This article explores Polyvinylidene Fluoride Film (PVDF), and how it is used in various transducers for headphones, microphones and loudspeakers. The first part of this article explored polyvinylidene fluoride (PVDF) piezoelectric film loudspeakers. Now, our exploration of this technology focuses on its many other successful applications — from headphones, microphones, to guitar pickups, and more recent developments in PVDF electro-active polymer (EAP) products for haptic vi

In this article, the history of Polyvinylidene Fluoride Film (PVDF), a piezoelectric polymer used in various transducers, is revisited.

In this article, Mike Klasco provides an introduction to the voice capture, signal processing and voice recognition challenges. Voice processing and recognition leading to the development of voice-based personal assistants is one of the decade’s greatest achievements and provides a unique opportunity for the audio industry. Audio product development, and audio magazines for that matter, have traditionally been all about music reproduction, but recently voice has taken center
