Have you ever notice how the acceleration, pressure, strain or temperature can be converted into the electric charge? It can only be possible with the help of piezoelectric transducer as you can find it in most of the devices like microphone or earphones.
How does it work?
If we talk about its working then the very first basic thing you need to know is that it converts one form of energy into the other. It works like a squeeze mechanism as the force or pressure is applied the transducer get squeezed by which it converts the energy into voltage.
It is one of the modern or we can say advance technology which now can be found in many things like the earphones, automobiles, medical diagnostics and much more. The pressure does not need to be much higher in order to get it work. Low pressure will work definitely without any issues at all.
Everything about piezo buzzer
A buzzer is a part of the piezo transducer as buzzer produces sound if any pressure is applied. The working is same as the above like the applied force or energy is converted into the voltage and thus that voltage result in the output.
There is a ring or we can say beep sound is commonly used in this mechanism by which you will get to know if any pressure is applied on the ring. There is no need of external force as button is the only thing you need to press it and the work will be done.
In this way the piezoelectric transducer works as there is nothing more you need to do about it.
