Analog (red/white) speakers to laptop headphone jack

[Expectations]

Hi, first post. Hope it's in the right place.

I'm in need of new speakers for my laptop as the old ones have gone kaput. I have a pair or analogue (red&white,+/-) speakers sat in the cupboard. (Technics SB-F950) What is the name of the adapter I would need if I could use these in some way for my laptop? ... or any other 3.5mm jack for that matter.

I have something similar to this

plug it into the headphone jack and you have sound.

Actually, this is my model

It has a popup and also can be charged through a USB port.

Hey

That's not what mine are like. They are large hifi speakers with the bare red and black wire connection. I was wondering if there was a way of making them compatible with a laptop or computer.

You need an amplifier to power those speakers, plodr was offering a much cheaper alternative to that.
