[0039] Further, the partition slot 32 includes a first slot and a second slot that are symmetrically arranged, and the first slot is in a straight shape, an L shape, or a concave shape.

[0040] As can be seen from the above description, the partition slot 32 will not completely cut off the ring frame structure 3, which is beneficial to ensuring the integrity of the ring frame structure 3. The specific shape of the partition slot 32 can be selected and set according to actual needs. The longer the partition slot 32 is, the wider the range where the positioning piece 21 can move.

[0041] Further, the number of the partition slots 32 on the ring frame structure 3 is greater than or equal to 3.

[0042] As can be seen from the above description, the specific number of the partition slots 32 can be selected and set according to actual needs. The more the number of the partition slots 32 is, the larger the selectable range of the distance between the magnet 23 and the micro-speaker to be tested is; the fewer the number of the partition slots 32 is, the shorter the length of the ring frame structure 3 is, which is beneficial to reducing the occupied space of the micro-speaker testing tooling for its transportation and storage.

[0043] Further, the end of the positioning piece 21 is exposed outside the outer wall of the ring frame structure 3.

[0044] As can be seen from the above description, the tester can adjust the position of the positioning piece 21 by operating the end of the positioning piece 21, which facilitates the operation of the tester.

[0045] Further, the connection part of the connecting rod 22 and the positioning piece 21 is located at the center of the positioning piece 21.

[0046] As can be seen from the above description, both regions of the positioning piece 21 on both sides of the connecting rod 22 can be locked with screws, which can prevent the magnetic boosting component from undergoing unexpected displacement and is beneficial to ensuring the accuracy of the test results.

[0047] Further, the positioning piece 21 and the connecting rod 22 are detachably connected.

[0048] As can be seen from the above description, the detachable connection between the positioning piece 21 and the connecting rod 22 facilitates the disassembly and assembly of the connecting rod 22 and the positioning piece 21.

[0049] Further, it further includes a pressure plate 4, and a conduction probe 41 is provided on the pressure plate 4, and the conduction probe 41 is used to conduct the micro speaker to be tested.

[0050] Further, one end of the pressure plate 4 is rotatably connected to the base 1, and the other end of the pressure plate 4 is detachably connected to the base 1.

[0051] Further, it further includes a baffle 5 and a support block 6 provided on the baffle 5. The other side of the base 1 abuts against the support block 6, and an avoidance groove 7 for avoiding the ring frame structure 3 is provided on the support block 6 and / or the baffle 5.

[0052] As can be seen from the above description, the ring frame structure 3 will not interfere with the baffle 5 and the support block 6.

[0053] Further, a positioning groove 51 for positioning the base 1 is provided on the baffle 5.

[0054] As can be seen from the above description, the existence of the positioning groove 51 facilitates the positioning and installation of the base 1 and the baffle 5 by the tester.
