Why Safeland Radiation free headphone do resist EMF and RF radiation?

 

 

 

1. Analysis on the superb structure design

 

with 250mm-400mm air tube, the ear buds were kept far away from the loudspeaker. Compared with the traditional headphoone whose speaker was fitted right inside the ear buds, Safeland radiation free headphone boasts of the advantage of the insulation of magnetic field and radiation source thanks to the air tube design. As for the traditional headphone, the radiation source of mobile phone is absorbed directly into brain through wire. Besides, 1000Gs permanent magnetic field of the speaker inside the traditional headphone is harmful to brain. Moreover, alternating magnetic field produced by interactive effect between coils, audio current and permanent magnet has a negative influence on eardrums. Meanwhile, high frequency vibration of coil and acoustic membrane caused by electromotive force is seriously harmful to brain.

 

 

 

2. Analysis on the physical theory

 

The electromagetic radiation is inversely proportional to the square of distance. Safeland radiation resistant headphone is connected by air tube and wire of a certain length. Therefore, mobile phone is kept a distance from human body in case of proper operation of the function button to answer and end a call. As a result, radiation magnetic field is lowed to the Hygienic standard for environmental electromagnetic waves GB9175-88(S<10uw/cm²)issued by healthy organization.

 

 

 

3. Analysis on the using method

 

Safeland radiation free headphone can keep a long distance between the mobile phone and the human body when using the function key to dial and end a call, which effectively avoid serious radiation during the incoming and calling status. Many mobile phones take the traditional headphones as antennas, while Safeland radiation free headphone takes advantage of the air tube to avoid the direct radiation from antenna.
