Flip your speaker upside down so the charging port side is faced upwards.
Place the end of a metal spudger in between the rubber bottom and the mesh case.
Work your way around the base of the speaker until the top separates from the case of the speaker.
This will take force.
Use the metal spudger carefully. Improper use may lead to injury.

Step 2

Pull the bottom end of the speaker off and place it aside.
Once the glued seal is broken you will be able to pull it off with your hands.

Use a metal spudger or another suitable opening tool to push the metal rods on both sides of the speaker until they extend past the end of the device.
When the rods are pushed out far enough, use pliers to pull them out the rest of the way.
Repeat for each metal rod on the speaker.

Step 6

Use a spudger to apply an upward force on the speaker plate.
Hold the speaker with one hand and use a spudger to pry the speaker off.
This will take some force.

Step 7

Squeeze the end of the connector to release it from the socket and remove the speaker cables from the motherboard.
If you have difficulty removing the speaker connector, take a look at the Recognizing and Disconnecting Cable Connectors guide for additional help.
