Speaker = Generator (version 2015) 

Thank you, I will use this when my dad is sneezing so we could power the city.

gonna use the energy of my screaming family

Monster's inc. was trying to tell us this the whole time! Scream energy man!!!

Now that's an interesting way to use a rotating shaft to drive a lineal generator. Nice work.

I have read quite a few comments, and haven't seen a single person mention replacing the electric motor with a geared wind turbine, or even some kind of simple waterwheel. All you have to do is spin the magnet, the motor isn't important, it's the spin. It's not going to power a house, but in a grid down situation, it might be a useful way to use scrap to generate light, or even charge small batteries. You don't have to power a whole house with every nifty generator people can think to make, sometimes, small power is useful all by itself...

Hi Giesberr, I found really awesome your video, and I'm actually doing it for a Science project, I just have 3 doubts: 1.- what kind of speakers did you used? 2.- you mentioned the frequency of the speaker, is it relevant to light a bunch of leds with your prototype? 3.- what would be the frequency or how do u set the frequency?

Hi Giesbert. A typical clear blue LED as you used are designed to operate at around 25mA with a forward voltage of 3.3V (See Kingbright L-7113QBC-D Datasheet). Since you didn't have a resistor connected to limit the current you would not have had voltage division and looking at the brightness of the LEDs from your video you would have been close to between 20 and 25mA I guess. So, if you would have measured the voltage across your LED array which from what I can tell all LEDs were connected in parallel, you would have measured 3.3V which would be the same as across the coil. With 100 LEDs each drawing 25mA you would have generated around 2.5A at 3.3V. Calculating the produced power, P=I*V this gives 2.5*3.3=8.25Watt. Obviously the actual power developed will be lower since you only used halve wave rectification. I think it would be worth your while to measure the motor power consumption (V and I). You might have a fairly efficient little experiment with more to it than you realize. You could use low voltage schottky diodes to achieve full wave rectification (you can get ones with a forward voltage as low as 0.25V), which means you might only sacrifice around 0.5V and thus still have enough to exceed the minimum LED voltage required. Cheers, Gideon

You have created the mechanical equivalent of a wireless power transmitter and receiver :) .

is it possible you can give us the amperage and voltage generated? is this setup electrically efficient?

I can see that you have gone to the fundamental theory of Faraday's Laws Thank You MAY THE ALMIGHTY GOD Be with you

Your experiments are great. I would suggest that you include explanation for every step or process of your experiment though.

This is the secret of the universe, sound is the source of and creator of all life. Great video!

Love ideas like this. Wish I had an electrical engineering brain to think up stuff like this too.

If you use magnetic motor instead of electric than it's free electric power energy :P

Depending on how the LEDs are arranged, you have a half wave rectifier with a giant current draw. For generator purposes, you really only ever want 4 diodes and even then, only in a bridge conformation. As far as this goes, I think you have the beginning of a good microphone. You need transistors now to amplify the signal. there's some DIY non-contact voltage detectors that have some okay ideas on how get some amplification out of a transistor array.

duct tape your vibrators to your home stereo to power the house...lol

Awesome experiment! Thank you very much for the demonstration.

If it's crazy but it works, it ain't crazy!

isn't that using the energy of the magnet instead of the energy of the motor?

My physics teacher teached us a little bit about generators and electro magnetic fields the last few weeks now , and I've never been so "into it" I find it so interessting! Awesome project by the way!

dont power the Light but power the electro motor it self!

This is awesome man!! Can you make a speaker = generator that can run on like plane sounds or car engine sounds ? like nuisance sounds also I was wondering if you think this would work like a rectenna for radio frequencies 2023 feb 16

Great Idea! One suggestion 1) You should make the green bands out of piezo electrics to get more power output

great idea but isn't mo energy is lost from turning the moter???

any idea on the rpm's that motor was running at during the recording of the video? just curious to see how much it took to power up, and drive the generator for the 100 led's worth of current.

