ok this is more useful let me see those numbers...
well first if you insist on using thattransformer, then solder it back on that board, and use that circuit to power your buzz box, and cut the speaker off if you dont like the music when you have to tase someone.
you arnt a terrorist or a criminal are you ? i dont want to put weapons in the wrong hands.
i think you need to give us a schematic of that board too.
EDIT: C-D appears to be by itself, a primary or afeedback i cant tell. also A-B-E i cant isolate these pinsfunctions, based on what youve given.
thanks for the reply. of course I am of course not a terrorist, even not thinking to use it on humans, just a mechanical engineer I nowadays realized that I had choosed wrong division at univercity. I was supposed to study about electric engineering. This electric stuff is now just a hobby for me. But I am trying my best to learn about it.
anyway, I will try to draw a schematic of circuit for your referance.What else do you want me to provide about the circuit?
PS: I had tried the transformer with 12V AC @ 50hz but I could not get voltage over 12V from any pins.

Solder the transformer back onto that little board, and cut the speaker off. Driving the transformer by itself is not as simple as connecting a power source, you need to pulse it at a couple hundred Khz.
a couple hundred Khz ?? but why? as far as I know, thoose the regular 220VAC-12VDC transformers can work with 50hz. I am confused :S

From the pictures it's easy to obtain the schematic. The power line voltage is passed trough a series capacitor and rectified. The rectified voltage powers a single transistor oscillator that uses the two coils AB and CD. The secondary coil is connected to the "B" pin. The two switches are power on/off and sound on/off. You can use the circuit exactly as it is, but it needs to be powered by the power line. It needs a quite high input high voltage (>100 V) to operate. It would be difficult to operate this circuit from a battery unmodified because of this. If you don't want the sound, just don't turn it on, or remove the small board, the blue switch, and the associated components.
