Xperia Arc S distorted sound – earpiece replacement

After a year of active usage of my SE Xperia Arc S, I have faced a problem when sound, coming from a small front speaker became distorted. All voices had a buzzing effect as well.
Fortunately you can easily find an earpiece replacement for 2-3$ on ebay.
I have even bought a set with tools, to disassemble my phone. (Search for “Replacement Ear Earpiece Speaker+Tool for Sony Ericsson X12 Xperia Arc S” )

The replacement procedure in pretty simple, you just have to be careful and have a bit of patience. No soldering is required for the replacement.

Here is a procedure to replace the front speaker:

1. Detach the back cover, remove Battery, SIM and memory cards.

2. Unscrew 4 torx (star) shaped and 2 cross shaped bolts. Open HDMi cover.

3. Separate the covering panel. This can be easily done using your nail, or special tool starting from one of the phone corners.
Move the tool in clockwise direction and make a small gap between the screen and silver panel on the side of the phone.
Then increase the gap gradually until the panel comes off. Be gentle doing this as the side frame is pretty thin .

7. Put new earpiece in, press it down the socket, so it is firmly in place. Place the small covering plate back, make sure it is locked on the left side as it was before.
Position the camera back on it’s place, you may hear it clicks when locked.

8. Put the covering silver panel back on the base on the phone, as before – push it firmly down, so there is no gap left, do it gradually – moving clockwise around the borders.

9. Insert memory, SIM and Battery back. Turn on the phone and test the earpiece. Congratulations!

  1. Thanks for good instructions! I didn’t have to glue the speaker to get good sound. I also noticed that at step 4, I only managed to tilt the camera 10-20 degrees to the left, and that was enough to open the contact plate.
