Title:
ADAPTIVE ADJUSTMENT METHOD AND DEVICE FOR ANC PARAMETER, AND STORAGE MEDIUM
Document Type and Number:
WIPO Patent Application WO/2023/159716
Kind Code:
A1
Abstract:
The present application belongs to the technical field of active noise cancellation (ANC). Disclosed are an adaptive adjustment method and device for an ANC parameter, and a storage medium. The method comprises: acquiring frequencies at which noise cancellation earphones have energy loss, and respective energy loss values at the frequencies, and determining the number of frequencies at which the energy loss value is greater than a first energy loss threshold value among the frequencies; determining whether the sum of the energy loss values is greater than a second energy loss threshold value, and determining whether the number of frequencies is greater than a preset threshold number of frequencies; and if the number of frequencies is greater than the preset threshold number of frequencies, calculating a clock rate of a chip of the noise cancellation earphones, and adjusting the chip to a target clock rate mode corresponding to the clock rate, and calculating and adjusting an ANC parameter in the target clock rate mode. By means of the present application, energy loss values at frequencies are obtained during fitness detection of earphones, different ANC parameter adjustment methods are used according to the energy loss values, and a CPU clock rate is dynamically adjusted according to different methods, such that the noise cancellation performance is ensured, the power consumption can also be reduced, complex usage scenarios of a user are satisfied, and the user obtains a relatively ideal noise cancellation effect.
