[0037] Example 1

[0038] This embodiment sets a test point on the alignment mechanism that matches the earphone under test, and sets a clamping end on the lifting mechanism facing the test point. When the lifting mechanism moves to the alignment mechanism, the clamping end abuts against the test point, thereby quickly and accurately achieving precise alignment between the test point and the earphone under test. This significantly shortens the testing time and improves the accuracy and efficiency of the test. The specific solution is as follows:

[0039] A headphone testing device includes a main body 1, a lifting mechanism 2, an alignment mechanism 3, and a testing mechanism 4. The main body 1 is provided with the lifting mechanism 2, the alignment mechanism 3, and the testing mechanism 4. The alignment mechanism 3 is electrically connected to the testing mechanism 4.

[0040] The alignment mechanism 3 is provided with at least one test point 321 that matches the earphone under test, and the lifting mechanism 2 is provided with a clamping end 271 facing the test point 321. In practical applications, the main body of the earphone under test is placed on the testing mechanism 4, and the part of the earphone under test extends between the lifting mechanism 2 and the alignment mechanism 3. When the lifting mechanism 2 descends toward the alignment mechanism 3, the clamping end 271 abuts against the part of the earphone under test, thereby achieving the alignment of the test point 321 with the part of the earphone under test.

[0041] Both the alignment mechanism 3 and the testing mechanism 4 are equipped with signal transmission modules.

[0042] As attached Figure 1 and attached Figure 2As shown, the main body 1 of the device serves as the support platform for the entire system, cleverly integrating a lifting mechanism 2, an alignment mechanism 3, and a testing mechanism 4. These three mechanisms work together to test the performance of the headphones. The electrical connection between the alignment mechanism 3 and the testing mechanism 4 ensures the accurate transmission and processing of test data.

[0043] The alignment mechanism 3 has test points 321 that match the earphone under test. In practical applications, the main body of the earphone under test is placed on the testing mechanism 4. The part of the earphone under test that is to be tested extends between the lifting mechanism 2 and the alignment mechanism 3 and is placed on the part of the alignment mechanism 3 where the test points 321 are arranged. When the lifting mechanism 2 descends toward the alignment mechanism 3, the clamping end 271 abuts against the part of the earphone under test, thereby aligning the test points 321 with the part of the earphone under test. This allows the test points 321 to accurately match the earphone's interface or a specific test area. In addition, the lifting mechanism 2 is equipped with a clamping end 271 facing the test points 321. When the lifting mechanism 2 is running, the clamping end 271 switches between being close to or far from the test points 321. When the lifting mechanism 2 descends toward the alignment mechanism 3, the clamping end 271 abuts against the part of the earphone under test, thereby aligning the test points 321 with the part of the earphone under test. This greatly shortens the testing time and lays a solid foundation for subsequent testing.

[0044] Furthermore, to enhance the testing efficiency and intelligence of the equipment, both the alignment mechanism 3 and the testing mechanism 4 have built-in signal transmission modules. These modules are responsible for transmitting test signals at high speed and stably during the testing process, and also ensure real-time feedback and analysis of test results, thereby greatly improving the accuracy and efficiency of the test.

[0045] In one specific embodiment, the alignment mechanism 3 includes a fixed part 31, a movable part 32 and a pin part 33. The fixed part 31 is disposed on the main body 1 of the device, and the side of the fixed part 31 near the lifting mechanism 2 is movably connected to the movable part 32.

[0046] The ejector pin 33 is disposed in the fixed part 31; the movable part 32 is provided with a test point 321, and the movable part 32 is provided with an ejector pin hole 322 for penetrating the ejector pin 33; in this embodiment, the movable part 32 is movably connected to the fixed part 31. When the lifting mechanism 2 descends toward the alignment mechanism 3 to abut the movable part 32, it will stop the movable part 32 from descending further, so that when the movable part 32 abuts the fixed part 31 under the drive of the lifting mechanism 2, the ejector pin 33 is aligned with the earphone under test through the ejector pin hole 322.

[0047] As attached Figure 3As shown, the fixed part 31 is securely mounted on the main body 1 of the equipment, ensuring the overall stability of the alignment mechanism 3 and providing a reliable mounting base for other components. The side of the fixed part 31 closest to the lifting mechanism 2 is movably connected to the movable part 32, allowing the movable part 32 to move flexibly as needed to adapt to different testing requirements.

