[0030] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0031] like Figure 1-12 As shown, an automated testing production line for laptops includes a barcode scanning station 100, a speaker testing device 200, a fan noise testing device 300, and a microphone testing device 400 arranged sequentially along the product flow direction. The barcode scanning station 100 is equipped with a first conveyor line 11, the speaker testing device 200 is equipped with a second conveyor line 21, the speaker testing device 200 and the fan noise testing device 300 are connected by a third conveyor line 500, the fan noise testing device 300 is equipped with a fourth conveyor line 31, the fan noise testing device 300 and the microphone testing device 400 are connected by a fifth conveyor line 600, and the microphone testing device 400 is equipped with a sixth conveyor line 41. The first conveyor line 11, the second conveyor line 21, the third conveyor line 500, the fourth conveyor line 31, the fifth conveyor line 600, and the sixth conveyor line 41 are connected end to end in sequence. During processing, the laptop computer to be tested can be conveyed through the first conveyor line 11 to the second conveyor line 21, and then sequentially flow into the third conveyor line 500, the fourth conveyor line 31, the fifth conveyor line 600 and the sixth conveyor line 41.

[0032] The barcode scanning connection station 100 is used to calibrate the opening and closing positions of the laptops, ensuring that each laptop can be opened to a fixed angle before testing, thus improving test consistency. In this embodiment, during testing, after scanning the barcode connection station 100, each laptop can be opened to 90°. In other embodiments, any other opening angle can be used for testing. The barcode scanning connection station 100 can also scan the laptop's code, connecting the laptop to the control center so that the control center can control the laptop to perform testing. Simultaneously, the barcode scanning connection station 100 can also send the scanned laptop onto the second conveyor line 21. Typically, test programs are pre-installed on the laptops. After scanning the code and connecting to the control center, the control center can control the laptop to run the corresponding test program, thereby realizing the testing process. In this embodiment, after the barcode scanning connection station 100 scans the laptop's code, the laptop can communicate with the control center via Wi-Fi.

[0033] The speaker testing device 200 is used to test the speaker performance and keyboard resonance performance of a laptop computer, and can send the tested laptop computer to the third conveyor line 500. The fan noise testing device 300 is used to test the noise level of the laptop computer's cooling fan, and can send the tested laptop computer to the fifth conveyor line 600. The microphone testing device 400 has a receiving component 700 on the side away from the fifth conveyor line 600. The receiving component 700 is connected to the sixth conveyor line 41, which can send the tested laptop computer to the receiving component 700 for collection. The microphone testing device 400 is used to test the microphone performance and airtightness of a laptop computer, and can send the tested laptop computer to the receiving component 700.

[0034] During operation, the host computer or a technician places the laptop to be tested onto the first conveyor line 11, controls the barcode scanning station 100 to calibrate the laptop's position and opening angle, and scans the identification code on the laptop, connecting the laptop on the first conveyor line 11 to the control center of the production line. The laptop is then conveyed via the first conveyor line 11 to the second conveyor line 21, where the speaker testing device 200 is controlled to test the laptop's speaker performance and keyboard resonance performance. Finally, the laptop is conveyed via the second conveyor line 21 to the third conveyor line 500, where the third conveyor line 500 is controlled to... The laptop is conveyed to the fourth conveyor line 31; then the fan noise testing device 300 is controlled to operate and detect the fan noise of the laptop during operation; after the test, the laptop is conveyed to the fifth conveyor line 600 via the fourth conveyor line 31, and then to the sixth conveyor line 41 via the fifth conveyor line 600; then the microphone testing device 400 is controlled to operate and test the microphone performance and airtightness of the laptop; after the test, the laptop is sent to the receiving assembly 700 via the sixth conveyor line 41 to complete the entire testing process; the operator or robot arm then takes the tested laptop out of the receiving assembly 700 to complete the unloading.

[0035] This automated testing pipeline for laptops employs a streamlined workflow, connecting multiple devices for collaborative operation. It eliminates the need for manual transport of laptops and can simultaneously perform tests on speaker performance, keyboard resonance performance, cooling fan noise, microphone performance, and microphone airtightness. By replacing manual labor with machines, it reduces labor costs and significantly improves testing efficiency.

