Loudspeaker

This is a model of a loudspeaker of the dynamic cone driver type, common for low and medium frequencies. The instructions walk you through modeling its electromagnetic, structural, and acoustic properties. The output from the model includes the total electric impedance and the on-axis sound pressure level at a nominal driving voltage, as functions of the frequency. This is a model of a loudspeaker of the dynamic cone driver type, common for low and medium frequencies. The instructions walk you through modeling its electromagnetic, structural, and acoustic properties. The output from the model includes the total electric impedance and the on-axis sound pressure level at a nominal driving voltage, as functions of the frequency.

The model starts out with the Small-Signal analysis from the AC/DC Module to compute the driving force and the blocked voice coil impedance. It then uses these results and adds application modes from the Acoustics Module for the acoustic-structure analysis. As an optional final modeling step, you can choose to extract and export the data needed for a 3D model.

CONSUMER PRODUCTS: Pressure waves eminating from a loudspeaker. This model couples the electromagnetics of the coil to the structural mechanics of the driver to the acoustics in and surrounding the loudspeaker.
