【Embodiment】

For ease of being better understood from the purpose of this utility model, structure, feature and effect etc., in conjunction with accompanying drawing and specifically The utility model is described in further detail for embodiment.

One kind broadcast loudspeaker 1, including cabinet 11, top board 12 and base plate 13.

Provided with memory module (not shown) in the cabinet 11, trigger control module (not shown), signal amplification module is (not Diagram), power module (not shown) and electroacoustic component (not shown).The memory module is used to store alert audio；It is described to touch Hair control module is used to receive coordinated signals signal, and calls the corresponding alert audio in memory module；The signal amplifies mould Block is used to amplify the alert audio or other audio signals of input；The electroacoustic component is used for the signal amplification module Signal after amplification is converted to voice signal and played out；The power supply module is used for above-mentioned module for power supply.

Fig. 1 is refer to, the top board 12 is provided with the first screwed hole 121 and the first fixed part 122.First screwed hole 121 are used to be connected with fixture 2, and the broadcast loudspeaker 1 is fixed on building；First fixed part 122 is used for will The top board 12 is fixed with the cabinet 11 mutually assembling.

Fig. 2 is refer to, the base plate 13 is provided with control panel, and the control panel is provided with control interface 130, volume adjusting Knob 131, the second screwed hole 132, the second fixed part 133 and power line 3.The volume adjustment knob 131 is used to adjust described Broadcast loudspeaker broadcast sound volume.Second screwed hole 132 is used to be connected with fixture 2, and the broadcast loudspeaker 1 is fixed on On building.Second fixed part 133 is used to fix the base plate 13 and the cabinet 11 mutually assembling.The power line 3 are connected with power module, and the access 220V/AC power supplys of power line 3, are other module for power supply by power module.

Fig. 1 is refer to, the control interface 130 is water-proof connector, and the water-proof connector is provided with waterproof apron 1302, Terminal 1303 and housing 1301, the terminal 1303 are located inside the housing 1301.Terminal 1303 described in the present embodiment is ten Two (such as No. Fig. 1 to No. 12 pins), including 7 coordinated signals signal terminals, 2 control signal input and 3 audios Signal terminal.

The coordinated signals signal terminal and trigger control module connection, the coordinated signals signal terminal are provided with 6 Root access terminal (No. 1 to No. 6 pin) and 1 public terminal (No. 7 pins), are corresponded to therewith, and the memory module storage 6 is reported for the first time Alert audio.When No. 1 pin and short-circuit No. 7 pins, triggering control mould calls the 1st first alert audio in memory module；Draw when No. 2 When pin and short-circuit No. 7 pins, triggering control mould calls the 2nd first alert audio in memory module；When No. 3 pins and No. 7 pins are short Lu Shi, triggering control mould calls the 3rd first alert audio in memory module；When No. 4 pins and short-circuit No. 7 pins, triggering control Mould calls the 4th first alert audio in memory module；When No. 5 pins and short-circuit No. 7 pins, triggering control mould calls memory module In the 5th first alert audio；When No. 6 pins and short-circuit No. 7 pins, triggering control mould calls the 6th first alarm sound in memory module Frequently；Make the broadcast loudspeaker that there are 6 road coordinated signals signals, play 6 kinds of different alarm condition linkage voices.

The control signal input sub (No. 8, No. 9 pins) is used to input 485 control signals, 485 control signal The voice that the alert audio can be edited can also be to multiple broadcast loudspeakers while editing setting.Or, by computer audio frequency File, 485 control signals inputted by No. 8, No. 9 pins are stored in the memory module.
