Piezoelectric Acoustic Generators
Oscillation Type Circuits
A Piezo Transducer with a feedback tab makes the circuit
oscillate without inductors and capacitors. The number of
components is reduced and it is possible to generate from a
sine wave to a trapezoidal wave.

NOTE: Wherever possible, the piezo devices should be
capacitive coupled to avoid permanent DC bias and possible
long term damage.

CBZ
It is easy to build this circuit by using CMOS inverters,
such as MC14049, and MC14069. The oscillation frequency
is in proportion to 1/R

INPUT
It is easy to do on-off oscillation by using a CMOS
NAND gate such as MC14011. When the input terminal is
high, the transducer works. When the input terminal is low, it
stops.
This is an example of a circuit that will generate various
sounds using one MC14069. The frequency determined by
R

to the transducer as V

Position 3:
interrupted sound
