Dripworks calls them "mini-jet sprayers". They are not "spinners": those throw MUCH more water per minute than a sprayer. They are not drippers or bubblers or shrublers or drippers. They spray.
Sprayers are little gadgets that have a tiny opening through which the water shoots at 30 psi, then hits some baffles so it breaks up into a spray. At higher pressures like 45 psi, they tend to put out a mist. Below 20 psi, it comes out as droplets that don't blow around (or evaporate) as much.
You can find sprayers that put out a full circle, 180 degree half-circle, a 90 degree "corner", or a "strip" of water. They should cost 10 to 30 cents each.
You can plug them directly into 1/2" mainline, or run 1/4" tubing around, and then plug one sprayer into the end of the 1/4" tubing.
One sprayer will cover a circle several feet or yards in radius, depending on the style and tbhe water pressure. They come at many different flow rates (which also depend on the pressure).
This has nicely magnified photos of several sprayer types:
Sorry, I didn't find good photos of a "system" showing mainline, 1/4" spaghetti tubing, drippers and sprayers. Often sprayers need to sit on top of a stake so the spray covers a wider circle.