[0048] The ejector pin 33, a key element in the alignment process, is located inside the fixed part 31. The movable part 32 not only has test points 321 that match the earphone under test, but also ejector pin holes 322. In practical applications, the earphone under test is placed on the testing mechanism 4. The part of the earphone under test extends between the lifting mechanism 2 and the alignment mechanism 3 and is placed on the part of the alignment mechanism 3 where the test points 321 are located. The part of the alignment mechanism 3 with the test points 321 has ejector pin holes 322. When the lifting mechanism 2 moves to abut against the alignment mechanism 3, it presses the movable part 32 against the part of the fixed part 31 where the ejector pin 33 is located. The ejector pin 33 passes through the ejector pin holes 322 on the movable part 32, achieving precise alignment of the part of the earphone under test. This improves testing accuracy and greatly simplifies the testing process, making the entire testing process more efficient and convenient.

[0049] In one specific embodiment, the alignment mechanism 3 further includes an elastic part 34; one end of the elastic part 34 is disposed in the fixed part 31, and the other end is connected to the movable part 32, so that when the lifting mechanism 2 abuts against the movable part 32, the movable part 32 is squeezed to abut against the fixed part 31; when the lifting mechanism 2 separates from the movable part 32, the movable part 32 is reset.

[0050] In practical applications, when the lifting mechanism 2 moves to contact the movable part 32, it will apply pressure to push the movable part 32 toward the fixed part 31 until the two contact. During this process, the elastic part 34 plays the role of transmitting and buffering pressure. After the lifting mechanism 2 completes its operation and separates from the movable part 32, the elastic part 34 uses its own elastic restoring force to help the movable part 32 quickly and accurately return to its initial position, which improves the flexibility and response speed of the alignment mechanism 3 and ensures the stability and reliability of the alignment mechanism 3 in operation.

[0051] In one specific embodiment, the lifting mechanism 2 includes a fixing member 21, a handheld member 22, a connecting member 23, and a connecting rod 24; the fixing member 21 is connected to the main body of the equipment 1;

[0052] The handheld component 22 is rotatably connected to the connecting component 23 and the fixing component 21 respectively. The end of the connecting component 23 away from the handheld component 22 is rotatably connected to the connecting rod 24. The end of the connecting rod 24 away from the connecting component 23 is provided with a clamping end 271. When an external force is applied to the handheld component 22, the handheld component 22 rotates relative to the fixing component 21, which drives the connecting component 23 to rotate relative to the handheld component 22 and the connecting rod 24 respectively. This causes the connecting rod 24 to move closer to or away from the alignment mechanism 3, thereby enabling the clamping end 271 (located at the lower part of the connecting rod 24) to move closer to or away from the alignment mechanism 3.

[0053] As attached Figure 4 As shown, the fixing component 21, serving as the foundation of the entire lifting mechanism, is installed on the main body 1 of the equipment, providing support and fixation. The handheld component 22 is ergonomic and easy to grip, and is the main component for user operation; simultaneously, the handheld component 22 is rotatably connected to both the connecting component 23 and the fixing component 21; the end of the connecting component 23 furthest from the handheld component 22 is also rotatably connected to the connecting rod 24, allowing the connecting rod 24 to be flexibly adjusted in angle under the action of the connecting component 23. The other end of the connecting rod 24 is provided with a clamping end 271.

[0054] As attached Figure 4 As shown, when an external force is applied to the handheld component 22, the handheld component 22 will rotate relative to the fixed component 21 due to the rotatable connection between the handheld component 22 and the fixed component 21. Simultaneously, due to the rotatable connection between the handheld component 22 and the connecting component 23, the rotation of the handheld component 22 under external force will also cause the connecting component 23 to move up and down. The up and down movement of the connecting component 23 will cause the connecting rod 24 to rise and fall. The lower part of the connecting rod 24 is provided with a clamping end 271. The rising and falling of the connecting rod 24 will cause the clamping end 271 to move closer to or further away from the alignment mechanism 3, thereby completing the positioning or release of the earphone to be tested. This improves the flexibility and practicality of the lifting mechanism 2, and also greatly enhances the overall ease of operation and work efficiency of the device.