[0036] To improve the accuracy of the test structure, in this embodiment, the speaker test device 200, the fan noise test device 300, and the microphone test device 400 are all equipped with protective covers 80. The protective covers 80 can reduce the entry of external noise, so that the test environment is in a relatively quiet scene, so as to test the microphone, speaker and cooling fan of the laptop and improve the accuracy of the test.

[0037] like Figure 3 , Figure 5 , Figure 6 As shown, for ease of operation, material passage notches 81 are provided on both the left and right sides of the protective cover 80. These notches 81 are positioned at corresponding locations on the corresponding conveyor lines. For example, on the speaker testing equipment 200, the material passage notch 81 is positioned at the corresponding location on the second conveyor line 21. The material passage notches 81 allow the laptop computer being tested to pass through, enabling the laptop to move between different devices. An opening / closing mechanism 82 is provided on the protective cover 80 at a position corresponding to the material passage notch 81. The opening / closing mechanism 82 is used to open or close the material passage notch 81.

[0038] Specifically, the opening and closing mechanism 82 includes an opening and closing mounting plate 821, which is fixedly connected to the protective cover 80. An opening and closing cylinder 822 is provided on the opening and closing mounting plate 821, and an opening and closing block 823 is provided on the output end of the opening and closing cylinder 822. The opening and closing cylinder 822 can drive the opening and closing block 823 to move so that the opening and closing block 823 opens or closes the material passage gap 81.

[0039] In this embodiment, the material feeding notch 81 is right-angled, and the shape of the opening block is adapted to the material feeding notch 81; the opening and closing cylinder 822 is inclined at a 45° angle on the protective cover 80. Inclining the opening and closing cylinder 822 at a 45° angle can minimize the cylinder stroke, thereby improving processing efficiency; it can also reduce the size of the opening and closing cylinder 822 and save manufacturing costs.

[0040] like Figure 4As shown, the barcode scanning station 100 includes a first base 12, a first conveyor line 11 mounted on the first base 12, a positioning frame 13 and a push cylinder 14 on the first base 12. One end of the positioning frame 13 extends into the first conveyor line 11, and a push block 15 is provided on the output end of the push cylinder 14. The push block 15 is used to push the laptop computer to slide laterally on the first conveyor line 11. During processing, the host computer or a robotic arm places the laptop computer on the first conveyor line 11, drives the laptop computer to move to the corresponding position on the positioning frame 13 through the first conveyor line 11, and then controls the push cylinder 14 to push the laptop computer to slide laterally on the first conveyor line 11 until the side of the laptop computer away from the push block 15 abuts against the positioning frame 13. Through the cooperation of the push cylinder 14 and the positioning frame 13, the position of each laptop computer is consistent during testing, improving the accuracy and stability of the test.

[0041] A flip cylinder 16 is mounted on the positioning frame 13. A suction cup mounting plate 17 is provided on the output end of the flip cylinder 16. Multiple negative pressure suction cups 18 are mounted on the suction cup mounting plate 17. Each negative pressure suction cup 18 is externally connected to a negative pressure device that generates negative pressure suction to abut against the back of the laptop. The flip cylinder 16 is used to drive the laptop screen to flip open. During processing, after the pushing cylinder 14 completes its operation, both sides of the laptop abut against the pushing block 15 and the positioning frame 13, respectively. Then, the flip cylinder 16 is controlled to operate, driving the negative pressure suction cups 18 to move closer to the laptop until they abut against the back of the laptop screen, where they adhere to the screen. The flip cylinder 16 is then controlled to reset, driving the negative pressure suction cups 18 to move away from the laptop, causing them to pull the laptop screen to rotate relative to the keyboard until the flip cylinder 16 has reset. Finally, the negative pressure device connected to the negative pressure suction cups 18 stops the negative pressure suction. The flip cylinder 16 and negative pressure suction cup 18 can flip the laptop open to a fixed angle, so that each laptop can be opened to a fixed angle before testing, improving the accuracy and stability of the test.

[0042] A scanning dock 19 is provided on the side of the first base 12 near the push cylinder 14. The scanning dock 19 is used to identify the identification code on the laptop computer on the first conveyor line 11. Before testing, the laptop computer displays a QR code on its screen. During the actual processing, when the negative pressure suction cup 18 opens the laptop computer to a suitable angle, the scanning dock 19 can scan the QR code on the screen, thereby establishing a connection between the laptop computer and the control center of the testing line, so that the control center can control the laptop computer to perform testing. After the scanning dock 19 completes scanning, it controls the push cylinder 14 to reset, drives the push block 15 to move away from the laptop computer, so that the push block 15 disengages from the laptop computer; then it controls the first conveyor line 11 to work, sending the laptop computer through the material feeding notch 81 into the second conveyor line 21.

