Differences Between SMD Magnetic Buzzer and SMD Piezo Buzzer

SMD Magnetic Buzzer

Differences:  1.Current consumption is higher than SMD piezo buzzer(Common operating current                              should be within 100mA).However, its current consumption is still lower than speaker.

                    2.Voltage value of the product must correspond to the input voltage .And 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.)

 

SMD Piezo Buzzer

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.)
