Passive buzzer have not internal drive circuit inside, We used to
name them as acoustic. Passive work buzzer square wave signal.
Passive buzzer can't make a sound by direct current.
The disadvantages of Magnetic Transducer:
1. Low transduction efficiency. EMAT transducers typically produce
raw signal of lower power than piezoelectric transducers. As a
result, more sophisticated signal processing techniques are needed
to isolate signal from noise.
2.Size constraints. Although there are EMAT transducers as small as
a penny, commonly used transducers are large in size. Low-profile
EMAT problems are still under research and development. Due to the
size constraints, EMAT phased array is also difficult to be made
from very small elements.

can be anything which converts one form of energy to another. Piezoelectric material
is one kind of transducers. We squeeze this material or we apply
force or pressure on this material it converts it into electric
voltage and this voltage is function of the force or pressure
applied to it. The material which behaves in such a way is also
known as piezoelectric sensor
.The electric voltage produced by piezoelectric transducer
can be easily measured by voltage measuring instruments, which can
be used to measure stresses or forces. The physical quantity like
mechanical stress or force cannot be measured directly. Therefore,
piezoelectric transducer can be used.
