Title:
LOUDSPEAKER PARAMETER CONFIGURATION METHOD AND RELATED APPARATUS
Document Type and Number:
WIPO Patent Application WO/2022/227793
Kind Code:
A1
Abstract:
Provided in the present application are a loudspeaker parameter configuration method and a related apparatus. The method comprises: first, detecting an actual resonant frequency of a loudspeaker of an electronic device and an environment temperature of a space in which the electronic device is located; then, querying a preset mapping relationship set to determine a reference resonant frequency corresponding to the environment temperature, wherein the mapping relationship set comprises a correlation between an environment temperature, which is measured in advance under a preset air pressure condition, and the resonant frequency of the loudspeaker; and finally, configuring a target audio parameter according to the actual resonant frequency and the reference resonant frequency, wherein the target audio parameter is used for preventing a diaphragm displacement of the loudspeaker from exceeding a preset diaphragm displacement. An air pressure change in an environment can be simulated according to a change in the resonant frequency of a loudspeaker after the interference of an environment temperature factor is eliminated, and then an appropriate audio parameter is configured, so as to improve the performance utilization rate of the loudspeaker. The present application is suitable for various environments, and the hardware cost is saved.
