Knowles Redefines Premium Sound with New Dual-Diaphragm Balanced Armature

With the new dual-diaphragm BA as a defining ingredient, Knowles has also partnered with Campfire Audio and Astell&Kern to create a groundbreaking, premium earphone: Pathfinder.

ITASCA, Ill., May 16, 2022 — Knowles Corporation (NYSE: KN), a market leader and global provider of advanced micro-acoustic microphones and speakers, audio solutions, and high-performance capacitors and RF products, presents its new dual-diaphragm balanced armature (BA), a revolutionary advancement in the world of BA technology. The patented dual-diaphragm technology allows the BA to achieve high output levels while maintaining a small footprint. The design incorporates two chambers, each housing its own diaphragm and drive rod actuated by a single coil. The combined output of the two chambers provides a warm, clear sound and more natural quality for premium earphones and discreet hearing devices.

“Significant design and manufacturing challenges had to be overcome to create a BA with two self-contained diaphragms driven by a single coil and armature,” describes Jon Kiachian, Vice President and GM of Knowles Hearing Health Technologies. “Derived from Knowles’ 75-year track record of innovation, the dual-diaphragm BA delivers best-in-class output for its size; there’s no other BA like it.”

To make the most of this technology’s potential, Knowles has partnered with two of the most trusted and experienced names in HiFi audio: Campfire Audio and Astell&Kern. With the new dual-diaphragm BA as a defining ingredient, the companies have come together to create a groundbreaking, premium earphone: Pathfinder.

“The new dual-diaphragm BA from Knowles signals a game-changing shift in the technology,” said Campfire Audio VP Caleb Rosenau. “We’re proud to be the first manufacturer to utilize this all-new BA with our design of the Pathfinder for Astell&Kern and can say that this driver technology is set to be a defining element delivering a new level of performance and clarity in the next generation of Campfire Audio earphone designs.”

Experience the premium sound quality and exceptional comfort of Astell&Kern’s Pathfinder at HIGH-END Munich May 19-22, 2022.

The Knowles dual-diaphragm BA will be a continued feature of Campfire Audio’s upcoming products, representing a new era in Campfire’s legacy of high-performance premium earphones.
