Sony trv-118 blown speaker?

[gopher]

my friend gave me a ccd trv118 camera to fix the internal speaker, there was no sound.
i took it apart and determined that the speaker is blown
its very small 16mm ( 1/2 inch ) in diamater with a wire 5 cm long
the speaker cone is plastic
any ideas what i could replace this with? where i could get one? Im wonndering if they put the same speaker in all the cameras?
