Identification of Frequency-Dependent Loudspeaker Cone Material Parameters Using Inverse FEM

This thesis uses inverse FEM and COMSOL Multiphysics to identify the frequency-dependent stiffness and damping of a polypropylene loudspeaker cone from impedance and sound pressure measurements.

Numerical analysis of an acoustic leaky wave antenna for underwater applications

This thesis presents a COMSOL Multiphysics simulation of an underwater acoustic leaky wave antenna, coupling pressure acoustics and solid mechanics to study frequency-dependent beam steering, directivity and radiation efficiency.

Omnidirectional loudspeaker driver with sectors membrane

This thesis presents a COMSOL Multiphysics simulation of a Walsh-type omnidirectional loudspeaker driver, coupling magnetic fields, solid mechanics and pressure acoustics to study sectorized membrane materials and acoustic response.

Acoustical Behavior of an Air Motion Transformer AMT Transducer

This thesis presents a COMSOL Multiphysics simulation of an Air Motion Transformer transducer, coupling acoustics, structural mechanics and magnetic fields to study its vibroacoustic and electroacoustic behaviour.
