Audio test system and audio test method for to-be-tested device

Abstract

The invention discloses an audio test system and an audio test method for a to-be-tested device. The audio test method for the to-be-tested device comprises that: a test audio is sent through a sound-sending end of the to-be-tested device, the to-be-tested device is controlled to conduct sound recording through a sound-receiving end by a control device to produce a to-be-tested audio, the to-be-tested device is controlled to broadcast the to-be-tested audio from one of two side sound-sending ends by the control device after the sound recording is finished so as to conduct the sound recording through the a test sound-receiving end, an audio analysis program is called to produce a first test result, the to-be-tested audio is broadcasted from the other of the two side sound-making ends so as to conduct the sound recording through the test sound-receiving end, and the audio analysis program is called to produce a second test result. Therefore, the audio test method for the to-be-tested device can be used for executing an automatic test to eliminate complex testing steps and details.

Description

technical field [0001] The invention relates to a testing technology, in particular to an audio testing system and an audio testing method of a device under test. Background technique [0002] For manufacturers, how to detect the sound quality of portable electronic devices (such as notebook computers, mobile phones, tablet computers, etc.) on the production line has always been an important issue. In order to ensure the audio quality of their products, manufacturers will conduct various tests on the audio circuits of their products. These tests include measuring the frequency response and total harmonic distortion (total harmonic distortion+noise) of the audio circuits. , referred to as THD+N), signal to noise ratio (signal to noise ratio), two-channel volume balance (2 channel ratio), crosstalk (crosstalk), output waveform (waveform), etc., and use the above-mentioned tests to test The audio characteristics of its products. [0003] However, with the existing technology,...

AI Technical Summary

Problems solved by technology

[0003] However, with existing technologies, manufacturers need to purchase many complex and expensive instruments to test the sound quality of audio playback devices

This will not only increase the manufacturing cost, but also the operation process is complicated and time-consuming, which is not suitable for execution on the production line

As far as the current audio detection method is concerned, since part of the detection content needs to be judged by the human ear of the detection personnel, and the noise on the production line is noisy, it often disturbs other detection personnel nearby

Therefore, there is no uniform standard in the way of distinguishing audio by the human ear, and it is easy to produce considerable errors, and it is difficult to avoid the misjudgment of the test personnel.
