Founded in 1946, Knowles Corporation operates through two primary business segments: Precision Devices and MedTech & Specialty Audio. The Precision Devices segment focuses on the custom design and delivery of high-performance capacitors and radio frequency (RF) filtering solutions for defense, aerospace, and industrial applications. The MedTech & Specialty Audio segment specializes in balanced armature speakers and advanced microphones, holding a dominant market share in components for the hearing health industry. Following the late 2024 divestiture of its Consumer MEMS Microphones division, the company has concentrated its portfolio on higher-margin, mission-critical industrial and medical technologies. Knowles maintains a global footprint with significant manufacturing operations in North America and Asia, including facilities in the Philippines and Malaysia.
