Electroacoustic transducers

Abstract

A microphone is an electroacoustic transducer. The acoustic input is nothing more than sound waves. These interact with a diaphragm, to excite motion in solid bodies. The mechanical system interacts electrically to create an electrical signal. There are several techniques in which motion may be turned into an electrical signal. This paper will introduce a technique where a sound wave moves a foil near a coil, changing the coil's inductance, producing a time-varying voltage signal.
