I've taken out a piezo buzzer from my alarm clock.But when I connect it to a 1.5V battery source ,it doesn't work.It produces very faint sound but it doesn't beep the way it used to in the alarm clock.
Then why can't you speak with proper English spelling like grown ups?
Many of us adults don't bother to read gibberish posted by kids who can't spell properly.

Seriously, that is one major peeve of mine. I get so damn tired of looking at that crap and like you, find myself ignoring post that are loaded with it. My kids no longer entertain the thought of emailing me with that crap and God help them if I ever see it in my grandchildren. Maybe as I get older my patience and tolerance for stupid is just diminishing, hell I don't know.
Yes, proper English is very important on this forum. I often have difficulty reading "texting speech" myself.
Anyway, to get back on topic, as I mentioned to you before, simply connecting the piezo to a battery and expecting a beep is like connecting a radio speaker to a battery and expecting it to make music. It just doesn't happen--It needs the additional circuitry inside the radio, or in your case, the alarm clock. To just get a basic beep, I would suggest you use a couple of 555 timer chips--one to set the correct tone of each individual beep, and the other to pulse that tone at the correct frequency to make the separate beeps. That way you would get the "BEEP-BEEP-BEEP" sound like you would from your alarm clock. This is probably the easiest way to do what you are trying to do.
