Audio testing method and system of mobile terminal

Abstract

The invention provides an audio testing method and system of a mobile terminal. According to the audio testing method, a principle computer controls an audio switching device to select at least one of three testing loops to carry out an audio test on the mobile terminal. According to a first testing loop, an audio signal starts from an audio instrument and passes through an artificial mouth, a built-in microphone of the mobile terminal and an audio output end of an external earphone and then returns to the audio instrument. According to a second testing loop, the audio signal starts from the audio instrument and passes through an audio input end of the external earphone, a built-in receiver of the mobile terminal and artificial ears and then returns to the audio instrument. According to a third testing loop, the audio signal starts from the audio instrument and passes through the audio input end of the external earphone, a built-in loudspeaker of the mobile terminal and the artificial ears and then returns to the audio instrument. According to the audio testing method and system of the mobile terminal, influence of manual operation factors on an audio testing result is eliminated, the risk that the audio signal sent by the artificial mouth is directly coupled by the artificial ears in a loop test is effectively reduced, accuracy and stability of the audio testing result are improved, debugging is convenient, and cost is low.

Description

technical field [0001] The present invention relates to the fields of acoustic technology and communication technology of mobile terminals, in particular to an audio testing method and testing system for mobile terminals. Background technique [0002] Audio test is an audio index test for mobile terminals such as mobile phones, landline phones and mobile phones. Its purpose is mainly to ensure the audio performance of mobile terminals during communication. At present, the audio test generally adopts the test method based on the full audio cycle of the mobile terminal, mainly including the following two solutions: [0003] Manually pronounce the MIC (Microphone, microphone), and then manually obtain the audio signals at the built-in receiver (Receiver) and speaker (Speaker) and conduct judgment and analysis, so as to judge whether the audio circuit of the mobile terminal and its components are qualified; [0004] The artificial mouth converts the audio electrical signal of t...

AI Technical Summary

Problems solved by technology

[0005] However, the above two audio testing schemes have corresponding defects

Although the operation of the first solution is relatively simple, due to the manual operation, it is greatly affected by the subjective factors of the operator, and it is impossible to judge whether the audio test of the mobile terminal is qualified on an objective and uniform standard, thus easily affecting the quality of the product. Even if the audio test is judged to be unqualified, it is impossible to accurately locate the cause of the audio loop failure

[0006] In the second solution, since the full loop of the audio is turned on during the test, part of the acoustic signal emitted by the artificial mouth will be directly coupled to the artificial ear without passing through the audio loop loop of the mobile terminal, which will inevitably affect the accuracy of the audio test. sex
