3,5mm audio female pinout

[Yaion]

Hi, I have a bit of a project where I want to replace the speakers of an older model scala rider g9

So I thought while I'm at it I might as well do it the way I want it to be, so that I can actually remove the speakers and also using it with a headset for example, if I'm not on bike, but a car.

 

So I salvaged an audio jack from a really old laptop (hope it still works, but why wouldn't it unless the connections broke for some reason). Looking at pinouts online I saw mostly 5 pins, but I have a 7 pin , the mic jack was seperate so I don't think that's it. Also I only have 4 pins to work with on the scala rider itself, so my question is, how do I solder this on?

There aren't 7 pins , there's 3 or 4 pins, and the rest are grounded (connected to the ground pin) and there just for mechanical support, so that jack won't break or wiggle when you insert and pull out the audio cable.

 

The audio jack is normally  ===[ GROUND ] | [ LEFT ] | [ RIGHT ] ) so one pin is left channel, one is right channel and at least one is ground (common for both audio channels)

 

If you really want to be exact, you can get a male stereo jack, plug it into the female connector and then use a digital multimeter in continuity mode to figure out which pin is what.

It's not uncommon (especially in laptop connectors) that there be a completely isolated SPDT switch in there. That would account for 3 of the extra pins.

oh that makes it a lot easier, thank you

yea, while at work I was thinking to just take multimeter and see if there are pairs, and if those cut off if the jack is pulled, so I guess I'll just do that then

 

The plan is solid though, right? I can just solder the jack to the scala rider and use it as a connector/adapter?
