Lumped Loudspeaker Driver
Model ID: 12295
This is a model of a moving-coil loudspeaker where a lumped parameter analogy represents the behavior of the electrical and mechanical speaker components. The Thiele-Small parameters (small-signal parameters) serve as input to the lumped model, which is represented by an Electric Circuit physics. The lumped model is coupled to a 2D axisymmetric Pressure Acoustics model describing the surrounding air domain (above and below the speaker cone). The output from the model includes, among many things, the speaker sensitivity, the impedance, and the radiated acoustic power. The results are compared with an analytical solution based on the flat piston approximation.
The model requires the Acoustics Module and the AC/DC Module.
