As shown in fig. 1, the testing system 100 for testing the performance of the microphones FR, VDC and current provided by the present invention comprises: a test condition configuration module 110, a test procedure processing module 120, and a test result handling module 130.
Specifically, the test condition configuration module 110 is configured to configure test conditions for testing the performance of the microphones FR, VDC and current. Configuration options are provided in the test condition configuration module 110, by which test conditions for the microphone FR, VDC and current capabilities are configured.

To further illustrate the specific structure of the test condition configuration module 110, FIG. 2 shows the logical structure of the test condition configuration module according to an embodiment of the present invention.
As shown in fig. 2, the test condition configuration module 110 includes: an FR test condition configuration unit 111, a VDC test condition configuration unit 112, and a current test condition configuration unit 113.
The FR test condition configuration unit 111 is configured to configure a test condition of the microphone FR to be tested; a VDC test condition configuration unit 112 for configuring test conditions of the microphone VDC to be tested; and a current test condition configuration unit 113, configured to configure a test condition of the current of the microphone to be tested.
In the embodiment of the present invention, configuration options are set in the test condition configuration module 110, and the FR test condition configuration unit 111, the VDC test condition configuration unit 112, and the current test condition configuration unit 113 are set in the configuration options. If three performance values of the microphone FR, VDC and current are to be tested, the test conditions of FR, VDC and current are selected in the configuration options, and after the setting button is clicked, the FR test condition configuration unit 111, the VDC test condition configuration unit 112 and the current test condition configuration unit 113 automatically configure the corresponding performance test conditions. Therefore, in the embodiment of the present invention, the test conditions of the three performances of the microphone FR, VDC and current are automatically configured by the test condition configuration module 110, so that the error rate of manually configuring the test equipment can be reduced.
To further illustrate the specific logical structure of the test procedure processing module 120, FIG. 3 shows the logical structure of the test procedure processing module according to an embodiment of the present invention. As shown in fig. 3, the test procedure processing module 120 includes: a performance test unit 121, a data acquisition unit 122, and a test result display unit 123.

When the test results are read, all performance values over a certain time, including outliers, are recorded as final results. Compared with the method that an operator directly reads the fluctuating numerical value, the test system eliminates the subjective consciousness of manual reading and improves the accuracy.
In an embodiment of the present invention, the test result handling module 130 directly saves the data output of the final test into the corresponding test file. The corresponding test file specifically refers to which performance of the microphone is tested, and the final test result is stored in which performance test file, for example: the FR performance of the test microphone is saved to the FR test file if it is. Compared with the manual data export, the data processing and conversion are needed, and the test system provided by the invention improves the accuracy and efficiency of data output.
Corresponding to the test system, the invention also provides a test method for the performance of the microphones FR, VDC and current, and fig. 4 shows the flow of the test method for the performance of the microphones FR, VDC and current according to the embodiment of the invention.
As shown in fig. 4, the testing method for the performance of the microphone FR, VDC and current provided by the present invention adopts the testing system for the performance of the microphone FR, VDC and current to perform testing, and the specific testing method includes steps S110 to S140, and the specific testing method includes the following steps:
s110: configuring test conditions of the FR, VDC and current performance of the microphone in the test condition configuration module according to the test requirements of the microphone to be tested;

s130: processing the tested performance data, and displaying the test result after the performance data is processed;
s140: and exporting and storing the test result.
In step S110, in the process of configuring the test conditions of the microphones FR, VDC and current performance to be tested in the test condition configuration module according to the test requirements of the microphones to be tested, the test conditions of the microphones FR, VDC and current performance are configured through the configuration options in the test condition configuration module; in the configuration options, testing conditions for testing FR, VDC and current of the microphone are sequentially configured by selecting options of an FR testing condition configuration unit, a VDC testing condition configuration unit and a current testing condition configuration unit.
In step S130, the process of processing the tested performance data and displaying the processed test result specifically includes the following steps:

For example: if the system needs to test three performance values of the microphone FR, the microphone VDC and the microphone current, a tester selects the test conditions of the FR, the microphone VDC and the microphone current in the configuration options, and after clicking a setting button, the FR test condition configuration unit, the VDC test condition configuration unit and the microphone current test condition configuration unit can automatically configure the corresponding performance test conditions.
It should be noted that, if the system only needs to test two of the three performances, in the configuration selection, only two of the three performances are selected to complete the automatic configuration, so that the corresponding configuration unit can be selected in the test condition configuration module 110 according to the test requirement. In the embodiment of the invention, the test conditions of the microphone FR, the microphone VDC and the current are automatically configured by the test condition configuration module, so that the error rate of manually configuring the test equipment can be reduced.

In the test result handling module 130, the tester determines whether to continue the test or retest according to the test result, that is, if the test result has a significant deviation from the standard performance of the product, the test can be retested, and in the operation process, the "Restart" button is clicked to retest the performance of the product, and further confirm whether the performance of the product is qualified. After testing of all the microphone products to be tested is completed, the "Export" button is clicked, and after the names of the test files are filled in the popped dialog boxes, the test result processing module 130 outputs and stores the finally tested data into the corresponding test files.
In the testing process of the invention, the FR, VDC and current can be tested in sequence by only placing the product once, thereby avoiding the damage to the product when the product is taken and placed for many times, reducing the error rate of manually switching the testing items and improving the testing efficiency.
According to the test system and the test method for the performance of the microphone FR, the microphone VDC and the current, which are provided by the invention, the test conditions of the performance of the microphone FR, the performance of the microphone VDC and the performance of the microphone to be tested are automatically configured through the test condition configuration module, so that the error rate of manually configuring test equipment can be reduced, and the debugging time is saved; the performance test of each test item is carried out in sequence according to the configured test conditions, so that damage to a microphone product to be tested when the microphone to be tested is taken and placed for multiple times can be avoided, the error rate of manually switching the test items is reduced, and the test efficiency is improved; data are exported through the test result processing module, and compared with manually exported data, the accuracy and the efficiency of data output can be improved.
