Loudspeaker Driver in a Vented Enclosure
Application ID: 2312
This model of a boxed loudspeaker lets you apply a nominal driving voltage and extract the resulting sound pressure level in the outside room as a function of the frequency. The sensitivity, both on-axis and spatial, is determined as function of frequency. These are some of the most important design parameters for a loudspeaker.
The electromagnetic properties of the driver are supplied from the Loudspeaker Driver model (available with the AC/DC Module). The model uses the Acoustic-Shell Interaction, Frequency Domain multiphysics interface and therefore requires the Structural Mechanics Module.
This model is included as an example in the following products:Acoustics Module
however additional products may be needed to reproduce it. This example may be created and run using components from the following product combinations:
The combination of COMSOL® products required to model your application depends on several factors and may include boundary conditions, material properties, physics interfaces, and part libraries. Particular functionality may be common to several products. To determine the right combination of products for your modeling needs, review the Specification Chart and make use of a free evaluation license. The COMSOL Sales and Support teams are available for answering any questions you may have regarding this.
