ABSTRACT:
In applications where mechanical vibrations should not cause a microphone to produce an output signal, opposing and series connected PZT elements (A and B) are used to cancel mechanical shock or vibration that might cause an output voltage or signal. Acoustic waves cause the PZT elements to deflect in opposite directions which when the sensors (A and B) are electrically in series produce a measurable output.
