Problems solved by technology

[0002] When the existing manufacturers of sound playback products test the playback function of the machine, they usually connect the signal lines of each port first, then play 748CD or MP3 signals, output from the speaker line of the machine to the oscilloscope, and adjust the CD by watching the waveform readings. Or MP3 tracks modify the frequency and amplitude of the audio source to test the audio playback performance, so the test takes too long, the efficiency is low, and the test results cannot be expressed and recorded in the form of data
In addition, in the existing detection process, the port signal line is connected to the product by manual wiring, which takes a long time, reduces production efficiency, and increases production costs.

Abstract

The invention provides an automatic audio test system which comprises a computer, a control panel, a plug wire jig, an audio channel switcher and an audio analyzer. The computer is electrically connected with the control panel, the audio channel switcher and the audio analyzer. The control panel, the plug wire jig, the audio channel switcher and the audio analyzer are electrically connected in sequence. The plug wire jig comprises a bearing platform, a driving device and a metal plate which is provided with a port signal line plug, wherein the driving device and the metal plate are arranged on the bearing platform. The driving device and the metal plate are fixedly connected. Datamation of testing results and automation of test processes are achieved, test time is short, production efficiency is high and production cost is reduced.

Description

technical field [0001] The invention relates to the field of audio testing, in particular to an audio automatic testing system. Background technique [0002] When the existing manufacturers of sound playback products test the playback function of the machine, they usually connect the signal lines of each port first, then play 748CD or MP3 signals, output from the speaker line of the machine to the oscilloscope, and adjust the CD by watching the waveform readings. Or the track of MP3 modifies the frequency and amplitude of the sound source to test the audio playback performance, so the test takes too long, the efficiency is low, and the result of the test cannot be expressed and recorded in the form of data. In addition, in the existing detection process, the port signal line is connected to the product by manual wiring, which takes a long time, reduces production efficiency, and increases production cost. [0003] Therefore, it is necessary to develop an audio testing syste...
