FC CHANGJIANG RADIATION-PROOF EARPHONES ARE TERMINAL CHOICES OF NEW GENERATION MOBILE PHONES
The new generation of mobile phones terminal can not go without earphone,as we need both read pictures and listen to music and watch video when we spend more time on mobile phones.More and more people have realized the harm that the radiation of mobile phones can cause,so FC Changjiang radiation-proof earphones are our best solution to them.
Product models(FC01)
Specification:All technical parameter can meet national standards
Figuration drawing:
Advantage:
1. Gain Germany patent,China invention patent and PCT certificate.
2. Passed CE,FCC,ROHS Certificate.
WHY DO WE PRODUCE THE RADIATION-PROOF EARPHONES?
Now that your company is so large,and car industy,at this moment,is in so favorable situation,why do you still want to engage in production of radiation-proof earphones?
Nowadays,more people suffer from mobile phones radiation,On May 26,2009,Le Figaro in France reported that a suggestion was made by its ministers,environmental association,mobile phone users,and representatives from national and local groups,that a mobile phone should be limited to SMS,when people's health is taked into consideration.
They also proposed that mobile phones should be equipped with earphones.On Oct 8,2009,Le Figaro has another report,saying that students of primary and secondary schools in UK.USA,South Korea and Japan are forbidden to use a mobile phone.And developing countries,like Russia,also concern with mobile phone radiation,By this token,forbidding students,using mobile phone has become a trend the world over,Among other things,radiation from mobile phones proved harmful people,s health ,including adults,more use of mobile phones,more adverse effect,because radiation can be accumulated in human body,Many more events of people being harmed by mobile phone radiation can be read on internet. and in periodicals as well.
Changjiang Company wants to prevent us and our next generation from being harmed by radiation from mobile phone,and for the health of human being,and make more contribution to society.

THE RADIATION-PROOF THEORY OF FC CHANGJIANG EARPHONES
HOW MOBILE PHONE RADIATION AFFECT OUR BODY?
Mobile phones produce radiation during the exchange of radio signals any time.The radiation is stronger when talking through mobile phones.So phone is the source of radiation itself.We found through experiments that surface-mount technology can not reduce radiation:We put a mobile phone into iron box with its door 5mm open and its earphones out of the box.It still can work well,It proves that phones can receive and spend singals normally .Screening will not reduce radiation because phone can not work after it.To absorb radiation will affect phone,normal exchange of signals.So the only way to reduce radiation is to keep certain distance between mobile phones and us.FC Changjiang radiation-proof earphones are the best solution to this problem.
TYPICAL STRUCTURE OF RADIATION-PROOF EARPHONES
Ear plugs of FC Changjinag radiation-proof earphones are far away from lound speakers with 250-400mm acoustic lines to separate lound speaker magnectism and radiation source.Common earphones,loud speakers are in earplugs.Radiation through conductor will be absorted by brain;1000Gs permanent magnet in ear plugs is harmful for our brain Alternating magnetic field produced by tune currents of wire coils and permanent magnet affect our ear nerve and eardrum;Vibration caused by the electromotance loudspeaker and voice membrane will damage our eardrums too.Flux by two magnetic field harm greatly our brain when two earplugs in both of ears.
PHYSICAL THEORY
The attenuation specification of electronmagnetic wave is inversely proportional to distance.Ear plugs of FC Changjiang radiation-proof earphones are connected with phones by an anti electronmagnetic wave acoustic channel.Operating phone calls by switches in earphones is keep us a certain distance from phones.We can produce radiation magneticfield to under 2MG which has no harm to human body.
TYPICAL USING METHOD
Operating phone calls by switch board in earphones is to keep us a certain distance from phones.Earphones of some mobile phones are also their antenna.FC Changjiang earphones have acoustic line which is to avoid direct radiation.
