Self Drive Piezoelectric Transducer Operation:
Self-drive piezoelectric transducers do not have any DC circuitry included. They do have an
additional third terminal that is connected to a feed-back portion on the piezoelectric
transducer. By using a circuit which utilizes this feedback signal, the device will self-tune itself
to its optimum resonant frequency which guarantees maximum sound level from each part.
Typical Drive Circuits:
Notes:
These circuits are only initial suggestions. Values of the resistors may need to be
adjusted depending on the particular transducer model used.
Square-wave type signals result in more sound level than sine-wave type signals.
The more peak-to-peak voltage applied to the transducer, the louder the sound level.
However, applying more than 35 Vpp to the transducer is not recommended.
The final circuit should be tested over the entire operating temperature range and
voltage range of the equipment in which it is installed to verify adequate sound level will
be produced.
