With the back cover removed from your tablet locate the speaker and the speaker wires shown in the red box.

步骤 5

Since the speaker is magnetically held to the screen of the tablet cutting the old wires will remove the old speaker.
Use caution when cutting the wires, you want to cut the wires as close to the motherboard as possible without harming the motherboard.

步骤 6

Locate the positive and negative terminals of the speaker.
To attach the new speaker you must solder the new wires to the terminals on the motherboard. To do this hold the wire on the old solder, using a small amount of solder melt the solder and wires to the old connection points.
Soldering irons are very hot and can cause serious injury. If you do not know how to use a soldering iron please seek help from someone who is experienced.
