I am designing a drone to play sound. I can 3D print the horn. Would like suggestions for some light weight PA horn drivers. Any search I do for horn drivers only shows high frequency tweeter drivers. I need mid range for voice signal.
Would something like this work? It is a neodymium speaker designed for portable devices.AIYIMA 2Pcs Full Range Portable Speaker 2 INCH 4 Ohm 16W Sound Music Neodymium Audio Speaker Driver For Computer Loudspeaker DIY - Aliexpress
Or this? TEAX32C30-4/B | Tectonic Round Audio Exciter, 30W nom, 30W max, 4Ω | RS Components

First one yes, probably. Second one, no not at all. But a horn to cover vocal frequencies is going to be bigger than you think.
What's the maximum payload your drone can handle? Unless it's a big drone, you're probably better off with a fullrange driver.
Lightest vocal range horn drivers are about 5 lbs. Faital Pro 3FE22 is about as sensitive as your going to find in a small driver. Weighs in at half a pound. Will be considerably louder than your typical bluetooth speaker driver. A true horn is space prohibitive but you can do a shallow waveguide. Will be better than nothing.

I will have and experiment with the Faital Pro 3FE22. What is special about a vocal range horn driver compared to a standard full range driver? I took a horn apart, it was like a treble driver, but the diaphragm was more rigid. I don't really understand the effect of things like the diaphragm stiffness and also the reason the throat diameter is narrower than the diaphragm. Should I hack a Faital Pro 3FE22 to be more like a vocal horn driver?
