Speaker/door question?

[Airdynamic]

Hey all....noob here with a B5 RS4 in New Zealand. I was changing the front Bose speakers as they had bad coils and I noticed this thing in the drivers door only. It looks like another speaker but smaller and "weird". Do you know what it it?

Thanks
Air

I have a customer with the same thing. I'm pretty sure it's a mobile phone speaker of some description.

Ah ok, thanks. That actually makes a lot of sense. I will have to see if I can utilize it in any way
