How to make a bluetooth speaker?

Question

Bluetooth

I have simple speakers, is there a thing so that I can connect it to a speaker and via bluetooth I can play songs from my phone. I found an option on the net with soldering the module, but are there any ready-made options?

Answer 2

Yes, there was such a stray in Eldorado, it cost about 600 rubles. Black, round, flat, like Defender.
And so, probably, you can just buy bluetooth headphones with an output for the speaker, maybe there are such. Budget bluetooth on the Market Defender, Ritmix, but whether they can broadcast a signal to the speakers is a question :)

True, it works via Wi-Fi and it still needs software on the phone. You can search on "chromecast" on Ali, there are a lot of clones at a ridiculous price. But the issue with the software is open. And yes, if you decide to take an audio chromecast, hurry up - it seems to have been discontinued.
In general, exactly what you need is called a bluetooth transmitter. On the same Yandex, there are a million options: https://market.yandex.ru/search?text=bluetooth%20t...
Well, or look at Ali for a similar phrase, there are even more of them.
I just warn you right away, in terms of sound quality, all these options are complete garbage. If you want good sound, get a chromecast.
