How does a speaker work?

Basically the movement of the speaker is the cause of the stereo (mono speakers) making the noise via induction. The Induction is the result of controlled oscillation of electrical current. A speaker is essentially an air pump. I like to say the bigger the pump the bigger the sound!!! A driver is a device that reproduces sound. Drivers consist of woofers, subwoofers, tweeters, midranges, compression horns etc. A driver consists of a magnet assembly, a metal or composite basket/frame, coil and cone or dome. A driver has a coil of wire that is electrically attached to your amplifier. The coil is the electro magnet not the magnet itself. The magnet is usually made of ceramic but used to be made of Alnico (Aluminum, Nickel, Cobalt; expensive compared to ceramic) and is more often now made of neodymium (a lighter stronger material than ceramic). The magnet has a permanent magnetic polarity that does not change. When the coil of wire is placed inside the magnet assembly "pole piece" and an alternating signal is placed thru the coil it will cause the coil to oscillate as the coil will now attract and repel within the magnet assembly as the polarity changes on the coil. The coil is attached to a cone (or dome in the case of tweeters and some midranges) which is capable of moving air more effectively. Speakers consist of these drivers usually a woofer, a tweeter, and sometimes a midrange. A speaker will almost always also have a crossover network which is basically a filter network that effectively divides the signals to each driver so that the bass only goes to the woofers and the high freq only goes to the tweeters. Typical speaker arrangements contain multiple speakers: two for a simple stereo system, or more for more recent systems. All multi-speaker systems need observing the polarity such that the coils in all speakers make the same, synchronized, movement: in a multi-speaker system, some sounds only come out of the left speaker, or the right speaker. That makes the stereo effect. The majority of the sound, however, is being emmitted through all speakers at the same time. The bass drum, for example, can typically be heard through the left and the right speaker at the same time. Wiring all the speakers in such a system while observing their polarity allows the speakers to make a syncronized movement. For example, when the bass drum hits, all affected speaker coils would make a movememt towards you, then away from you, etc. If one of the speakers is wired with the reverse polarity, this speaker would start by moving away from you, then towards you. Air would simply be shifted back and forth between the speakers, instead of applying pressure on your ear drums. To avoid that effect of lost sound energy, speakers should be wired up with the same polarity even though they are driven by an alternating current (AC) signal. Additional Another type of speaker is the electrostatic loudspeaker . Electrostatic loudspeakers are generally very much more expensive than the electromagnetic loudspeaker described above and, in most cases, far superior. Physically, they look completely different from conventional loudspeakers, usually taller and wider, but very much thinner (rather like a plasma television compared to a CRT television!). Electrostatic loudspeakers work on the principle of attraction and repulsion between electric charges. The general principle is as follows. The diaphragm ('driver') , a large rectangular flexible sheet of material, such as mylar, is coated with a conducting layer and placed between two large metallic perforated sheets. A high DC voltage is placed between across this arrangement and the audio signal is impressed upon the voltage, causing the polarities to change in magnitude and direction in accordance with the musical signal. The result is that the flexible sheet will then move, acting in much the same way as the diaphragm described in the previous answer. Compared with electromagnetic loudspeakers, the diaphragm is much lighter and reacts far more rapidly to variations in signal. Furthermore, because the whole of the surface of the diaphragm is charged, the resulting forces are applied to the whole of the surface of the diaphragm rather than being 'pushed' or 'pulled' by a separate coil -as is the case with the magnetic loudspeaker. Like electromagnetic loudspeakers, electrostatic loudspeakers also have 'woofers' and 'tweeters' -different-sized rectangular diaphragms. Because electrostatic loudspeakers require a very high voltage (thousands of volts) to operate, they each have a heavy built-in transformer and rectification system and must, therefore, be connected to an electricity supply. Electrostatic loudspeakers were developed, commercially, by a British hi-fi company called Quad , which has been manufacturing them since the 1950s.

How do speakers work?

Speakers work by turning eletrical energy into sound. Speakers are an electromagnet that connects to a paper cone which moves the cone which moves the air. This is how speakers work.

Why do you want to work in the information technology field?

I want to work in the information technology field for the following reasons: 1 - Secure field of work 2- good starting salary 3 - numerous job titles/positions within the field of information technology 4 - My concentration for my master's in Information Technology is Networking. Networking computers allows me to work with technology, but it doesn't require me to write codes for software; something that would be way over my head, I think. 5 - I'd love to major in Computer Engineering or Computer Science, but I just don't think I have the level of intelligence for that; Information Technology is the next best thing if you're interested in technology. 6 - Education, industry, government, non-profit, and others all rely on Information Technology. Even the library has an IT department. Because nearly every business needs information technology majors, you can live wherever you want without worrying about finding a job; you can find a job in this field no matter where you live! I am starting the Master of Science in Information Technology program at NC A&T in Greensboro, North Carolina this fall. It is offered completely online and their tuition rates for online programs are the cheapest I've seen anywhere! This particular department within the school does not even require the GRE! The program requirements are 30, 33 or 36 semester hours depending upon whether you choose the thesis, project or course work track. I'm doing the course work track, so I'll be taking 36 hours. Good luck in your career/educational endeavors and if you haven't made a definite decision already to get into the informational technology field, you really should consider it. It's an excellent field of work!

