Abstract

This report describes the development of a novel moving magnet transducer. Our team’s generate quality bass while maintaining the slimmest possible profile. In our design current flows through coils that are wound around opposing arms of the low carbon-steel stator. The current induces a magnetic flux in the stator that causes it to act as an electromagnet. The permanent magnets centered in our design oscillate up and down as they interact with the electromagnet. These magnets are bonded to the speakers’ cone, so as they oscillate, the cone oscillates and sound becomes audible. The final transducer measured 0.80” tall with a 2.94” diameter and produced 1.24 N/Amp force. A breakdown of our design process, manufacturing process, and operational performance results are in our report.
