The side of the speaker bracket 5 away from the diaphragm 8 is adhered with a dustproof cloth 11, which achieves the effect of dustproofing the speaker bracket 5, avoids dust adhering to the speaker bracket 5, and affects the clarity of sound transmission, and improves the practicality of the device. The surface of the upper shell 1 is fixedly connected with an arc plate 12, and a groove is opened on the surface of the arc plate 12. The inner surface of the groove of the arc plate 12 is fixedly connected with a filter screen 14, and the arc surface of the arc plate 12 is fixedly connected to the U-shaped The plate 15 is rotatably connected with a rotating rod 16 in the U-shaped plate 15, and the arc surface of the rotating rod 16 is fixedly connected with a cover plate 17. A snap-in hole is provided on the surface of the arc plate 12, and a snap-in plate 18 is slidably connected to the inner surface of the snap-in hole of the arc plate 12. The snap-in plate 18 is made of a soft material, and the snap-in plate 18 is fixedly connected to the surface of the cover plate 17, so as to achieve the effect of protecting the diaphragm 8, and avoid mosquitoes and dust adhering to the diaphragm 8 when the diaphragm 8 is used outdoors for a long time, which corrodes and damages the diaphragm 8, thereby affecting the timbre of the speaker and improving the practicability of the device. The inner surface of the snap-in plate 18 is fixedly connected with a spring 13, and under the action of the spring 13, the stability of the snap-in plate 18 in the snap-in hole of the arc plate 12 is improved. The arc surface of the rotating rod 16 is sleeved with two torsion springs 19, and the two ends of the torsion spring 19 are fixedly connected to the U-shaped plate 15 and the cover plate 17 respectively. Under the force of the torsion spring 19, the cover plate 17 is automatically opened and maintained at a certain angle, thereby improving the practicality of the device. A vent hole is provided on one side of the lower shell 2, and a waterproof breathable membrane 20 is adhered to the inner surface of the vent hole of the lower shell 2. By providing the waterproof breathable membrane 20, the upper shell 1 and the lower shell 2 are ventilated and the water vapor in the air is prevented from entering the interior of the upper shell 1 and the lower shell 2, thereby improving the practicality of the device. The material of the rubber pad 4 is EVA foam, which achieves the effect of heat insulation and cold resistance, and can reduce noise, thereby improving the practicality of the device.

[0028] Working principle: first, the internal parts of the upper shell 1 and the lower shell 2 are installed in an integrated manner, then the connecting line 10 is electrically connected to the monitoring device 2, and then the integrated speaker composed of the upper shell 1 and the shell 2 is installed on the monitoring device, and the waterproof breathable membrane 20 is adhered to the vent hole of the lower shell 2.

Secondly, when it is necessary to protect the diaphragm 8, the snap-on plate 18 is pressed, and the snap-on plate 18 drives the spring 13 to be compressed, so that the snap-on plate 18 can slide in the snap-on hole of the arc plate 12. When the snap-on hole of the arc plate 12 releases the limit on the snap-on plate 18, the cover plate 17 is released under the action of the torsion spring. It opens automatically and maintains a certain angle. At this time, the filter screen 14 is placed in the groove of the arc plate 12, and then the cover plate 17 is pushed. The cover plate 17 drives the rotating rod 16 to rotate in the U-shaped plate 15 until the clamping plate 18 slides into the clamping hole of the arc plate 12 and is fixed. The cover plate 17 is fixed, which avoids the diaphragm 8 from being used outdoors for a long time, mosquitoes and dust adhering to the diaphragm 8, corroding and damaging the diaphragm 8, thereby affecting the timbre of the speaker and improving the practicability of the device. Through the above series of devices, the sound transmitted from the speaker of the monitoring equipment becomes clearer and cleaner, the recognition of the listening sound is higher, and the sound pressure is greatly improved. At the same time, the low frequency is fuller, the sound is more magnetic, and the sound has emotional color, which makes each other's hearts closer.
