From Reddit https://www.reddit.com/r/techsupport/comments/g5aynj/can_someone_help_me_identify_the_specifications/ I tried to get specifications of a speaker. This one here is specifically for ASUS ROG GL752VW, a gaming laptop.
What was found out is that it is possibly a passive speaker, so the speakers don't have any power in it, analogue audio, apperantly. Unsure if it gets sent in digital or analogue.
Here are some images of the speaker from the Google search: https://i.stack.imgur.com/6yTNl.jpg
and here is a picture of the, that was found from the Reddit post and the image is from here https://www.ebay.com/itm/ASUS-ROG-GL752V-Internal-Speaker-MT2920b/114108584582?hash=item1a9166d286:g:mQoAAOSwfiNeQgK3
From the image of the cable you can see that is uses 2x black, 1x red and 1x white wiring colors. This cable is from the speaker and later gets connected somewhere on the mainboard.
What I could also find out is that the speaker might was made from a company called VECO if, I compare the logo on the casing http://www.veco.com.cn/.
Now my question is, what do each of these colors here mean? And how do the speakers work, do they need power or not? And is it possible to determine what their specifications are, as example "2W x Stereo" or something like that.
