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 EMAT:

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.

3Caution must be taken when handling magnets around steel products.
