is there a buzzer of sorts that replicates the mosquito buzz ringtone on cell phones? Answered

this buzz, if u dont know, is a very high pitch/ frequency which can get kind of annoying u probably know what the next step is..

any small buzzer + 555 chip the really annoying buzzers (with unstable frequenc) have feedback coil in the speaker. but you can make a similar effect by using a second 555 (or 556 instead of 2 555s) diodes in parallel / series with speaker may add nasty distortion

thanks -- can u just say how to wire them up together...?
