Morning, 

I got sent the following link from BBC bitesize science .

How to make a loudspeaker .

https://www.bbc.co.uk/bitesize/topics/zw982hv/articles/zg8rxfr

What do you know , it works pretty well.   Quite surprising given the amount of vibration the coil must give and voltage being applied from a small headphone socket .

Might be of use to any educators out there.
