Teacher explains High-Def Speaker for Under a Buck

[yuckalonius]

Search youtube for HDD Speaker(tune up) to see an interesting homemade speaker out of an old disk drive and cd case.

[yuckalonius]

missionphoto, I like your video, and appreciate what you're doing.

Everyone else. 1st of all, I wouldn't use a nice receiver to test this on. 2nd, householdhacker is just making parody videos. He even says so in at least one of his descriptions. Finally, "hi-def" labeling of sound or radio is like "natural" on groceries. Hi-def is a specific standard for video, and just used to sell stuff for everything else. To get "high definition" sound, become an audiophile.

[TheSupertecnology]

so what´s the difference of normal wire and magnet wire?

[1anric1]

Can i ask? Where do you put the wires of the audio jack?

Please reply man, I realy, realy, realy neeeeeeeeeeed the answer!!!

[TSSKTV]

I like this guy, keep doin wat cha doin dnt let haters drive ya

[Alkinoos7]

good one, at last somebody to clearly explain and make a proper experiment...

[passionguitar666]

[TechnomTigerGeek]

house hold hacker = POWNED

[IntoTheDimension]

The worst time to release a video is April 1st.

[shadowz116]

Man i wish i had a teacher like you in 6th grade haha.

[Ilost11]

if u really want to get speaker for a buck go to a dollar rama

[dmavideohops]

another faker!!!

[brandonarcher1]

It is absolutely not busted, because after seeing this video I added the magnet and got extremely clear though very quiet sound out of my paper plate speaker replica. For those who want to try this I say go for it, but fair warning; you may not be successful depending on what sound source you use.

[ManaBleach]

Note the date of upload.

;)



[brandonarcher1]

I actually tried the make a speaker for under a buck. It didn't work and I felt stupid for believing it. Then I watched the myth busters video and realized that they were even stupider because they just gave up and called the myth busted.

[WoofterJM]

Ok?

I must be doing something wrong. I have my permanent magnet taped to the foil directly under my penny. I have some cheap old headphones that did work before I cut the ends off. I wrapped the exposed wires around the penny so that the wires are from end to end on the Abe Lincoln side and halfway across the tails side. I then taped the penny Lincoln side down.

I suspect the headphones, what kind of headphones are you using? Should I risk my old apple headphones?

[wtbyguy83]

@WoofterJM if the headphones didn't work the wire could of beenbad not the headphones so explaining why the both don't work. this guy here is right you can made a speaker out off almost anything with magnets

[123masterlink456]

wow i aculay learned smothin on youtube

[unknotmiguel]

every fake videos (for joy) should e reported and banned by law in youtube.

Fake = loss of wisdom, and gain of wrong beliefs, which is totally against evolution of specie.

[gundeep0]

if u realy want to make it then mount a bigger magnet to a plate such that it is very close to the foil but not attached and its magnetic axis should b perpendicular to foil and the part of foil just above the magnet should have an electromagnet attached to it such that its magnetic axis coinside with that of permanet magnet, the two terminals of electro magnet should be connected to 2 wires coming out from the head phone

[gundeep0]

and i m an engineer so i kno how speaker works

[STANTL3R]

@gundeep0

yet you cant spell "know"

[gundeep0]

if u read my previous comment then you must have seen many words in short form. if you really suck in reading short forms then either do not read/ write comments or try understanding them.

(for you to understand i hav not included any short forms in this comment)

[STANTL3R]

@gundeep0

WuT??

LoL?!1

IdK WAT UR SAYINNN!!!

LooooLlLOlololOLolOLolOLoLOLZZ

1!11!11!!!!!!!!!!!!1!!11!

[gundeep0]

,,|,,

[2BSilveR]

The idea works cause you got all the components , but he put the magnet and the penny on the foil, i would assume putting the copper on the plate or something would be better, otherwise where will the vibration come from?

I saw no vibration in this video, so i doubt the authenticity of it.

And i have no idea if a penny can be used as a electro magnet or not.

[Noobage211]

Wow hexan. your a dick

[jitzero]

can u use a plate not out of paper? ie pot

[missionphoto]

heXan, it is not a "magnetic wire" it is a "magnet" wire. That is the type of wire. Go to Radio Shack and ask.

[heXan]

*DOH* would best fit your reaction when u'll understand what i wanted to say... the guy in the vid says that's a so-called "magnetic wire", not a "normal wire". the point is that a "magnetic wire" is just a isolated copperwire. therefore it's a "normal wire" but just isolated.

there's no real difference in these two "wiretypes" if u could name them this way. the magnetic field properties, when electricity or an external electrical field is applied, are in "both" wires the same.

[heXan]

the only difference will be in the solenoid. if you don't use an isolated wire(just a wire, not a super-duper-magic "magnet wire") the charges loaded onto the circuit will only induce one big charged potential area with a minimum magnetic field. if you use an isolated wire instead you'll get the desired homogeneous magnetic field inside the solenoid and at the edges of it. that's the hole thing.

