can you guys please help me build a simple transistor audio amp like the following

or this
http://www.next.gr/circuits/buzzer-interfacing-with-pic16f877a-slicker-l48286.html
i try the following circuit but there is no output.
my only available materials are
bc 548b transistor
4 ohm 0.5w speaker or d24mm Piezo Transducer
i know i need to consult the datasheet to solve for the base collector emitter parameters but i dont know how.

my source is a frequency generator using 555timer ic with potentiometer varying the frequency
pin output from ic is around 20 -25ma max
my desired output is something like this
hoping someone can teach me how to make one and how to compute one
many thanks in advance.
