Introduction: Wireless Speaker That Connect's in 0.0000000001 Seconds !

Picture of Wireless Speaker That Connect's in 0.0000000001 Seconds !

Feel Like Pairing Wireless Speakers Is really Time Consuming Process You Need To Make This Wireless Speakers That Connects In 0.000000000001 Seconds (Instantly) , Although It Doesn't Use Bluetooth or Wifi It Works For Every Smartphone, Tablet's etc...

To Build This System Just You Will Need a Audio Amplifier , I Used PAM 8403 its very cheap, transformer coil and speakers of your choise !

Let's Get Started !

Before I Recomend To Watch The Video You will know What i am tallking about !

Step 1: What's the Problem With Bluetooth ?

Picture of What's the Problem With Bluetooth ?


Pairing a wireless piece of headphones to smartphone takes a lot of time .

And Sometimes The Weird pitch shift , and latency is always big NO NO !

Also You Have To Recharge The Small Battery .....

Step 2: So How It Connects in 0.000000001 Seconds !

Picture of So How It Connects in 0.000000001 Seconds !

Every Digital Wireless system has Delay Due to various factors like medium,range,processing,etc...

But This Delay Can Be Reduced by use of analog transmission methods .

This System Works Similar To a Electrical Transformer , Supplied High Voltage is converted into magnetic field this magnetic flux get induced onto secondary coil and generates voltages in proportion to the coil turns ratio .

Here Coil Inside Smartphone Speaker Acts as Primary coil and Our External Coil Recives the Signals

This Signal is very small so we need an amplifier to be able to drive bigger speakers.

You Can Connect Ear buds or loudspeakers , and similarly can extract audio from any speaker source smartphone,tablet,tv, as long as it has speakers !

It Doesnt Require Pairing Since it's Analog and just does the job of Re- Amplification it connect's in 0.0000000001 Seconds !

Step 3: How to Make !

Picture of How to Make !

★☆★ Buy Parts from your online local store ★☆★

1. Winding Wire

2. PAM8403 Amplifier Chip

3. Speakers

1. You Will Need a Coil Which you can easily get from an old power-supplies transformers ,or just wound it yourself

2. To Boost The Small Audio Signal Amplifier is required ,I used class D PAM8403 ,But Any Amplifier Will Work Fine ,Even Your Home Theater Also ! (Just Make Sure Volume is Low !)

3. Connect Speakers at Output and Bridge Right and Left Channel Input and Connect The Coil ,Supply The Voltage And Its ready !

4. You May Need to put a capacitor in parallel with voltage source because ,for the higher amplitudes this amplifier will draw more current so to keep it running continuously add a 2200uf capacitor.

Step 4: Can You Get Superpowers With It ?

Picture of Can You Get Superpowers With It ?

Yeah !

if Some one challenged you to guess the music they're listening to , You can guess the music by just simply hold the coil over earphones and listen the music clearly !

There's Even More !!!

Listening to the electromagnetic waves is whole New World , You May never experienced this but might be familiar with interference created by calls with speakers ! yeah just try scanning different parts of your smartphone and you can able to listen what going on inside CPU , RAM, Network Chips etc...

in the pics he has a HUGE coil. You can make the coil with 100 Turns #30 AWG wound around the end of a pencil. Teeeny weeeny.. and it will work just as good.

RobotsMaking (author)JohnC4302017-02-05

Thanks for the info! How did you calculate it? Becaus I can than calculate my own coil :)

MinaN7 (author)2016-11-01

how can i wound the transformer by my self and can i connect it by 3.5mm aux jack ?

jimvandamme (author)MinaN72016-11-04

It's a lot easier to scrounge an old transformer and take it apart to get the windings. You can solder the two wires to an audio jack. It's mono, so use the two connections together, with the other wire soldered to the ground. Plug it into an audio amp.

MinaN7 (author)jimvandamme2016-11-14

this will help or not and which side I will connect it and how I disassemble it without hurting myself ?

jimvandamme (author)MinaN72016-11-14

That looks like it has interleaved laminations so you'd have to take it apart leaf by leaf. If it's varnished together that would be a lot of work. Find a transformer which has the E laminations that separate easily from the I laminations, and the bobbin with the windings just slips right off. Solder wires to the terminals of the finer windings and you're done.

Or, buy a small reel of magnet wire.

jimvandamme (author)2016-11-04

This is pretty clever. But...

I find it's just as quick to plug into the headphone jack to get full fidelity stereo, and you may have enough power to run passive speakers. If you have an amp, you'd get any amount of power you want.

Why did you post this in the arduino section? This has no relation with arduino.

i Post in Speakers section.

