[0027] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] In the description of this utility model, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", etc., indicating the orientation or positional relationship are based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this utility model and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model.

[0029] In this utility model, unless otherwise explicitly specified and limited, the terms "installation", "setting", "connection", "fixing", "screw connection", etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal connection of two components or the interaction between two components. Unless otherwise explicitly limited, those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this utility model, "a plurality of" means two or more, unless otherwise explicitly specified.

[0031] Example: As attached Figure 1 - Appendix Figure 6 As shown, a testing device for a vehicle-mounted microphone includes a turntable body 1, a turntable motor 2 that controls the rotation of the turntable body 1, the turntable motor 2 and the turntable body 1 being on the same axis, four microphone positioning fixtures 3 on the turntable body 1, the microphone positioning fixtures 3 being evenly distributed on the turntable body 1, an audio socket testing component 4 being provided on one side of each microphone positioning fixture 3, and an origin detection fixing bracket 5 being provided on one side of the turntable motor 2, with an origin detection sensor 6 provided on the origin detection fixing bracket 5.

[0032] The audio jack testing assembly 4 includes a test base 41, with a headphone audio jack 42 provided on one side of the test base 41. The test base 41 is a polyetheretherketone (PEEK) test base, and the headphone audio jack 42 is a polyoxymethylene (POM) headphone audio jack.

[0033] The test base 41 is provided with two copper pillar mounting holes 411 and a test hole 412. Each copper pillar mounting hole 411 is provided with a copper pillar 43. The end of the copper pillar 43 near the headphone audio jack 42 extends and connects to the headphone audio jack 42. The end of the copper pillar mounting hole 411 away from the headphone audio jack 42 is provided with a copper pillar set screw 44. A compression spring 45 is provided between the copper pillar set screw 44 and the copper pillar 43. The copper pillar set screw 44 and the compression spring 45 allow the copper pillar 43 to make better contact with the headphone audio jack 42.

[0034] The copper pillar 43 includes a cylindrical first copper pillar body 431, and a cylindrical second copper pillar body 432 extending from one end of the first copper pillar body 431 near the headphone audio jack 42. The axis of the second copper pillar body 432 does not coincide with the axis of the first copper pillar body 431, and the diameter of the second copper pillar body 432 is smaller than the diameter of the first copper pillar body 431. This biased structure design can prevent the copper pillar 43 from rotating in the test base 41. The first copper pillar body 431 is provided with a planar groove 433, which corresponds to the position of the test hole 412. The design of the planar groove 433 allows the test probe to better contact the copper pillar 43.

[0036] The microphone positioning fixture 3 includes a fixture body 31 fixed on the turntable body 1, and the fixture body 31 is provided with a microphone placement groove 32 that matches the shape of the microphone.

[0037] This utility model has four working positions: loading position, assembly position, testing position, and unloading position. Each working position consists of the microphone positioning fixture 3 and the audio socket testing assembly 4.

[0038] The loading position is when the turntable body 1 is moved to this position, and the microphone 7 is manually inserted into the microphone placement groove 32 on the microphone positioning fixture 3, and the microphone audio plug 8 is inserted into the headphone audio socket 42.

[0039] The test position is reached when the turntable body 1 moves to this position, and the test probe (not shown in the figure) is driven by the cylinder to press down onto the flat groove 433 on the copper pillar 43 to complete the automatic test.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
