When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such a combination of technical solutions does not exist and is not within the scope of protection required by the present invention.

[0028] The present invention proposes a headset function test device, please refer to Figure 1 The earphone function test device includes a rotating table 20, a workbench 10, a first driving component 30, a second driving component 40 and a signal detection module (not shown in the figure), wherein the workbench 10 is used to place the earphone to be tested, and the workbench 10 can be rotatably set on the rotating table 20; the first driving component 30 is used to drive the rotating table 20 to rotate around a first direction; the second driving component 40 is used to drive the workbench 10 to rotate around a second direction relative to the rotating table 20, and the first direction and the second direction are perpendicular to each other; the signal detection module is used to detect the working signal of the earphone to be tested.

[0029] In the production process of Bluetooth headsets, in order to ensure the quality of Bluetooth headsets, it is necessary to test the functions of Bluetooth headsets after they are produced. The headset to be tested in this embodiment can be a TWS (True Wireless Stereo) headset or a single-earbud Bluetooth headset. The headset to be tested in this embodiment takes a TWS headset as an example. The TWS headset has several sensors, such as a gravity sensor, which detects the gravity acceleration in various directions to determine whether the user is wearing the headset; or detects the user's skin through a color sensor to determine whether the user is wearing the headset, etc.

[0030] In this embodiment, the rotating table 20 can be directly suspended on the first driving assembly 30, or the rotating table 20 can be suspended on an external support structure and connected to the first driving assembly 30, so that the rotating table 20 is driven to rotate by the first driving assembly 30. The workbench 10 is arranged on the rotating table 20, so that the workbench 10 rotates simultaneously with the rotating table 20, that is, the first driving assembly 30 indirectly drives the workbench 10 to rotate around the first direction. A second driving assembly 40 is arranged on the side of the rotating table 20 away from the workbench 10, and a hollow structure is arranged on the rotating table 20, and the second driving assembly 40 is connected to the workbench 10 through the hollow structure, so that the workbench 10 is driven to rotate around the second direction on the rotating table 20 by the second driving assembly 40. Among them, the first direction is arranged perpendicular to the second direction, and the first driving component 30 and the second driving component 40 work together to simulate the movement trajectory of the user's head when wearing the headphones, that is, gravity acceleration is applied in all directions, so that the headphones to be tested are determined to be in a state where the user is wearing the headphones.

[0031] It should be noted that the earphone function testing device of the present invention includes but is not limited to the above-mentioned solution, and the second driving component 40 can also be arranged on other external support structures, as long as it can drive the workbench 10 to rotate around the second direction.

[0032] After the earphone to be tested is determined to be in the wearing state, the signal detection module detects the working signal of the earphone to be tested in real time, and feeds back the working signal to the background terminal or the cloud for storage, so that the staff can view it, wherein the working signal may refer to whether the earphone to be tested plays audio normally, etc. In addition, the earphone function test device can also control the first drive component 30 and the second drive component 40 to stop rotating, so that the earphone to be tested is determined to be in the unworn state, and then the signal detection module is used to detect in real time whether the earphone to be tested still has a working signal. When the signal detection module detects that the earphone to be tested has a working signal when it is in the wearing state, that is, the earphone to be tested works normally, and when the earphone to be tested does not have a working signal when it is in the unworn state, that is, when the earphone to be tested is suspended, it indicates that the earphone to be tested is a qualified product, thereby improving the automation degree of testing the normal function of the earphone to be tested and improving the test efficiency. It should be noted that since the signal detection module detects the earphone to be tested by wireless means such as Bluetooth or WIFI, the signal detection module can be set on the earphone function test device, or can also be set on other devices such as mobile terminals or background terminals.

[0033] The technical solution of the present invention places the earphone to be tested on the workbench 10, and the first driving component 30 drives the workbench 10 to rotate on the rotating table 20, thereby driving the earphone to be tested to rotate in the first direction; when the second driving component 40 drives the rotating table 20 to rotate, it indirectly drives the workbench 10 set on the rotating table 20 to rotate, thereby driving the earphone to be tested to rotate in the second direction; the earphone to be tested rotates in the first direction and the second direction to simulate the movement trajectory of the user wearing the earphone to be tested, and the signal detection module detects the working signal when the simulated user wears the earphone to be tested to determine whether the earphone to be tested is normal, thereby improving the automation level of testing the normal function of the earphone to be tested and improving the test efficiency.

