As shown in the figure, the multitone buzzer is composed of a six inverse buffer converter CD4049.It can produce a lot of tones if it is adjusted. In this circuit, four gates of CD4049 form two groups of multivibrator respectively. The buzzer will produce sound after being driven by output of the logic control gate after buffering and transforming.