[0043] like Figure 6 As shown, the speaker testing equipment 200 includes a second base 22, and a second conveyor line 21 is fixedly mounted on the second base 22. The second conveyor line 21 is equipped with a first blocking component 23 and a first clamping and positioning component 24. The first blocking component 23 is used to limit the laptop computer to a specific position on the second conveyor line 21, ensuring that each laptop computer can stay at a uniform position on the second conveyor line 21, thus improving the consistency of the test. The first clamping and positioning component 24 is used to hold the laptop computer against both sides, fixing it in place on the second conveyor line 21 to test the speaker and keyboard resonance of the laptop computer, improving the stability and accuracy of the test. The second base 22 is equipped with a sound pickup component 25, which is used to pick up the sound played by the speaker of the laptop computer or the vibration sound of the keyboard when the laptop computer is working. During the test, the control center controls the laptop computer on the second conveyor line 21 to play an audio file, and the sound pickup component 25 can pick up the corresponding sound to determine whether the speaker performance and keyboard resonance of the laptop computer are qualified.

[0044] To improve the accuracy of the test, a background noise pickup microphone 26 is also provided on the second base 22. The background noise pickup microphone 26 is located on the side of the second base 22 away from the second conveyor line 21. The background noise pickup microphone 26 is used to pick up the background noise inside the protective cover 80 of the speaker test equipment 200 and feed the background noise information back to the control center. The control center uses software algorithms to eliminate the background noise from the sound picked up by the pickup component 25, which is then the sound played by the speaker or the resonance sound of the keyboard. By obtaining and canceling the background noise, the accuracy of the test can be improved.

[0045] Specifically, such as Figure 7As shown, the second conveyor line 21 includes two parallel conveyor frames 211 connected to the second base 22. Each conveyor frame 211 has a conveyor belt 212. The second base 22 has a conveyor drive assembly 213 for driving the conveyor belts 212. The conveyor drive assembly 213 is a motor-pulley structure. The motor drives the pulley to rotate, thereby driving the conveyor belts 212 to move on the conveyor frames 211, thus achieving the purpose of driving the laptop computer to move. The second base 22 also has a conveyor adjustment mechanism 214 for adjusting the distance between the two conveyor frames 211. The conveyor adjustment mechanism 214 is a motor-screw structure. By controlling the motor to drive the screw to rotate, it drives one of the conveyor frames 211 to move closer to or further away from the other conveyor frame 211, changing the distance between the two conveyor frames 211. This allows the distance between the two conveyor belts 212 to change synchronously, making it suitable for testing laptops of different sizes.

[0046] To accommodate the testing needs of laptops of different sizes, a blocking adjustment mechanism 27 is installed on the conveyor frame 211 to adjust the position of the first blocking component 23. The blocking adjustment mechanism 27 is a motor screw structure. The first blocking component 23 is installed on the output end of the blocking adjustment mechanism 27. By controlling the motor to work, the first blocking component 23 can be driven to move on the conveyor frame 211 in a direction parallel to the movement direction of the conveyor belt 212. This allows the first blocking component 23 to block laptops of different sizes on the conveyor belt 212 at the position aligned with the sound pickup component 25, so that the sound pickup component 25 can test the speaker performance and keyboard resonance of the laptop.

[0047] The first blocking component 23 includes a blocking cylinder 231, which is mounted on the output end of the blocking adjustment mechanism 27. A blocking block 232 is provided on the output end of the blocking cylinder 231. The blocking cylinder 231 can drive the blocking block 232 to move in a direction perpendicular to the movement direction of the conveyor belt 212, causing the blocking block 232 to extend into or out of the conveyor belt 212. Normally, the blocking cylinder 231 extends, causing the blocking block 232 to extend into the conveyor belt 212. During operation, the conveyor belt 212 moves the laptop. When the laptop moves to the corresponding position of the blocking block 232, the blocking block 232 abuts against one end of the laptop, preventing the conveyor belt 212 from moving the laptop further. At this point, the laptop is positioned opposite the microphone assembly 25. After the microphone assembly 25 has been tested, the blocking cylinder 231 is retracted, driving the blocking block 232 to disengage from the laptop. Then, the conveyor belt 212 can move the laptop and transport it to the third conveyor line 500.

