[0042] See also Figure 1 and Figure 2 The utility model provides an artificial ear connection fixture, including a fixture base 1 and a buckle assembly 2.

[0043] The jig base 1 is provided with a slot 1011 for receiving the earphone under test. A through-hole 103 extending through the jig base 1 is provided in the slot 1011, corresponding to the sound outlet of the earphone under test. The through-hole 103 connects the sound outlet to the artificial ear. One end of the clip assembly 2 is hinged to the jig base 1, and the other end is clipped to the jig base 1, cooperating with the jig base 1 to press the earphone under test.

[0044] When performing an acoustic test on the earphone under test, the artificial ear connection jig provided in this embodiment first opens the buckle assembly 2, then places the earphone under test into the component placement slot 1011, and then closes the buckle assembly 2. At this point, the sound outlet of the earphone under test is aligned with the through hole 103.

[0045] Next, the artificial ear connection fixture is placed on the artificial ear, and the through hole 103 is aligned with the artificial ear. During the subsequent acoustic test, the sound emitted by the earphone under test through the sound outlet can directly enter the artificial ear through the through hole 103, and then the various sensors inside the artificial ear collect and analyze the sound.

[0046] When testing a different headphone, simply replace the artificial ear connection jig. The artificial ear containing the jig can be reused. The jig is a purely machined component, offering low cost and a simple manufacturing process. This reduces material costs and shortens the production cycle.

[0047] Therefore, the artificial ear connection fixture provided in this embodiment can effectively reduce the difficulty of adapting the headphone to be tested and the artificial ear, thereby reducing the testing cost and shortening the testing cycle.

[0048] In the embodiment, the jig base 1 comprises a metal piece 101 provided with the placing groove 1011, and the metal piece 101 is provided with an inlay groove corresponding to the position of the sound hole of the earphone to be tested; and the inlay groove is provided with a flexible profile inlay 102.

[0049] On the one hand, the flexible profile inlay 102 can improve the fit between the artificial ear connecting jig and the earphone to be tested, thereby avoiding the "leakage" problem caused by the poor sealing between the earphone to be tested and the artificial ear connecting jig; on the other hand, in order to obtain a more comfortable wearing experience, different manufacturers will design earphone heads of different shapes according to their own research results, and further, the sound hole is usually located at the head of the earphone, so the structure of the earphone to be tested at the position of the sound hole is usually complex, and the metal piece 101 is difficult to meet the complex modeling requirements, and the use of the flexible profile inlay 102 can meet various complex modeling requirements, thereby further improving the fit between the artificial ear connecting jig and the earphone to be tested.

[0050] Optionally, the surface of the metal piece 101 is coated with a Teflon coating, and the flexible profile inlay 102 is a silica gel piece or a rubber piece. The Teflon coating has good wear resistance and is not easy to corrode, which is beneficial to prolong the service life of the artificial ear connecting jig. The silica gel piece or the rubber piece is easy to process and shape.

[0051] In the embodiment, the flexible profile inlay 102 is magnetically connected with the metal piece 101. For example, the metal piece 101 is provided with an iron block, and the inside of the flexible profile inlay 102 is provided with an inlay magnet. The magnetic connection mode is convenient for replacing different flexible profile inlays 102.

[0052] Optionally, the metal piece 101 is provided with a sound leakage hole 1014 corresponding to the outlet position of the phase inverter tube of the earphone to be tested. Some earphones are provided with a phase inverter tube, and the sound leakage hole 1014 can avoid the phase inverter tube being blocked, thereby ensuring the accuracy of subsequent acoustic test results.

[0053] In the embodiment, the buckle assembly 2 comprises a rotating pressing plate 201, a rotating hook plate 202, and a torsional spring. One end of the rotating pressing plate 201 is hinged to the jig base 1, the other end of the rotating pressing plate 201 spans the placing groove 1011, and the inner side of the rotating pressing plate 201 is provided with a profile pressing block 203 for pressing the earphone to be tested. One end of the rotating hook plate 202 is hinged to the other end of the rotating pressing plate 201 through a rotating shaft 204, and the other end of the rotating hook plate 202 is provided with a hook portion 2021. The jig base 1 is provided with a clamping groove 1012 corresponding to the position of the hook portion 2021.

[0054] The torsional spring is arranged at the rotating shaft 204 to drive the clamping hook 2021 to rotate to be clamped with the clamping groove 1012 of the jig base 1. The rotating hook plate 202 is rotated upward to make the clamping hook 2021 disengage from the clamping groove 1012, and then the rotating pressing plate 201 is opened to take out the earphone to be tested.

[0055] In the embodiment, the surface of the jig base 1 for connecting with the artificial ear is a plane 1013, and the jig base 1 is fixedly provided with a jig magnet 3 for magnetically connecting with the artificial ear. Since the task of profiling the earphone to be tested is mainly performed by the artificial ear connecting jig, in order to reduce the docking difficulty between the artificial ear connecting jig and the artificial ear, the surface of the jig base 1 for connecting with the artificial ear can be designed as a plane 1013, which can not only reduce the docking difficulty between the artificial ear connecting jig and the artificial ear, but also reduce the manufacturing cost of the artificial ear.

[0056] Further, the jig base 1 is magnetically connected with the artificial ear through the jig magnet 3, which further improves the docking efficiency between the artificial ear connecting jig and the artificial ear and simplifies the docking operation.

[0057] In summary, the artificial ear connecting jig provided in the embodiment has the following advantages:

[0058] ① Universality and convenience: By using the artificial ear connecting jig, different models of earphones can be quickly adapted for acoustic testing without the need to customize artificial ears for each earphone, greatly improving the testing efficiency and convenience.
