Remove the back cover of the tablet by inserting a nylon or metal spudger in the small hole between the screen and rear cover near the volume button. Slide the tool along the edge of the tablet to release the internal clasps.
You should have to apply a good amount of force, but pry carefully in order to avoid damaging the clasps or the internals.
Remove the red and black connector cable linking the speakers to the motherboard with tweezers by pulling the connector to the left with a light degree of force.
To properly remove the speakers from the casing, push gently left until it shifts, then pull directly up.
Remove the 5 ribbon cables. use the tip of the spudger to flip up the retaining flap, making sure to lift on the hinge and not the connector itself, then remove the cable from the connector.
The flaps and connectors vary in color.
Once the hinge has been lifted, the ribbon cable should take no force to remove.