[0048] The first clamping and positioning assembly 24 includes clamping cylinders 241 symmetrically distributed on two conveyor frames 211, one of which is installed on each conveyor frame 211, and the two clamping cylinders 241 are arranged opposite to each other. Clamping blocks 242 are respectively provided on the output end of the clamping cylinders 241. During testing, after the blocking block 232 blocks the laptop, the control conveyor belt 212 stops working; then the two clamping cylinders 241 are controlled to work, driving the clamping blocks 242 to move closer to the conveyor belt 212 until the two clamping blocks 242 respectively abut against the two sides of the laptop, clamping the laptop so that it can no longer move; then the laptop's speakers are controlled to play audio, and then the speaker performance and keyboard resonance performance of the laptop are tested through the cooperation of the sound pickup component 25 and the low-noise pickup microphone 26; after the test is completed, the control clamping cylinder 241 is reset, and the blocking cylinder 231 is controlled to retract, so that the blocking block 232 and the two clamping blocks 242 are respectively detached from the laptop; then the laptop is transported to the third conveyor line 500 by the conveyor belt 212.

[0049] like Figure 8 As shown, the sound pickup assembly 25 includes a first sound pickup mechanism 251, a second sound pickup mechanism 252, and a third sound pickup mechanism 253. The first sound pickup mechanism 251 and the second sound pickup mechanism 252 are respectively disposed above the second conveyor line 21, and the third sound pickup mechanism 253 is disposed below the second conveyor line 21. Depending on the speaker placement of different types of laptops, the first sound pickup mechanism 251, the second sound pickup mechanism 252, or the third sound pickup mechanism 253 can be freely used, or they can be used simultaneously or partially. This utility model does not limit this.

[0050] The first pickup mechanism 251, the second pickup mechanism 252, and the third pickup mechanism 253 have the same structure. This article will use the third pickup mechanism 253 as an example.

[0051] Specifically, such as Figure 9 As shown, the third pickup mechanism 253 includes a vertical drive module 2531, which is connected to the second base 22. A horizontal drive module 2532 is located at the output end of the vertical drive module 2531, and a microphone mounting block 2533 is located at the output end of the horizontal drive module 2532. A pickup microphone 2534 is mounted on the microphone mounting block 2533. In actual operation, since the speaker positions of various laptop models differ, the vertical drive module 2531 drives the horizontal drive module 2532 and the pickup microphone 2534 to move vertically, and the horizontal drive module 2532 drives the pickup microphone 2534 to move horizontally. This allows the pickup microphone 2534 to move freely in a two-dimensional plane, making it suitable for testing different types of laptops.

[0052] Both the transverse drive module 2532 and the longitudinal drive module 2531 are motor lead screw structures, and their specific structures will not be described in detail in this article.

[0053] In this embodiment, the horizontal drive module 2532 is equipped with two microphones 2534. The lead screw on the horizontal drive module 2532 is a bidirectional lead screw, which can drive the two microphones 2534 to move closer together or further apart. Since many laptops have two symmetrically arranged speakers, setting up two microphones 2534 can simultaneously pick up the sound from both speakers, thereby improving the accuracy and convenience of testing.

[0054] The third conveyor line 500 is fixedly connected to the speaker testing device 200 and the fan noise testing device 300, respectively. The fifth conveyor line 600 is fixedly connected to the fan noise testing device 300 and the microphone testing device 400, respectively. Both the third conveyor line 500 and the fifth conveyor line 600 are structures in which the motor pulley drives the belt to rotate. Their structures will not be described in detail here. In other embodiments, any existing structure or device that can drive the linear movement of a laptop computer can also be used.

[0055] The structure of the fan noise testing device 300 is the same as that of the speaker testing device 200, and the specific structure of the fan noise testing device 300 will not be described in detail here. During fan noise testing, the control center of the production line controls the laptop to operate normally. Through the cooperation of the microphone 2534 and the background noise microphone 26, and through the software algorithm of the control center, the fan noise of the laptop during operation can be obtained, thereby determining whether the fan noise of the laptop is within the acceptable range, thus realizing the fan noise testing process for the laptop.

