Knowles Corporation (NYSE: KN), a provider of advanced micro-acoustic microphones and speakers, audio solutions, high-performance capacitors, and RF products, announced that it is celebrating 75 years of “innovation and industry firsts that have redefined the audio experience for generations.”

Knowles has been involved in many historical moments including the first Apollo mission in 1969, where Neil Armstrong spoke into a Knowles microphone, to the Mars 2020 Perseverance rover, and from the first hearing aids developed in 1954, to today’s advanced hearable technologies.

Since 1946, Knowles has innovated precision hearing assistance and speech intelligibility in the hearing health industry with microphones, speakers, and hearing aid components and accessories, according to the company. Knowles introduced balanced armature receivers to the hearing aid market “to effectively improve sound quality with heightened fidelity, realism, and detail for miniature, invisible hearing aids,” according to the announcement. In the 1980s, Knowles began evolving balanced armatures to deliver “premium sound quality to the music business.”

Pioneering the MEMS microphone technology under the SiSonic brand in early 2000s, Knowles created “a new de facto standard for microphones addressing several significant challenges afflicting prior technologies.”

“The modern world depends on the technology that Knowles delivers,” said Jeffrey Niew, President and CEO of Knowles. “One could easily interact with over 20 Knowles components inside the devices that they use every day. Your cell phone, laptop, tablet, smart watch, headphones, smart speaker, car, and anything that has voice control all rely on Knowles technology. As the inventor of MEMS microphones and balanced armature receivers, Knowles has developed technology competencies and a high level of quality that has been forged through many years of leadership in the hearing health industry. Our experience, expertise, operational scale, and global support create an unmatched edge. We’re uniquely positioned to bring voice integration and audio innovation mainstream.” 

The Knowles Precision Devices division is responsible for supplying components such as capacitors, microwave, and RF solutions to fast-growing markets that require high performance for mission-critical systems that cannot fail, such as military, medical, electric vehicle, and 5G. From 8,000 feet below the earth’s surface to orbiting 254 miles above us on the International Space Station, Knowles capacitors, microwave, and RF components are “technologically advanced to meet the demand.”

“What sets Knowles apart is our history of collaborating with customers to solve difficult problems. MEMS microphones and balanced armatures were solutions to big problems in the industry,” said Niew. “Today, our teams thrive on solving for hard-to-meet performance requirements and complex technical challenges with solutions that make it easier for our customers to bring new technology innovations to market to keep pace with the fast-evolving way that we are working, living, and communicating. I am grateful for the innovation, commitment, and incredible effort that our employees bring to work every day, all of which makes Knowles the reliable and trusted partner it is today. Together, we look forward to building the next wave of industry firsts for years to come.”
