Embodiment 1

[0038] The structural schematic diagram described in this embodiment is shown in Figure 1 to Figure 17 shown.

[0039] For the built-in system described in this embodiment, see Figure 8 and Figure 9 . A camera 1 is installed in the center of the photoelectric panel 4 of the built-in system, and the outside of the camera 1 is a light shielding ring 2, which is used to prevent the interference of the small LED module 3 on the outside of the camera to the work of the miniature camera 1. Multiple small LED modules 3 can be combined with visible light, infrared light or laser according to the needs of the system work. The outer circle of the photoelectric panel 4 is synchronized with the aluminum pad 6 , and the slots 5 on both sides of the photoelectric panel 4 are docked with the slots 7 of the aluminum pad 6 . The photoelectric panel 4 is closely mounted on the aluminum pad 6 .

[0040] The outer circle of the circular aluminum pad 6 of the built-in system described in t...

Abstract

The invention discloses a sound, light and electric eye alarm device, which comprises a built-in system, a double magnetic steel magnetic circuit and a cast aluminum wing-shaped basin frame. The built-in system consisting of photoelectric board, aluminum pad and copper rod is installed under the transparent dust cover of the dynamic speaker and in the axial center of the magnetic circuit; the photoelectric board is installed with a camera, light shielding ring and LED module; the photoelectric board is located on top of the aluminum pad noodle. The magnetic circuit of the double magnet steel is composed of main magnet steel, auxiliary magnet steel, magnetic column and magnetic conduction bowl, and a hole is opened in the center of the magnetic circuit. The combination of the cast aluminum airfoil frame and the copper rods and aluminum pads of the built-in system is a high-efficiency conduction heat sink for photovoltaic panels. The space reserved between the built-in system and the magnetic circuit and the threading hole of the airfoil basin frame are passages for the multi-strand wiring harness of the photoelectric panel; the invention makes the loudspeaker an all-weather monitoring and police device.

Description

technical field [0001] The invention discloses a sound, light and electric eye warning device, which belongs to the technical field of loudspeakers. Background technique [0002] According to the reports of crowd stampede accidents around the world, they all have one thing in common: because of the crowded and noisy environment, the police officers are caught in the crowd, unable to approach the accident site, unable to guide and guide. At night, it is even more impossible to obtain evidence and warn. If there is a small-scale equipment that integrates centralized shouting, lighting, and camera evidence collection, which can be carried by police officers or loaded into unmanned aircraft, it will help prevent the occurrence of stampede accidents, or it can be effectively dealt with at the time of the incident. With the miniaturization of LED packaging and the miniaturization of cameras, it will become possible to realize the integration of small-scale equipment for shouting,...
