alarm circuit for alarm clock

[skinnie339]

Hi there,
I'm builidng a basic ttl alarm clcok. I have all the major stuff built, clock counter etc. but I am stuck with implementing the alarm.
I have a circuit which uses a comparator to compare the clock output with the alarm time set by DIP switches, but my problem is with the actual alarm buzzer part. could anybody suggest a circuit which takes the high output from the comparator circuit to activate a buzzer circuit.
Any help would be appreciated.
Thanks.

Probably just a resistor and transistor. But, post your schematic...it reduces the guessing.
