Abstract
The cellphone includes at least one liquid crystal display; one printed circuit board with RF shielding unit and one fundamental frequency circuit and connected to the liquid crystal display; one keyboard connected to the printed circuit board; and one cell set between the keyboard and the printed circuit board. The present invention features that the cell, the RF shielding unit, the fundamental frequency circuit, the liquid crystal display and other elements are set on the same side of the printed circuit board with electromagnetic wave emitting source, and this increases the distance between the printed circuit board and human body, reduces the effect of cellphone electromagnetic wave to human body and improves the structure strength of the cellphone.
Description
(1) technical field
The relevant a kind of mobile phone of the present invention.
(2) background technology
Because popularizing of the progress of wireless telecommunications science and technology and mobile phone, mobile phone has become people's indispensable instrument in life, yet uses frequent day by day today at mobile phone, and people also are alerted to the electromagnetic wave that should avoid mobile phone to send human body is produced harmful effect.According to the PLMN01 of General Administration of Telecommunications standard, the organism unit mass is the important indicator of a measurement electromagnetic wave to the organism influence degree to electromagnetic wave energy specific absorption rate (SAR, Specific Absorption Rate) value; Yet human body occurs in when using mobile phone especially easily for absorbing electromagnetic effect, and this is that the hypotelorism of user's head and mobile phone causes because when using mobile phone.
At the method that reduces mobile phone electromagnetic wave, known techniques is many to hinder electromagnetic transmission to add shielding or barrier element, yet so not only can thereby destroy outside the former design, and need bear extra purchase cost, so do not have an economic benefit because of the weight that increases mobile phone itself.Again because general mobile phone electromagnetic wave generation source is usually located at the printed circuit board (PCB) place, this is to have due to antenna connects because of this place, be inversely proportional to according to electromagnetic intensity in the known theory and distance again, so motivation of the present invention is to improve the structure of known mobile phone, increase the distance between printed circuit board (PCB) and human body, reduce the purpose of mobile phone electromagnetic wave the human influence to reach.
At the handset configuration of commonly using, see also Fig. 1 and Fig. 2.Wherein, as shown in Figure 1, keyboard 2 is to be arranged on the printed circuit board (PCB) 3 and with upper shell cover 1 to engage.3 of printed circuit board (PCB)s are connected with LCD (LCD) 31 by pliable printed circuit 32, opposite side at printed circuit board (PCB) 3 disposes radio-frequency shielding fence (RF Shielding) 33 and baseband circuit 34, battery 5 then is arranged at this baseband circuit 34 belows, and can engage battery limitation with lower cover 4 and be fixed in the mobile phone body by battery cover 6, be bonded into assembled state by upper shell cover 1 and lower cover 4 at last.
As the above-mentioned mobile phone of commonly using, it is when assembled state, this printed circuit board (PCB) to the distance on body top surface is equivalent to the thickness that keyboard 2 only or LCD 31 are added upper shell cover 1, be quite near (as shown in Figure 2), so if can change known structure, employing is arranged at the configuration mode of below with all the other elements (as radio-frequency shielding fence, baseband circuit, battery), can improve the problem of printed circuit board (PCB) and human body hypotelorism.In addition,, cover, thereby make the structural strength variation of mobile phone integral body in order to loading and unloading battery and setting battery because lower cover must carry out holes or cutting.
(3) summary of the invention
The purpose of this invention is to provide a kind of reduce the organism unit mass to electromagnetic wave energy specific absorption rate (SAR) value and can be safer in use going up, mobile phone that structural strength is better.
For further specifying purpose of the present invention, design feature and effect, the present invention is described in detail below with reference to accompanying drawing.
(4) description of drawings
Fig. 1 is the three-dimensional exploded view of known mobile phone;
Fig. 2 shows the vertical cut-away schematic view of known mobile phone;
Fig. 3 is a three-dimensional exploded view of the present invention;
Fig. 4 shows vertical cut-away schematic view of the present invention.
(5) embodiment
See also Fig. 3 and Fig. 4, wherein Fig. 3 is the three-dimensional exploded view of preferred embodiment of the present invention, and Fig. 4 is the vertical cut-away schematic view of expression preferred embodiment of the present invention.
As shown in Figure 3, handset configuration of the present invention comprises: elements such as upper shell cover 9, keyboard 7, battery 8, printed circuit board (PCB) 10 and LCD 101.Wherein, upper shell cover 9 has depressed part 91 and perforate 92; And battery 8 is arranged between this keyboard 7 and this upper shell cover 9, and battery 8 all is arranged in the depressed part 91 of upper shell cover 9 with keyboard 7.In printed circuit board (PCB) 10, also include: radio-frequency shielding fence 103 and baseband circuit 104, wherein radio-frequency shielding fence 103 is disposed on the printed circuit board (PCB) 10 with baseband circuit 104.LCD 101 is to be electrically connected to each other by pliable printed circuit 102 and printed circuit board (PCB) 10; Keyboard 7 then is to pass perforate 92 by pliable printed circuit 71 to electrically connect with printed circuit board (PCB) 10; At last engage the assembled state of finishing mobile phone with upper shell cover 9 by lower cover 11.
Characteristics of the present invention are: battery 8, radio-frequency shielding fence 103, baseband circuit 104 and LCD 101 all are positioned at the top of printed circuit board (PCB) 10, that is are positioned at the same side of printed circuit board (PCB) 10 with keyboard 7.Like this, in mobile phone of the present invention, the position of printed circuit board (PCB) 10 can directly be attached on the lower cover 11, remaining inner member then places this same side, printed circuit board (PCB) 10 top, therefore can make and form the bigger distance of more known mobile phone between printed circuit board (PCB) (electromagnetic wave generation source) and the human body by the configuration of this inner member.
Other sees also Fig. 4, be different from known mobile phone (as shown in Figure 2), the present invention is in the distance of printed circuit board (PCB) 10 and keyboard 7, between be separated with radio-frequency shielding fence 103, baseband circuit 104 and battery 8, and the configuration mode (keyboard 2 directly is arranged on the printed circuit board (PCB) 3) of the known mobile phone in Fig. 2, the present invention can effectively increase the distance between this printed circuit board (PCB) and human body under the situation of the size that does not increase mobile phone integral body, and then reduces the influence of mobile phone electromagnetic wave to human body.
In addition, because battery 8 is disposed between keyboard 7 and the printed circuit board (PCB) 10, and be positioned at the homonymy of printed circuit board (PCB) 10 with LCD 101, so lower cover 11 does not need in addition holes or cutting, so its structural strength has holes or the lower cover (4 among Fig. 1 and Fig. 2) that was cut for good.
At this structural improvement, it there is no different in outward appearance and function with general mobile phone, also must not install any accessory additional in the use and destroy original design, and the present invention really can promote the fail safe in the use of known handset configuration, lower the SAR value of mobile phone, real is that one of known mobile phone improves greatly.
Certainly, those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the present invention, and be not to be used as limitation of the invention, as long as in connotation scope of the present invention, all will drop in the scope of claims of the present invention variation, the modification of the above embodiment.
