An automated audio testing system for mobile phone motherboards

Abstract

The invention discloses an automatic audio testing system for a mainboard of a mobile phone, which comprises a mobile phone board to be tested, an auxiliary mobile phone board and a PC. Connect with the mobile phone board to be tested and the auxiliary mobile phone board, and the PC controls the mobile phone board to be tested and the auxiliary mobile phone board to record and playback each other and transmit the recorded sound to the PC. An audio analysis module is provided, and the audio analysis module judges whether the recording and playback equipment of the mobile phone board to be tested is normal by analyzing and comparing the recorded sound. The technical scheme of the present invention completes the automatic testing of the audio frequency of the mainboard of the mobile phone through the mutual cooperation of the mainboard of the machine to be tested and the mainboard of the auxiliary machine. efficiency.

Description

technical field [0001] The invention belongs to the field of electronic testing, relates to a mobile phone main board test, in particular to a factory mobile phone main board test and an automatic audio testing system. Background technique [0002] At present, the audio test of the mobile phone motherboard in the factory is mainly measured manually. The method is to manually open the audio test software on the mobile phone to record and play the sound, and then judge the result by human ears. This manual test method is the most primitive test method, which is relatively labor-intensive, and the judgment standard is greatly affected by human factors. [0003] In addition, the patent application CN201020573476.1 discloses a simple bionic audio test device, which can perform audio tests on mobile phones and other equipment. This method interconnects the mobile phone motherboard with the PC through the middle isolation coupling loop to process the sound information, and finally ...

AI Technical Summary

Problems solved by technology

[0006] But the shortcoming of above-mentioned existing mobile phone motherboard test is to need to add the external equipment such as artificial ear, artificial mouth, and these equipments are generally more expensive; Or add some sound collection and analysis boards, the price of this boards is just more expensive

However, the mobile phone audio test automatic fixture device of patent application CN201210152861.2 needs a mechanical structure, and the installation of a mechanical structure will cause the test fixture to generate vibration noise, which will affect the accuracy of the test.
