Martin,

I'm not aware of a module - but there are a lot I don't know about, 
anyway.  Just one note - it's the transducer which actually generates 
the sound; it's being fed with a DC voltage.  Connecting headphones to 
this will only give you a click in the headphones (and probably blow the 
board due to the low impedance of the headphones).

IOW, don't even THINK of doing it :)
