BJ SERIES
Omnidirectional, Noise Canceling 7.92 x 5.70 x 4.14 (mm)
Knowles’ Magnetic Microphones (BJ Series) are based on balanced armature technology and
are self-shielded against external magnetic fields. The microphones offer high efficiency,
stability, and reliability and are small in size. The diaphragm of the BJ Series responds to
pressure differential, giving high rejection of background noise. Both face and edge ports are
offered. In addition, there is a short distance between front and back ports resulting in
improved noise rejection up to higher frequencies.
BL SERIES
Knowles’ Piezo Ceramic Microphones (BL Series) are rugged, stable and versatile.
BL microphones are available in three different package sizes: standard, thin or 0.5"
cylindrical shell and cable assembly. Both communication and broadband frequency
response versions are offered. In addition, BL microphones have high vibration sensitivity
and may be used as accelerometers.
Note: All performance curves are typical
