The audible buzzer alarms have always been a great help in alarming facilities. A buzzer is generally a warning sound. Their typical usage is for identification signals and alarms. The smaller level alarms serve in home-level requirements whereas the higher level alarms serve for industrial level applications. Out of various types of buzzer alarms available in the market, the piezoelectric buzzers have become the most preferable ones amongst others.
The piezoelectric buzzers use the high-quality piezoelectric elements for generating loud sound volumes at wide frequency ranges. The various attributes of this type of buzzers are:
