Abstract
This invention provides a protection device of a mobile phone-a screen front cover processing a metal layer and a front cover to a unified one to form a screen front cover which blocks electric magnetic wave radiation to human body due to the screen of the metal layer to prevent mobile phone antenna from generating magnetic radiation to user brains on the premise of not influencing its function and talk quality and improve its safety usage performance.
Description
The present invention relates to a kind of protective device of mobile phone, it is to prevent the shielding upturning lid of the electromagnetic radiation of mobile phone antenna generation to user's injury.
At present, known mobile phone antenna is the critical piece that transmits and receives electromagnetic riveting machine signal.During mobile phone work, launching electromagnetic wave around day alignment, towards the electromagnetic wave of user's cephalad direction radiation, except that little part was reflected by head, major part was absorbed by brain, and brain comes to harm in various degree.Britain biological electromagnetic field researcher professor Gao Xier thinks mobile phone as electromagnetic wave transmitter the most powerful outside the microwave oven, also is near the powerful electromagnetic wave source of human body vitals brain.Mobile phone antenna can sending and receiving the microwave of brute force, and the energy that is produced (towards cephalad direction) has 60% to be absorbed by cerebral tissue.Therefore the people of all frequent use mobile phones above 20 minutes should often go to hospital to carry out the brain scans inspection.In (Science and Technology Daily 98225) October calendar year 2001, the international cancer research organization under the World Health Organization proposes, and electromagnetic wave has carcinogenic possibility.International cancer research organization is divided into 3 grades of " carcinogenicity is arranged ", " possibility height " and " can be carcinogenic " electromagnetic wave is carcinogenic.From statistics, it is clearly that electromagnetic wave has carcinogenic possible evidence.The World Health Organization has now determined to reformulate standard, no matter and the carcinogenic possibility of electromagnetic wave has much, require national governments and power industry to take preventive measures since this month, comprise to the resident sufficient information being provided, safety, cheap anti electromagnetic wave countermeasure being provided and strengthening the research of health risk etc. for the common people.(Science and Technology Daily 01116)
The purpose of this invention is to provide a kind of mobile phone shielding upturning lid that has changed aerial position.(renovating hereinafter to be referred as shielding) it can protect the user not injured by electromagnetic radiation under the prerequisite that does not change mobile phone serviceability and speech quality.
The object of the present invention is achieved like this: in the plane of mobile phone or concave shaped are renovated (on), the metal screen layer (metal coating, the coating that comprise high conductivity) of high conductivity is set, also can adopt metal to make and renovate shell, form shielding and renovate.And antenna is arranged on the center of mobile phone, the shielding of making is thus renovated, and can stop the electromagnetic wave of mobile phone antenna to the brain radiation, has function of shielding.
The shielding mechanism that shielding is renovated is: when mobile phone is worked, shielding is renovated and is between human brain and the antenna, electromagnetic wave towards human brain one side's radiation, in shielding is renovated (on) layer on surface of metal produce reflection, eddy current magnetism and the former magnetic field cancellation of inducting in the other direction and in metal level, cause thermal losses and repeatedly reflect, reach the purpose of block electromagnetic wave direction human brain one side's radiation.Shielding is renovated to mobile phone manufacturer makes the environmental protection mobile phone patented technology support is provided.
Owing to adopt such scheme, have the mobile phone that shielding is renovated, under the prerequisite that does not influence function of use and speech quality, can protect the user not injured by electromagnetic radiation.
The invention will be further described below in conjunction with Figure of description 1,2.
Figure of description 1 is that schematic diagram is renovated in shielding
Among the figure: 1. 4. mobile phone antenna 5. mobile phones of mobile phone upturning lid 2. upturning lid plastic casings, 3. metal formings (plate)
In the example shown in the Figure of description 1, adopting thickness is the red copper metal forming (plate) (3) of 0.1 mm, compound or be arranged in the upturning lid (1) of mobile phone, (single screen mobile phone also can be compounded in the upturning lid plastic outer layer shell, or be compounded in renovate extexine), antenna (4) is placed the center of mobile phone.Its manufacture craft is: when manufacturing is renovated, red copper metal forming (plate) (3) with 0.1mm, integral body is carried out surface treatment, preferably silver-plated, place in the upturning lid (1) of mobile phone, the upturning lid (1) of mobile phone is become one with red copper metal forming (plate) (3), and the shielding of making is thus as shown in Figure 1 renovated.
Figure of description 2 is that the mobile phone concave barrier is renovated schematic diagram
Among the figure: 1. 4. mobile phone antenna 5. mobile phones of mobile phone spill upturning lid 2. upturning lid plastic casings, 3. metal formings (plate)
In the example shown in the Figure of description 2, with the upturning lid (1) of mobile phone Make concave shaped, employing thickness is that the red copper metal forming (plate) (3) of 0.1mm is compound In the spill upturning lid (1) of mobile phone (on), single screen mobile phone can be compound At extexine, antenna (4) is placed the center of mobile phone, it makes the worker The elaboration that skill is done with Figure of description 1. Because having adopted concave barrier renovates and becomes Moved the position of antenna, the anti-electromagnetic radiation better effects if.
Claims (4)
1. an antenna is positioned at the mobile phone shielding upturning lid of center, it is characterized in that: in the renovating of mobile phone (on), be provided with metal screen layer.
2. metal screen layer according to claim 1 is characterized in that: metal screen layer adopts high conductivity metal paper tinsel (plate) to make.
3. metal screen layer according to claim 1 is characterized in that: metal screen layer adopts coating high conductivity metal technology to make.
4. metal screen layer according to claim 1 is characterized in that: metal screen layer adopts high conductivity metal to make the upturning lid shell.
