PIEZO ALARMS
ENCASED EXTERNAL DRIVE (no internal circuitry)
The piezo alarms described on this
page have no “feedback” tab and are
particularly suited for the generation
of both single tones and the unusual
sound effects that are possible with
specifically designed driving circuits.
These sounds may include musical
melodies, insect sounds, etc.
All mechanical and electrical
components are designed to be
compatible with most standard
PC board assembly and wave
soldering techniques.
PKM Series
FEATURES
I Rugged construction

APPLICATIONS
I Musical toys
I Home appliances (microwave
ovens, refrigerators, etc.)
I Communications equipment
I Computer peripherals and office
equipment
I Instrumentation, etc.
