[0006] Preferably, headphones are clamped on the headphone fixed base and the headphone movable base.

[0007] Beneficial effects of the utility model:

[0008] The utility model clamps the headset on the headset base, and then the headset movable base repeatedly moves back and forth in a linear manner within a set data range to achieve a back and forth cyclic pulling of the headband to obtain fatigue test data. The operation is simple and easy to maintain, and it is suitable for general headset test sites. BRIEF DESCRIPTION OF THE DRAWINGS

[0009] The utility model is described in detail below with reference to the accompanying drawings and specific implementation methods;

[0010] Figure 1 It is a structural schematic diagram of the utility model. DETAILED DESCRIPTION

[0011] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific implementation methods.

[0012] Reference Figure 1 , this specific implementation adopts the following technical scheme: a fatigue test tooling for a universal headphone headband, including a box body 1, a touch display screen 2, a PLC3, a screw 4, a movable screw support 5, a screw fixing seat 6, a coupling 7, a servo motor 8, a headphone fixed base 9, a headphone movable base 10, a headphone movable base support plate 11 and a linear slide rail 12. A touch display screen 2 is arranged on the front of the box body 1, a PLC3 is arranged in the box body 1, the PLC3 is connected to the servo motor 8 and the touch display screen 2, the servo motor 8 is connected to the screw 4 through the coupling 7, a linear slide rail 12 and a headphone fixed base 9 are arranged on the substrate at the top of the box body 1, a headphone movable base 10 is arranged on one side of the headphone fixed base 9, the headphone movable base 10 is fixed to the headphone movable base support plate 11 by screws, the linear slide rail 12 is slidably matched with the headphone movable base support plate 11, a movable screw support 5 is fixed to the headphone movable base support plate 11 by screws, the movable screw support 5 is also connected to the screw 4, and the screw 4 is supported on the screw fixing seat 6.

[0013] It is worth noting that headphones are clamped on the headphone fixed base 9 and the headphone movable base 10.

[0014] The working principle of this specific implementation method is: clamp the headphones on the headphone base, set the required time, speed, number of times, stroke, etc. on the touch screen, click start, the PLC transmits the signal to the servo motor, the servo motor drives the coupling, the coupling drives the lead screw, the lead screw 4 drives the movable lead screw support 5 to move, the movable lead screw support 5 drives the headphone movable base 10 to move linearly on the linear slide rail 12, when the set stroke is reached, the servo motor reverses, and the headphone movable base 10 will return, thereby repeating the movement to achieve a back-and-forth cycle of pulling the headband to obtain fatigue test data.

[0015] This specific implementation is suitable for fatigue testing of universal headbands and earphone headbands. The touch screen is easy to operate, displays clear data, and can arbitrarily adjust the speed, number of times, time, stroke, etc.