It don't works with parallel magnetic field

try a smaller motor such as the one used in mobile phones

this just helped me realize a bump in my research and its going to make my school science project easier. correction it has already made my science project easier thanks alot

This is one of the most genius and innovative idea i have seen on youtube

sir please ,given the list about these material

have you tried an mp3 player playing a hum (in a loop )at say 60HZ? or what ever... and placing the speaker over this " cut-out " you have made?.

genius

What things you use in this? Please tell.

This could allow unlimited battery life in drones which is just amazing. And possibly in smartphones.

la energia que le entregas al motor electrico es 10 veces superior a la que se usa para encender los led que son de alta eficiencia, bajisimo rendimiento no sirve para nada solo para aprender fisica y experimentar

Just about anything with electromagnets and permanent magnets This is in fact how an electric guitar/bass works

Amazing! Please reffer me to books or sources. I want to learn the physics and mechanics of it all so that i may join and benefit this pioneering community! . Many blessings!!

Clearly you have a different idea of what the word 'continuously' means.

that will be good if it 220v/ AC

Hi Giesbert, Your experiments are neat but I am more interested to help you walk again. Have you researched "Grounding." Have a real good quality, deep, ground connection made and ground yourself. In one video I watched it shows one person who hasn't walked in 20 years, and after being grounded for a while he stands up and walks. Joe Dispenza, a chiropractor from California, a remarkable person and the author of "Evolve your brain" broke his back in a triathlon and was paralyzed from the neck down, healed his condition by staring at a picture of a perfect skeleton. Please check it out. The Earth is our Mother and she is a healer. I hope it works for you. Sending you good healing energy. Peace and light.

this is a good one! when you say sppd is senstive just what speed are you using with the motor....rpm

How about using speaker coils on a hydraulic ram pump to capture the energy from the the the unit when it forms a pulse of high pressure water

great video, nice touch showing the magnetic fields graphic!

Nice. I like the demo. Mine was more complicated than this. You win - now I steal it... :) FYI - this is the premise of the original "telephone". Bell only really patented the speaker, and he wanted this EMI voltage to be the full source of the sound transmission. Didn't work. Edison had the carbon microphone. The rest is history.

Yes! I love it! Anything that is powered by electricity can also produce it. Not only does this prove what the ancient Egyptian tuning forks and staffs were used for but this also shows us some secrets to free energy and proves Tesla's "theory" was actually fact. However I think it is wicked that many scientists have known for an extremely long time that frequency is the key to clean limitless energy, how to produce it, and instead of using that tech it's hidden instead. It's obvious why.

Hmm now I'm thinking that with todays tech we could make a cloth or something that generate energy from vibrations. The clothe could be made from microscopic pieces of copper spaced using a math formula for efficiency. This fabric could for example be placed under a car or on a roof to recuperate energy from the wind/vibrations.

Try kid playing the drums. Try kid punching it like a heavy bag. Try kid picking up a 15" sub and slamming it wwe style. Try a lot Dude. Roll it down the steps. Pretend like someone is choking a chicken, yup I said it! Love You, Brother!

woooow...!!...what a nasty mind u have.....nice.....try to wireless transmission of electrons....I m failure yet like Esteem Tesla....have a nice job ahead.

VIBRATION DRIVEN GENERATOR, now only if i could scale this up to absorb earthquakes and japan here i go

I don't know if you still read the comments here but I wanted to know if this speaker generator could also be used by simply just using sound. Could you please tell me if I'm correct?

That is absolutely AWESOME!!! Just, WOW!

well thank you dude... i have an idea from this video...

Will it work?

😂😂😂 Le mete un potatoes y recogerás seeds ¡Su próximo invento! A logrado demostrar de la forma mas complicada posible,de crear pérdidas en la conservación de la energía

Speakers are terible as liniair alternators, Even whit a 250watt subwoofer i was not able to generate more than 20 watts at 38hz on a 12 mm displacement

That seems like a good idea. Any specs on the kind of speaker I could use. can't experiment here and ruin the speakers.

