The switching and carrier mechanism 2 is used for placing the mobile phone to be tested. The switching and carrier mechanism 2 is composed of a support frame 21, a switching screw module 22 and a placement carrier 23. The support frame 21 is fixedly connected to the surface of the base 1 by bolts, and the switching screw module 22 is installed on the top of the support frame 21, and the placement carrier 23 is fixed on the sliding seat of the switching screw module 22. The placement carrier 23 is used for placing and clamping the mobile phone to be tested.

[0021] During implementation, the screw module 22 is switched to drive the placement carrier 23 to slide along the support frame 21 and extend. After extending, the mobile phone to be tested is placed inside the placement carrier 23 for clamping, and then the screw module 22 is switched to drive the placement carrier 23 to reset.

[0022] Furthermore, if Figure 2 as well as Figure 3 As shown, a button pressing mechanism 3 is installed on the surface of the base 1 and on the left and right sides of the switching and carrier mechanism 2. The button pressing mechanism 3 is used for pressing the buttons of the mobile phone to be tested. The button pressing mechanism 3 includes a support seat 31, a pressing assembly 32 and a sound insulation box 33. The support seat 31 is fixedly connected to the surface of the base 1, and the sound insulation box 33 is installed on the top of the support seat 31. A pressing assembly 32 is installed on the surface of the support seat 31 and inside the sound insulation box 33. The pressing end of the pressing assembly 32 extends to the outside of the sound insulation box 33 and is used for pressing the buttons of the mobile phone to be tested.

[0023] During implementation, the buttons are pressed by the pressing assembly 32 on the surface of the support seat 31. During the pressing process, the noise generated by the movement of the pressing assembly 32 itself will be isolated by the sound insulation box 33. Noise will be generated after the pressing assembly 32 presses the buttons of the mobile phone to be tested.

[0024] Furthermore, if Figure 5 as well as Figure 6 As shown, a left collecting mechanism 5 is provided on the left side of the switching and carrier mechanism 2, and the left collecting mechanism 5 is installed on the surface of the base 1, and the left collecting mechanism 5 is used for collecting noise after the key of the mobile phone to be tested is pressed by the key pressing mechanism 3 on the left side. The left collecting mechanism 5 includes an X-axis sliding module 51, a Y-axis sliding module 52, a left adjustment frame 53 and a left microphone 54. The X-axis sliding module 51 is installed on the surface of the base 1 by bolts, and the Y-axis sliding module 52 is installed on the top of the X-axis sliding module 51, and the left adjustment frame 53 is installed on the surface of the Y-axis sliding module 52, and three groups of left microphones 54 are installed on the surface of the left adjustment frame 53. The left microphone 54 is used for collecting noise after the key of the mobile phone to be tested is pressed by the sound insulation box 33 on the left side.

[0025] During implementation, the X-axis sliding module 51 drives the Y-axis sliding module 52 to move to a suitable position, and then the Y-axis sliding module 52 drives the left adjustment frame 53 to move. After the movement, the left microphone 54 on the surface of the left adjustment frame 53 collects the pressing noise of the left button of the mobile phone to be tested.

[0026] Furthermore, if Figure 4 as well as Figure 6As shown, a right collection mechanism 4 is installed on the surface of the base 1 and on the right side of the switching and carrier mechanism 2. The right collection mechanism 4 is used for collecting noise after the keys of the mobile phone to be tested are pressed by the key pressing mechanism 3 on the right side. The right collection mechanism 4 is composed of a right support platform 41, a right adjustment frame 42 and a right microphone 43. The right support platform 41 is fixedly connected to the surface of the base 1, and the right adjustment frame 42 is fixed to the sliding end of the right support platform 41. The right microphone 43 is installed on the sliding end of the right adjustment frame 42. The right microphone 43 is used for collecting noise after the keys of the mobile phone to be tested are pressed by the sound insulation box 33 on the right side.

[0027] During implementation, the position of the right adjustment frame 42 on the right support platform 41 is adjusted, and the right adjustment frame 42 and the right support platform 41 are fixed after adjustment, and the right microphone 43 on the surface of the right adjustment frame 42 is used to collect the pressing noise of the right button of the mobile phone to be tested.

[0028] The utility model improves the automation degree of the test, does not need manual auxiliary operation during the test process, reduces the labor intensity of mobile phone button testing during the test process, and improves the work efficiency during mobile phone button testing; and by covering the surface of the pressing component 32 with a sound insulation box 33, the sound insulation box 33 can isolate the noise generated by the movement of the pressing component 32 itself, avoiding the collection of the microphone, thereby improving the noise test accuracy of the mobile phone button.

[0029] Working principle: When in use, first switch the screw module 22 to drive the placement carrier 23 to slide along the support frame 21 and extend it. After extending it, the mobile phone to be tested is placed in the interior of the placement carrier 23 for clamping, and then switch the screw module 22 to drive the placement carrier 23 to reset. After placement, the buttons of the mobile phone to be tested are pressed by the button pressing mechanism 3. When the button pressing mechanism 3 is implemented, the buttons are pressed by the pressing component 32 on the surface of the support seat 31. During the pressing process, the noise generated by the movement of the pressing component 32 itself will be isolated by the sound insulation box 33, and noise will occur after the pressing component 32 presses the buttons of the mobile phone to be tested.

[0030] Subsequently, the noise generated after the keys of the two key pressing mechanisms 3 are pressed is collected by the right collecting mechanism 4 and the left collecting mechanism 5. When the right collecting mechanism 4 is implemented, the position of the right adjusting frame 42 on the right supporting platform 41 is adjusted, and the right adjusting frame 42 and the right supporting platform 41 are fixed after adjustment, and the pressing noise of the right side key of the mobile phone to be tested is collected by the right microphone 43 on the surface of the right adjusting frame 42; and when the left collecting mechanism 5 is implemented, the Y-axis sliding module 52 is driven to move to a suitable position by the X-axis sliding module 51, and then the left adjusting frame 53 is driven to move by the Y-axis sliding module 52, and after the movement, the pressing noise of the left side key of the mobile phone to be tested is collected by the left microphone 54 on the surface of the left adjusting frame 53.

[0031] After the collection is completed, the placement carrier 23 is driven to slide and extend along the support frame 21 by switching the screw module 22, and then the tested mobile phone is manually removed, and then the next mobile phone to be tested is switched and placed in, and the cycle is repeated in sequence to finally complete the use of the test fixture for noise testing.
