A threaded disc 26 is fixedly installed on the front side of the sealing rear cover 25, and the threaded disc 26 is threadedly connected with the internal thread wall 24;

[0023] When it is necessary to repair the buzzer control main board 215 and the buzzer 216 inside the main board protection housing 21, only by rotating the sealing rear cover 25 can the threaded disc 26 be driven to rotate in threaded connection with the internal thread wall 24 provided on the inner ring of the main board protection housing 21, so as to remove the overall sealing rear cover 25 and expose the rear side of the main board protection housing 21.

[0024] As Figure 3 shown in the figure, a plurality of sound outlet holes 211 penetrating through to the front side of the sound amplifying speaker panel 1 are provided on the front side of the main board protection housing 21. Main board fixing plates 212 are fixedly installed on both the left and right sides of the inner wall of the main board protection housing 21. Both of the two main board fixing plates 212 are provided with bolt holes 213 penetrating through from front to back. Bolts 214 are arranged through the inner circles of the two bolt holes 213. A buzzer control main board 215 is fixedly installed on the front sides of the two main board fixing plates 212 by the bolts 214. A buzzer 216 is arranged on the front side of the buzzer control main board 215;

[0025] The overall sound amplifying speaker receives signals through the buzzer control main board 215 fixed on the main board fixing plates 212 by the bolts 214, and emits sounds through the buzzer 216, and transmits the sounds to the front side of the sound amplifying speaker panel 1 through the plurality of sound outlet holes 211.

[0026] As Figure 4 、 Figure 5As shown in the figure, a wiring hole 221 that penetrates through to the inner cavity of the main board protection housing 21 is provided at the center of the top of the inner wall of the wiring bottom box 22. The wiring hole 221 is located below the wire fastening mechanism 23. Four fixing bolt columns 222 are fixedly installed in a rectangular array at the top of the inner wall of the wiring bottom box 22. The wire fastening mechanism 23 includes two vertical plates 231. Both of the two vertical plates 231 are fixedly installed at the bottom of the inner wall of the main board protection housing 21. The two vertical plates 231 are respectively located on the left and right sides of the wiring hole 221. A T-shaped fixing plate 232 is fixedly installed at the top of the two vertical plates 231. A wire through hole 233 that penetrates up and down is provided in the T-shaped fixing plate 232. The wire through hole 233 is located above the wiring hole 221. A threaded hole 234 that penetrates through to the rear side of the T-shaped fixing plate 232 is provided on the rear side of the inner wall of the wire through hole 233. A threaded rod 235 is threadedly installed in the inner circle of the threaded hole 234. A knob 236 is fixedly installed at the rear end of the threaded rod 235. The front end of the threaded rod 235 penetrates to the inside of the wire through hole 233 and is movably installed with a wire pressing plate 237. A rubber pad 238 is fixedly installed on the front side of the wire pressing plate 237. Limiting slide rods 239 are fixedly installed on both the left and right sides between the front and rear sides of the inner wall of the wire through hole 233. The wire pressing plate 237 is slidably connected to the outer walls of the two limiting slide rods 239.

[0027] When connecting the wire, the wire can be passed through the wiring hole 221 provided at the top of the inner wall of the wiring bottom box 22 until it extends into the inner cavity of the main board protection housing 21 and passes through the wire through hole 233, and then is soldered to the wiring terminal of the buzzer control main board 215. At this time, the knob 236 can be rotated to drive the threaded rod 235 to rotate forward in the threaded hole 234, so that the wire pressing plate 237 movably installed at the front end can stably move forward in the wire through hole 233 under the sliding limit of the two limiting slide rods 239 until the wire passing through the wire through hole 233 is clamped, and the rubber pad 238 is used to prevent the outer wall of the wire from being damaged, so that the wire is fixed, and the connection with the main board can be effectively prevented from loosening when being pulled.

[0028] Next, the working principle of the camera loudspeaker will be specifically described.

[0029] Such as Figures 1-5As shown in the figure, the overall loudspeaker receives signals through the buzzer control main board 215 fixed on the main board fixing plate 212 by using bolts 214, and emits sound through the buzzer 216. The sound is transmitted to the front side of the loudspeaker panel 1 through a plurality of sound outlet holes 211. When it is necessary to repair the buzzer control main board 215 and the buzzer 216 inside the main board protection shell 21, only by rotating the sealing rear cover 25 can the threaded disk 26 be driven to be threadedly connected and rotated with the internal threaded wall 24 opened on the inner circle of the main board protection shell 21, so as to remove the overall sealing rear cover 25 and expose the rear side of the main board protection shell 21. At the same time, when connecting wires, the wires can be passed through the wiring holes 221 opened at the top of the inner wall of the wiring bottom box 22 until they extend into the inner cavity of the main board protection shell 21 and pass through the wire through holes 233, and then be soldered to the wiring terminals of the buzzer control main board 215. At this time, the knob 236 can be rotated to drive the threaded rod 235 to rotate forward in the threaded hole 234, so that the wire pressing plate 237 movably installed at the front end can stably move forward in the wire through hole 233 under the sliding limit of the two limit slide rods 239 until the wire passing through the wire through hole 233 is clamped, and the rubber pad 238 is used to prevent the outer wall of the wire from being damaged, so that the wire is fixed, and the looseness of the connection with the main board can be effectively avoided when the wire is pulled.

[0030] The above has generally described the present invention in detail, but based on the present invention, some modifications or improvements can be made, which are obvious to those of ordinary skill in the art. Therefore, the modifications or improvements without departing from the spirit and idea of the present invention are within the protection scope of the present invention.
