Therefore, need provide a kind of mobile phone, to solve the problem that improves mobile phone HAC performance in the prior art by the far field performance indexes that reduces mobile phone.
Summary of the invention
The technical problem that the present invention mainly solves provides a kind of mobile phone, and it has good HAC performance, can not reduce the far field performance indexes of mobile phone simultaneously.
For solving the problems of the technologies described above, the technical scheme that the present invention adopts is: a kind of mobile phone is provided, and it comprises shell, circuit board, antenna and sheet metal, and circuit board is arranged in the shell, antenna is arranged on the circuit board, sheet metal and unsettled be arranged on shell on corresponding with antenna.
According to one preferred embodiment of the present invention, sheet metal comprises first and second portion, and wherein first is positioned at the area just above of antenna, and second portion is positioned at outside the area just above of antenna.
According to one preferred embodiment of the present invention, the subregion of the area just above of first's cover antenna.
According to one preferred embodiment of the present invention, the area of second portion is greater than the area of first.
According to one preferred embodiment of the present invention, first and second portion are respectively rectangle, and on the direction of the line of demarcation of first and second portion, the width of first is less than the width of second portion.
According to one preferred embodiment of the present invention, the area of first is 5 * 8mm
2
According to one preferred embodiment of the present invention, sheet metal is a rectangle, and the area of sheet metal is 7 * 13mm
2
According to one preferred embodiment of the present invention, sheet metal attaches and is arranged on the outer surface parallel with circuit board of shell.
According to one preferred embodiment of the present invention, the phonate hole of outer surface and mobile phone is oppositely arranged.
The invention has the beneficial effects as follows: the situation that is different from prior art, mobile phone of the present invention is and unsettled be arranged on shell on corresponding with antenna by sheet metal, and then the minimizing mobile phone is to the Electromagnetic Interference of hearing aids, make mobile phone have good HAC performance, can not reduce the far field performance indexes of mobile phone simultaneously.

Fig. 2 is the schematic diagram according to the assembled state of the mobile phone of first embodiment of the invention; And
Fig. 3 is the schematic diagram according to the sheet metal in the mobile phone of second embodiment of the invention.
Embodiment
See also Fig. 1, Fig. 1 is the schematic diagram according to the decomposing state of the mobile phone of first embodiment of the invention.As shown in Figure 1, mobile phone 10 of the present invention comprises: shell 11,15, circuit board 12, antenna 13 and sheet metal 14.Circuit board 12 is arranged in the shell 11,15, and antenna 13 is arranged on the circuit board 12.
In the present embodiment, on the outer surface parallel with circuit board 12 that sheet metal 14 and antenna 13 be corresponding and unsettled to be arranged at shell 11, the phonate hole 151 that is arranged on the shell 15 of this outer surface and mobile phone 10 is oppositely arranged.This sheet metal 14 comprises first 141 and second portion 142.And as shown in Figure 2, first 141 is positioned at the area just above of antenna 13, and second portion 142 is positioned at outside the area just above of antenna 13.In the present embodiment, first 141 and second portion 142 are rectangle, between first 141 and the second portion 142 line of demarcation 143 is arranged, and on the direction in first 141 and the line of demarcation 143 of second portion 142, the width of first 141 is less than the width of second portion 142.
In a preferred embodiment, the area of first 141 is less than the area of second portion 142, and the area of first 141 is 5 * 8mm
2, the area of second portion 142 and shape all can change.
In use, when the electromagnetic field in mobile phone 10 near fields changes, the sheet metal 14 corresponding induced currents that change, this induced current makes sheet metal 14 produce the electromagnetic field of respective change, the electromagnetic field that sheet metal 14 inductions produce can play the effect of cancelling each other to the near field electromagnetic field that mobile phone 10 self produces, and then the electromagnetic interference of reduction mobile phone 10, the HAC performance of raising mobile phone 10, the while can not influence the far field performance indexes of mobile phone 10.In sheet metal 14, the improvement of 141 pairs of HAC performances of first plays a key effect, and can finely tune the HAC performance of mobile phone 10 by the area and the shape that change second portion 142.In the present embodiment, first 141 is arranged to the only subregion of the area just above of cover antenna 13, simultaneously the area of first 141 is arranged to can further guarantee less than the area of second portion 142 far field performance indexes of mobile phone 10.
See also Fig. 3, Fig. 3 is the schematic diagram according to the sheet metal in the mobile phone of second embodiment of the invention.As shown in Figure 3, the difference of the mobile phone 10 of the mobile phone of second embodiment and first embodiment is: sheet metal 24 integral body are rectangle, promptly on the direction in first 241 and the line of demarcation 243 of second portion 242, the width of first 241 equals the width of second portion 142.In a preferred embodiment, the area of sheet metal 24 is 7 * 13mm
