Closed-loop automatic detection vibration reduction method and system, terminal and storage medium

Abstract

The invention discloses a closed-loop automatic detection vibration reduction method. The method comprises the following steps: controlling a loudspeaker of equipment to be detected to play a detection sound source; controlling a microphone of the to-be-tested device to record and collect an audio signal when a loudspeaker plays the detection sound source; analyzing the audio signal to obtain test analysis data; and suppressing the amplitude of the loudspeaker in the resonant frequency range according to the test analysis data. According to the closed-loop automatic detection vibration reduction method provided by the invention, the resources of the electronic equipment are fully utilized, closed-loop detection is realized, and the obtained audio signal is more real; meanwhile, the real resonance state of the equipment is determined according to the audio signals of the loudspeaker on the electronic equipment, then resonance noise is correspondingly suppressed according to different resonance frequency ranges of the electronic equipment, the resonance problem of the electronic equipment is solved in a targeted mode, and better sound listening experience is brought to a user.

Description

[Technical field] [0001] The present invention relates to the technical field of electronic devices, and more particularly to a closed loop automatic detection and damping method, system, terminal, and storage medium. 【Background technique】 [0002] With the maturation of Internet technology, multimedia functions of electronic devices (such as laptops) are widely concerned, users are getting higher and higher for music on video, games. At the same time, as users improve the sound quality requirements for multimedia equipment, the number of MIC (microphones) and speakers in laptops and increasing performance are increasing. However, the laptop is large, and the structure is complex, the horn is low frequency performance. When the speaker unit is driven by strong, while the electrical signal drives the diaphragm vibration, the housing, the keyboard and other structural keys can also generate common vibration, resulting in a larger resonance noise. [0003] At present, the commonly ...