How does a speaker works?

Answer . A speaker consists of one or more magnets, called voice coils, which are mounted at the narrowest part of a cone(s). The cone may be made of paper, cardboard, or Kevlar. When the amplifier receives a signal, it amplifies it, creating current. The current causes the magnet to move, which distorts the cone. When the magnet relaxes, the cone returns to its original shape, after a few oscillations. The cone moving back and forth compresses the air in front of it, causing a wave to travel away from the cone. That wave is the same frequency as the signal the amplifier received.

How would wireless speakers work in a motor-home I want more speakers for in the cab thought wireless speakers would be good. The speakers would be played through a standard cassette car streo.?

How speakers work?

Power Source . Speakers do not have a dedicated power source of their own. They draw their power from whatever it is that they are connected to - be it a CD player or more complex stereo receiver. Any one of these pieces of equipment should be able to provide enough power for the speakers to be able to be used to their full potential. If they don't work well together on their own, an amplifier can be purchased and connected to the system to make up any power that may be needed. Sound Information . Without a way to process sound information, speakers would have no function. This is why speakers are always either built into or connected to something else like a compact disc player or a stereo system. These pieces of equipment process and convert any sound information they receive (from things like the radio, CDs, DVDs) into an electrical signal. This signal is what is sent either via a wireless connection or through dedicated wires to any speakers attached to the system. Playing Sound . The electrical signal is then used and outputted by the speakers. What we know as "music" and "audio" is very simply the speakers playing a frequency of noise that is constantly changing. Our brains can process this information for what it is (voices, music), but it really is nothing more than noise. Settings like overall volume, base (lower frequency information) and treble (higher frequency information) can be adjusted on whatever device is sending the sound information to the speakers.

What can be done to increase cars fuel efficiency?

There's the basic's like keeping your tires inflated to the correct pressure, replacing your spark plugs/getting a tune-up, keeping an eye on your driving habits - don't speed up to red lights, don't put the accelerator to the floor if you don't need to, etc..., replace your air filter. I started using a fuel catalyst about 7 months ago, and have seen about 10-15% increase in fuel economy consistently. It helps your engine burn fuel more efficiently. The one I'm using is Fuel Infusion - http://www.fuelinfusion.com. Good Luck! . There are a few things you can do to get your car more fuel efficient. One of the things is to use a fuel catalyst. These catalyst are great and will save you money in the long run and make your car more efficient. lets see, you can start by not driving to fast past the speed limit, you should not have your windows down if your on the highway because it decreases fuel efficiency by causing friction

What Electrical signals convey information?

Electrical signals are either direct current (DC) or alternating current (AC). For DC signals, information is carried by the existence of a DC level, or it's absence. This is binary signalling, and communicates either a '1' or a '0'. An AC signal conveys information by either changing one of the three properties that AC signals have: 1) changing the amplitude of the signal (this is amplitude modulation, like an AM radio) 2) changing the frequency (this is frequency modulation, like an FM radio station) 3) changing the phase of the AC signal. This is used in the faster of the old-style computer modems, as well as DSL modems

If you want to lift a 5kg box to the height of meter how much work must be done?

Did you say one meter ? You'll have to give the box 49 joules of additional gravitational potential energy. But since the human muscular system is not 100% efficient, you'll have to spend somewhat more energy than that in order to do the job. The additional energy that you put into the effort will show up in the form of elevated body temperature, increased heart rate and blood pressure, and warm perspiration on your brow.

What message did Shakespeare want to convey in As You Like It?

It is highly unlikely that Shakespeare intended to convey any message in this play. As You Like It is a comedy which is primarily designed to entertain. Shakespeare made use of a number of conventions, apparently without irony, such as the conventions of pastoral literature, the cross-dressing girl, the melancholy man, the evil brother usurping the throne, and the play ending with multiple marriages. Looking for a message in all that is like looking for the message in an episode of Cheers or The Beverley Hillbillies.

What can be done for the kidney to work at its best?

The liver is the organ in the body that secretes bile and neutralizes toxins. These have to go somewhere. That's where the kidney comes into play. The is the organ that excretes urine. Urine? liquid. Liquid? Like water. drink water through the day. You don't have to walk around carrying a bottle of water every day. What a sight! Evian. Spell Evian backwards and you'll see. Ok, back to the subject. I worked outside in 110 degree weather in Texas. I love warm weather. I was in and out of the sun replacing a motor in a 1972 Chevy pickup. My only breaks were going inside and refilling my container. Hint: it's a plastic bottle that used to carry alcohol. Used it up and washed it and filled it with water. I worked from 0800 to about 1600 hours and didn't even notice that I worked through lunch. I drank probably about 2 gallons of water during that time. Water helps the kidney tremendously. Stay away from foods that are toxic (for lack of a better word). If you can't, drink grape juice. It helps a lot. Years ago when I lived in San Antonio, Texas, I filled a big container with tap water and placed it in the refrigerator. The chemicals like flouride and such evaporated and when I took some to drink, it was good tasting. Have water handy, always, you don't have to buy it at the store. (Evian - wow!) Make it part of your lifestyle to drink water when you need to. Help your kidney.
