Problems solved by technology

Therefore, as long as the operator judges that the speaker emits the specified sound, it means that the left / right channel and the microphone function have been tested. This effectively simplifies the test steps and avoids the problems that existing operators are likely to miss or confuse.

Abstract

The invention discloses a test method of a sound socket of a portable electronic device. The sound socket is provided with a first sound track, a second sound track and a microphone. The test method includes that the portable electronic device controls the first sound track to play an appointed sound file; when the first sound track plays the appointed sound file, the portable electronic device synchronously records the sound played by the portable electronic device through the microphone to form another sound file; the portable electronic device plays the another sound file through the second sound track; and whether the another displayed sound file is meshed with the appointed sound file is judged, and functions of the first sound track, the second sound track and the microphone are normal if the another displayed sound file is meshed with the appointed sound file.

Description

technical field [0001] The present invention relates to a testing method for an audio jack of a portable electronic device, and in particular relates to a testing method for an audio jack of a portable electronic device which can simplify the testing procedure. Background technique [0002] Please refer to figure 1 , which is a structural schematic diagram of an external sound socket cable (Cable) of an existing tablet computer. Such as figure 1 As shown, the current external audio socket cable 100 of a tablet computer generally includes a design of four lines, namely, the left audio channel Left, the right audio channel Right, the microphone MIC, and the ground GND. During the FA machine test, it must be tested by the operator actually inserting the earphone microphone. There are roughly two types of testing methods: [0003] (1) First test the left (or right) channel, then test the right (or left) channel, then use the microphone (MIC) to record, and finally play the r...
