the equalized signal and the digital signal to process the input signal as an equalized signal.

Description

technical field [0001] The present disclosure relates to an audio processing device, and in particular to an audio processing device and method for detecting the state of an earphone. Background technique [0002] In order to provide higher sound quality, active noise cancellation mechanisms are often added to headphones to reduce the impact of environmental noise. In some technologies, active noise cancellation mechanisms are implemented with feedback circuits. In these technologies, after the audio signal is output from the speaker, the audio signal is received by the internal microphone and fed back into the mixing device. In order to prevent the original audio from being affected by the feedback audio signal, an equalizer needs to be added to provide compensation. [0003] Generally speaking, the music signal fed back will be changed by external factors (such as the position of the earphone, the shape of the user's ear). However, in the prior art, most equalizers can ...
