[0012] Figure 2 It is a disassembly schematic diagram of the utility model. Implementation

[0013] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0014] The technical solution specifically implemented in this utility model is:

[0015] like Figure 1 and Figure 2 As shown, a car engine sound speaker with a connection protection function includes a speaker body 1 and a mounting seat 2, the bottom surface of the speaker body 1 is provided with a plurality of terminals 3, the mounting seat 2 is provided with corresponding terminal grooves 4, the bottom surface of the speaker body 1 is provided with a downwardly extending protective enclosure 5, the protective enclosure 5 surrounds the periphery of all the terminals 3, the height of the protective enclosure 5 is greater than or equal to the height of the terminals 3, the side of the protective enclosure 5 is provided with a screw hole 6, the mounting seat 2 is provided with a corresponding enclosure groove gap 7, the outer side of the mounting seat 2 is provided with a through hole 8 connected to the enclosure groove gap 7, the through hole 8 corresponds to the screw hole 6, a pin 9 is passed through the through hole 8 and the screw hole 6, and the end of the pin 9 is threadedly connected to the screw hole 6.

[0016] The inner wall of the protective enclosure 5 is provided with a sealant layer 10, the cross-section of the sealant layer 10 is larger at the top and smaller at the bottom, and the contact surface between the groove gap 7 and the sealant layer 10 is relatively inclined; the sealant layer 10 can make the protective enclosure 5 and the groove gap 7 fit more closely, and the sealing effect is good.

[0017] The upper surface edge of the mounting seat 2 is provided with a calibration mark 11 corresponding to the through hole 8 ; when the speaker body 1 is inserted into the mounting seat 2 , the through hole 8 of the mounting seat 2 is aligned with the screw hole 6 of the protective panel 5 .
