Abstract

The invention provides an audio performance test system and an audio performance test method. The audio performance test system comprises equipment to be tested, a test clamp and a test host machine, wherein the test clamp comprises a transfer plate and a main clamp test plate, the transfer plate is connected to the equipment to be tested through a probe, and is connected to the main clamp test plate through a winding displacement wire, the main clamp test plate comprises a data collecting card, the data collecting card is connected to the test host machine through a data connecting wire, the data collecting card generates audio test signals through being driven by the test host machine and outputs the audio test signals to the equipment to be tested through the transfer plate, the transfer plate transfers the audio signals generated by the equipment to be tested according to the audio test signals to the data collecting card, in addition, the data collecting card collects the audio signals generated by the equipment to be tested to obtain audio sampling data, and the test host machine calculates the audio performance indexes of the equipment to be tested according to the audio sampling data.

Description

technical field [0001] The invention relates to audio testing technology, in particular, to an audio performance testing system and method for electronic products. Background technique [0002] In order to meet consumers' demands for multimedia playback, general electronic products (such as mobile phones, tablet computers, MP3 / MP4 players, etc.) have audio functions. To ensure audio performance, electronic products need to be tested for audio performance before leaving the factory. The traditional audio performance testing method is to provide the audio output of electronic equipment to an oscilloscope, and testers can judge whether the audio performance of electronic equipment meets the standard by observing the displayed waveform of the oscilloscope. However, the above test method using an oscilloscope has low test efficiency and is difficult to meet the audio test requirements of mass production; question. Contents of the invention [0003] In order to solve the abov...
