[0020] The following is combined with Figure 1-2 This application is described in further detail.
[0021] The embodiment of the present application discloses a speaker sealing test device.
[0022] Reference Figure 1 The speaker sealing test device includes a box body 1, a fixing part 2 and sound insulation cotton 3. The box body 1 includes a base 11 and an upper cover 12. The base 11 has an inner cavity 111. The upper cover 12 is rotatably connected to the base 11. The upper cover 12 can be rotatably closed to the inner cavity 111 of the upper cover 12. The sound insulation cotton 3 is bonded to the side wall of the inner cavity 111. The fixing part 2 is arranged in the inner cavity 111. The fixing part 2 is used to fix the speaker.
[0023] When testing the speaker, the speaker is placed in the inner cavity 111 and fixed by the fixing member 2. The sound insulation cotton 3 can absorb the sound emitted by the speaker, thereby reducing the noise emitted during the test.
[0024] A sealing strip 121 is disposed on one side of the upper cover 12 close to the base 11 , and the sealing strip 121 abuts against the upper edge of the upper cover 12 .
