DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-4 A headphone testing device comprises a bottom plate 1, an arc bracket 2 and a headphone to be tested 3, wherein the arc bracket 2 is fixed to the top of the bottom plate 1, a clamping mechanism 4 is provided on the top of the arc bracket 2, a T-shaped rod 5 is movably connected to the front of the arc bracket 2, an adjustment mechanism 6 is provided between the T-shaped rod 5 and the arc bracket 2, telescopic rods 7 are movably connected to both ends of the T-shaped rod 5, a support plate 8 is fixed to the outside of the telescopic rod 7, a clamping mechanism 9 is provided between the telescopic rod 7 and the T-shaped rod 5, and a test decibel meter 1 is fixed to the top of the bottom plate 1 1. The test decibel meter 11 can display the volume of the headset at different distances, and can test the volume of the headset; the test device can clamp the top of the headset of different sizes through the sliding rod 41 at the top, the clamping block 43 and the first spring 44, and the headset part can be stretched and fixed through the telescopic rods 7 on both sides. At the same time, the distance between the headset and the test decibel meter can be adjusted, and the headset part can be made parallel to facilitate the test work. The support position on both sides can be adjusted through the threaded rod 62 and the T-bar 5, which is convenient for testing headsets of different sizes.

[0021] In this embodiment, the clamping mechanism 4 includes a sliding rod 41, which is slidably connected to the top of the arc-shaped bracket 2. A limiting plate 42 is fixed to one end of the sliding rod 41, and a clamping block 43 is fixed to the other end of the sliding rod 41. A first spring 44 is sleeved on the surface of the sliding rod 41. The sliding rod 41 cooperates with the clamping block 43 and the first spring 44 to clamp the tops of headphones of different sizes.

[0022] Furthermore, a vertical plate 10 is fixed on the top of the clamping block 43, and the cross-section of the sliding rod 41 is square. The vertical plate can limit the earphone, and the square shape can prevent the sliding rod 41 from passively rotating.

[0023] Furthermore, the adjustment mechanism 6 includes a protrusion 61, and the protrusion 61 is fixed to the front side of the arc-shaped bracket 2. The bottom of the protrusion 61 is rotatably connected to a threaded rod 62, and the threaded rod 62 is threadedly connected to the T-bar 5. A fixed block 63 is fixed to the front side of the arc-shaped bracket 2, and the fixed block 63 is rotatably connected to the threaded rod 62. The support position on both sides can be adjusted by cooperating with the T-bar 5 through the threaded rod 62, and the distance between the earphones on both sides and the test decibel meter 11 can be controlled.

[0024] In addition, the clamping mechanism 9 includes a groove 91, which is opened on the surface of the telescopic rod 7. A latch tooth 92 is fixed on the inner side of the groove 91. Two fixed frames 93 are fixed on the front side of the T-shaped rod 5. A positioning block 94 is slidably connected between the fixed frames 93. A second spring 95 is provided on the inner side of the fixed frame 93. The two sides of the second spring 95 respectively contact the fixed frame 93 and the positioning block 94. The positioning block 94 is movably connected to the latch tooth 92. The positioning block 94 can clamp the telescopic rod 7 to facilitate length adjustment.

[0025] It should be noted that one end of the positioning block 94 is provided with a chamfered structure, and the side of the latching tooth 92 that contacts the chamfered structure is provided with an arc structure. The chamfered structure can facilitate unidirectional stretching and can be quickly adjusted.

[0026] Working method: When conducting an earphone test, the staff can pull the clamping block 43 outward, and the clamping block 43 can drive the sliding rod 41 and the limit plate 42 to squeeze the first spring 44. Then, the connecting part of the earphone 3 to be tested is placed on the inner side of the vertical plate 10 and the clamping block 43 is released. Under the action of the first spring 44, the connecting part of the earphone 3 to be tested is clamped. At this time, the two sides of the earphone 3 to be tested will be clamped in the position of the support plates 8 on both sides. Then, rotating the threaded rod 62 can drive the T-bar 5 to move up and down to adjust the supporting position. Finally, pull out the positioning block 94 and squeeze the second spring 95. Then, pull out the telescopic rod 7 to prop up the two ends of the earphone 3 to make the earphone parts parallel for testing. During the test, the position of the earphones on both sides can be adjusted to test the volume.
