Embodiment
As shown in Figure 1, be the flow chart of audio hardware equipment detection method.
A kind of audio hardware equipment detection method, comprises the following steps:
Step S110, is separated into left and right sound channels audio file successively by audio hardware device plays to be detected, gathers the left and right sound channels output voltage of audio hardware equipment to be detected by the audio file of default hertz sine wave.
In the present embodiment, the audio file presetting hertz sine wave is the audio file of 1KHz sine wave.The frequency of the audio file of 1KHz sine wave is determined by the capacitance resistance value in follow-up hardware integration module, and namely frequency is corresponding with capacitance resistance value.And sine wave must be adopted just to collect stable magnitude of voltage.
The concrete mode adopting audio frequency apparatus to be detected to play the audio file presetting hertz sine wave is: the audio file of default hertz sine wave is isolated left audio file and the also gradation broadcasting respectively of right audio channel file.
If the audio file of default hertz sine wave not to be isolated left audio file and the also gradation broadcasting respectively of right audio channel file, but adopt the words simultaneously playing left and right acoustic channels audio file, then in the gatherer process of left and right acoustic channels output voltage, the output voltage of two sound channels can be bonded together, interact both sides, cause voltage acquisition inaccurate, thus can interference be there is.And by left and right sound channels audio file respectively gradation play, and gradation gathers the output voltage of left and right acoustic channels, interference when can reduce voltage acquisition between left and right acoustic channels, makes testing result more accurate.
When gathering the left and right sound channels output voltage of audio hardware equipment to be detected, multi collect can be adopted to average, to improve detection accuracy.Such as, gather left and right sound channels output voltage ten times respectively, get the mean value of ten times, as left and right sound channels output voltage, and carry out next step.
Step S120, carries out power amplification, filtering process successively by the output voltage of left and right sound channels respectively.
Power amplifier chips HWD2108 is adopted to carry out power amplification process to the output voltage of left and right sound channels respectively.
The filtration module of diode composition is adopted to carry out filtering process to the output voltage of left and right sound channels respectively.
Step S130, is converted to galvanic current pressure by the left and right sound channels output voltage after carrying out power amplification, filtering process respectively.
Hardware integration module is adopted respectively the output voltage of left and right sound channels to be converted to galvanic current pressure.
Left and right sound channels output voltage is stable direct voltage after carrying out power amplification, filtering, voltage transitions process successively.
For R channel output voltage, R channel output voltage carries out power amplification via power amplifier chips HWD2108, filtration module through diode composition carries out filtering, by the negative voltage filtering in second cycle of sine wave, is stable direct voltage finally by hardware integration module by voltage transitions.
During owing to measuring alternating voltage, actual what record is the rectified mean value of signal, according to the Relationship of Coefficients of sinusoidal wave effective value and rectified mean value, calculates effective value, there is comparatively big error.If the audio frequency play is non-sinusoidal waveform audio frequency, error is larger.Therefore, measure after the output voltage of left and right sound channels being converted to galvanic current pressure, the error in computational process can be avoided, make testing result more accurate.
Step S140, judge that the left and right sound channels direct voltage after changing is whether all in threshold voltage ranges respectively, if play in left and right sound channels audio file process respectively, left and right sound channels direct voltage after conversion all in threshold voltage ranges, then thinks that audio hardware equipment Inspection to be detected is qualified.
The determination mode of threshold voltage is as follows: the sine wave of predeterminated frequency is isolated left and right acoustic channels audio file and determining qualified audio frequency apparatus is play, gather the output voltage of its left and right acoustic channels and convert galvanic current pressure again to through power amplification, filtering process, measure this galvanic current pressure, and using this galvanic current pressure as threshold voltage.
The determination mode of threshold voltage ranges is as follows: threshold voltage ranges is the empirical value jointly determined by the resistance value in the frequency of audio file, hardware integration module, capacitance.The threshold voltage ranges of 1Khz pure tone frequency file is adopted to be defined as ± 200mv.
In the present embodiment, when audio hardware equipment is normal, when playing left audio file, L channel is only had to have output voltage.When audio hardware equipment has a fault, when playing left audio file, R channel also has output voltage.R channel displaying audio file principle is the same.Therefore, in each testing process, all need to gather left and right acoustic channels output voltage simultaneously and carry out judgement and compare, to carry out comprehensive test.
Concrete detection method can be as follows:
(1) audio file of default hertz sine wave is isolated left audio file and right audio channel file.
(2) with audio hardware device plays left audio file to be detected, gather the output voltage of L channel and R channel, and power amplification, filtering and voltage transitions process are carried out successively to the left and right acoustic channels output voltage collected; Judge that the left and right sound channels direct voltage after changing is whether in threshold voltage ranges; If not, then think that audio hardware equipment Inspection is not passed through.
(3) with audio hardware device plays right audio channel file to be detected, gather the output voltage of L channel and R channel, and power amplification, filtering and voltage transitions process are carried out successively to the left and right sound channels output voltage collected; Judge that the left and right sound channels direct voltage after changing is whether in threshold voltage ranges; If not, then, audio hardware equipment Inspection is not passed through.
In above-mentioned testing process only when playing left and right acoustic channels audio file, the output voltage of left and right acoustic channels meets testing requirement simultaneously, and audio hardware equipment is just qualified; As long as when playing left audio file or right audio channel file, have one not meet testing requirement in the output voltage of left and right acoustic channels, then judge that audio hardware equipment Inspection is defective, detection of end.
Above-mentioned detection method also first can be play right audio channel file and detect, detect by after play left audio file again and detect, at this not to limit the present invention.
Above-mentioned audio hardware equipment detection method adopts audio hardware device plays to be detected to preset the audio file of hertz sine wave, the audio file of default hertz sine wave is isolated left audio file and right audio channel file is play respectively on audio hardware equipment to be detected, detect left and right sound channels respectively, left and right sound channels output voltage is gathered in testing process, and power amplification, filtering and voltage transitions process are carried out successively to the left and right acoustic channels output voltage gathered, judge that the left and right sound channels direct voltage after conversion is whether in threshold voltage ranges.If play respectively in left and right sound channels audio file process, the left and right sound channels direct voltage after conversion all in threshold voltage ranges, then thinks that audio hardware equipment to be detected is qualified, otherwise, think defective.Above-mentioned testing process is without the need to artificial participation, and testing process is the power amplification of output voltage, filtering and voltage transitions process, and amount of calculation is simple, judges that whether audio hardware equipment is qualified therefore, it is possible to fast and convenient.
