It's a 'decent' explanation if you know electronics or if you know how a speaker works already. Otherwise I have to agree with the layperson that it just shows you what a 9V battery does to a speaker. What's the point of that? Also, for anyone that cares, it is the same principal for a woofer, subwoofer, tweeter etc. There are also different types of speakers that work in different ways. Starting to get confusing? Perhaps another video will do a better job of explanation...
wow speakers are that simple? well the device itself is simple but the computers/ radios have to do tons of processing to get the music we know and love. imagine when a guitar, a singer, a pianist are all making noise at once. the speakers has to replicate all those natural frequencies. it doesn't seem like much but really its quite amazing. it is the ultimate instrument lol, humans just can't play it
Oh my god, I am so enlightened. Thank you for educating me. Now, if my friends wonder, I can tell them, if you use a battery on it, it will move, and they will be impressed.
People do NEVER attach a DC supply (battery), because the voice coil will freeze in inner or outer position, and then wont be able to get the heat away, and then eventually toast it self.
Use a AC current (from a MP3 play output, or amplifier), Because AC is in constant change between postive an negative, so the speaker cone will move back an forth. Therefor most of the elctricity going through the speaker, will transform into kinetic energy instead of thermal. And will remain much colder.
@Qube1 You can actually use this to determine positives and negatives on unmarked crossovers/speaker terminals. But you can only do it breifly. While speaker coils do depend on movement to cool them down, such breif 9 volt pulses to it shouldn't hurt it - And 9 volts isn't much at all, so it is not much power going to the coil. Although you are right, doing it breifly and only once or twice will do no damage (unless you are using like a 1" earbud speaker :P)
Yes, but if you actually want the speaker to have a long life than it's very dangerous because it also gives the speaker 1,800 watts, and depending on the speaker, that could kill a small speaker in a fraction of a second, and it'll take several seconds or a few minutes to destroy a normal car subwoofer. That's the fastest way to kill a speaker other than physically smashing it.
There is a powerful permanent magnet in the back of the speaker and an electromagnet coiled around the front, when electricity is flowing through the electro magnet it creates a magnetic field so it is then attracted to the powerful magnet in the back and it moves the speaker's "cone". this would create a sound wave, if you did this fast enough you could create a song, i think tones move the cone a lot or a little to create a high pitch or a low pitch.
It doesn't really explain how a speaker works, but it does demonstrate what excursion is (though they never said excursion). This is a good video but far too simple and it needs to be more technical! Although the experiment is a good way to test if a speaker is blown and you don't want to risk an amplifier : ).
ok folks,duh i have used this tec tip for years to find the polairty of factory speakers. + on battery to + on sub, will bounce outward this is correct. switch battery will bounce inward like theese dumb asses did. floks a great way to find + - on unmarked speakers...
i got a question sir if your speakers got wet and you were to try this is there a chance of you getting the shock of your life even though theyve been dried for a good 3 days?
that wasent very informative but i think the bloke who invented speakers is a very cleaver person how would u know how to make a serton kind of power to make a bit of copper wire and a magnet make a sound like a human voice
Sound are actually vibrations in the air. If there are more vibrations per millisecond in the air it produces a high frequency, If there are just a few vibrations youll hear a low frequency. A speaker has a Electo magnet, and a normal magnet. If you activate the electro magnet (by sending electricity trough it) the speaker generates vibrations.

Best to use a 1.5V battery for this, a 9V battery will drive most speakers to their excursion limits and possibly damage them.

Wanna know how a speaker works?
You plug it into a 120v socket and you get a wonderful sounding 60hz Test Tone!
Works for every and any type of speaker
From Sony and JVC's on up to the most expensive Gryphon and Goldmund drivers.

i don't understand how it produces different sounds (tones)... I guess I'll have to research it.
fijberto 2 years ago
Simple:
Insert an electric frequency to the speaker coil, and you get the equivalent sound frequency.
(Frequency in this case is a vibration)
Different frequencies gets different tones
Low frequency gives a low pitch tone.
High frequency gives a high pitch tone.
