SMD Piezo Buzzer
Advantages: 1.Current consumption is very small.In general,it just need 2mA current when operating at 3V.
2.It can be used at any voltage between 3-20V.
Differences: 1.The volume is bigger than SMD magnetic buzzer.Its sound is lower than SMD magnetic buzzer at same voltage .
2.The external input square wave frequency must be same with the operating frequency of the product.(Except that customers need the function that it can make different tones.)
