[0068] Step S106, performing Fourier transform on the third audio information to obtain a second audio spectrum;

[0069] Step S107: determining a test result of the product to be tested according to the second audio spectrum.

[0070] Specifically, this application is applicable to the smart home field. The product under test can be a camera. In addition to its shooting function, the camera also has a calling function. By connecting to Wi-Fi (wireless fidelity), remote video communication can be achieved through a dedicated app (Application). During the production inspection stage of the product under test, it is necessary to test the reception and playback functions of the product under test.

[0071] To ensure that the product is not disturbed by external noise during testing, all testing mechanisms are installed in a shielded box lined with soundproofing cotton to eliminate external interference. The microphone is mounted above the product under test, with an external soundproof cover that can be adjusted in height via a micro-slide to accommodate different product models. The player is installed below the product under test and connected to the baseplate.

[0072] When the DUT is in the testing state, the microphone, DUT, and player are aligned vertically.

[0078] Step S202: if the number of first audio frames exceeds a preset number, comparing the first audio spectrum with a normal spectrum;

[0079] Step S203: If the similarity between the first audio spectrum and the normal spectrum is greater than a preset value, the audio test is qualified;

[0080] Step S204: If the similarity between the first audio spectrum and the normal spectrum is less than a preset value, the audio test fails.

[0081] Specifically, when performing a radio function test, the host computer will establish a P2P connection with the product under test. The player plays the first audio information according to the first control instruction information; the host computer collects the first audio information within a preset time period, performs Fourier transform on the first audio information, and obtains the first audio spectrum; the first audio frames that meet the first preset frequency are screened out from the first audio spectrum; wherein, the first preset frequency can be 1 kHz; if the number of first audio frames exceeds the preset number, it means that the host computer has successfully received the first audio information of the camera, and at this time, the first audio spectrum is compared with the normal spectrum; if the similarity between the first audio spectrum and the normal spectrum is greater than the preset value, the audio test is qualified; if the similarity between the first audio spectrum and the normal spectrum is less than the preset value, the audio test is unqualified. wherein, the preset number is 10 frames.

[0085] Step S303: If the similarity between the second audio spectrum and the normal spectrum is greater than a preset value, the product under test passes the test;

[0086] Step S304: If the similarity between the second audio spectrum and the normal spectrum is less than a preset value, the product under test fails the test.

[0087] Specifically, the host computer sends a second control instruction information to the player through the serial port, so that the player plays the second audio information according to the second control instruction information; after the second control instruction information is successfully sent, the host computer obtains the third audio information received by the microphone according to the second audio information; the third audio information is Fourier transformed to obtain a second audio spectrum; the number of second audio frames that meet the second preset frequency is screened out from the second audio spectrum; wherein the second preset frequency is 2khz; if the number of second audio frames exceeds the preset number, it means that the product to be tested is playing normally; at this time, the second audio spectrum is compared with the normal spectrum. If the similarity between the second audio spectrum and the normal spectrum is greater than the preset value, the product to be tested passes the test; if the similarity between the second audio spectrum and the normal spectrum is less than the preset value, the product to be tested fails the test.

[0088] Furthermore, the method further comprises the following steps:

[0089] Step S401, identifying the product to be tested and reading the production product information of the product to be tested;

[0090] Step S402: Bind the production product information with the test results of the product to be tested.
