Detailed Description
The following describes embodiments of the present invention in further detail with reference to the accompanying drawings.
The earphone consistency test method provided by the invention is executed in an earphone consistency test system shown in fig. 4, and the system comprises a first test station 41, a first test terminal 42 and a second test station 43; here, the first test station 41 and the second test station 43 arrange processes according to the specific situation on the product test line, and the first test station 41 precedes the second test station in the test process.
With reference to the above earphone consistency test system, the earphone consistency test method provided by the present invention, as shown in fig. 3, includes the following steps:
step S31: all earphones were tested to obtain sound pressure data.
This step is performed at a first test station 41, which performs a performance test on all the single-earphone products (including the left-ear product and the right-ear product) to obtain sound pressure data for each single earphone.
Step S32: and rejecting earphones which do not meet the performance requirement of the single ear based on the sound pressure data.
This step is implemented on the first test terminal 42, and for the requirement of single earphone performance, it is generally determined in the industry that sound pressure fluctuation belongs to a product with qualified performance within the range of 20HZ to 20000HZ and within ± 5DB, after sound pressure data of all earphones is obtained by testing, performance is judged based on the sound pressure data of each earphone, earphone products which do not conform to the requirement of single earphone performance are removed, and qualified products are left.
The earphones with poor single-ear performance can be effectively intercepted through the step, and the problem that a pair of defective products are generated due to the fact that consistency tests of the two earphones are not qualified when the rear ends are paired can be avoided by timely finding out single defective products at the front ends.
Step S33: and determining the first frequency point with the largest difference based on the sound pressure data of the qualified earphones.
In combination with the sound pressure data of all qualified earphones, as shown in the sound pressure curve diagram of fig. 5, the sound pressures of all earphones on the same frequency point have differences, and the first frequency point a with the largest difference in sound pressure is found out, that is, the sound pressure value difference is the largest on the first frequency point a.
Step S34: and grading at set intervals on the first frequency point.
The maximum sound pressure value and the minimum sound pressure value are upper and lower limits at the first frequency point a, and the sound pressure values are classified at the first frequency point a at set intervals, for example, the sound pressure difference at the first frequency point a is 6DB, and the interval 1DB is set, so that the first frequency point a is classified into six stages a1, B1, C1, D1, E1, and F1, and each stage interval 1 DB.
Step S35: and determining the first gear of each qualified earphone.
For each qualified earphone, based on the sound pressure data and the gear divided in step S34, the gear to which each qualified earphone belongs on the first frequency point a is determined, for example, earphone 1 is divided into gear a1 on the first frequency point a, earphone 2 is divided into gear C1 on the first frequency point a, and the like.
In some embodiments of the present invention, as shown in fig. 4, after determining the first gear to which all the qualified earphones belong, the first testing terminal 42 sends the sound pressure data of each qualified earphone and the first gear information to which the qualified earphone belongs to the management system 44, the management system 44 stores the sound pressure data of each qualified earphone and the first gear information to which the qualified earphone belongs, and generates a two-dimensional code for each qualified earphone, and after the two-dimensional code is at the next first testing station 41, the two-dimensional code may be attached to each qualified earphone in a manner of attaching a two-dimensional code label, spraying a two-dimensional code, and the like at a subsequent station for use in subsequently acquiring information of the earphones.
Step S36: and according to the first gear of each qualified earphone, implementing earphone pairing according to the nearest gear pairing rule.
The step is implemented on a second testing station 43, a scanning terminal is configured on the second testing station 43, and the sound pressure data and the first gear information of the qualified earphones can be obtained by scanning the two-dimensional code on the qualified earphones through the scanning terminal.
After the first gear of each qualified headset is determined according to the steps, the same-gear headset is classified, when the right and left ears are paired, the method is implemented based on a most recent gear pairing principle, namely, the right and left ears in the same gear or adjacent gears are paired, for example, the left headset in the gear A1 can be preferentially paired with the right headset in the gear A1, after the right headset in the gear A1 is paired, if the left headset in the gear A1 still exists, the right headset in the adjacent gear, namely the gear B1 is paired, if the right headset in the gear B1 also finishes pairing, the headset in the gear-separating position, namely the right headset in the gear C1 is paired, and if the left headset in the gear A1 which is not paired exists, the subsequent processing is left.
After obtaining the first gear information of each qualified earphone by scanning the two-dimensional code of each qualified earphone, classifying the left earphone and the right earphone according to the gear respectively based on the first gear information, determining the number of the left earphone and the right earphone of each gear, and performing pairing with the side with the large number of earphones as a pairing reference during pairing, for example, in the a1 gear, if the number of the left earphones is more than the number of the right earphones, selecting the pairing from the right earphones by using the left earphone as the pairing reference and using the nearest gear pairing rule.
In the preferred embodiment of the present invention, based on the principle of maximizing gear matching, under the definition of the most recent gear matching rule, gear-separating matching is prioritized, after gear-separating matching, if there are remaining unpaired products, then matching continues according to adjacent gears, after adjacent gear-separating matching, if there are remaining unpaired products, then matching according to the same gear, if there are remaining unpaired left earphones in gear a1, then subsequent processing is left.
Taking the left earphone of the a1 gear in the table one below as an example, the left earphone can be preferentially paired with the right earphone belonging to the C1 gear, after the right earphone belonging to the C1 gear is paired, if the left earphone of the a1 gear still exists, the right earphone belonging to the B1 gear is paired with the adjacent gear, if the right earphone belonging to the B1 gear also exists, the right earphone belonging to the same gear, that is, the right earphone belonging to the a1 gear is paired, and if the left earphone of the a1 gear which is not paired still exists, the subsequent processing is left.
