[0049] Furthermore, the side wall of the cover plate 3 is provided with scale markings.

[0050] As can be seen from the above description, the scale marking makes it convenient for testers to query pressure adjustment data.

[0051] Furthermore, it also includes a baffle 7 and a quick clamp 8 provided on the baffle 7, the baffle 7 is provided with a mounting groove 71 for mounting the base 1, the mounting groove 71 is connected to the bottom surface of the baffle 7 to expose the sound outlet 12, and the quick clamp 8 presses against the base 1.

[0052] As can be seen from the above description, the baffle 7 can be considered as a partial area or the entire area of a wall panel of the test sound box for testing.

[0053] Furthermore, there are multiple quick clamps 8.

[0054] It can be seen from the above description that a plurality of quick clamps 8 can fix the base 1 more stably.
