Hyperbolic Horn - parametric

thingiverse

The Hyperbolic Horn is defined by the Salmon equation, enabling it to be parametrized and modified in various ways. The horn's throat radius, cut-off frequency, T parameter, length, wall thickness, and other characteristics can all be adjusted. For more detailed information on horn theory, visit https://www.grc.com/acoustics/an-introduction-to-horn-theory.pdf. As OpenSCAD does not support parametric curves, I designed the Hyperbolic Horn using Autodesk Inventor. The Inventor file is included for reference. This design has been used in a project, which can be viewed at http://www.thingiverse.com/thing:1925707.

UPDATE July 12th, 2019 The original Inventor file appears to be incompatible with Inventor 2019, likely due to an issue with the cosh function. A revised file has been attached, modified to work with Inventor 2019.
