Automatic mobile phone main board audio testing system

Abstract

The invention discloses an automatic mobile phone main board audio testing system which comprises a mobile phone board to be tested, an auxiliary mobile phone board and a PC (personal computer). The mobile phone board to be tested and the auxiliary mobile phone board are respectively provided with a recording device and a playback device, the PC is respectively connected with the mobile phone board to be tested and the auxiliary mobile phone board and controls the mobile phone board to be tested and the auxiliary mobile phone board to mutually record and play back, recorded sound is transferred to the PC, and an audio analysis module is arranged in the PC and judges whether the recording device and the playback device are normal or not by analyzing and comparing the recorded sound. According to the technical scheme, the mobile phone board to be tested is matched with the auxiliary mobile phone board to automatically test audios of the mobile phone main board, the system is high in universality, simple, convenient and easy, the audios of the intelligent mobile phone main board are automatically tested, manpower cost is reduced, and testing efficiency is improved.

Description

Technical field [0001] The invention belongs to the field of electronic testing, and relates to a mobile phone motherboard test, in particular to a factory mobile phone motherboard test and an automated audio test system. Background technique [0002] At present, the factory's mobile phone motherboard audio test is mainly done manually. The method is to manually open the audio test software on the mobile phone to record and play, and then judge the result through the human ear. This manual testing method is one of the most primitive testing methods, which is more 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 that can perform audio testing of mobile phones and other equipment. This method is connected to the main board of the mobile phone and the PC through the isolation coupling loop in the middle to process the sound information and finally t...

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.
