Abstract
The utility model relates to an electromagnetic waves protective sleeve for mobile telephones. Based on an ordinary sleeve for mobile telephones, the part corresponding to the obverse face of the mobile telephone of the ordinary sleeve for mobile telephones is prolonged to make the top end of the ordinary sleeve for mobile telephones align with the top end of mobile telephone antenna which is not pulled out, the inner of a prolonged part is clamped with a shielding absorbing layer such as shielding cloth containing metal fiber, a metal net, metal foil material or metal plates which are coated on a protective layer, and the outer side of the shielding absorbing layer is provided with a protective layer which is made of material which is same with the material of the outer sleeve of the utility model, such as leather, leatherette or other textiles. The utility model can be used as the ordinary sleeve for mobile telephones and can achieve the purpose of reducing the harm caused by electromagnetic waves to the human body.
Description
The utility model relates to a kind of mobile phone electromagnetic wave proof cover, belongs to a kind of mobile phone safety device.
The electromagnetic wave of being launched when existing mobile phone uses, can work the mischief to health,, but how use simple method by more and more many user's understanding, under the prerequisite that does not influence speech quality, reduce harmful electromagenetic wave radiation as far as possible, become problem anxious to be solved.
The utility model provides a kind of mobile phone electromagnetic wave proof cover, prevents the infringement of electromagnetic wave to human body effectively.
The purpose of this utility model is achieved in that this mobile phone electromagnetic wave proof cover is made of one bag of shape mobile phone cover; common machine at mobile phone puts; the part in its corresponding mobile phone front is upwards prolonged; aerial head before its top and telephone antenna are not pulled out is concordant; accompany the shielding absorbed layer in its prolongation inside, as shielding cloth, wire netting, the metal foil of metal fiber or be sprayed at the sheet metal of protective layer.And the shielding absorbed layer outside is provided with protective layer, and this protective layer constitutes as leather, artificial leather or other fabric then by the material consistent with overcoat.
The utility model advantage: when using owing to mobile phone, the electromagnetic wave major part that mobile phone is launched just in time aligns the prolongation in the utility model protective jacket, can reach the purpose of protection electromagnetic wave infringement fully; The electromagnetic wave of measuring brain one side (being the mobile phone front) according to China National Measuring Science Research Inst. reduces more than 50%.And (being the mobile phone back side) electromagnetic wave changes little in the other direction; Some place also slightly strengthens, and this shows that having reached the minimizing unwanted electromagnetic wave endangers the effect that does not influence the normal talking quality again.In addition, the utility model also can be used as the plain old telephone mantle and uses, one-object-many-purposes, use value height.
The utility model concrete structure is provided by following examples and accompanying drawing thereof:
Fig. 1: for the utility model master looks schematic diagram Fig. 2: for looking schematic diagram Fig. 3 in the left side of Fig. 1: be A-A profile Fig. 4 of Fig. 2: be the utility model user mode figure
Describe in detail below in conjunction with accompanying drawing:
This mobile phone electromagnetic wave proof cover is on common mobile phone mantle 1 part in its corresponding mobile phone front upwards to be prolonged; aerial head before its top and telephone antenna are not pulled out is concordant; accompany shielding absorbed layer 3 in its prolongation inside, as shielding cloth, wire netting, the metal foil of metal fiber or be sprayed at the sheet metal of protective layer.Be the shielding cloth of metal fiber in the present embodiment, at the protective layer 4,5 of the shielding cloth outside of metal fiber for being made of leather, other place's material of this protective layer and protective jacket is consistent.2 is common mobile phone mantle hyaline membrane among Fig. 1, and purpose is for seeing its keyboard and display clearly.6 is mobile phone body and antenna among Fig. 4, and 7 is penetrable sound hole among Fig. 1.
