[0024] See also Figure 1-4 The two-in-one speaker includes a shell base 1 and a shell 2 that are docked with each other, and also includes a control panel 5, an AVAS speaker 7, and a whistle speaker 8. The upper end of the shell 2 is penetrated by a mounting groove 3 and a conical sound amplification sleeve 4 that are connected to the inner cavity. The AVAS speaker 7 is installed in the mounting groove 3, and the control mainboard 5 and the whistle speaker 8 are both arranged in the shell base 1. The whistle speaker 8 movably penetrates the conical sound amplification sleeve 4. The bottom of the shell base 1 is provided with a wiring port 6 that is electrically connected to the control mainboard 5.

[0025] Among them, the four corners of the shell base 1 and the shell 2 are all provided with outer grooves 101, and the four corners of the shell base 1 are also reserved with connection holes 102 for convenient bolt penetration. After the shell base 1 and the shell 2 are clamped, the whole can be fixed to the specified position of the vehicle for installation by using bolts to penetrate the outer connection holes 102 of the shell base 1.

[0026] Among them, an annular ridge 103 is provided at the upper end of the shell base 1, and an annular groove 201 is provided at the bottom of the shell 2 and is clamped to the annular ridge 103. A rubber sealing gasket is provided on the inner wall of the annular groove 201, and the annular groove 201 contacts the outer wall of the annular ridge 103 through the rubber sealing gasket. After the shell base 1 and the shell 2 are docked, the annular ridge 103 at the upper end of the shell base 1 is clamped to the annular groove 201 at the bottom of the shell 2, and the rubber sealing gasket is used to increase the friction stability of the clamping and the sealing effect, so that the shell base 1 and the shell 2 are stably connected.

[0027] Among them, a mounting plate 701 is arranged on the outside of the AVAS speaker 7, and a mounting seat 801 is arranged on the outside of the whistle speaker 8. The mounting plate 701 and the outer shell 2, as well as the control panel 5, the mounting seat 801 and the outer shell base 1 are all detachably fixedly connected by fasteners.
