Design of an advanced retractable multi-speaker headphone

摘要

This study sets up a complete mathematical model of a headphone. The whole model integrated circuit systems, mechanical systems and acoustic systems. By transforming all the systems to mechanical systems, we use the equivalent circuit method to derive the governing equation. From comparing it with different structure analysis, this study proposes an improved stucture design for better sensitivity and designing the stucture as a retractable headphone.
