Balanced armature technology

Knowles' balanced armature technology drives all modern hearing aids and the choice for today’s highly personal, portable, in-ear listening experience.

This technology enables the design of compact components with high output power and can be widely adapted and finely tuned to meet the performance demands of specific receiver and speaker applications.

For hearing aids, Knowles offers individually crafted balanced armature receivers and speakers featuring proprietary enhancements such as Pantograph™ higher audio output, Ferrofluid™ damping, D-Amp™ power management, and Vibration Isolation™.

For mobile electronic devices, our balanced armature technology offers you the capacity to create customized audio performance that is unique to your product or brand. A portable music player, smartphone, or earphones can be given its own “sound” by designing precise audio characteristics into the product.
