[0018] To explain in detail the technical content, objectives, and effects of this utility model, the following description is provided in conjunction with the embodiments and accompanying drawings.

[0019] Please refer to Figures 1 to 5 A speaker module testing fixture includes a base 1, a cover plate 2, and a pressing member 3. The base 1 has a placement groove 11 for placing a speaker module 7 to be tested. One end of the cover plate 2 is rotatably connected to the base 1, and the cover plate 2 has several sliding grooves 21. The pressing member 3 includes a screw part 31 and an upper nut 32 and a lower nut 33 respectively threaded onto the screw part 31. The bottom of the screw part 31 is eccentrically provided with a pressing part 34, which is used to press the screw mounting hole 71 area of ​​the speaker module 7 to be tested. The screw part 31 passes through the sliding grooves 21. The upper nut 32 abuts against the top surface of the cover plate 2, and the lower nut 33 abuts against the bottom surface of the cover plate 2.

[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: This speaker module testing fixture achieves compatibility of a single set of testing fixtures with speaker modules at different screw mounting hole 71 positions through the sliding cooperation between the sliding groove 21 on the cover plate 2 and the pressing part 3, combined with the eccentric pressing part 34. This significantly improves the versatility of the testing fixture, eliminating the need to manufacture matching fixtures for each speaker module separately, thereby greatly reducing the manufacturing and management costs of the fixture. The pressing part 3 can be flexibly adjusted along the sliding groove 21 and quickly locked by double nuts, making the changeover operation simple and quick, effectively shortening the test preparation time and improving the test efficiency. At the same time, the eccentrically set pressing part 34 can accurately apply clamping force to the screw mounting hole 71 area. Combined with the rotating connection structure between the cover plate 2 and the base 1, it ensures that the clamping is stable and reliable, guaranteeing the consistency and accuracy of the test process.

[0021] Furthermore, the screw portion 31 is welded and fixed to the pressing portion 34; or, the screw portion 31 and the pressing portion 34 are integrally formed into a single structure.

[0022] As described above, by welding or integrally forming the screw part 31 and the pressing part 34, the overall structural strength and rigidity of the pressing part 3 are significantly enhanced. This effectively avoids the loosening, deflection or displacement problems that may occur during repeated clamping of the split structure, and ensures the long-term stability of the relative position accuracy between the pressing part 34 and the screw part 31. This ensures the reliable transmission of clamping force and the repeatability of the testing process, and extends the service life of the tooling.

[0023] Furthermore, a buffer pad 35 is provided at the bottom end of the pressing part 34.

[0024] As described above, the buffer pad 35 at the bottom of the pressing part 34 can effectively prevent the rigid pressing part 34 from directly contacting the surface of the speaker module 7 under test, thus preventing damage such as pressure marks and scratches. At the same time, the buffer pad 35 increases the friction coefficient of the contact surface, improves the clamping stability, and can also absorb the small impact vibrations during the clamping process, further improving the consistency and safety of the test.

[0025] Furthermore, the cover plate 2 is provided with multiple sliding grooves 21, and any two sliding grooves 21 are arranged in parallel.

[0026] As described above, the cover plate 2 is provided with multiple parallel sliding grooves 21, which greatly expands the adjustment range and layout flexibility of the pressing part 3, so that a single set of speaker module testing fixtures can be compatible with more speaker modules of different sizes and different screw hole arrangements. Quick changeover can be achieved without replacing the cover plate 2, further improving the versatility and adaptability of the speaker module testing fixture.

[0027] Furthermore, the cover plate 2 is also provided with test probes 22 for supplying power to the speaker module 7 under test.

[0028] As described above, integrating test probes 22 on the cover plate 2 enables the simultaneous completion of mechanical clamping of the speaker module and power supply for electrical performance testing. This eliminates the cumbersome operation of additional wiring, simplifies the testing process, significantly shortens the preparation time for a single test, improves overall testing efficiency, and avoids potential contact problems or interference issues caused by external wires.

[0029] Furthermore, the other end of the cover plate 2 is provided with a first magnetic attractor, and the base 1 is provided with a second magnetic attractor that magnetically engages with the first magnetic attractor.

[0030] As described above, the cover plate 2 and the base 1 are magnetically attracted by the first magnetic attraction component and the second magnetic attraction component, which enables the cover plate 2 to close quickly and be initially positioned. The operation is simple and quick, and the magnetic attraction force can effectively prevent the cover plate 2 from opening accidentally during the test, ensuring the continuity and stability of the test and improving the ease of use and safety of the tooling.

[0031] Furthermore, the other end of the cover plate 2 is an operating part 23.

[0032] As described above, the other end of the cover plate 2 is configured as the operating part 23, which provides the operator with an ergonomic grip or force application position, making it easy to quickly open and close the cover plate 2, reducing operator fatigue, improving clamping efficiency, and avoiding possible misoperation or contamination caused by direct contact with other functional areas of the cover plate 2.

[0033] Furthermore, the base 1 is also provided with a first elbow clamp 4, which is used to press the cover plate 2.

[0034] As described above, the base 1 is provided with a first elbow clamp 4 for pressing the cover plate 2, which can provide additional and reliable clamping force to the cover plate 2, ensuring the tightness of the closure between the cover plate 2 and the base 1, effectively preventing problems such as air leakage and loosening caused by air pressure changes or mechanical vibration during testing, and ensuring the sealing of the test environment and the accuracy of acoustic test data.

[0035] Furthermore, it also includes a front cavity pipe 6, a fixing plate 51, and a fixing block 52 disposed on the fixing plate 51. The fixing plate 51 is provided with a test port 511, and the fixing block 52 is provided with a second elbow clamp 53. The second elbow clamp 53 presses against the base 1 so that the base 1 abuts against the fixing plate 51. The front cavity pipe 6 connects to the fixing plate 51 and communicates with the test port 511. The front cavity pipe 6 is used to connect to the sound outlet of the speaker module 7 to be tested.

[0036] As described above, by adding the front cavity pipe 6, the fixing plate 51, the fixing block 52, and the second elbow clamp 53, a complete acoustic testing environment is constructed. The front cavity pipe 6 can simulate the sound output channel of the speaker module in the real whole machine. The second elbow clamp 53 ensures the tight fit and sealing between the base 1 and the front cavity pipe 6, making the test closer to the actual working conditions, thereby greatly improving the authenticity and predictive value of the test data.

[0037] Furthermore, the front cavity pipe 6 is detachably connected to the fixing plate 51.

[0038] As described above, the front cavity pipe 6 and the fixing plate 51 are detachably connected, which makes it easy to quickly replace the matching front cavity pipe 6 according to the sound outlet specifications of different speaker modules. This avoids the cost increase caused by replacing the entire set of test fixtures, further enhances the versatility and scalability of the test fixtures, and reduces the investment in test equipment for multiple product models.
