Interior Lumped Speaker Boundary

The is used to model a loudspeaker (dust cap, cone, and surround assembly) using a lumped representation with a coupling to an interface. The mechanical and electric properties of the speaker are described through a Thiele-Small representation and associated lumped parameters. Add this node from the submenu. The interior version of the Lumped Speaker Boundary includes the effects of the fluid domains on both sides of the speaker boundary explicitly.

Define how the (projected) of the speaker is computed by selecting either (the default) if all boundaries are present, or if only the speaker surface is partially represented. Enter the Ascale (default is 1). The settings are required in order to compute the effective area of the speaker.

Define the eax by selecting (the default) or . For the automatic option the axis is computed as the average of the surface normals, this option is valid if a full speaker surface is selected. The user defined option should be used if the speaker surface is only partially represented.

For the option select if necessary. The axis orientation can be visualized by plotting the axis components acpr.ilsb1.e_axx, acpr.ilsb1.e_axy, and acpr.ilsb1.e_axz. (using the proper item and physics scope).

This section gives information about the state of coupling/connection to an Electrical Circuit interface. If the is not connected the text text will be displayed. Once connected a reference with a tag to the associated node, in the Electrical Circuit interface, is displayed.
