What is the input for on my speakers?

[Yolyx]

Hi
First off, I do not know anything about speakers. But recently I bought a pair of PC speakers, the Logitech z333 2.1 speakers. On the back there is an input and an output.

The output is where I connect my speakers to my pc, but what is the input for?
What do the colours represent (red and white)?
Can I connect my phone through the input?
In that case, which cables should I get?

Thanks in advance

Again...Page 5 in the user manual I linked in your last thread.

The inputs are for...wait for it....where the signal comes from whatever device you are using.
Like a DVD player. Or an 80's boombox. Or maybe your PC.

input, the red and white are the audio source, PC, MP3 player, the sound you want the speaker to speak.
output is the left and right speaker

you may need to get a 1/8 to RCA cable like so

not an endorsement just the first example I could find. shop around

From Page 5:

4.
A. If you have a 3.5mm outlet on your device:
- Insert the 3.5mm plug from the subwoofer into the audio jack on your device
(computer, tablet, smartphone, etc)
B. If you have on RCA outlet on your device:
- Insert the RCA jack on the subwoofer (the RCA cable is not included in the box
and must be purchased separately)
- Insert the other end of the RCA cable into the RCA outlet on your device
(TV, Gaming Console, etc)