[0056] like Figure 10 As shown, the microphone testing device 400 includes a third base 42, and a sixth conveyor line 41 is fixedly mounted on the third base 42. The sixth conveyor line 41 has the same structure as the second conveyor line 21, so its structure will not be described in detail here. A second blocking component 43 and a second clamping and positioning assembly 44 are mounted on the sixth conveyor line 41. The second blocking component 43 is used to limit the laptop computer to the sixth conveyor line 41, ensuring that each laptop computer can stay at a uniform position on the sixth conveyor line 41, thus improving the consistency of the test. The second blocking component 43 has the same structure as the first blocking component 23, so its structure will be described in detail here. The second clamping and positioning assembly 44 is used to hold the laptop computer against both sides to test the microphone performance and airtightness of the laptop computer, improving the stability and accuracy of the test.

[0057] The second clamping and positioning assembly 44 is similar in structure to the first clamping and positioning component 24, except that the second clamping component has three clamping cylinders 241, which are arranged in a triangle on both sides of the sixth conveyor line 41. During operation, the three clamping cylinders 241 work simultaneously to drive the corresponding clamping blocks 242 to move. The three clamping blocks 242 then press against both sides of the laptop computer, thereby fixing the laptop computer on the sixth conveyor line 41.

[0058] The third mounting base 42 is equipped with a first speaker 45 and a second speaker 46. The first speaker 45 is positioned directly above the sixth conveyor line 41, and the second speaker 46 is positioned at an angle to the upper side of the sixth conveyor line 41. Depending on the microphone installation position of the test laptop, the first speaker 45 and / or the second speaker 46 can be controlled to play audio, thereby enabling the laptop on the sixth conveyor line 41 to pick up the corresponding sound in order to test whether the laptop's microphone performance is normal.

[0059] The third base 42 is also equipped with a first hole-blocking mechanism 47 and a second hole-blocking mechanism 48. The first hole-blocking mechanism 47 is located above the sixth conveyor line 41, and the second hole-blocking mechanism 48 is located on one side of the sixth conveyor line 41. The first hole-blocking mechanism 47 and the second hole-blocking mechanism 48 are used to block the sound outlet of the laptop computer on the sixth conveyor line 41. Depending on the different microphone installation positions on different laptop computers, the first hole-blocking mechanism 47 or the second hole-blocking mechanism 48 can be controlled to block the sound outlet of the laptop computer, so as to test the airtightness of the microphone of the laptop computer on the sixth conveyor line 41.

[0060] During the specific test, the sixth conveyor line 41 transports the laptop to the corresponding position of the second blocking component 43, where it is blocked by the second blocking component 43 onto the sixth conveyor line 41. The laptop is then clamped and fixed in place by the second clamping and positioning assembly 44. Next, the first speaker 45 and / or the second speaker 46 play test audio. The microphone of the laptop on the sixth conveyor line 41 picks up the audio information and sends it back to the control center, which can then determine whether the laptop's microphone performance is normal. Then, the first hole-blocking mechanism 47 or the second hole-blocking mechanism 48 is activated to block the sound outlet of the laptop on the sixth conveyor line 41. The first speaker 45 and / or the second speaker 46 play test audio again, and the laptop's microphone picks up the audio information and sends it back to the control center. By comparing the data with and without the sound outlet blocked, the control center can determine whether the laptop's microphone airtightness is up to standard.

[0061] It should be noted that laptop microphones are mainly distributed in the following ways:

[0062] 1. The microphone is installed on the outer edge of the laptop screen, usually on the side of the laptop's camera.

[0063] 2. The microphone is installed below the built-in mouse of the laptop, usually inside the bottom shell of the laptop.

[0064] Normally, the first hole-blocking mechanism 47 is used to test the airtightness of the microphone of the first type of laptop computer; the second hole-blocking mechanism 48 is used to test the airtightness of the microphone of the second type of laptop computer.