[0055] In one specific embodiment, the lifting mechanism 2 further includes a guide 25, a stabilizer 26, and a pressing member 27. The guide 25 is disposed on the main body 1 of the equipment. One end of the stabilizer 26 is movably connected to the guide 25, and the other end is connected to the end of the connecting rod 24 away from the connecting member 23.

[0056] The pressing member 27 is connected to the side of the stabilizing member 26 away from the connecting rod 24, and the pressing member 27 is provided with a clamping end 271 on the side away from the stabilizing member 26.

[0057] As attached Figure 5As shown, the guide member 25 is mounted on the main body 1 of the equipment, providing stable guidance for the entire lifting mechanism 2 and ensuring the accuracy and stability of the lifting mechanism 2 during operation. One end of the stabilizer 26 is movably connected to the guide member 25, allowing the stabilizer 26 to move flexibly and stably under the guidance of the guide member 25. The other end of the stabilizer 26 is tightly connected to the end of the connecting rod 24 away from the connecting member 23, enhancing the stability of the connecting rod 24.

[0058] The pressing component 27 is connected to the side of the stabilizing component 26 away from the connecting rod 24, and a clamping end 271 is provided on the side of the pressing component 27 away from the stabilizing component 26. In practical applications, the shape and size of the clamping end 271 can be adjusted according to actual needs to achieve precise positioning of the target object.

[0059] When the lifting mechanism 2 is in operation, the rotation of the handheld component 22 will drive the connecting component 23 and the connecting rod 24 to perform corresponding actions, which will then be transmitted to the pressing component 27 through the stabilizing component 26. Under the guidance of the stabilizing component 26, the pressing component 27 will align or release the earphone to be tested through the clamping end 271, thereby improving the overall ease of operation and work efficiency of the device.

[0060] In one specific embodiment, the testing mechanism 4 includes a testing component 41 and a fixing component 42. The testing component 41 is disposed on the device body 1, and the fixing component 42 is disposed at the end of the testing component 41 away from the device body 1. The fixing component 42 is electrically connected to the testing component 41.

[0061] In practical applications, the headphone testing equipment of this embodiment is used in conjunction with an external testing instrument. The external testing instrument first transmits various test commands and data to the alignment mechanism 3. The alignment mechanism 3 aligns the headphone to be tested according to the commands and transmits the commands and data to the testing component 41. The testing component 41 performs precise testing operations on the headphone to be tested according to the commands and then transmits the test data to the external instrument.

[0062] In this embodiment, the test component 41 is a 711 simulated ear. The 711 simulated human ear utilizes advanced acoustic technology and materials, accurately reproducing the frequency response, sound pressure level, and sound conduction characteristics of the human ear. It can simulate the sound reception characteristics of the human ear at different frequencies, ensuring the authenticity of the test results. In practical applications, different test components can be selected according to actual needs to adapt to diverse testing requirements.

[0063] The fixing component 42 is located at the end of the test component 41 away from the main body 1 of the device. It is used to fix the earphone under test to prevent it from shaking or shifting during the test. It also ensures that the test component 41 and the test object can maintain good contact, thereby improving the accuracy and reliability of the test.

[0064] In one specific embodiment, the main body of the equipment 1 includes a test platform 11 and a column 12. The column 12, the alignment mechanism 3 and the test mechanism 4 are all disposed on the test platform 11. The end of the column 12 away from the test platform 11 is connected to the lifting mechanism 2.

[0065] In one specific embodiment, a trigger button 5 is also included. The trigger button 5 is disposed on the main body 1 of the device and is electrically connected to the test mechanism 4. When the user presses the trigger button 5, the test mechanism 4 can be started accurately and quickly to realize the test operation.

[0066] In one specific embodiment, the signal transmission module includes a wireless communication module.

[0067] In practical applications, the headphone testing equipment of this embodiment is used in conjunction with an external testing instrument. The external testing instrument first transmits various test commands and data to the alignment mechanism 3. The alignment mechanism 3 aligns the headphone under test according to the commands and transmits the commands and data to the testing component 41. The testing component 41 performs precise test operations on the headphone under test according to the commands and then transmits the test data to the external instrument. Through the wireless communication module, the alignment mechanism 3 and the testing component 41 can realize data transmission and communication with the external testing instrument, which greatly improves the flexibility and convenience of the equipment.
