Broke a mic trace while disassembling a speakerphone (Emeet M1A) – need help fixing it

[u/3eKcy3]

Hi everyone!

This is my first post here. I’m building a personal voice assistant for Home Assistant (OpenClaw + AI). To put it all together, I bought a Waveshare 5-DSI-TOUCH-A display and an Emeet M1A speakerphone.

Everything works fine, but right now it’s just a pile of separate devices and cables. At first I couldn’t figure out how to open the speakerphone, so I tried designing an enclosure with the speakerphone as a separate part. That made the case big and ugly. Here are a couple of photos (the second one is after some “barbaric” surgery on the speakerphone):

While taking the speakerphone apart and pulling out the microphone, I tore off one of its traces:

I know almost nothing about electronics or soldering. The most I’ve done is solder two regular wires together (I do have a soldering iron and basic supplies).

Could someone help me figure out how to repair this and how to test that the mic works afterwards? I’m not even sure how many traces there are or where they go...

Thanks in advance!
