I did this too from diy perks and it is soooo nice to have stereo wireless speakers. Its literally something Ive wanted since i was a kid

[backdemoletor]

always amazing elecronoobs.. so far this is the best arduino diy channel i have seen.. good job (we are still waiting for the new smartwatch version :D )

Cool project. Keep it up. And love your new website🙂

You can solve the Noise Interference when using same battery with a ground loop isolator like B0505S-1W DC-DC. and also i would suggest you add a switch between the earbuds and amplifier to interrupt the annoying voice prompt at startup.

Best video of DIY TWS Speaker I have found so far. Thanks a lot. From Bangladesh.

Really cool idea, I think I will make one for myself. Some problems/improvements I see for others:
1) Your midrange is not mechanically isolated from the woofer. Might want make an internal enclosure inside. Could also damage them otherwise. Plus you could be losing some bass right now.
2) I could be wrong but I think you might lose some response due to polarize caps. You could put two eletroytic caps in series in + - - + configuration, or invest in more expensive non-polarized caps.
3) Resistor-divider network from main battery for zero noise power to the earbuds since they take very little power anyway (less than led).
4) Case could be reinforced with which is an amazing acoustic barrier, and can make very deep base possible if case is designed for some good resonance frequency.
5) Could add a small piezo or coil based tweeter for proper high frequencies, or maybe a smaller midrange which usually can perform better at higher frequencies.

Great project👍, a lot of people are interested in these types of projects.

Sir what is the value of resistor and Capacitor of low or high pass filter

[siv_valentin]

11:22 Or maybe u can connect negative from earbuds to amplifier negative power input and positive from earbuds to positive from first li-ion battery from the bms.
And to remove push buttons, u can program 2 attiny85 / attiny 13a to send a pulse to optocouplers(which is connected instead push switches), but just for 500ms at the power on.
I hope that's helpful! :)
BTW: This is a great and interesting project.

This channel is gonna make me a genius.

[ajeethsuryash]

Every video of yours is worth watching...

[anonuser]

The best. Yes it’s compact but you can make it more fine and smaller.

[dominik]

Could You share which IC was in this earphones? Did they had implemented some DSP which makes sound to fit more to small earphones?

[shadowhunterxxx]

You can use isolated buck converter instead of using tou seprated batteries.and is it produse nice sound without tweeter?and is it possible to use 15 wat driver connected to 30 wat amplifier?

[daveslater]

Brilliant presentation my friend, clear, precise and very enjoyable. I loved the banana for the visible scale representation by the way.😂

Oh the Time travel box, let's meet up in 3045 and I'll get you a coffee made freshly from my replicator. 😂

[MikeZ]

What about volume? Do you have to control both speakers independently?

[maskeddagyt]

hi can you explain the resistors used in the crossovers because i can't find the 1 ohm and 5 ohm resistors mentioned in your website, if you can give me the link for individual resistor rather than the whole set it would be helpful thanks

How do you charge the forth cell that is powering the airbud? I know that 18650 would last a few weeks of playing but still? Is there a 5v charging module after a step down? There are 3sBMS charges with 5v inputs available. I wonder if I connect that in series with a dedicated charger for a single cell, would that also create a ground loop like it did when you powered the earbud and the amp from the 4s pack? maybe i'll add a switch or install two separate usb-c charging ports. I saw many videos where the get away with a single battery for both bluetooth and the amp using some 4 pin module.

[erlangenemutya]

What is the value of the resistors that are being used for low pass filter and high pass filter.and off course the capacitor as well?

[robertfournier]

I did the same with less parts and better speakers at 50 watts at 4 ohms. Only now thanks that we think the same I also thought of Bluetooth headset as the source and separate amplifier. At 4.5 volts and yes direct to the input on the amplifier. The amplifier is 12 volt model with a micro class d chip. Cost was less than one hundred dollars. And I put two high quality crossovers that make the sound very good.
