Hugh Knowles invented the micro balanced armature driver, and the company he founded has pioneered balanced armature innovation ever since. The world’s largest global producer, Knowles is the leader in balanced armature design and manufacturing with over 50 years of experience. Each Knowles balanced armature driver is individually adjusted and tested at the factory for consistent high performance.

 
Achieving true premium sound in earphones and advanced hearables requires close coordination of driver and earpiece design, especially with multiple-driver and hybrid systems. For this reason, many Knowles customers are using balanced armature drivers custom-tuned to match their particular ID, along with a properly designed acoustic path in the earphone. Knowles engineers combine balanced armature and dynamic driver expertise with deep acoustic knowledge to collaborate with earphone designers on achieving optimum performance.
