In order to enable technical solution of the present invention is clearer, it is explained for a specific example below.Fig. 2
It is the specific flow chart that a kind of inspection earphone of one embodiment of the invention wears the method for consistency.Method as shown in Figure 2
Include the following steps:
201, the loudspeaker of one section of steady-state audio signals to left and right earphone are sent, so that left and right earphone plays stable state audio letter
Number.
Steady-state audio signals refer to the audio signal of energy constant.Steady-state audio signals are binaural signal, steady tone
Frequency signal includes white noise or pink noise etc., wherein white noise refers to the power of the frequency component in one section of sound whole
It is all uniform in a range of audibility (0~20kHZ).Due to human ear this sound sensitive to high frequency sound be very noisy ear sand
Sha Sheng.The characteristics of white noise is that the energy of each frequency range is uniform (frequency spectrum is similar to solar spectrum i.e. white-light spectrum).Pink noise is certainly
The most common noise in right boundary, in brief, the power of the frequency component of pink noise is mainly distributed on middle low-frequency range.From waveform angle
Degree sees that pink noise divides shape, in a certain range audio data have same or similar energy, pink noise be
Low-frequency range is by force at the weak noise of high band (the similar partially red spectrum, that is, pink spectrum of spectrogram).The loudspeaker of right earphone are sent to the left
The energy of each frequency range of the signal that steady-state audio signals play out loudspeaker is uniformly that the wearing convenient for judging left and right earphone is close
Closing property.It should be noted that the human ear range of audibility is in 20~20kHz.In addition, when earphone wearing airtightness is inadequate or gas leakage
When, it is mainly larger to low-frequency effects, therefore white noise and pink noise can satisfy the inspection earphone wearing of the application completely
Airtightness, and then examine the demand of earphone wearing consistency.In practical applications, can also with the frequency of customized audio signal,
As long as meeting the needs of examining left and right earphone to wear consistency.
202, the feedback microphones for receiving left and right earphone respectively collect voice signal.
For purposes of illustration only, right earphone is adopted for example, the collected voice signal of left earphone is defined as the first voice signal
The voice signal collected is defined as second sound signal.It should be noted that the feedback microphones of left and right earphone are separately positioned on
2. the front of the loudspeaker of left and right earphone is earphone horn, is 3. feedback microphones, just as shown in figure 3, being 1. shell for earphone
In the voice signal that the loudspeaker that the feedback microphones of left and right earphone sufficiently collect left and right earphone issue.
203, the sound pressure level of left and right earphone is calculated according to collected signal.Such as left ear is calculated according to the first voice signal
The sound pressure level of machine is SLIt (dB), is S according to the sound pressure level that second sound signal calculates right earphoneR(dB).It should be noted that sound
Arbitrarily downgrade is the most basic parameter for reflecting acoustical signal power, the measurement unit generallyd use in acoustic measurement.
204, the sound pressure level of left and right earphone is judged whether not less than sound pressure level a reference value, if so, executing step 205；If
It is no, execute step 209.In other words, only as the sound pressure level S of left earphoneL(dB) and the sound pressure level S of right earphoneR(dB) simultaneously not
When less than sound pressure level a reference value (for example, 92dB), step 205 is executed；As long as the sound pressure level S of left earphoneL(dB) and right earphone
Sound pressure level SR(dB) there is a sound pressure level to be less than sound pressure level a reference value in, then follow the steps 209.
It should be noted that being said when the sound pressure level of certain machine of picking up the ears (left earphone and/or right earphone) is arbitrarily downgraded less than reference sound intensity
The wearing airtightness of the bright machine of picking up the ears is poor, needs to adjust the wearing position of the machine of picking up the ears at this time or replaces the ear of different model
Set, makes the sound pressure level of the machine of picking up the ears arbitrarily downgrade not less than reference sound intensity.Only when the sound pressure level of left and right earphone is not less than reference acoustic pressure
Grade when the wearing airtightness of i.e. left and right earphone is good, just carries out the judgement that earphone wears consistency.
205, the difference of the sound pressure level of the first voice signal and the sound pressure level of second sound signal is calculated；SR(dB)-SL
(dB), and 206 are entered step.
206, judge the difference S of the sound pressure level of the first voice signal and the sound pressure level of second sound signalR(dB)-SL(dB)
Whether in threshold range, if so, executing step 207；If it is not, executing step 208.
The threshold range can be defined according to the actual situation, threshold range be, for example, (0dB, 6dB].In practical application
In, reasonable threshold value can be selected to test according to actual needs.If environment locating for user is relatively quiet, that
Threshold value can be arranged larger；If environment described in user is relatively noisy, threshold value can be arranged
It is smaller.As long as realizing that user is adjusted threshold value, even when user is in different environments, audio and the noise reduction effect of earphone
Fruit can still reach optimum state.Certainly, the consistency inspection that the smaller left and right earphone of the threshold value being arranged in environment of the same race is worn
The result of survey is more accurate.
207, it is poor to judge that left and right earphone wears consistency.It should be noted that in practical applications, judging left and right
When earphone wearing consistency is poor, it can also indicate that the wearing position for adjusting corresponding earphone or replace the ear muff of different model,
Then one section of steady-state audio signals is sent again, continues to examine adjustment earphone wearing position or replaces the ear muff of different model
Afterwards, whether the wearing of left and right earphone is consistent.
208, it is good to judge that left and right earphone wears consistency.
209, as the sound pressure level S of left earphoneL(dB) and the sound pressure level S of right earphoneR(dB) sound pressure level is less than acoustic pressure in
When grade a reference value (for example, 92dB), then only the wearing position of the instruction adjustment lesser machine of picking up the ears of sound pressure level or replacement are different
Then the ear muff of model sends one section of steady-state audio signals again, continues to examine so that the machine of picking up the ears reaches optimal wearing state
Test adjustment this pick up the ears machine wearing position or replace different model ear muff after, whether the wearing of left and right earphone consistent.
As the sound pressure level S of left earphoneL(dB) and the sound pressure level S of right earphoneR(dB) simultaneously be less than sound pressure level a reference value (for example,
When 92dB), then the wearing position of adjustment left and right earphone is indicated simultaneously or replaces the ear muff of different model, so that earphone reaches most
Then good wearing state sends one section of steady-state audio signals again, continue to examine adjustment earphone wearing position or replacement not
After the ear muff of model, whether the wearing of left and right earphone is consistent.
It should be noted that if earphone to be detected is headphone, this method can scientific guidance user adjustment earphone
Wearing position, so that left and right earphone is worn unanimously, so that the audio of earphone and noise reduction effect reach best；If to be detected
Earphone is In-Ear Headphones, can help user judges whether the ear muff size of earphone is suitable by this method, to select difference
The ear muff of model makes earphone reach optimal wearing state, so that the audio of earphone and noise reduction effect reach best.
