Headset is according to their drive (transducer) and the type of it to wear to the classification of the way.
Moving coil type
Moving coil in-ear headphones are the most common, the most common headphones, it’s drive unit is basically a small moving coil speakers, the permanent magnetic field in the voice coil of driving and connected to the diaphragm of the vibration. Moving coil headphones for high efficiency, mostly on the headset for the output driver and reliable and durable.
Magnetic type such as
The driver of the magnetic headphones, similar to narrow the plane of the speaker, and it will be embedded in the plane of the voice coil frivolous diaphragm, like printed circuit board the same average distribution of the driving force. Magnets in the diaphragm of the focus on one or both (push-pull), diaphragm in the formation of the magnetic field vibration. Magnets diaphragm no headphones and electrostatic headset diaphragm that light, but there are also big vibration area and similar sound quality, it as moving coil headphones for high efficiency, and it is not easy to drive.
Electrostatic type
Electrostatic headphones have light and thin film vibration, the high voltage dc polarization, polarization the electricity required by ac conversion, also has a battery power supply. Diaphragm hanging on by two fixed metal plate (stator) to form the electrostatic field, when the audio signal to load the stator, electrostatic field changes, the driver diaphragm vibration. Single stator is also can drive the diaphragm, but double the stator the push-pull form less distortion. Electrostatic headset must use special amplifier will audio signals are converted to hundreds of v voltage signal and use transformer connected to the power amplifier output terminal of the electrostatic headset can also drive. Electrostatic headset expensive, not easy to drive, the reach of level is also not moving coil in-ear headphones, but its response speed and could put all sorts of tiny details of heavy, very low distortion.
In a body
In a body headphones also called fixed electrostatic headphones, it’s diaphragm is itself or by the diaphragm of the polarization of the launch of the polarization material static electric field polarization, does not need special equipment with polarization voltage. In a body of static headset most of the headset features, but in very experience gradually to polarization, need to change, its life about 5 to 10 years.
Wireless headset and cordless headset
They consist of two parts, signal emitter and with receiving signal and amplification device headset (usually moving coil type). Transmitters and signal source is linked together, also can be in the former stage before the transmitter access or headphone amplifiers to improve quality and adjust the tone.
Wireless headset generally refers to the infrared transmission signal headset system, cordless headset is refers to using radio waves of transmitting signals headset system. The working frequency of infrared headset from several KHz to a few MHz, effective distance about 10 meters, headphones to the visible range; Radio headset working frequency VHF 130 MHz to 200 MHz, UHF 450 MHz to 900 MHz, most cordless headphones work in UHF, but transmission range of 100 meters, can around obstructions. Two vice or more wireless/cordless headset deputy may be disturbed each other, so choose when they had better choose to have DuoGe work of the frequency of varieties, for cordless headphones, working in UHF than in the interference on VHF may be small. The two kinds of background noise headphones are, more high-grade models have adopted the technology reduces the noise. Also note that the wireless/cordless headset battery life, generally should not be less than 8 hours.

Everyone -

Regarding “Card-Check” – and I say this as a former Union Committeeman, Pray Tell – why do we see the institution of Secret Ballot Union Representational Elections as a reform IN MEXICO – and an Impediment in the USA?

I wish for Jesus to pop out of those clouds and scare those evil people to death.

This is a good wish list, as are the additions to it. My wish is for good health for everyone, as I am battling several chronic illnesses that will eventually kill me – maybe I should wish to be healed – don’t know about that one, it sounds selfish.

The only other thing I would wish for, is for politicians to be required to resign their position in government – i.e. senators, congressmen and women, governors – prior to running for another office. This last presidential race lasted almost two years. I think it’s rediculous to be paid for a job that you’re not performing. I don’t care whether it’s a Republican or a Democrat, you want to run for a certain office, take a chance, but don’t expect to be paid for running for office.

Thinking Person thanks for your remarks. I did not vote for Obama. Actually,
we probably agree more than we disagree. I have never worked for an auto
company but retired from a large health insurance company. The huge healthcare packages you mention do not exist. The huge retirement packages
don’t exist except possibily at the executive level. Retirement is supplemented by paying into a 401k. Which is now in the tank.
David Thompson-if only the the economy could be solved as easily as turning around an apartment complex.
I listened to the hearing today on Freddie and Frannie. The economist are
projecting 8 million more mortgage foreclosures. Those who have a car may be
living in it.
I do think I prefer someone “work” for their govenment money, instead of
staying home and having it mailed to them.

“The employees from these companies plus part suppliers and
vendors will be collecting taxpayer funds when they have no job.”

I agree completely with the above comments of Jim Baker. Somebody is still going to build and sell cars. Some people may indeed lose their jobs—but others will be hired. The net loss may be next to zilch, and there could even be an increase in hiring. These three companies should go bankrupt so that these matters can be sorted out. A bailout only delays the inevitable and makes the ultimate resolution that much more difficult.

I once lived next door to a large apartment complex that went bankrupt. The buyers paid about ten cents on the dollar for the remaining assets. They turned the property into a thriving community! This, by the way, is often the result of bankruptcy. The process must be endured. It simply cannot be avoided.

G-Ma….I think you can rest assured that if the big 3 bailout doesn’t go through now, it surely will after Obama’s anointing in January. I am vehemently against it though. The automakers should have to reorganize which they will NEVER do if bailed out now and again next year and over and over and over. Bad decisions were made at the top, the company was bent over by the union bosses and unfortunately for you apparently the unsuspecting workers were at their mercy. I feel bad for you and others who will lose their jobs in all of this turmoil truly but there are so many others out in this great country of ours without HUGE retirement packages and HUGE healthcare packages that will also lose their jobs with no hope of a bailout. Sometimes it is truly a bitter pill but I don’t think you should worry. The unions have dear leader Obama’s you-know-whats in a vice and he’ll come through for them and you. It’s the rest of us tax-payers that will then need to be bailed out. Will Obama do the same for us then? Will you feel for us too G-Ma?

The cars and trucks still have to get built, whether it is the UAW/GM or the Japanese. Jobs will be there, just relocated to more competitive plants. If the UAW/GM can’t build the same quality car for the same cost, how do they compete? Currently, it costs UAW/GM about $2000 more to pay for labor on the building of one car. ( Average wages for UAW/GM workers is about $150,000/year. Average wages for Toyota plants in the USA is about $100,000/year. $50,000/year times 200,000 UAW/GM workers is $10 billion/year. ) Time for UAW/GM to get real. I think an auto worker can make it on $100,000. If UAW/GM decide to become competitive, very few jobs would be lost. Competitively speaking, this labor union has destroyed GM, and with full co-operation from GM. When a company no longer cares what it’s labor costs are, it will be like what they said after they cut the tail off the proverbial monkey.
