I made Franken - Bluetooth speakers. Works better than I thought. One 3rd party ryobi battery is enough for a festival week. The second Bosh lawnmower battery adaptor works fine too.
Oh my, you’re who I want to talk to. I have been thinking about making a speaker probably for the opposite reason you did. I want it to be quiet. Quiet as a little mouse. Do you mind guiding me towards your method? Because I am just at the beginnings, but I was wondering if the hardware does the work, or if you get the fixings and then load the hardware up with something open-source. So if you’ve got the time, please let me know!
Ah, I was seeing it as some kind of project in wait and figured I could get some advice from someone who’s been there. I don’t actually have a speaker system of any sort currently. I just wanted to make one for when I did the dishes or take showers. But I really dislike bass so I figured putting together a little 3 watter or something small would be fun and interesting. I also didn’t realize you could just add a resistor to dampen sound but it makes a lot of sense. I haven’t done anything with electronics in a long time. But I figured no better time than today to pick something back up. Ty either way, and keep on keeping on =)
I’m not the person you replied to in the first place, I’m sure they have a lot more to say than my simple advice
The volume of a sound is its amplitude, which correlates to its kinetic energy. Kinetic energy in a sound comes from the electrical energy in the speaker. You can lower electrical energy with a resistor.
Ah, snikes - apologies. I was on the end of a long pain bender (doing pretty solid today) and my whole system wasn’t in one piece. I read up on it as soon as you said something and it made sense to me. Although I thought of use case between an actual speaker versus a bluetooth and between the two I said - well one would just charge slower and the other would just receive less power and sound fainter. But yeah, I don’t have an actual speaker system as a whole, in any entity. I just have a laptop, and a monitor with two little tweeters built in. And then my phone. I used to give a hoot about music very much so, and be perhaps not an audiophile, but an enjoyer of volume and levels. But now I just want to listen to something, with a little volume - that I can just turn on when bathing or doing the dishes. Because I realized many moons ago I used to have a boom-box that I’d jam out to in the kitchen which made the entire process more enjoyable as a whole.
A couple years ago I got an electric lawnmower super cheap. I only discovered earlier this summer the lawnmower and accompanying weed whacker were being discontinued, and if they break in ways I can’t fix, I’ll have a 60v, 5 amp battery to recycle play with.
It hasn’t occurred to me to reuse the battery for some other fun project. There will be shenanigans.

Also GJ on the frankenspeaker!
Just throw a resistor on it to make it quieter.

Thanks though, yet again!
What amp you use? Is it stereo?
Love it!
I still had a Tda7492p board laying around. That’s a stereo Bluetooth 4.0 board with 2x50W (8-25V).
