Virtual ALTI on June 15, 2021: Multiphysics Simulation of a Low Frequency Horn Loudspeaker

On June 15, 2021, the virtual ALTI EXPO 2021 took place.

Mvoid and Funktion One participated with a joint presentation on Multiphysics Simulation of a Low Frequency Horn Loudspeaker

Using a reference project, James Hipperson, Acoustic Design Engineer Funktion One, Dr. Alfred J. Svobodnik and Tommaso Nizzoli, both Mvoid Group,  gave insight into advanced modeling  procedures for professional horn-loaded bass loudspeakers.

They explained the following milestones of the virtual development process:

– CAD based geometry definition
– Physics attributes of transducer and enclosure
– Fully coupled multiphysical analysis
– Electromagnetics
– Structural dynamics
– Acoustics
– Postprocessing

Alfred, James  and Tommaso showed that this approach predict correctly a non-trivial design/geometry, purely from the geometry model, in the sense that it covers both resonant and horn loading effects.

A special focus was given on postprocessing following the paradigm of a virtual measurement resulting in high resolution directivity patterns for further analysis in array modeling and room acoustics predictions.

A live-demo and information on validation of results by means of measurements completed the presentation.
