So my phone's speaker is dead and I thought of something
Is there a product out there that can be used in the way the picture below (or above) shows? A really small speaker that's in (or silighly bigger) the similar size of phone's built-in speaker.
They’re called mini aux speakers. The sound quality will be absolute crap and it will stick out like a giant goiter, but they’re pretty cheap and easy to find. They used to be used for mp3 players and walkmans that didn’t have a built in speaker.
Be cautious about carrying it in your pocket. Bending over and sitting down with it plugged into your phone can put stress on your aux port and kill it, leaving you worse off than when you started.
UPDATE: Well... 15 minutes after making this post the phone fell out of my pocket and slided 20 meters away. Screen died. I guess I won't be needing the speaker now.
But I believe this will be good opportunity to repair it. It was 4 years old. Thankfully one of my backup phones, an LG G4 still works. Which is 7 years old and has Android 6 on it. I'll go and look for a custom ROM I guess.
Found this from Google, can't make any guarantees about the quality and it seems a bit unwieldy for a phone unless you take it off to put it in a pocket.
If you're not planning on upgrading any time soon, a repair shop might be a good option. A smartwatch is a good workaround as they can give notifications and calls but they can be pricey.
Or you buy a replacement speaker and solder a 3.5mm audio jack on it, but I don't know if the headphone jack has enough power to power an external speaker
You just need a headphone attached to a trs plug. With most phones, if you don't use a trrs plug it'll keep the main phone mic active but route the earpiece audio to the headphones.
