Description

Technical Field

[0001] The utility model relates to the technical field of earphone testing, in particular to a rotating and fixing testing fixture for headphones. Background Art

[0002] Headphones usually consist of two main parts: the headphone unit and the head-mounted device. The head-mounted device refers to the device that fixes the headphone unit to the head, usually including a headband and one or two earmuffs or ear hooks. The headband is usually made of adjustable material and can be adjusted according to the size of the head. The earmuffs or ear hooks are responsible for placing the headphone unit on the ear. They can be rotatable or adjustable to adapt to different ear sizes and shapes. The microphone rod of the headset is the part that connects the microphone head and the headphone shell. Its main function is to fix the external microphone. Without the microphone rod, the external microphone cannot be fixed on the headset, so a microphone rod is needed to connect and fix it. Conventional headphone microphone rods need to undergo rotational aging life tests during the development and production process to ensure the effectiveness of sliding damping.

[0003] In the patent with the authorized patent name of "Universal Headphone Microphone Arm Rotation Life Test Fixture" and the patent number of CN217116405U, it is proposed that the fixture is generally only applicable to one or a few types of headphones. With the update of the project, the corresponding fixture will also be eliminated, which causes a waste of equipment resources and increases costs. By designing the clamping mechanism and support mechanism of the headphone shell and the headband into an adjustable structure, it can be adjusted larger for larger headphones and smaller for smaller headphones. In this way, it can adapt to headphones of different sizes and types, and the replacement operation is convenient, which can achieve a universal effect. However, during the test, the direction of rotation of the microphone rod is fixed, and it can only be cyclically rotated according to the specified angle and direction, and cannot be continuously tested at the specified angle. Under the design of some commonly used headphones, the headphones cannot rotate in the full range, but can only rotate to the specified angle. The above technical content has certain limitations in the test process of such headphones and microphone rods. Utility Model Content

DETAILED DESCRIPTION

[0025] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0026] See also Figure 1-Figure 6 , the utility model provides a technical solution:

[0027] A headphone rotation and fixing test fixture comprises: a carrying box 10, a driving rotation structure 12 is fixedly connected to the carrying box 10, a rotating end of the driving rotation structure 12 is fixedly connected to a rotating support seat 13, a clamping structure 14 is fixedly connected to the outside of the rotating support seat 13, an earmuff is clamped on the rotating support seat 13, the clamping structure 14 is used to position the earmuff on the rotating support seat 13, and a single-side support seat 11 is fixedly connected to the carrying box 10;

[0028] Among them, the driving rotation structure includes a driving motor 20 and a fixed seat 21, both of which are fixedly connected to the carrier box 10, and the internal rotation of the fixed seat 21 is connected to a connecting rod 24, and the outside of the connecting rod 24 and the output shaft of the driving motor 20 are fixedly connected to synchronous wheels, and the two synchronous wheels are connected through a synchronous belt transmission, and the outside of the fixed seat 21 is fixedly connected to an angle display panel 22, and one end of the connecting rod 24 away from the fixed seat 21 passes through the outside of the angle display panel 22 and is fixedly connected to a rotating pointer 23, and the outside of the connecting rod 24 is fixedly connected to the rotating support seat 13, and the rotating pointer 23 is located on the rotating support seat 13.

[0029] Specifically, during use, the staff places the earmuff on one side of the headset that needs to be tested on the rotating support seat 13, and limits and fixes the earmuff placed on the rotating support seat 13 through the clamping structure 14. After the limiting and fixing are completed, the driving rotating structure 12 is started to drive the rotating support seat 13 to perform a flip test. In the process of driving the rotating structure 12 to drive the rotating support seat 13 to flip, the rotation of the rotating support seat 13 will drive the rotating pointer 23 to rotate. The rotation of the rotating pointer 23 will point to an angle on the angle display panel 22, so that the user can directly observe the angle of the headset currently undergoing the rotation test, thereby avoiding damage to the headset due to excessive rotation test.

[0030] like Figure 6As shown, the clamping structure 14 includes a support rod 40, which is connected to the rotating support seat 13 through a positioning bolt 50. The outside of the support rod 40 is movably connected to a first positioning plate 41, and the outside of the first positioning plate 41 is hinged to a second positioning plate 42. The end of the second positioning plate 42 away from the support rod 40 is clamped to the inside of the earmuff. The outside of the second positioning plate 42 and the first positioning plate 41 are provided with threaded holes matching the positioning bolts 50, and positioning tension springs 51 are sleeved between the multiple positioning bolts 50.

[0031] Specifically, when using the snap-fit ​​structure 14 to position the earmuffs on the rotating support seat 13, the user rotates the first positioning plate 41 and the second positioning plate 42 through the support rod 40 and snaps the second positioning plate 42 into the earmuff. When the second positioning plate 42 is snapped into the earmuff, the positioning springs 51 outside the plurality of positioning bolts 50 will tension the first positioning plate 41 and the second positioning plate 42. By adjusting the tension between the first positioning plate 41 and the second positioning plate 42 to a suitable degree, the positioning of the earmuffs on the rotating support seat 13 through the second positioning plate 42 can be achieved. A snap-fit ​​groove matching the earmuffs is provided on the rotating support seat 13. The earmuffs to be tested can be further positioned by setting the snap-fit ​​groove.

