Embodiment Construction

[0011] see figure 1 , an audio test cable 10 according to a preferred embodiment of the present invention is used to perform an audio test on a computer motherboard 20 . In this embodiment, the computer main board 20 includes an input audio jack 22 to be tested, an output audio jack 24 to be tested, an input pin header 26 and an output pin header 28. Two types of audio input ports and audio output port. And in another implementation (see figure 2 ), another computer motherboard 30 includes the input audio jack 22 to be tested, the output audio jack 24 to be tested, an input pin-slot dual-purpose head 32 and an output pin-slot dual-purpose head 34.

[0012] The input audio jack 22 to be tested and the output audio jack 24 to be tested are both 3.5mm audio jacks, and a left channel positive terminal and a right audio channel connected to the audio processing chip of the computer main board 20 are all extended in the inside. One positive terminal and two ground terminals (not...

Abstract

The present invention provides an audio test cable. The cable comprises an audio jack connecter and a plurality of types of audio input ports and audio output ports. The plurality of audio input ports and audio output ports are shorted and connected to the audio jack connecter, so the audio test cable can match with the plurality of types of audio input ports and audio output ports of a computer mainboard. Because the audio input ports and audio output ports are shorted to form a loop, a loopback test can be performed directly; and an acoustics test can be performed by inserting a speaker into the audio jack connecter. It is convenient for the test.

Description

technical field [0001] The invention relates to an audio testing line. Background technique [0002] A computer motherboard is generally provided with an audio input port for inputting audio signals and an audio output port for outputting audio signals. Currently, the main types of audio input ports and audio output ports are audio jack connector, header and jack and socket (JST). In order to ensure that the audio input port and the audio output port can work normally, the computer motherboard needs to conduct an audio test after the assembly is completed, mainly including a loopback (loopback) test and an actual sound quality test. The loopback test refers to short-circuiting the audio input port and the audio output port, and transmitting the audio signal to the audio input port through the audio output port, and analyzing whether the audio signal is lost, so as to judge whether the transmission function of the audio input port and the audio output port is normal. The ac...
