Where do Ifind this part...

[john Gram]

I'm repairing a Sony SRS-x55 Bluetooth portable speaker.
A piece has fallen out where the AC power adaptor fits into . I'm missing the female part. I've attached a photo of the needed part that's missing from the yellow piece.
Is it proprietary to Sony? Sony is zero help with this.
Thanks for any info.

This is rather probably a standard dc power jack. You find them in many stores, e.g. here. The important measure is the diameter of the plug.
If you don't find a matching port for PCB mounting, you can use one which is mounted into the housing, fixed by a nut, and use wires to connect with the PCB. In that case, observe polarity!

Thanks for the info Harald. I'm curious to try the nut idea for learning purposes.
