[0026] A speaker module with a built-in speaker cavity includes a mounting frame 1, an annular groove 101 is formed on the outer surface of the mounting frame 1, a rubber pad 2 is mounted on the inner side wall of the annular groove 101, two electrode grooves 1011 are formed at one end of the inner cross-section of the annular groove 101, three threaded holes 102 are formed at equal intervals on the inner cross-section of the annular groove 101, a through hole 103 is formed on the inner side surface of the annular groove 101, a speaker unit 3 is mounted inside the annular groove 101, inside the rubber pad 2, two electrode posts 4 are mounted on the bracket of the speaker unit 3, mounting blocks 5 are symmetrically mounted on the top and bottom of both sides of the mounting frame 1, and a wiring harness 6 is connected to one side of the mounting frame 1;

[0027] A sound cavity cover 7 is installed on the back of the mounting frame 1, and a carbon fiber pad 8 is laid on the inner wall of the sound cavity cover 7. A protective cover 9 is installed on the inner bottom surface of the sound cavity cover 7, and shock-absorbing cotton 10 is installed on the inner wall of the protective cover 9.

[0028] For example, please refer to Figure 1 、 Figure 2 and Figure 3 The bracket panel on the speaker unit 3 is just inserted into the inner side of the annular groove 101, and the inner side size of the rubber pad 2 is the same as the inner side size of the rubber pad 2. Three mounting holes are opened on the outer side of the bracket of the speaker unit 3. The speaker unit 3 is threadedly connected with the threaded holes 102 on the cross section of the annular groove 101 through the hexagon socket bolts through the mounting holes. The edges of the bracket mounting holes on the speaker unit 3 are in line with the edges of the threaded holes 102. The sizes of the two electrode columns 4 on the bracket of the speaker unit 3 match the sizes of the two electrode grooves 1011, and the electrode columns 4 need to be aligned with the electrode grooves 1011 when installing the speaker unit 3. 11, and after the position is aligned, press lightly, and the two electrode columns 4 can be snapped into the inner side of the electrode groove 1011. The inner wall of the electrode groove 1011 is a metal conductive material, which can be used as a connection medium for the electrode column 4. One end of the wiring harness 6 is provided with a plug for inserting into the audio source device, and the other end of the wiring harness 6 is connected to the mounting bracket 1 and then extends into the interior of the mounting bracket 1 to be connected to the metal conductive materials on the inner walls of the two electrode grooves 1011 respectively.
