This is from Lion King's website:
"Taizhou Lion King Signal Co., Ltd. is a professional company specialized in making various sirens. Our sirens, with the proven technology, superior performance and best quality, are widely used by Chinese military and police departments, and are also popular in Europe, US, Asia, Middle East nad Afreca, etc...."
Can't say I've ever seen one here, but unless they didn't paint over the sticker we might not know.
One point I was trying to make is that copying of designs by Chinese firms is a major international trade issue and has been for a while. The same goes for all sorts of intellectual property, including pirated movies and music. A guy I know involved in international trade says the Chinese are only interested in technology transfers.
Besides, what we know is that these sirens look like sirens we're familiar with. I don't think you can patent a chicken feeder enclosure, or horns attached to each port. The Big Joe copy is a little harder to explain, but for the most part a siren is a motor, shaft, rotor, stator, enclosure and controls. The Chinese don't need help on controls.
I wonder what a knockoff of a Thunderbolt would look like...