[0034] For details, please refer to Figure 1-Figure 4The first driving assembly 30 includes a first motor 31 and a support frame 32 and a support plate 33 which are arranged opposite to each other. A driving shaft 34 is provided on the support frame 32, and the driving shaft 34 is rotatably connected to the support frame 32. A driven shaft 35 corresponding to the driving shaft 34 is provided on the support plate 33, and the driven shaft 35 is rotatably connected to the support plate 33. One end of the rotating table 20 is connected to the driving shaft 34, and the other end is connected to the driven shaft 35. The first motor 31 is arranged on the support frame 32, and the output shaft of the first motor 31 is connected to the driving shaft 34 through a coupling to drive the rotating table 20 to rotate around the first direction between the support frame 32 and the support plate 33.

[0035] In this embodiment, in order to ensure the stability of the rotating table 20, the rotating table 20 is suspended between the support frame 32 and the support plate 33, and is connected to the driving shaft 34 and the driven shaft 35 respectively, so that when the output shaft of the first motor 31 drives the driving shaft 34 to rotate, the driving shaft 34 drives the rotating table 20 and the driven shaft 35 to rotate, thereby realizing the rotation of the rotating table 20 around the first direction between the support frame 32 and the support plate 33, wherein the rotation around the first direction refers to the axial rotation of the rotating table 20 around the output shaft of the first motor 31. In order to further improve the stability of the rotating table 20, a rib plate 38 is provided on the side of the support plate 33 away from the support frame 32, so as to improve the stability of the support plate 33.

[0036] In addition, the headphone function test device includes but is not limited to the above-mentioned scheme. The rotating table 20 can be set on the support frame 32 only through the driving shaft 34, thereby reducing the size of the headphone function test device to adapt to different application scenarios, thereby improving the compatibility of the headphone function test device described in the present invention.

[0037] Furthermore, the first driving component 30 also includes a first angle sensor 36, which is arranged on the driving shaft 34 or the driven shaft 35 and is electrically connected to the signal detection module. When the first motor 31 drives the rotating table 20 to rotate, the first angle sensor 36 detects the rotation angle of the driving shaft 34 or the driven shaft 35 in real time, and feeds it back to the signal detection module, and the signal detection module feeds it back to the background terminal so that the staff can record the angle range that the first motor 31 needs to rotate when the earphone to be tested is in the wearing state, so as to further determine the quality of the earphone to be tested. In order to further optimize the structure of the earphone function testing equipment, the first angle sensor 36 can be installed on the driven shaft 35, so as to save the installation space on the support frame 32.

[0038] Further, a first limiting plate 37 is provided at the top edge of the support plate 33 and / or at both side edges of the support plate 33, and the first limiting plate 37 is detachably connected to the support plate 33. The first limiting plate 37 and the support plate 33 can be connected by screws, and screw holes are provided at the edge of the support plate 33, so that the first limiting plate 37 is fixed to the support plate 33 by the cooperation between the screws and the screw holes. The first limiting plate 37 is provided at the top edge and at least one of the two side edges of the support plate 33, so that the rotating table 20 abuts against the first limiting plate 37 during the rotation process, thereby preventing the rotating table 20 from continuing to rotate, so as to avoid the rotating table 20 rotating too much and causing the test result of the headphone function test device to be affected. In this embodiment, the first limiting plate 37 and the support plate 33 are detachably connected, so as to facilitate the replacement of the first limiting plates of different sizes and shapes to adapt to different working scenes, thereby improving the compatibility of the headphone function test device.

[0039] It should be noted that a plurality of threaded holes may be evenly opened on the edge of the support plate 33 , so that the rotatable angle range of the rotating table 20 can be adjusted by replacing the first limiting plate 37 to different positions to meet the requirements of different tests.

[0040] For details, please refer to Figure 1 and Figure 5 , the second driving assembly 40 includes a second motor 41, the second motor 41 is arranged on the rotating table 20, and the output shaft of the second motor 41 is connected to the workbench 10 through a coupling to drive the workbench 10 to rotate around the second direction relative to the rotating table 20. In this embodiment, in order to further optimize the structure of the headphone function test device and reduce the size, the second motor 41 is arranged on the side of the rotating table 20 away from the workbench 10, and a hollow structure is arranged on the rotating table 20, the output shaft of the second motor 41 passes through the hollow structure and is connected to the workbench 10 through a coupling to drive the workbench 10 to rotate around the second direction on the rotating table 20. Among them, the rotation around the second direction refers to the axial rotation of the workbench 10 around the output shaft of the second motor 41.

[0041] Furthermore, the second driving component 40 also includes a second angle sensor 42, which is arranged on the second motor 41 and is electrically connected to the signal detection module. When the second motor 41 drives the workbench 10 to rotate, the second angle sensor 42 detects the angle rotated by the output shaft of the second motor 41 in real time, and feeds it back to the signal detection module, which then feeds it back to the back-end terminal, so that the staff can record the angle range that the second motor 41 needs to rotate when the headset to be tested is in the wearing state, so as to further determine the quality of the headset to be tested.

