[0020] Specifically, when in use, the speaker is installed in a position where the interior of the car is connected to the outside, and the vent 14 is connected to the outside air. When the speaker is working, the external space can be used as an amplifier to produce heavy bass. Figure 2 As shown, the vent 14 is integrally formed with a filter mesh portion 16 to prevent larger external debris from entering the outer shell 1 .

[0021] The inner shell 3, outer shell 1, and upper cover 2 are firmly connected. The space inside the upper cover 2 and inner shell 3 forms a limiting space for the magnetic circuit assembly 7, which can be firmly installed. At the same time, the structure of the inner shell 3 is also used to install and fix the sound diaphragm 8 and the centering support plate 10. Specifically, the interior of the inner shell 3 forms a hollow frame portion 12 extending downward, and the centering support plate 10 is installed at the bottom of the hollow frame portion 12.
