[0025] In order to explain the technical content, achieved objectives and effects of the present invention in detail, the following is an explanation in conjunction with the implementation modes and the accompanying drawings.

[0026] Please refer to Figures 1 to 3 The utility model provides a test tool, which includes a tool body 1, a card slot 2 is provided on the tool body 1, a first through hole 21 and a water flow channel 3 are provided at the bottom of the card slot 2, and a second through hole 31 is provided at the bottom of the water flow channel 3, wherein the first through hole 21 and the second through hole 31 penetrate the tool body 1 in the height direction, and the hole height of the first through hole 21 is greater than the hole height of the second through hole 31.

[0027] The structural principle / working principle of the utility model is briefly described as follows: the test fixture can be used for real water testing of micro speakers. Before the real water test, the front cavity of the micro speaker can be placed downward into the card slot 2, so that the micro speaker can be quickly fixed to the fixture body 1 for subsequent testing. When performing a real water test, water can be first injected through the first through hole 21 (i.e., the water injection hole), and the water flows into the card slot 2 through the first through hole 21. The water flows and submerges the speaker, and then pressurization is performed to complete the test. After the test, the water in the card slot 2 needs to be drained out. At this time, the water in the card slot 2 can be drained out through the second through hole 31 (i.e., the drain hole).

[0028] From the above description, it can be seen that the beneficial effect of the utility model is that the utility model is provided with a water flow trough 3 in the card slot 2, and the water accumulated in the card slot 2 can quickly flow into the second through hole 31 through the water flow trough 3, and then flow out through the second through hole 31 to achieve the drainage effect. On this basis, the hole height of the first through hole 21 is made greater than the hole height of the second through hole 31, that is, the second through hole 31 used for drainage is lower in terrain on the tooling body 1 than the first through hole 21 used for water injection. Therefore, the principle that water flows to a lower place is utilized, so that after the real water test, the water can be quickly drained out to increase the drainage speed. In addition, the test tooling is provided with a card slot 2, through which the micro-speaker to be tested in real water can be quickly and effectively fixed in place, and the sealing is good, which is convenient for subsequent real water testing.

[0029] Furthermore, in the test fixture described in the present invention, the width of the slot of the water flow channel 3 gradually increases along the first direction close to the first through hole 21 .

[0030] In the above technical solution of the utility model, the slot width of the water flow channel 3 gradually increases along the first direction close to the first through hole 21, that is, the slot width of the water flow channel 3 at the end close to the first through hole 21 is greater than the slot width at the end away from the first through hole 21. In actual use, water flows into the water flow channel 3 from the end with a larger slot width, gradually flows into the bottom of the water flow channel 3, and flows out through the second through hole 31. Increasing the slot width of the water flow channel 3 at the end close to the first through hole 21, and then increasing the inflow channel path of the water flow channel 3, can quickly guide the water injected into the card slot 2 from the first through hole 21 into the second through hole 31 in the water flow channel 3.

[0031] Furthermore, in the test fixture described in the present invention, the water flow channel 3 is provided with an inclined groove 32 in a direction close to the first through hole 21 , and the groove depth of the inclined groove 32 gradually decreases along the first direction close to the first through hole 21 .

[0032] In the above technical solution of the present invention, the depth of the inclined groove 32 is gradually reduced along the first direction close to the first through hole 21, that is, the bottom of the inclined groove 32 is an inclined surface, through which, by utilizing the principle that water flows to lower places, the water flow injected from the first through hole 21 can be quickly introduced into the bottom of the water flow groove 3 through the inclined surface, and then flow into the second through hole 31.

[0033] Furthermore, in the test fixture described in the present invention, the extending direction of the inclined surface of the inclined groove 32 is set at an angle to the first direction.

[0034] In the above technical solution of the utility model, the extending direction of the inclined surface of the inclined groove 32 is set at an angle to the first direction, so that water can flow into the first through hole 21 through the inclined groove 32 .

[0035] Furthermore, in the test fixture of the present invention, the shapes of the axial cross-sections of the first through hole 21 and the second through hole 31 are both circular.

[0036] In the above technical solution of the utility model, by setting the shapes of the axial cross-sections of the first through hole 21 and the second through hole 31 to be circular, water can be effectively injected through the first through hole 21 and flow out through the second through hole 31 .

[0042] Furthermore, in the testing tool described in the present invention, the sides of the tool body 1 extending along the second direction are all provided with protruding portions 5 protruding outwards.

[0043] Furthermore, in the test tool described in the present invention, the first direction is the length direction of the tool body 1 , and the second direction is the width direction of the tool body 1 .

[0044] In the above technical solution of the utility model, the two sides of the tool body 1 extending along the first direction are respectively provided with inwardly recessed portions, and the two sides of the tool body 1 extending along the second direction are respectively provided with outwardly protruding portions 5.
