Abstract

The invention provides a method and device for carrying out the fault diagnosis of the audio element of a mobile terminal. The device comprises a recording acquisition module which is used for using the built-in microphone of the mobile terminal to record sweep frequency audio so as to obtain a first recording when the speaker of the mobile terminal plays a sweep frequency audio in a set frequency range in an anechoic chamber and using the external microphone of the mobile terminal to record a frequency audio so as to obtain a second recording, a recording conversion module used for converting the first recording into a first frequency response curve and converting the second recording into a second frequency response curve, a fault diagnosis module used for comparing the first frequency response curve and the second frequency response curve with a set standard curve and carrying out fault diagnosis on the speaker and the microphones in the mobile terminal based on a comparison result. According to the method and the device, the analysis efficiency of an after-sale audio failure is improved.

Description

technical field [0001] The invention relates to the technical field of audio detection, in particular to a method and device for fault diagnosis of audio components of a mobile terminal. Background technique [0002] Faulty audio components in the mobile terminal will affect the user's audio experience. If the speaker of the mobile terminal fails, the sound quality of the hands-free receiver will deteriorate, and the sound quality of the music played will deteriorate. If the microphone of the mobile terminal breaks down, it will result in a poor voice transmission effect. At this stage, the audio performance test of the audio components in the mobile terminal is mainly performed by the RS audio automatic analyzer, so as to determine whether the speaker and the microphone in the mobile terminal are faulty. The RS audio automatic analyzer can also be used to adjust the channel parameters of the faulty speaker and microphone to repair the faulty speaker and microphone. Howeve...
