Когда он увидел Вана Лянжэня, генерального директора компании Taizhou lainke Alarm Co., Ltd., он стоял рядом с «жестяным домом» с отверткой в руке. В жаркую погоду он сильно вспотел, а его белая рубашка промокла.
«Угадайте, что это такое?» He patted the big guy around him, and the iron sheet made a “bang”. From the appearance, “Tin House” looks like a wind box, but Wang Liangren's expression tells us that the answer is not so simple.
In the plant area of lainke, the reporter saw this “behemoth”: it is 3 meters long, the speaker caliber is 2.6 meters high and 2.4 meters wide, and it is more than enough for six strong men with a height of 1.8 meters to лечь. Matched with its shape, the power and decibels of the “defender” are also amazing. It is estimated that the sound propagation radius of the “defender” can reach 10 kilometers, covering more than 300 square kilometers. If it is placed on Baiyun Mountain, its sound can cover the whole urban area of Jiaojiang, while the coverage of general electroacoustic air defense alarm is less than 5 square kilometers, which is also one of the reasons why “defenders” can obtain invention patents .