[heXan]

"This is not a wire. It's a MAGNETIC WIRE..." ROFLMAO... every wire caring charges is a "magnetic" wire... what a dumbass

[potheadpenguin]

wouldn't you be better off putting the magnet on the plate rather than the foil so the electro magnet has something to work against.

How I see it is that having both magnets mounted on the same surface would be a bit like trying to push yourself over... it just doesn't work

[deathshadow790]

mine doesnt work. i did it exactly how u did it and not a sound. im using my guitar amplifier, which is plenty powerful. what am i doing wrong?

[MichaelJHuman]

Totally legit speaker. Maybe not as good as my Audio Concepts speakers, but much, much cheaper.

Too bad it did not get louder.

Volume is about moving air, and this speaker design can't move enough air.

[charvelgtrs]

Yeah, this video seems legit.

Overall speakers are not that complex in design, so I can by the fact you can produce sound with those materials he used.

Doesn't mean it will sound as good as mass produced speakers, but that isn't the point. The point is that making a homemade speaker really isn't that difficult.

[acnespider]

lol 6th grade teacher

[rockerzyx]

phones ringing lulz 1:30

[MaverickXIII]

i just went back to sixth grade science :O

[BEEboyKICKS]

fail

[imbrd]

paper plates dont transfer nor contain sound well- need something harder/denser

[jayholley123]

if you eint a idiot just buy a speker

[mccoolrecords]

hell yeah

[yiaroxx]

ahha MR.Trip ahah

[sweetyvash]

very informative, not like the other dumbtweet video only their shakey video is showing and when their finish making the speaker you would believe its true coz of the quality of the sounds it makes,until you tested it yourself...lots of asshole out their want to ride the bandwagon

[TongeMoorJonny]

fuck sound make the SPEAKER

[danrulz98]

This looks like a good way to toast your stereo

[Malfunction0982]

The quality sound sucks

[haxor179]

whats the point of making a paper speaker when its really a big ass ear phone its not really useful

[Zodiacx10]

i followed the directiton and it doesnt work

help me

[acronus]

There are a couple possibilities. The copper wire needed is the type that has a very thin coat of lacquer on it. If it's just normal copper wire, it just shorts out the signal source. Also, the distance between the copper and the magnet makes a big difference. The field of a magnet deceases ten fold when the distance is doubled.

[dougerb09]

penny has to be pre-1984 because of the copper.

maybe thats why??

[UNTAMEDmtcj]

It's actually 1982, and not it doesn't have to because even the now ones have a thin coding of copper on it, that's why it looks copper.

[dougerb09]

thanks you must be really smart

[Jack2208]

you missed the phone!

[Gamestar73]

lawl, i heard it ringing and ran upstairs thinking it was my cell =P

[stemcellfilms]

you and your video are awesome, god bless education and the power of the human mind. This will all matter and we'll use this someday, when babylon falls...

[yariff]

what is the matter with you???

[ByteSmasher]

Simple hands-on experiments like this help people understand some fairly complex scientific concepts that are useful in many areas. Your sarcasm simply shows ignorance.

[whiteboy1295]

WTF? is wrong with you, its YOU kind of people the world needs to be worried about.

[p4cm4n182]

imma destroy my speaker to get that electro magnet then make that

[mashangg]

SO SUCKSSSSS. ITS ALL FAKE

[acronus]

No, this version of the paper plate speaker will work. It has all the principal parts of a normal speaker and will generate sound. As for it being "high fidelity", that is the part that SO SUCKSSSSS.

[johansmyface]

if you can get it a lot louder and able to play on MP3's

that would be awesome

ive tried so many diffrent expierements but theyve all failed

but what can you expect from a junior in highschool

[erixjin]

well i want it stronger lol

[magookicksbutt]

can u use a normAL MAGINET??? please reply

[missionphoto]

You can use a regular magnet, but rare earth or other strong magnets work best. If you can find a big magnet from an old speaker, they work pretty well.

[xscottx019]

if you use a bigger plate and a bigger magnet would it be louder?

[FoxTv689]

Well, Bose employees, see ya in the unemployement line!

[Adelbert1309]

Nice video!! BTW what if I will use a larger maganet or an electric magnet to produce much louder sound? ☺

[brotherOfSmash]

but salt does lower temp. But yeah fakeo househacker!!!

[AlienRelics]

Why it works at all with the wire ends simply twisted together: it acts like a one turn coil electromagnet.

You need to separate the magnet and coil. With them both fastened to the foil, there will be only a little sound due to vibration because the magnet and coil are taped loosely.

Tape the magnet to the center of the paper plate, then tape the coil exactly above it on the foil. Carefully push the foil down so the coil is just above, but not touching the magnet. It will be much louder.

[ShadowRoulette]

Can the magnets and stuff be found inside the headphones you are splicing?

[missionphoto]

The headphone has its own magnet, but it is very small, you need a more powerfull magnet.

