Model number: A3936
This is a step by step teardown of the Anker Soundcore Space A40 earbuds and their case with pictures. Both of them were defective and unusable prion to being disassembled.
This specific device has model number A3936.
After removing the back cover, the wireless charging coil is visible along with 4 screws.
Removing those 4 screws and lifting out the wireless coil's bracket reveals the main pcb. The magnets that attract and keep the earbuds in place are also visible.
Here is a picture with all ICs clearly visible. The main IC is the SS881Q microcontroller from Sinhmicro.
This is the back side of the main pcb.
This is the charging case's battery. A 13450 size battery with a nominal voltage of 3.72V and a capacity of 800mAh or 2.967Wh.
The earbuds were defective prior to being disassembled. I only opened the right one.
The earbud is held together with clips all around the casing.
Removing the outer piece of plastic casing reveals the top of the earbud's pcb.
There are 2 ribbon cables to be disconnected. The top one is connected to the battery and the bottom one to the speaker and charging pads. The pogo pins connect to the touch sensor located on the outer plastic casing.
This is the back side of the earbud's pcb.
Here is a picture with the main IC clearly visible. It is a WQ7033AX Bluetooth audio SoC from WUQI Microelectronics.
This is what is under the main pcb, the battery with its mounting bracket.
This is the back side of the battery's mounting bracket. The square gold pad at the bottom makes contact with the back side of the speaker.
This is the earbud's battery. It has a nominal voltage of 3.85V and a capacity of 53mAh or 0.204Wh.
This is what remains after removing the battery. On the bottom is the speaker, above it is the magnet that holds the earbud in its case and at the top the 2 pads that make contact with the pogo pins of the charging case.
