Further Information

Excuse my ignorance but what is the difference between a buzzer with a drive and one without? What does 'drive' mean? Thanks
Asked by: Phil Lawton
As you say there are two types of buzzer, with and without drive. A piezo element in its simplest form is without drive and needs to be driven with a square wave. This can be done through a microcontroller such as a PICAXE IC or through a timer chip such as the 555 timer in its astable mode. The benefit of the buzzers without drive is they are both cheaper and the frequency of the tone can be change, so can be used to play tunes. The buzzers with drive have additional circuitry which generates a fixed tone, in effect they are doing the job of providing the square wave and have the element all in one package. Because of the extra components inside the unit they are a little more money, but give you the simplicity of just being able to connect power to the device. The buzzer you are looking at is an electromech
anical buzzer. The way the drive works inside this buzzer, is that there is a coil which when powered pushes the part that moves the air forward, this section is also set up so that it disconnects power to the coil and then a spring returns it. This pulls the part that moves the air back in and reconnects the power to the coil. This then causes it to repeat the sequence, this happens about 400 times a second and results in a fairly low pitch frequency. The piezo buzzers with drive are a much higher frequency about 4Khz compared to the 400Hz of the electromechanical buzzer.