[missionphoto]

DracoEX, are you talking about RCA cables? I tried that, and they were not much better.

[missionphoto]

Do not put the wires together. The penny is not that necessary, as I mentioned, you can roll some wire up and that works even better. Watch some of my other videos on speakers. Again, I never claim this is a high-def speaker, I just tried to show how it could work. Thanks for the comments.

[DracoEX]

BAKA! a hedphone jack Wont work because the wireing at the plugin is made to reduce sound!. i k now i did the same thing trying to splice a aux to headphone jack together and there wasnt enough sound to make paper vibrate!!

you need to use a diffrent cord that was designed for thing kind of thing like pc speakers. after i spliced old seaker wires with the same aux cable and it made it extreamly louder! SO PEOPLE TRY THIS if your not getting the right volume of sound.

[kedonot11]

Householdhacker just got owned..

[GRINDKINGBOARDS]

@kedonot11 no he didnt be cause household hacker made it for about 3 bucks this guys was made for about 20 bucks and just because this guys is louder does not mean anything ive made a speaker and it works fine and i use HH's instructions so no he didnt get owned or anything.

[airman1717]

does the household hacker one work?

[baronblod2003]

You can do it with regular copperwiring also. You just have to remove the thin layer that surrounds the wire. A thin layer protecting the wire needs to be burnt or scraped away.(No I am not talking about the plastic). Good video though. Keep it up :)

[StuntPeanut]

plate-speaker* :x

[StuntPeanut]

Hmm if you are going to plan on making more videos about this topic, you should attempt to make a plater-speaker that can actually serve as a real speaker.

[quickattack]

mmhmm...ok, i'm gonna need to go get some wire. another question, perhaps he answers this in the other vidoes, but does he put the wires from the jack between the penny and the foil or between the tape and the penny?

[missionphoto]

You have to put the wire between the penny and the foil.

[quickattack]

ah...that's another the householdhacker didn't do. he put the wire between the tape and penny.

[therandomjohn]

This is on April 1st. If it's a coincidence, then tell us. If it's a real april fool's prank, tell us.

[missionphoto]

No, this is not a joke, it really does work, but not that well. It's a paper plate, you can't expect that much. Check out my challenge that I have for my students. In a few weeks my students are going to create their own speakers and I might share some of them.

[ManolisSkywalker]

Added: April 01, 2008 lol

[Amnesiam]

1st April... That's funny man! =D

[missionphoto]

You don't really want to connect the electromagnet (EM), there should be some seperation between the EM and permanent magnet. Watch my other videos, I explain more. User Zenodilodon replied and made a pretty good speaker.

[lukichu]

they dont put in a magnet

[halomizer]

My grade 11 electronics teacher did this with plastic cups. Science teachers are always the coolest.

[motaries]

great review, i can't believe you are a 6th grade teacher. Your knowlage scares me, good job :D.

[soccersurfdogjack]

where would i get a rare earth magnet

and how much do they cost?

please reply this looks so cool

[mrkiky]

You can get them at dealextreme . com .You can also pull them out of old harddrives.Btw, this doesn't work because the speaker he created is shit, and because he needs and amp.The signal from that jack is meant for small headphones not for a huge coil around a nail.

[missionphoto]

I agree the speaker isn't that great, I wouldn't surround my house with them. The point of the video is to show people that you CAN create a speaker using household items. I never claimed that this speaker is High-Def..I'm just showing my students and the world that it works....thanks for your comments.

[missionphoto]

You can get them at Radio Shack, 2 for $1.99. I think you can also get them at most hardware stores.

[tharrington11]

wow sorry for saying it wouldnt work, i tried it and ruined me good speaker jack cord. but why didnt it work for me? but it worked for you?

[missionphoto]

you need an permanent magnet on the bottom, rare earth magnets work best. I found out the magnet must be directly under the wires for it to work. Get rid of the penny and take some thin speaker wire and wind it up as much as possible, then put the magnet in the middle and that might work as well. Check out my other video "speaker under a buck challenge part 2" Thanks for watching.

[IckyThump85]

wow thanks man that was cool

[Zenodilodon]

Speakers run on the push pull effect of EM signals going through a series of wound wire coil. To make this even more effiecnt you would want to actually remove the penny and the electrom magnet form the foil, glue or tape the magnet to the foil as shown here but before you put it over the plate mount an electomagnetical coil in the plate so the magnet sits on top, I may to this with plastic wrap to demonstrate this type of set up very nice video btw thanks for letting people know the truth.

[missionphoto]

Thanks for the input, I am teaching EM waves to my students next week, I will bring that up. I'm not sure if the plastic wrap will be tight enough. I tried it and I could not get it to work. Let me know if you can, I would love to see it work better.

[mannymax]

NICE

[SestraAnka]

Thank you for describing everything! Peace!

[ffantasy36]

Why are there still people that believe HouseHold hacker's speaker worked? Some even claimed to have tried it and succeeded! Excellent video by the way.
