Comparing Sound Radiation from a Loudspeaker with that from a Flexible Spherical Cap on a Rigid Sphere

Modeling a real loudspeaker as a spherical cap on a rigid sphere is often more useful than the conventional model of a loudspeaker as a rigid piston in an infinite baffle. This new model can predict such parameters as sound pressure, baffle-step response, sound power, directivity, and the acoustic center. This research extends earlier work without depending on a more complex scheme. Future work using this approach will show the relevance to other topologies.
