Does a phonograph horn have a mathematical name/formula

Question

I was wanting to create a generator for making Victrola style gramophone horns in tinkercad/3d modeling software. I was wondering what the technical name for the "flower" horn style is? And does it have a mathmatical name for the equation that is used to make it. I know just about nothing about this and wanted to know if anyone did.

Answer 1

If this "horn" is shaped as a cone the best I can do is bh/3. b=r^2pi. This is a solid formula.

To get the measure of steel; use the formula for the outside; then for the inside; subtract the areas.