Sorry, maybe this was a problem with the app or internet connection. I visited the technology/arduino section but your instructable was in that list.

duegy (author)Kedar Nimbalkar2016-10-27

Kendar I really like your out of the box thinking. In our world of technology today, people forget or don't know of some of the earlier devices us older people used. what you have made is a coil pick-up. there was a device Radio Shack use to sell that was a small coil with a suction cup and a simple mic jack, you would suction it to your telephone handle near the speaker and you could record the conversation without the other person knowing. The part I like is that you found another use for the pick-up coil. being able to set your ipod or tablet down on something with the coil under it to be able to listen to higher quality sound from an amplifier with good speakers, to me that's just awesome, keep up the good work.And Kendar please ignore the negative comments people seem to have a need to put others down so they feel good about them self.

available commercially but probably waaay more expensive :D

pthree (author)pthree2016-10-26

I love his reaction and him trying to figure out how it works

Chitlange Sahas (author)2016-10-25


JohnC430 (author)2016-10-24

Guys!!! don't focus on the number of 000 he put there. he obviously just threw them in to emphasize that the "delay" would be minimal.

praju1 (author)2016-10-23

Good work Kedar... application of basic physics in real world.

However the only problem will be placing the phone near the coil which doesn't allow the flexibility of Bluetooth. Further, modern Bluetooth speakers uses advance authentication options which connects every-time you come in range. Interesting hack though...

venkess (author)2016-10-22

Wat abt connections.. can u pls give in detail abt connection and product availability. I need to make this so pls reply quickly..

KundanA2 (author)2016-10-21

@kedar, great work. this could be my first DIY :D
and yes comments main faltu ki ladai pe muje hasi aarahi. ! LOL

sheldonl1 (author)2016-10-18

So Good man! love the idea! mabe i will build it in an effort to improve its design (if at all possible) because im in an Electronics Engineering Technologies class.

AlDee (author)sheldonl12016-10-21

I think an improvement might be to add a second pickup coil and separate the inputs for stereo use, and maybe a band pass filter to eliminate noise.

I would love to see your improved design.

I havnt had the time nor the resources to do this. also, im just a first year engineering student. so it may be a while before I can do some testing.

Dear Kedar Nimbalkar,

A very nice Instructable. It is a great idea, and it definitely is nice not to have to pair speakers with a phone's bluetooth.

Thanks !

Dear Kedar Nimbalkar,

Your welcome.

The very best.

OMG you've reinvented the radio, it seems you're the Marconi of the 21st century. Wireless only worth it if the distance is significant, here it seems to be less than a few inches. Analog doesn't mean instantaneously and your 0.0000000001 seconds are really too optimistic, not to say that's not true. Formulas exist to calculate the propagation time in a magnetic coil, without talking about dephasing. This time introduces distortion and limits the bandwidth.

TechnicalJohn (author)rafununu2016-10-18

Jeez, backup for just a second.

I admit his title is a little bit "click-bait", HOWEVER people have been struggling with how to connect to docking stations for a looooong time. This actually creates a really neat solution to that dilemma, since you simply need to locate the speaker on your smartphone, put the coil near it, and you can pump the sound over your loud speakers!

Excellent job!

rafununu (author)TechnicalJohn2016-10-19

Sure, and you'll pump the 50Hz mains as well. You'll get a quality close to an original Gameboy ! I'm sure you'll get a better quality with an electret microphone !

RaymondR6 (author)rafununu2016-10-18

Marconi invented the wiremless transmission of noise (from a spark generator) and the first use was wireless telegraphy. The first tuned (frequency stable) wireless transmission for audio, which is what we call "radio" was invented by Nikola Tesla. Tesla even had to sue Marconi for the "radio" invention.

VictorM124 (author)RaymondR62016-10-18

Before Marconi was born the "wireless telegraph" worked. Use Google search "Mahlon Loomis". Loomis, a Washington, DC dentist, claimed to have transmitted signals in October 1866 between two Blue Ridge Mountain-tops 14 miles apart in Virginia, using kites as antennas, but without having identified the names of independent witnesses.

Loomis received U.S. Patent 129,971 for a wirelesstelegraph in 1872.

NathanKing (author)2016-10-18

Very nice! Keep up the great work :)

Thanks !

JohnS335 (author)2016-10-18

So someone else said it. This is just a radio, but with a baseband carrier so no real range. You will get a 60 Hz hum(50 for our European friends) that will drive you crazy. AM modulate a different low frequency carrier for each channel (keeping your power within FCC limits) and you should be able to get the same effect with better range and no hum.

AlDee (author)2016-10-18

Very Nice! I like the concept, and I see lots of potential other uses such recording audio from other sources where a speaker is used. I'm old school and a bit of a purist when it comes to listening to music. I prefer to listen to true stereo, hardwired through separate channels. (I feel there's too much of a trend these days to sacrifice quality for convenience.) With that said, I would put this up against any Mono channel blue tooth speaker design.

MattBothell (author)2016-10-18

Interesting idea!

maurice.arnott.9 (author)2016-10-18

Very clever thinking outside the box well done
