How to disassemble Xiaomi Roidmi 2S

Hello.

I am thinking of tweaking Xiaomi Roidmi 2S a bit because it has rather low quality microphone build in. I'd like to solder a 3.5 jack socket and that way attach a small directional external mic.

But I don't know how to disassemble this device :)

Can anyone help?

A perfection would be to put it step by step on YT.

Hi,

I already dismantled Roidmi , its easy but you need strong nails :)

from the up side the USP cover, i inserted my nail between the USB cover and Roidmi body then carefully pull it out from one side, then you need to go around to pull the other side clip.

The problem that my Roidmi not working i couldn't manage to know what is the problem.

If you need pictures just let me know.

Regards,

Isn't the Xiaomi Roidmi 2S a bluetooth FM transmitter for your car? It doesn't have a mic? You sure you are talking about the same device?

I may be wrong, but I'm afraid you do not have a microphone. Should be at the top. Next to the usb socket. Do you have a small hole in the cover?

完成的

yes, you are right, it should be close to the front part and behind the holes, can you provide clear and zoom in picutre of what is around USB connector and at the back, also look care fully inside usb connector, show us the back of the cover you removed

完成的

I'm not sure whether you disamble Roidmi 2s.

As you can see on my link it's clearly visible microphone "hole".

On your photos&film I cannot see similar part...

Hello Michal,

It is Roidmi 2s. You are confused because the images you are looking at are of the internal parts. I have created 3 videos for you guys, showing its outer shell along with internal parts. These videos should give you a really good idea on how it is assembled and how to disassemble it.

In my experience, I do not think that you can disassemble it witout doing any harm to its outer shell. As you can see in the video I did manage to open it but there is quite a bit of damage to the front cover but I am ok with it because it does not affect its functionality in any way and I can stick it back with some super glue.

https://www.dropbox.com/sh/d63s2ju16l45c...

I have moved on from modifying the Roidme 2s and installed a music system in my car with performs way better. It was a mission as my car is a bit unique but I did it at last.

Good luck

Hi, if there is no pressure/humidity sensor in this device the microphone is located on the rear side of the front PCB, where the USB sockets are soldered (see IMG_3697.JPG). Maybe it is possible to desolder it, solder copper wires to the board and either connect a new microphone to it or the original one just to put it in a better position.

Cheers,

Helge.
