Electroacoustics: Electrodynamic Transducer

This lecture covers the physical phenomena behind electrodynamic transduction, focusing on electromechanical analogies and coupling equations. It explains the operation of electromagnetic transducers, the induced voltage in conductors, and the coupling between electrical and mechanical variables. The lecture also discusses the design and efficiency of electrodynamic transducers, including loudspeakers, and presents equivalent electrical diagrams and mechanical models for transducers.
