The advantage to using an earpiece from a crystal radio is that they are very high impedance. This means the pager won't know it is connected to the speaker wires. If it is too loud, a little cotton pushed down the hole of the earpiece should do the trick. As I kid I used these to make crystal radios and voice powered communication systems
