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.
What’s the difference between piezo and magnetic?
A piezo buzzer generates sound because of the piezoelectric effect
from the piezoelectric ceramic which drives the metallic diaphragm
A magnetic buzzer is based on the electromagnetic principle, the
metal diaphragm is pulled when input the power, and spring back
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.
