The touch control screen 22 is located below the second protective cover 12 and is arranged opposite to the touch hole on the second protective cover 12; the measurement and control main board 21 is located below the first protective cover 11. The first protective cover 11 is provided with a detection hole, and the detection hole is arranged opposite to the connecting device 3.

[0032] like Figures 4 to 6 As shown, to enable quick assembly and disassembly of the voice module 9, the connecting device 3 includes a connector 31 and a probe 32. The connector 31 is fixed to the measurement and control mainboard 21 via screws. The connector 31 is provided with a positioning slot 311 that matches the voice module 9. The positioning slot 311 is also located below the clamping device 4. The probe 32 is fixed to the bottom of the positioning slot 311. The probe 32 corresponds to the pin on the voice module 9 and is electrically connected to the measurement and control device 2 via a wire. The probe 32 connects the voice module 9 to the measurement and control device 2. The probe 32 is used for signal transmission and power supply.

[0033] In order to facilitate the installation and removal of the voice module 9 in the positioning groove 311, grab and release grooves 312 are provided on both sides of the positioning groove 311. The grab and release grooves 312 are connected to the positioning groove 311, making it convenient for fingers to grab the voice module 9 from both sides.

[0034] like Figure 6As shown, in order to automatically detect the voice module 9 and automatically power on and off the voice module 9 to avoid live operation, the connecting device 3 also includes a needle sleeve 33. The needle sleeve 33 is installed on the connecting base 31 and connected to the probe 32. The needle sleeve 33 corresponds to the probe 32 one by one and is used to adjust the height of the probe 32. The height of the needle sleeve 33 on the connecting base 31 is used to adjust the length of the probe 32, thereby achieving different timings of the signal detection signals of the signal pin. The system uses this timing difference to automatically power on and off, avoiding live operation of the voice module 9.

[0035] To prevent the pressing device 4 from crushing the voice module 9 while ensuring the pressing force of the voice module 9 and ensuring reliable electrical conduction, the connecting device 3 also includes an elastic component. The elastic component is mounted on the measurement and control mainboard 21 and connected to the connecting seat 31.

Specifically, the elastic component includes an elastic seat 34, an elastic guide rod 35, and a connecting spring 36. The elastic seat 34 is fixed to the measurement and control mainboard 21 by screws. Two elastic guide rods 35 are symmetrically provided. The elastic guide rods 35 are fixed to the elastic seat 34 and slidably connected to the connecting seat 31. The elastic guide rods 35 guide the connecting seat 31, allowing the connecting seat 31 to rise and fall in the vertical direction. The connecting spring 36 is movably mounted on the elastic guide rod 35. The two ends of the connecting spring 36 respectively abut against the elastic seat 34 and the connecting seat 31, and the connecting spring 36 keeps the connecting seat 31 in an elastically rising and falling state. In order to reduce the friction between the connecting seat 31 and the elastic guide rod 35 , a shaft sleeve 37 is installed on the connecting seat 31 . The shaft sleeve 37 is movably inserted into the elastic guide rail, and the connecting spring 36 abuts against the shaft sleeve 37 .

[0036] In order to prevent the connecting seat 31 from detaching from the elastic guide rod 35, limit the height of the connecting seat 31, and protect the connection between the probe 32 and the measurement and control main board 21, the elastic component also includes a limit screw 38. The threaded column of the limit screw 38 is installed on the elastic seat 34. The limit screw 38 is also movably inserted into the limit hole 314 of the connecting seat 31. The nut of the limit screw 38 limits the lifting height of the connecting seat 31.

[0037] To improve the accuracy and reliability of the test, two digital microphones 6 are provided, mounted on either end of a test board 61 secured to one side of the test box 5. This facilitates the installation of the microphones 6. To prevent interference with the echo test caused by a tight seal within the test box 5, two test holes 51 are provided on the test box 5, located at either end of the test board 61.

[0038] The center of speaker 7 is coplanar with the center of microphone 6.

The wires connected to microphone 6 and speaker 7 are secured to test bench 1 via wire clips to prevent them from interfering with each other. Small speaker 72 is located on the same side wall of test box 5 as large speaker 71. Small speaker 72 plays voice, while microphone 6 recognizes the voice and automatically determines the voice recognition function. Large speaker 71 plays a 1 kHz 0 dB sound source. Large speaker 71 and small speaker 72 are also connected to power amplifier board 73.

[0039] To facilitate assembly and disassembly of the voice module 9 and ensure reliable compression, the compression device 4 includes a compression frame 41, a compression drive assembly 42, a lifting assembly 43, and a compression block 44. The compression frame 41 is fixed to the top of the test bench 1 and is located on one side of the measurement and control mainboard 21. The compression drive assembly 42 is mounted on the top of the compression frame 41 and connected to the lifting assembly 43. The compression block 44 is mounted on the bottom of the lifting assembly 43 and is arranged opposite the connecting device 3. It is used to compress the voice module 9 to the connecting device 3 via the lifting assembly 43 and the compression drive assembly 42. The compression drive assembly 42 can be a toggle clamp, which has a simple structure and is easy to use. Lifting assembly 43 includes a lifting connecting rod 431, a lifting plate 432, and a lifting guide rod 435. Two lifting guide rods 435 are symmetrically arranged. Lifting guide rods 435 are fixed to the top of test bench 1 and located on one side of compression frame 41. Lifting plate 432 is movably inserted into lifting guide rod 435 and connected to the bottom of lifting connecting rod 431. The top of lifting connecting rod 431 is connected to a toggle clamp. A compression block 44 is mounted on the bottom of lifting plate 432 and matches the voice module 9.

[0040] In order to keep the lifting plate 432 away from the connecting seat 31 in the free state, a lifting spring 436 is further installed on the lifting guide rod 435, and the two ends of the lifting spring 436 respectively abut against the lifting plate 432 and the test bench 1.

[0041] In order to facilitate the adjustment of the height of the pressing block 44 , the pressing block 44 is connected to the lifting plate 432 via an adjusting column 433 . The length of the adjusting column 433 can be set as needed to adjust the height of the pressing block 44 .
