Balanced armatures are one of the longest standing, foundational technologies in the world of high-fidelity IEMs. First designed for use in hearing aids, these highly compact transducers are well-suited for adaptation to earphones. The mechanics of balanced armatures lend themselves to incredible speed and accuracy, due to the small size and rapid movement of their diaphragm.

At Campfire, we apply a range of techniques to highlight these strengths and emphasize accuracy and technical performance, while conjuring greater emotional engagement and musical impact from the analytical nature of this technology.

Seen above, ten balanced armatures are combined with a range of Campfire's acoustic engineering techniques to create the astounding performance of Andromeda 10.

We utilize a range of armature sizes and mechanics, from large, woofer style armatures, to small 'tweeter,' high-frequency focused drivers. These are then combined with precision engineered tuning chambers and damping values to shape each drivers performance. Finally, driver-to-driver interaction is also carefully addressed to ensure smooth transition and crossover between different frequency bands.

Balanced armatures are a small transducer that consist of an armature suspended ('balanced') in the electric field of a magnet coil. Incoming electric signal manipulates the electric field which moves the armature. This movement is then transferred through to the driver's diaphragm which creates the air pressure waves that we perceive as sound.
