Specialty Transducer Microphones
The Specialty Transducer (ST) product line consists of miniature microphones, speakers, and
assemblies. Hundreds of design possibilities can be applied to your product challenge with our
high-performance microphone designs. Ideal for new product ideas that require premium audio
and very small form factors, solutions include noise canceling, omni-directional and unidirectional
performance. Other variables include size, shape, amplification, sensitivity, low noise, and resistance
to vibration and mechanical shock.
ST components and assemblies are unique in fit, form and function. Our products are designed
into high value applications in markets such as the following:
•
•
•
FG SERIES
Omnidirectional 2.565 DIA x 2.565 (mm)
The FG Series microphone is the world’s smallest electret condenser microphone.
Its cylindrical shape and compact size facilitate compact designs. The FG can
also be used in directional applications as a matched omni-directional pair.
EM SERIES
Omnidirectional 3.63 x 3.63 x 2.28 (mm)
The EM is a popular, alternative omni-directional microphone. The EM can also
be used in directional applications as a matched omni-directional pair.
Note: All performance curves are typical
Communications – headsets, handsets, earpieces, telephony, voice recognition, emergency services, military, surveillance
Pro audio – in-ear speakers, lapel microphones, boom microphones
Medical and more – sensors, audiometers, medical implants
