I broke my mirco use charging port for my speaker and i don’t have cash to fix it. Would is be possible to cut my phone charger and the connect those wires charger:Blue Red ^ ^ Speaker:Black Red

Are those wires (Black and Red) connected to the speaker itself? If it does, you snapped the wrong wires. Solder them back to the board. You could solder a connection but the speaker won’t be portable anymore (since the charger is soldered into the board of the speaker). Solder the Positive wire of the charger to the positive terminal (the place where the micro usb connector is attached) and negative to the negative terminal.
