Sonos x ikea symfonisk move - DIY Hack




How it started

As Sonos has officially announced its mobile speaker Sonos Move today, many rumors about the hefty price tag have been confirmed: USD/EUR 399.- is not a bargain.

So I tried to make a cheaper version of it. Let’s say around 110.-. I took a Sonos Ikea Symfonisk, some already available Sonos hacks, a step-up booster and tools and stuff laying around at home.

I don’t have the skills to do things like that. But I’m not afraid of trying things… Right now I am having problems with auto power off of newer powerbanks. While booting the speaker needs to less power so they turn off. I have solved it by using older "stupid" powerbanks or by leaving the power cable in the speaker until I have started music - then I can pull the cord. Update<:/strong> I know have now ordered the Mi Power Bank 2S (Amazon affiliate link) it has a low power mode to charge small gadgets - it perfectly works now.

How I did it

1

Open the Symfonisk

To open the speaker I had a look at this guide by Ben Hobby before: Hacking the Sonos Ikea Symfonisk Into a High Quality Speaker Amp

2

Watch a video

This YouTube video by HackThatNow about adding a USB cable to a Sonos Play:1 helped me a lot.

Do the rest

See below.

Step by step

Image

Take the speaker apart

Just follow this guide.

Image

Solder the cables

Solder the two cables on to the circuit board. The red cable is the positive (+) contact. put the cables through the hole next to it. For the cables I used the other half of the USB cable where we will need the plug later.

Image

Drill a hole

Drill a hole into the case. I used a 4mm wood drill - but this depends on how thick your USB cable is.

Image

USB cable lenght

Use the right length of the USB cable so you can store it in the back when you don't use it.

Image

Fix the cable length

Fix the USB cable from the inside with a zip tie and cut off the end.

Image

Protoect the cables

Optional: As I had a yellow shrinking pipe laying around I used it to protect the cables coming out of the circuit board - without shrinking it.

Image

Solder the USB cable to the booster

Solder the USB cable to the booster. Red is positive (+) again. I use this Step-up Boost for less than EUR 5.- (Amazon affiliate link).

Set the output to 24 volts

Solder the two cables on to the circuit board. The red cable is the positive (+) contact. put the cables through the hole next to it. For the cables I used the other half of the USB cable where we will need the plug later. I use this EUR 12.- digital multimeter. (Amazon affiliate link)

Image

Connect to circuit board

Solder the Step-up Boost on to the cables running to the circuit board.

Image

Use lot's of hot glue

Use a hot glue gun (Amazon affiliate link) to fix the booster in the case. I also used some glue to fix the antenna cables to the board again.

Image

Reassemble the speaker

Image

Connect power bank

Connect your power bank and fix it with velcro on the back. Sorry, had only white one. Next time I will use this (Amazon affiliate link).
