SPECIALTY TRANSDUCERS – Speakers
FK SERIES
– Balanced Armature Speaker 5.00 x 2.73 x 1.93 (mm)
The world’s smallest balanced-armature speaker, the FK Series is designed
for applications where size is the most important design concern.
114dB SPL maximum output
Two-terminal zero-bias configuration
Undamped, screen damped, and internally damped responses
Wide range of coil impedances
Sensitivity @ 1kHz

FH SERIES
– Balanced Armature Speaker 5.09 x 2.80 x 2.59 (mm)
The FH speaker represents an unprecedented combination of ultra-compact size and high SPL
output with efficiencies normally found only in much larger speakers. The FH speaker
line brings true high-gain, high-output performance to earphone designs.
Undamped, screen damped, internally damped, and Ferrofluid
damped responses
Various port locations, coil impedances, damping options,
termination configurations, and frequency responses available
Maximum SPL output of 123dB at resonance peak, 109dB
at midband (500Hz)*
