[0030] Among them: the audio testing mechanism and the test station 20 are both located on the machine 10, the test station 20 is used to fix the headphones to be tested, and different models of headphones to be tested need to use corresponding headphone test fixtures to be connected to the test station 20, so that the TWS headphone audio testing system can perform audio tests on multiple models of headphones to be tested. It should be noted that an installation mechanism is provided on the test station 20, and the headphone test fixture is detachably connected to the test station 20 through the installation mechanism. Furthermore, the headphone test fixture is detachably connected to the installation mechanism.

[0031] It should be noted that there are two test stations 20 so that when audio testing is being performed on one of the test stations 20 , materials can be loaded on the other test station 20 , thereby realizing alternating testing and reducing loading time.

[0032] In this embodiment, the audio testing mechanism is used to perform audio testing on the headphones to be tested. Specifically, the audio testing mechanism includes an electroacoustic tester, a microphone and an artificial ear. The microphone and the artificial ear are both located on the test station 20.

The microphone and the artificial ear are respectively connected to the electroacoustic tester, and the electroacoustic tester is used to connect different test circuits to realize the audio test operation of the headphones to be tested.

[0033] In this embodiment, a shielding box 21 is provided on the test station 20, and a lifting structure is provided on the machine 10. The shielding box 21 and the lifting structure, the shielding box 21 are located above the earphones to be tested, and the lifting structure is used to drive the shielding box 21 to reciprocate in the vertical direction. It should be noted that the lifting structure includes a driving cylinder 23, the piston rod of the driving cylinder 23 is connected to the shielding box 21, the piston rod is perpendicular to the table top of the machine 10, and the extension direction of the piston rod is parallel to the vertical direction. The shielding box 21 is driven to move in the vertical direction by the driving cylinder 23 to make the shielding box 21 move away from or close to the test station 20.

[0034] It should be noted that the internal hollow space of the shielding box 21 forms a accommodating space, and the shielding box 21 is driven to move toward the test station 20 by driving the cylinder 23, so that the shielding box 21 covers the test station 20, so that the microphone, artificial ear and the headphone test fixture with the headphone to be tested are all located in the accommodating space, so that when the audio test is performed on the headphone to be tested subsequently, the test station 20 can be isolated from the external environment, which is conducive to reducing the degree of interference with the test process, thereby improving the test accuracy.

[0035] In this embodiment, the front of the shielding box 21 is composed of two layers of glass plates, and a gap is provided between the two layers of glass plates. The gap is vacuum treated to form a vacuum space to improve the anti-interference ability of the shielding box 21. At the same time, the glass plates are made of transparent material. Through the above setting, it is convenient for the staff to observe whether the headphones to be tested in the shielding box 21 are displaced or detached from the headphone test fixture.

[0036] In this embodiment, the lifting structure also includes a moving part for guiding the movement of the shielding box 21. Specifically, the moving part includes a slide rail 22 and a slider.

The mounting structure includes a pad 34, a clamping plate 35 and a pressure rod 36. A mounting groove 32 is provided on the mounting plate 31 of the test station 20. The pad 34 is connected to the bottom of the mounting groove 32 through an elastic support member. The elastic support member is a telescopic spring 33, that is, one end of the telescopic spring 33 is connected to the bottom of the pad 34, and the other end of the telescopic spring 33 is connected to the bottom of the mounting groove 32. The pressure rod 36 is connected to the side wall of the pad 34. The pressure plate is an L-shaped structure. The pressure rod 36 is connected to the clamping plate 35 through a connecting rod 37, wherein one end of the connecting rod 37 is hinged to the middle of the clamping plate 35, and the other end of the connecting rod 37 is hinged to the middle of the pressure rod 36.

[0041] In this embodiment, the guide structure includes a guide block 41, a guide groove 42 is opened on the top of the pad 34, the guide block 41 is embedded in the guide groove 42, the guide block 41 is connected to the splint 35, the cross-section of the guide block 41 is a trapezoidal structure, and the inner cavity of the guide groove 42 is adapted to the guide block 41.

[0042] It should be noted that a through groove is provided on the mounting plate 31, which is connected to the mounting groove 32. Part of the connecting rod 37 is located in the through groove, and part of the pressure plate is located in the through groove, and the other part of the pressure plate is located on the outside of the machine 10 so that the pressure plate has a certain amount of space for movement. In addition, a baffle 38 is provided on the machine 10, which covers part of the opening of the mounting groove 32. The baffle 38 and the clamping plate 35 are respectively located on the opposite sides of the mounting groove 32.

[0043] It should be noted that when the headphone test fixture is fixed, the pressure plate is pressed, and the pressure plate drives the pad 34 to move downward, the telescopic spring 33 is compressed, and the clamp 35 moves in the direction away from the baffle 38 until the clamp 35 reaches the preset position. At this time, the headphone test fixture is placed on the pad 34, and one end of the headphone test fixture is gently pushed to the bottom of the baffle 38, and then the pressure plate is released. The pressure plate and the pad 34 move upward under the action of the telescopic spring 33, and the clamp 35 moves toward the baffle 38 as the pressure plate moves upward until it abuts against the end of the headphone test fixture away from the baffle 38, thereby limiting the headphone test fixture.

[0044] In the specific implementation, at least two test stations 20 are set on the machine 10, so that when audio testing is performed on one of the test stations 20, materials are loaded on the other test station 20, thereby realizing alternating testing and reducing loading time, which is beneficial to improving the overall test speed and reducing testing costs. At the same time, by installing a structural headphone test fixture and detachably connecting it to the test station 20, when testing different types of TWS headphones, the corresponding headphone test fixture can be used to connect it to the test station 20, and then the corresponding TWS headphones can be subjected to audio testing, so that the TWS headphone audio testing system can adapt to various models of TWS headphones, further reducing the testing cost.
