[0019] The present invention will be further described below with reference to the accompanying drawings:

[0020] like Figures 1-4 As shown, an in-ear testing fixture for headphones consists of a main body 1, a test card set 3, and a headphone pressing assembly 4;

[0021] The test platform 2 is installed on the top surface of the main body 1. The separation and combination test card group 3 and the earphone pressing assembly 4 are installed on the test platform 2. There are two sets of separation and combination test card group 3 and earphone pressing assembly 4, which correspond one to one. The earphone pressing assembly 4 is used to press the earphone 10 on the separation and combination test card group 3 to improve its stability during the test process.

[0022] The bottom of the split-and-join test card group 3 is provided with a bottom groove 11. The split-and-join test card group 3 is composed of a fixed groove seat 31 and a rotating groove seat 32. The fixed groove seat 31 and the rotating groove seat 32 can be mounted together, or they can be separated by rotating the rotating groove seat 32, and the bottom groove 11 is exposed after rotation.

[0023] The fixed slot 31 is fixedly installed on the test platform 2, and the rotating slot 32 is rotatably installed on the test platform 2 through the plate rotating shaft 33. A rotating drive group is installed at the bottom of the rotating slot 32. The rotating drive group is installed in the bottom slot 11 to facilitate the rotation of the rotating slot 32 around the plate rotating shaft 33.

[0024] A conductive lifting cotton strip group 9 is installed in the bottom groove 11. It can be raised and lowered to contact the earphone 10, and transmit its signal through the circuit board of the main body 1 to the external display for detection and testing.
