Generation Of Sound With The Micropump mp6

Q Why do the micropumps mp6 generate a sound?

A The piezo actuators are driven by the electronic controller connected to the micropump. When the driving signal has fast amplitude changes and the set frequency is in the range of human perception, a sound can be heard. If a sinusoidal signal is used within low frequencies (e.g. up to 200 Hz), the lowest sound generation is reached. If a rectangular signal is used, the highest sound generation will be reached.
