Electret Microphones
& Silicon Microphones
As a leading developer of acoustic
components for commercial and industrial applications we offer a wide
range of microphones manufactured using state of the art technology. Each
unit features an optimum combination of performance, reliability and clarity
giving the flexibility to meet specific customer applications.
We are also pleased to offer custom
developed microphone solutions where we are happy to work with your engineers
to provide the accuracy and definition that is required to meet your individual
requirements.
Microphones are available in SMD
surface mount, with or without pins or alternatively with a leadwire which
can be to your required length. Leadwires can also be fitted with a specific
connector and with other components in line or with rubber holders.
Capacitors can also be built into
the microphone thereby reducing costs in assembly and assisting with noise
reduction.

Unit of Sensitivity
-
We
use "Pascal (Pa)" as the unit of sensitivity in all of our
specifications instead of "u bar" "Pascal" is
per the recommendation of I.E.C. (International Electrotechnical Commission)
and is currently the most commonly accepted. In some intances "ubar"
is still used.
-
To
convert "ubar" to "Pascal", simply add 20dB. Be
sure you are adding a positive number to a negative number
e.g. 62dB(0dB=1V/u bar)= -42(0dB=1V/pa)
If you are interested in buzzers,
speakers or vibrator motors select below to go to the relevant section
