Step S140: carry out from the audio frequency instrument through the audio input end of external earphone, the boombox of portable terminal and the audio-frequency test of the 3rd test loop that artitificial ear returns the audio frequency instrument.
After the audio-frequency test in second loop finishes, host computer 220 calls the 3rd instruction immediately, be positioned at a, the conducting of f interface relay of audio frequency switching device 210 by above-mentioned control principle control, thereby open the 3rd test loop, control portable terminal 260 simultaneously and enter corresponding test pattern.The audio input end M of external earphone 261 receives audio frequency instrument 230 with the audio signal of electrical signal form output through audio frequency switching device 210 then, and transmit it to the boombox 264 of portable terminal 260, boombox 264 converts the audio signal of this signal of telecommunication voice signal to and transfers to artitificial ear 270, convert this voice signal to the signal of telecommunication by artitificial ear 270 again, be back to audio frequency instrument 230 by audio frequency switching device 210.
Step S150: according to the audio-frequency test result of three kinds of test loops, judge whether the audio frequency of portable terminal is qualified.
If have the audio-frequency test of at least one defective in the test loop in three, judge that then the audio-frequency test of portable terminal is defective, and correspondence demonstrates underproof test loop, so that the tester can carry out follow-up debugging targetedly.
In sum, the present invention selects at least a in three kinds of test loops that portable terminal is carried out audio-frequency test by utilizing the PC control audio frequency switching device, wherein first test loop is through artificial mouth from the audio frequency instrument, the built-in microphone of portable terminal and the audio output of external earphone return the audio frequency instrument, second test loop is from the audio input end of audio frequency instrument through external earphone, built-in receiver and the artitificial ear of portable terminal return the audio frequency instrument, the 3rd test loop is from the audio input end of audio frequency instrument through external earphone, the boombox of portable terminal and artitificial ear return the audio frequency instrument, thereby not only can eliminate the manual operation factor to audio-frequency test result's influence, and can effectively reduce artificial mouth sends in the loop test audio signal by the direct-coupled risk of artitificial ear, improved audio-frequency test result's accuracy and stability, it is low to be convenient to debugging and cost.
The above only is embodiments of the invention; be not so limit claim of the present invention; every equivalent structure or equivalent flow process conversion that utilizes specification of the present invention and accompanying drawing content to do; or directly or indirectly be used in other relevant technical fields, all in like manner be included in the scope of patent protection of the present invention.