[0042] Furthermore, a second limit plate 43 is provided on the rotating table 20, and the second limit plate 43 is located on one side of the workbench 10, and the second limit plate 43 is detachably connected to the rotating table 20. The second limit plate 43 and the rotating table 20 can be connected by screws, and the second limit plate 43 is set on one side of the workbench 10 so that the workbench 10 abuts against the second limit plate 43 during the rotation process, thereby preventing the workbench 10 from continuing to rotate, so as to avoid the workbench 10 rotating too much and causing the test results of the headphone function test equipment to be affected. In this embodiment, the second limit plate 43 is similar to the first limit plate 37, and the position of the second limit plate 43 can be adjusted by opening a plurality of screw holes on the rotating table 20, thereby adjusting the rotatable angle range of the workbench 10 to meet the needs of different tests.

[0043] This embodiment includes but is not limited to the above-mentioned solution. The second limit plate 43 can also be fixed on the workbench 10, so that when the workbench 10 rotates, the second limit plate 43 abuts against the edge of the rotating table 20, thereby also preventing the workbench 10 from continuing to rotate.

[0044] For details, please refer to Figure 5 , the headphone function test equipment also includes a gray card (not marked in the figure), the workbench 10 is provided with a guide pin 11 and a gray card receiving slot 12, the gray card is detachably arranged in the gray card receiving slot 12, and each of the two sides of the gray card receiving slot 12 is provided with a guide pin 11. Among them, the two guide pins 11 can be staggered, that is, arranged on the diagonal line of the gray card receiving slot 12, so that the headphone to be tested is placed along the diagonal line of the gray card to reduce the size of the gray card. The gray card is used to simulate human skin, and the headphone to be tested is placed on the gray card, and the two ends of the headphone to be tested are clamped on the two guide pins 11 for fixation. When the sensor on the headphone to be tested detects the gray card, it is determined that it is in the wearing state.

[0045] In this embodiment, in order to improve the detection accuracy of the headphone function test device, the gray card, the first drive component 30 and the second drive component 40 are used to simulate the process of a user wearing headphones. That is, the headphones to be tested must simultaneously meet the conditions of being placed on the gray card, rotating in the first direction and rotating in the second direction to be determined as being in a wearing state, thereby avoiding misjudgment of the headphones to be tested and improving the accuracy of the test.

[0046] Furthermore, the headphone function testing equipment also includes an headphone clip assembly 50, which includes a clamp 51, a torsion spring frame 53 and a torsion spring 52 arranged on the torsion spring frame 53, the torsion spring frame 53 is arranged on one side of the gray card accommodating slot 12, the clamp 51 is located above the gray card accommodating slot 12, and the clamp 51 is connected to one torsion arm of the torsion spring 52, and the other torsion arm of the torsion spring 52 is connected to the torsion spring frame 53, and the clamp 51 is rotated through the torsion spring 52 to cooperate with the guide pin 11 to clamp the earplug part of the headphone to be tested.

[0047] In this embodiment, the clamping plate 51 is pressed against the gray card accommodating groove 12 and the guide pin 11 by the force of the torsion spring 52, so that the earphone to be tested is pressed between the two guide pins 11, and the earphone to be tested is fixed at this position to prevent the workbench 10 from being thrown out of the workbench when the workbench 10 rotates under the action of the first driving member 30 and the second driving member 40. After the test is completed, the staff presses the end of the clamping plate 51 connected to the torsion spring 52 to open the clamping plate 51 to take out the earphone to be tested.

[0048] In order to further improve the stability of the earphone clip assembly 50, a locking member 54 can also be set at the edge of the clamping plate 51, and the clamping plate 51 can be fixed to the workbench by the locking member 54, so as to prevent the clamping plate 51 from opening when the workbench 10 rotates under the action of the first driving member 30 and the second driving member 40.

[0049] Furthermore, the clamping plate 51 is provided with an avoidance groove 511, which is used to avoid the touch rod of the headset to be tested, and the avoidance groove 511 is arranged corresponding to the position of the gray card accommodating groove 12. In this embodiment, since the touch rod of the headset to be tested is relatively fragile, the avoidance groove 511 is arranged to prevent the clamping plate 51 from pressing on the touch rod of the headset to be tested and causing damage to the headset to be tested. At the same time, by providing the avoidance groove 511, it is also convenient for the staff to operate the touch rod of the headset to be tested during the test.
