Hyperbolic Horn - parametric
cults3d
Hyperbolic Horn defined by Salmon equation. Horn can be parametrized - you can change horn throat radius, cut-off frequency, T parameter, length, wall thickness, etc. You can find more details here: https://www.grc.com/acoustics/an-introduction-to-horn-theory.pdf OpenSCAD does not allow to create parametric curves so I have designed it using Autodesk Inventor. Inventor file is attached. A project using this horn: http://www.thingiverse.com/thing:1925707 You can also check my parametric Folded Horn design: https://www.thingiverse.com/thing:3133987 UPDATE 12th Jul 2019 The original ipt file does not work in Inventor 2019 - probably issue with cosh function. Attached is a new file modified for Inventor 2019.
With this file you will be able to print Hyperbolic Horn - parametric with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on Hyperbolic Horn - parametric.
