Taranis Speaker Modification and Upgrade

Tagged: Taranis / FrSky / Modification /

The default speaker is weak and tinny sounding. You can add a new speaker for just a few dollars and some simple soldering.

Why you should do this mod

The Taranis is a great radio. They did a great job with almost everything about this radio. However they used a pretty poor sounding speaker. It has low volume and not much bass. Its ok for basic voice commands, but when it is louder or if you want to play music it is lacking.

This mod will put a much louder and better sounding speaker in there. The cost? $4 and a pill bottle.

Parts You Will Need

Instructions

1
Cut the top off the pill bottle

It need not be pretty, we'll trim it later. You just need to cut the top threaded part down and then remove the top from the rest of the bottle.

2
Remove the stock speaker

(Sorry, didn't get a photo of the stock speaker) We need a round section that fits the speaker, and a round section that fits the Taranis speaker mount. You'll need to open up your Taranis and remove the stock speaker to do this. The Taranis opens by removing a few screws in the back. Once open you can pull/pry the speaker out. It is glued in place. Then disconnect the plug that attaches it to the main board. You then have to remove the cable with a soldering iron.

We need a round section that fits the speaker, and a round section that fits the Taranis speaker mount. I used a rotory tool to cut and grind it down until the larger diameter fit the speaker and the smaller diameter fit the Taranis.

Make it thin
Make it thin

If it is too thin it won't fit inside the Taranis. So get it as thin as you can, while still fitting. This is what mine looked like. The edges don't need to be perfectly flat unless you are the type of person who seeks absolute perfection. If so, grace to you.

5
Glue the new speaker in place

Fit the two together and then hot glue them together. As you can see this is not as elegant looking a mod as the 3D printer approach, but hey, it works!

6
Solder the old connection in place
Solder the old connection in place

Solder the wires onto the speaker. But which way should it go? This is VERY important. If you do it the wrong way the speaker will be out of phase. That means it will move inward and not outward as it should. To determine correct polarity/phasing take a AA battery and tape two wires to the ends. Then touch the wires to the speaker power tabs. You have them on the right polarity when the speaker moves out. Then solder the red wire to where you had the positive wire, and brown to negative.

Install it in the Taranis

Now you just drop it into the Taranis, making sure the wire connection is at the 6 o'clock position. Hot glue it in place and then plug the cable in. Now enjoy a much better sounding Taranis.