[0065] like Figure 11 As shown, the first plugging mechanism 47 includes a plugging lifting module 471, which is fixedly mounted on the third base 42. The plugging lifting module 471 is a motor screw structure, and a gripper cylinder 472 is installed on the output end of the plugging lifting module 471. Two silicone grippers 473 are provided on the output end of the gripper cylinder 472. When testing the microphone airtightness of the first type of laptop computer, the plugging lifting module 471 is controlled to work, driving the gripper cylinder 472 to descend until the two silicone grippers 473 move to both sides of the laptop computer's microphone; then the gripper cylinder 472 is controlled to work, driving the two silicone grippers 473 to move closer together until the two silicone grippers 473 clamp the laptop computer, blocking the laptop computer's sound outlet. Then the first speaker 45 and / or the second speaker 46 are controlled to play test audio to test the microphone airtightness of the laptop computer. After the test is completed, first control the gripper cylinder 472 to work, driving the two silicone grippers 473 to separate; then control the hole-blocking lifting module 471 to reset, driving the silicone grippers 473 to rise and reset to the initial position.

[0066] like Figure 12As shown, to accommodate the processing needs of laptops of different sizes, a hole-blocking adjustment module 49 is provided on the third base 42 to drive the second hole-blocking mechanism 48 to move laterally. The hole-blocking adjustment module 49 can drive the second hole-blocking mechanism 48 to move laterally on the third base 42. The driving direction of the hole-blocking adjustment module 49 is perpendicular to the movement direction of the sixth conveyor belt 212. The structure of the hole-blocking adjustment module 49 is a motor screw structure, and its specific structure will not be described in detail here. The second hole-blocking mechanism 48 includes a hole-blocking mounting block 481, on which two hole-blocking cylinders 482 are provided. One hole-blocking cylinder 482 is horizontally arranged, and the other hole-blocking cylinder 482 is inclined. Because the shape of the laptop shell is different, if the laptop shell is a right-angle structure, the horizontally arranged hole-blocking cylinder 482 can be controlled to work; if the laptop shell is an angled structure, the inclined hole-blocking cylinder 482 can be controlled to work. Two plugging cylinders 482 are each fitted with a silicone plug 483 at their output ends. The plugging cylinders 482 can drive the corresponding silicone plug 483 to contact or separate from the laptop computer on the sixth conveyor line 41. Before testing the microphone airtightness of the second type of laptop computer, the plugging adjustment module 49 is controlled to drive the second plugging mechanism 48 to move laterally on the third base 42 until the second plugging mechanism 48 can connect with the laptop computer on the sixth conveyor line 41. During the test, the corresponding plugging cylinder 482 is controlled to operate, driving the silicone plug 483 to move, so that the silicone plug 483 contacts the sound outlet of the laptop computer on the sixth conveyor line 41, sealing the sound outlet. Then, the first speaker 45 and / or the second speaker 46 are controlled to play test audio to test the microphone airtightness of the laptop computer. After the test is completed, the plugging cylinder 482 is controlled to reset, driving the silicone plug 483 to leave the laptop computer and return to its initial position.

[0067] like Figure 2As shown, the receiving assembly 700 includes a receiving rack 71, which is fixedly connected to the third base 42. One end of the receiving rack 71 is connected to the discharge end of the sixth conveyor line 41. Multiple rotatable rollers 72 are mounted on the receiving rack 71, and baffles 73 are installed on the sides of the receiving rack 71. By setting the rollers 72, the laptops that have completed testing are fed onto the rollers 72 after being delivered from the third base 42 by the sixth conveyor line 41. The rotating rollers 72 reduce friction on the laptops, thus protecting their appearance. The baffles 73 prevent the laptops from falling out of the receiving rack 71, improving testing safety. After testing, the sixth conveyor line 41 delivers the tested products from the third base 42, which then flow onto the rollers 72. An operator or robotic arm then removes the laptops from the rollers 72, completing the unloading process. In other embodiments, the receiving component 700 can also be replaced by a conveyor belt, through which the tested products are directly fed into the conveyor belt via the sixth conveyor line 41, and then transported to the next workstation, thereby realizing an automated testing process without human intervention.

[0068] This automated testing pipeline for laptops can test laptops of different sizes and types, significantly improving the equipment's versatility. A single pipeline can meet the testing needs of most types of laptops currently on the market. Furthermore, this automated testing pipeline can simultaneously test the laptop's speaker performance, keyboard resonance, fan noise, microphone performance, and microphone airtightness, covering almost all current testing items for laptop audio performance. It is powerful, and the entire process is fully automated, requiring no human intervention. This high degree of automation saves significant manpower and improves testing efficiency.

The scope of this utility model includes but is not limited to the specific embodiments described above. All equivalent changes made in accordance with this utility model are within the protection scope of this utility model.
