If you’re interested in MEMS-acoustic modelling and want to learn how to provide your colleagues and customers with software tools to collaborate and optimise their designs, then register to watch this webinar.
In this presentation, we discuss how to build a fully coupled, MEMS-acoustic interaction model of electrostatic headphones in COMSOL Multiphysics. The dynamics of an electrostatic speaker is a true multiphysics phenomenon that involves the nonlinear relationship of structural mechanics, electrostatics, electrical conduction, and acoustics. Many interrelated design elements affect the device’s frequency response and the user’s listening experience.
You will also learn about how Dr Brett Marmo from Xi Engineering Consultants used simulation apps and COMSOL Server to create a more streamlined and interactive design process. Dr Marmo will demonstrate how he designed a graphic user interface based on an electrostatic headphone model using the Application Builder in COMSOL Multiphysics, which enabled his clients without modelling experience to virtually test proposed design modifications. You will also hear about how clients were able to access the simulation app using COMSOL Server installed on a virtual private cloud and test the size and thickness of device components, their elastic and electric properties, and the thickness and aperture size of the wire mesh.
