[0020] As can be seen from the above description, the beneficial effects of this utility model are as follows: This BASS powder testing fixture has a simple structure. After filling the receiving cavity 11 of the base 1 with BASS powder 3, the upper cover 2 of the speaker unit 4 to be tested is placed on the base 1 to conduct the test. This determines whether the type of BASS powder 3 filled in the receiving cavity 11 can make the performance of the speaker module meet the design requirements, and verifies whether the amount of BASS powder 3 filled in the receiving cavity 11 can make the performance of the speaker module meet the design requirements. During the entire testing process, the operation of the tester is very simple, and the BASS powder 3 is easy to pick up and put away, which helps to improve testing efficiency and reduce testing costs.

[0021] Furthermore, the outer peripheral wall of the base 1 is provided with a vent hole 12 that communicates with the receiving cavity 11.

[0022] As described above, the housing cavity 11 is connected to the outside through the vent hole 12, which can prevent the air pressure inside the housing cavity 11 from being too high during the downward vibration of the diaphragm assembly of the speaker unit 4, thus affecting the downward vibration amplitude of the diaphragm assembly and causing inaccurate test results.

[0023] Furthermore, the connection between the vent 12 and the receiving cavity 11 is located at the upper part of the receiving cavity 11.

[0024] As can be seen from the above description, the connection between the vent 12 and the receiving cavity 11 is located at the upper part of the receiving cavity 11, which can improve the phenomenon of BASS powder 3 blocking the vent 12 and facilitate smooth ventilation between the receiving cavity 11 and the outside.

[0025] Furthermore, the mounting window is provided with an annular step 21, and a second sealing element 6 for contacting the speaker unit 4 is provided on the step surface of the annular step 21.

[0026] As described above, the second seal 6 is used to seal the gap between the speaker unit 4 and the annular step 21.

[0027] Furthermore, the upper cover 2 is provided with a first magnetic suction member 22, and the base 1 is provided with a second magnetic suction member 13 that magnetically engages with the first magnetic suction member 22.

[0028] As can be seen from the above description, the magnetic connection between the upper cover 2 and the base 1 allows the upper cover 2 and the base 1 to more fully press against the first sealing element 5, thereby improving the sealing effect of the receiving cavity 11 and helping to ensure the accuracy of the test results.

[0029] Furthermore, the upper cover 2 is provided with a first anti-foolproof structure 23, and the base 1 is provided with a second anti-foolproof structure 14 that cooperates with the first anti-foolproof structure 23.

[0030] As can be seen from the above description, the top cover 2 and the base 1 adopt a foolproof design, which allows the top cover 2 to be smoothly and accurately placed on the base 1.

[0031] Furthermore, the upper cover 2 is provided with an electrical plug 7 for supplying power to the speaker unit 4 located in the mounting window, and the base 1 has a clearance groove 15 for avoiding the electrical plug 7.

[0032] As described above, the external power supply powers the speaker unit 4 through the electrical plug 7, which facilitates the power-on of the speaker unit 4 and helps to improve the testing efficiency to a greater extent.

[0033] Furthermore, the clearance groove 15 is connected to the peripheral wall of the base 1.

[0034] As can be seen from the above description, the clearance groove 15 connects to the peripheral wall of the base 1, which can prevent the base 1 from blocking the wiring of the electrical plug 7, making it convenient for testers to operate.

[0035] Furthermore, the upper cover 2 is also provided with a wiring groove 24 that connects to the mounting window, and the connection wiring between the electrical plug 7 and the speaker unit 4 is located in the wiring groove 24.

[0036] As can be seen from the above description, the wiring groove 24 can effectively accommodate the connecting wires and ensure that the top cover 2 and the base 1 can achieve planar contact.

[0037] Furthermore, the base 1 is provided with a pick-up and put-down groove 16 on its peripheral wall. The pick-up and put-down groove 16 is connected to the top surface of the base 1, and a part of the upper cover 2 is located above the pick-up and put-down groove 16.

[0038] As can be seen from the above description, the presence of the pick-and-place slot 16 facilitates the test personnel in picking up and placing the top cover 2.
