Specialty Transducer Speakers
Knowles sub-miniature speaker designs are based on balanced armature technology and are
utilized in a variety of high performance audio and communication products. Knowles balanced
armature speakers are available in several sizes and efficiencies, which can be finely tuned to
meet your specific performance requirements. They are designed for use in in-ear applications,
including earphones and communication earpieces, or be sub-assembled by Knowles for
premium consumer electronics accessories.

TWFK SERIES
The world’s smallest dual balanced armature speaker, the TWFK is designed for
pro-audio in-ear applications. Enables customized cross-over systems to achieve
target frequency response in a package size smaller than the ED Series.
WBFK SERIES
Same package size as FK Series, WBFK has extended high frequency response.
It is recommended as a high frequency component to be combined with low/
midrange speaker for music earphones.
High efficiency, stability and reliability
Customizable performance and port locations
Ideal for premium in-ear designs
