Now, on to removing the Speaker Chamber. The Speaker Chamber has a backside MEMS Microphone used for Noise Cancelation and Speaker Sound detection

Another nice find here, was that the Speaker Chamber MEMS Microphone flex PCB was connected to the Main PCB via a low force latching connector. Lifting the connector latch allowed the MEMS Microphone PCB to come free

This flex PCB also host the Battery wire solder connections for the system
