ABSTRACT:
This invention describes an acoustic transducer, either speaker or microphone, that uses an aerogel diaphragm or an aerogel acoustic interface made of magnetic aerogel or conductive aerogel or both. In the case of a speaker, the aerogel diaphragm is directly driven either by electromagnetic or electrostatic means to reproduce high fidelity sound. In the case of a microphone, the aerogel diaphragm is modulated by acoustic energy, and in turn, the aerogel diaphragm electromagnetically or electrostatically modulates a field detection element resulting in a high fidelity electrical audio signal output.
