Abstract

The invention discloses an audio test method for an earphone microphone and a speaker of a mobile terminal. The method comprises that an audio test device sends test audio signals to the mobile terminal by measuring earpieces; the mobile terminal receives the test audio signals through an earphone microphone interface and generates audio signals according to the test audio signals; the speaker of the mobile terminal plays the audio signals; and the audio test device receives the audio signals generated by the mobile terminal and tests an audio channel of the mobile terminal according to the audio signals and the test audio signals. The invention further discloses an audio test system for the earphone microphone and the speaker of the mobile terminal. By means of the audio test method and the system for the earphone microphone and the speaker of the mobile terminal, an input channel of the earphone microphone and an output channel of the speaker of the mobile terminal can be tested; and test time is short, and the test cost is low.

Description

technical field [0001] The invention relates to the technical field of audio testing, in particular to an audio testing system and audio testing method for earphone microphones and loudspeakers of mobile terminals. Background technique [0002] Nowadays, mobile terminals have become a necessity in people's daily life. In the mass production of modern mobile terminals, in order to ensure the audio performance of the product, audio testing is a necessary part of production testing. Among them, the main test purpose of the audio test in the mass production of mobile terminals is the manufacturing quality. Among them, the audio test includes testing the patch quality of the motherboard and testing the assembly quality of each component. [0003] Traditional mobile terminal mass production audio testing methods include the following four methods: [0004] (1) Artificial subjective test of terminal voice loopback. Simulate user access through terminal software. The disadvanta...
