Speakers: Parts Is Parts - High-Polymer Film, The Lost Speaker Technology (Part 1)
This article explores Polyvinylidene Fluoride Film (PVDF), a piezoelectric polymer used in various transducers for headphones, microphones and loudspeakers. It seems that the audio engineering community at large is either not familiar with PVDF film or misunderstands PVDF piezoelectric film technology. Hopefully, this article will serve as an introduction (or reintroduction) to the technology. This article was originally published in audioXpress April 2013.
