    摘要： Disclosed are a self-adaptive adjustment method of active noise cancellation (ANC) parameter, a device and a computer-readable storage medium. The method includes: obtaining frequency points of noise reduction headphone with energy loss and energy loss values of each frequency point, and determining a quantity of the frequency points with the energy loss values are greater than a first energy loss threshold; determining whether a sum of the energy loss values is greater than a second energy loss threshold, and determining whether the quantity of frequency points is greater than a preset frequency point quantity threshold.

    摘要： A wearable device is provided and includes a plurality of speakers including a first speaker, a second speaker, and an Nth speaker, a plurality of digital to analog converter (DAC)s including a first DAC connected to the first speaker, a second DAC connected to the second speaker, and an Nth DAC connected to the Nth speaker, an audio signal processing module including N DAC output paths configured to filter an audio signal according to each frequency band and output the audio signal, a memory; and a processor electrically connected to the plurality of DACs, the audio signal processing module, and the memory, wherein the memory includes instructions causing the processor to, when the audio signal is reproduced, analyze a frequency component included in the audio signal, activate the N DAC output paths when the frequency component included in the audio signal has a full band range, activate only a DAC output path for processing a specific frequency band among the N DAC output paths when the frequency component included in the audio signal has only the specific frequency band, and output the audio signal through a speaker connected to the activated DAC output path.

    摘要： A noise cancellation signal generation device includes a reference sensor; a speaker that outputs sound based on a noise cancellation signal a memory that records second information for obtaining a filter coefficient of a noise cancellation filter calculated on the basis of first information obtained in consideration of a change in a relative position between the speaker and a noise cancellation point and a noise cancellation processor that acquires the second information from the memory using a signal acquired by a sensor, and generates the noise cancellation signal on the basis of the filter coefficient obtained from the acquired second information and a reference signal acquired by the reference sensor.