[0032] Furthermore, considering that headphones of different sizes may appear during the test, in order to ensure that earmuffs of different sizes can be limited, the user can install the support rod 40 to different positions of the rotating support base 13 through different threaded holes, and threadably connect the positioning bolt 50 to different positions of the support rod 40, and connect the positioning spring 51 with different tensions to realize that the first positioning plate 41 and the second positioning plate 42 can press and limit the earmuffs in real time. When the earmuffs need to be removed, only the second positioning plate 42 needs to be pushed outward to separate the second positioning plate 42 from the earmuffs, thereby canceling the positioning effect of the second positioning plate 42 on the earmuffs.

[0033] like Figure 5 As shown, a positioning seat 30 is fixedly connected to the carrier box 10, and a top-pressure positioning rod 31 is movably connected inside the positioning seat 30. A supporting seat 32 is fixedly connected outside the positioning seat 30. A receiving groove matching the ear strap is opened on the supporting seat 32, and the ear strap is connected to the inside of the receiving groove.

[0034] Specifically, during the earmuff test, the overall stability of the headset needs to be ensured. When one earmuff is rotating, the ear strap may shake. At this time, the ear strap close to the earmuff can be placed inside the top-pressing positioning rod 31, and the pressing switch of the top-pressing positioning rod 31 can be toggled to push the top-pressing positioning rod 31 out, thereby limiting and fixing the ear strap inside the receiving groove of the top-pressing positioning rod 31.

[0035] Specifically, a carrying block 70 is fixedly connected to the carrying box 10, and the outer part of the ear band is connected to the carrying block 70. The carrying block 70 is provided to further support the ear band to ensure the stability of the headphone during the test.

[0036] like Figure 3-Figure 4 As shown, a main controller 60 is installed inside the carrier box 10, and a touch display screen 61 is installed on the outer wall of the carrier box 10. The main controller 60 is electrically connected to the drive motor 20 and the touch display screen 61 respectively. A control switch is installed outside the carrier box 10, and the control switch is electrically connected to the main controller 60. After the staff presses the control switch, the main controller 60 will issue a power-on command to the drive motor 20, so that the drive motor 20 rotates. At the same time, the working process and working status are displayed through the touch display screen 61, and the user can also feedback the angle adjustment instruction to the main controller 60 through the touch display screen 61, and the main controller 60 controls the drive motor 20 to drive the rotating support seat 13 to rotate at a specified angle.

[0037] Specifically, the single-sided support seat 11 includes a supporting plate 80 and a supporting plate 81. The supporting plate 81 is fixedly connected to the supporting box 10, and the supporting plate 80 is rotatably connected to the outside of the supporting plate 81. The earmuffs that are not tested can be supported by the arrangement of the supporting plate 80 and the supporting plate 81, and the supporting plate 80 is hinged on the supporting plate 81, which is convenient for adjusting the earmuffs on one side to a specified angle during the test of the earmuffs on one side, so as to facilitate the detection.

[0038] Specifically, the outside of the carrier box 10 is hinged with multiple side cover plates 91, and buckles 92 are installed on the carrier box 10 and the side cover plates 91. The carrier box 10 as a whole is composed of an upper plate body, surrounding side plates and a bottom plate body. The testing process is completed on the upper plate body. The surrounding side plates and the bottom plate body carry the main controller 60 and the internal power supply to protect the main controller 60 and the internal power supply. When the interior needs to be inspected, the buckles 92 can be opened, so that the two buckles 92 can be flipped outward and the carrier box 10 can be flipped upward, so that the interior of the carrier box 10 can be inspected.

[0039] Specifically, a plurality of rubber support feet 90 are installed at the bottom of the carrier box 10. The arrangement of the plurality of rubber support feet 90 ensures the stability of the carrier box 10 during operation, increases the friction between the carrier box 10 and the supporting table, and supports the carrier box 10 as a whole.

[0040] The working steps of this scheme are summarized and sorted out according to the above technical scheme: during use, the staff places the earmuff on the side that needs to be tested on the rotating support seat 13, and positions the earmuff on the rotating support seat 13 through the first positioning plate 41 and the second positioning plate 42 to prevent the earmuff from falling during the rotation test. After the fixation is completed, the staff sends information to the main controller 60 through the switch, and controls the drive motor 20 to rotate through the main controller 60, thereby driving the connecting rod 24 to rotate through the synchronous belt and the synchronous wheel. The rotation of the connecting rod 24 will drive the rotating support seat 13 and the rotating pointer 23 to rotate. The rotation of the rotating support seat 13 will drive the earmuff to perform a rotation test, and the rotating pointer 23 will rotate with the earmuff. During the rotation process, the rotating pointer 23 will point to different angles on the angle display panel 22, so that the staff can observe the test angle of the headset and test the specified angle of the headset.

[0041] Parts not involved in the present invention are the same as the prior art or can be implemented by the prior art. Although the embodiments of the present invention have been shown and described, it is understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the attached claims and their equivalents.