Now you just need some electricity to power your generator... Amazing! *HonK*

But in practical we won't get the intensive sound waves that can vibrate the magnetic diaphragm coil... We should convert even small sound to the respective voltage then this experiment have some importance other than that it is simply a "dc generator with a dc motor excitation"....

What are the materials?

I thought about this one day, I bet people will make enormous powerplants made from the same concept and create huge amounts of energywhile not creating so much waste

The concept of this project is how to convert sound energy to electric or energy mécanique Please answer me.

ЭНЕРГИЯ -ДВИЖЕНИЕ.....НО ЕСЛИ ЕСТЬ ЭЛ.НА МОТОРЧИК ТО НАХ ЗДЕСЬ ГЕНЕРАТОР ДЛЯ СВЕТОДИОДОВ.)))...ВОСПОЛЬЗУЙТЕСЬ ХОТЯ БЫ ТЕМ ЧТО ЕСТЬ С УМОМ.!..............

You did not have to cut the membrane

How many revolutions per minute did the engine turn? And how many volts and amperes would be reached?

well this answers my questions

Can u plz explain the concept I want to do a project like this for science expo

uh, how bout you unplug the motor from it's power source and plug that same source to the lights? you know, cut out the middle man.

Ok so obviously it's not the sound generating the current, it's the magnetic induction through the copper windings causing the lights to turn on

wow that's so brilliant. it's like an ufo or aliens technology.

Hi this video is amazing I have a question How can we generate power from sound ?

Nice but you have illuminate lot of led where is power come from

Pour children from africa coud eaten thjs speaker!!! what have you done?

What was that blue line over the speaker. If we draw a imaginary line from the centre of the motor it was on its place .

is the small current motor not cheaper in using power? :) for lighting the house :D

Can i know the materials needed for this product? :)

Aaaaaaa?? Nope,but if so it could power itself?! I think.

show led amps n motor amps after that technical mind is going to think about it n you didn't mansion how may volt each led

Generators in power stations can be rather loud, why not stick a ton of these on them to mop up the wasted sound energy?

Just thinking, should have used the excess power on the motorised magnet.

Why did you cut some parts from the diaphragm speaker, like the cone?

Very Nice 🇧🇷

this is really interesting, i just wander now how many V this generator give?

Nothing really special here get the same affect, passing a magnet over copper

Maybe we can dance the night away, David Lee Roth style generator.

C-R-A-Z-Y !

U STOLEN MY IDEA OFOFFFFFFFFFFFFFFFFFFF i am happy my idea does work tho

This is interesting but it's just another way of transferring energy source.

Merhabalar Güzel bir deneme . Pinpon topu ne için diye düşünürken :) aklıma takıldı Buna benzer şekilde lastiklerle bağlanan bir top düzeneği ile denizde bir duba içine yada altına bağlayarak dalgalardan pasif elektrik alınabilinir mi sizce ?

Спасибо автору.

I like it

Attach it to the ceiling to harness the power of the upstairs neighbors!

Could you hang a large shaped magnet by a string and the constant repulsion would cause it to move around continually generating electricity if its balanced properly?

you know, saw a video here in youtube showing and inventor and his invention of ambient sound converted into electrical energy, in the video, he powered a taller than man frig and his house aircondition system with the electrical out put of his generator, it can generate large amount of voltage even in a night time ambient sound where you can here a drop of water at far, just ambient sound created kilowatts of usable electricity. what ever happen to that invention, i don't know but i couldn't find it anymore.

It would be interesting to connect a ribbon with a connection to the speaker either mechanical or magnetic repulsion as you did with the motor.. Place it outside and let the wind move the coil up and down to generate the current spikes.

why does it light up? is it like a piezo speaker? or magnetic one? could you help me understand? Thanks a lot.. cool video

ma la corrente che consuma il motore per girare? nessuno si è accorto i fili che partono dal motore per andare verso una batteria

Bhai tu jitana energy de raha hai utana energy paa nahi raha hai ---> is not free energy 😂😂😊

What kind of speaker did you use for it?

Ok. But you still have to power that little dc motor.
