A guide bevel 11 adapted to the opening spacing of the mounting groove 8 is provided on one side of the clamping protrusion 7. The second connecting ring 5 is fixedly connected to a side close to the first connecting ring 4 with several first threaded columns 14 passing through the first connecting ring 4. The side of the first threaded column 14 is threadedly connected with a limiting nut 15 for connecting the first connecting ring 4 and the second connecting ring 5. The facing surfaces of the first connecting ring 4 and the second connecting ring 5 are provided with several arc grooves 12, and the arc groove 12 is embedded with an elastic first elastic ring 13. The side of the mounting frame 3 is provided with a wiring hole 22 and several heat dissipation holes 23.

[0031] Specific implementation method of this embodiment: When the speaker body 1 needs to be installed, the elastic mounting bracket 6 at the lower part of the mounting frame 3 is aligned with the mounting groove 8 on the connecting seat 17, and the mounting frame 3 is pressed toward the direction of the automobile sheet metal 2. The two ends of the elastic mounting bracket 6 move toward each other through the guidance of the guide bevel 11. At this time, the elastic sheet 10 and the two ends of the elastic mounting bracket 6 are squeezed and deformed. When the clamping protrusion 7 moves to the position of the clamping step 9 in the mounting groove 8, the elastic mounting bracket 6 and the elastic sheet 10 are elastic, and the clamping protrusions 7 at both ends of the elastic mounting bracket 6 are clamped with the clamping step 9. Since the elastic mounting bracket 6 and the elastic sheet 10 are elastic, when the car is bumpy during driving, The elastic mounting frame 6 is elastic and can absorb the vibration generated by the automobile sheet metal 2, which has a shock-absorbing effect on the speaker body 1. Then the external connecting wire is inserted into the mounting frame 3 through the wiring hole 22, and the connecting wire is connected to the speaker body 1. The heat dissipation hole 23 is used for air circulation to dissipate heat to the speaker body 1. The first elastic ring 13 is embedded in the arc groove 12. The first connecting ring 4 on the speaker body 1 is sleeved on the side of several first threaded columns 14 on the second connecting ring 5. The limiting nut 15 is threadedly connected to the side of the first threaded column 14, pressing the first connecting ring 4 tightly on the second connecting ring 5. At the same time, the elastic first elastic ring 13 also has a certain shock-absorbing effect.

[0034] Specific implementation method of this embodiment: through the setting of the adjustment groove 16, the speaker body 1 can be rotated in the installation frame 3, and the speaker body 1 can be rotated to facilitate the adjustment of the position of the connecting line. When the speaker body 1 and the installation frame 3 need to be disassembled, press the elastic elastic rod 19, one end of the elastic rod 19 squeezes the snap-fit ​​protrusion 7, and the snap-fit ​​protrusion 7 is disengaged from the snap-fit ​​step 9, and the elastic mounting bracket 6 can be removed from the installation groove 8, which is convenient for disassembly of the installation frame 3. The elastic rod 19 is elastic and then rebounds to the starting position. When installing the panel connected to the automobile sheet metal 2, the second elastic ring 21 is embedded in one side of the abutting ring 20, and the end of the first threaded column 14 does not exceed one side of the abutting ring 20. When the panel is installed, one side of the second elastic ring 21 is abutted against the inner wall of the panel. Since the second elastic ring 21 is also elastic, the vibration of the panel installed on the automobile sheet metal 2 on the speaker body 1 is reduced, further improving the shockproof effect of the speaker body 1.
