Cellular phone and speakers?

Hi Chaps,
I have a pair of unused Vienna Acoustics bookshelf speakers in a small library and would like to know if it is possible to connect them directly to an iphone 8 just to listen to background music. Room is full of books, papers, magazines, etc, there is not even space for a small integrated/CD player combo.

I know nothing about cell phones and digital audio, my main system is analog.

Thanks much.

Cheers,
