Abstract

The invention provides a loudspeaker parameter configuration method and a related device, and the method comprises the steps: firstly, detecting the actual resonant frequency of a loudspeaker of electronic equipment and the environment temperature of a space where the electronic equipment is located; then, inquiring a preset mapping relation set to determine the reference resonant frequency corresponding to the environment temperature, wherein the mapping relation set comprises the corresponding relation between the environment temperature measured under the preset air pressure condition in advance 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 enabling the diaphragm displacement of the loudspeaker not to exceed a preset diaphragm displacement. The method can simulate the air pressure change of the environment according to the change of the resonant frequency of the loudspeaker after eliminating the interference of the environment temperature factor, further configures proper audio parameters, increases the performance utilization rate of the loudspeaker, is suitable for various environments, and saves the hardware cost.

Description

technical field

[0001] The present application relates to the technical field of electronic equipment, in particular to a loudspeaker parameter configuration method and related devices. Background technique

[0002] At present, electronic devices are generally equipped with loudspeakers (ie horns), and the structure of the loudspeakers generally includes a front chamber, a rear chamber, a diaphragm and a front chamber pipe. When the speaker is working, the vibration of the diaphragm is controlled by the electrical signal, so as to emit sound. In order to ensure the continuous safe and stable sound signal provided by the speaker, there will be no abnormal phenomena such as noise and broken sound, it is necessary to prevent the displacement of the diaphragm from exceeding the preset diaphragm displacement, and the preset diaphragm displacement of the diaphragm is affected by the resonant frequency of the speaker , the existing protection measures are to establish a reference ...
