[0002] 手機在使用時，會散發大量電磁波，從而可能對人體健 康造成損害。因此，減少手機散發的電磁波，或者對電 磁波進行遮罩，一直是人們關心的問題。現有的防輻射 的技術很多，其中一種是在手機殼體上塗敷一電磁遮罩 層，反射手機發出的電磁波，使得穿過電磁遮罩層到達 人體的電磁波減少，從而達到防電遍輻射的目的。然而 ，電磁遮罩層反射的電磁波會對手¥射頻發射和择受電 路產生強干擾，從而影響手機的使用性能。 【發明内容】 [0003] 有鑒於此，提供一種防輻射手機殼體，其減少了電磁遮 罩對手機使用性能的影響。 [0004] 所述防輻射手機殼體，其包括殼體本體及附著於殼體本體 ，- 内表面上的防電磁波輻射的反射層，殼體本體内表面上 具有複數微型突起，使得所述反射層表面形成不平整表 面。 [0005] 由於殼體本體内壁上形成有多個微型突起，所述反射層 表面為不平整平面，因此手機發出的電磁波到達殼體後 會發生漫反射，從而大大降低單位面積内的反射電磁波 的強度，使其對手機射頻發射和接受電路產生的干擾被 降低，從而減少或消除了對手機使用性能的影響。 096124692 表單編號 A0101 第 3 頁/共 15 頁 0993267784-0 1332385 099年07月26日核正替換頁 【實施方式】 [0006] 請參考圖1，其揭示了本發明一最佳實施方式的防輻射手 機殼體10。該手機殼體10包括一前蓋20和一後蓋30。 [0007] 手機在使用時，前蓋20向著使用者，所以可以只在前蓋 20上設置防電磁輻射結構，使得手機内部電子元件發出 的電磁輻射不能達到使用者，從而達到防輻射的目的。 但也可同時在前蓋20和後蓋30上設置防電磁輻射結構。[0002] When a mobile phone is used, a large amount of electromagnetic waves are emitted, which may cause damage to human health. Therefore, reducing the electromagnetic waves emitted by mobile phones or masking electromagnetic waves has always been a concern. There are many existing radiation protection technologies, one of which is to apply an electromagnetic shielding layer on the mobile phone casing to reflect the electromagnetic waves emitted by the mobile phone, so that the electromagnetic waves passing through the electromagnetic shielding layer to the human body are reduced, thereby achieving the prevention of electric radiation. purpose. However, the electromagnetic waves reflected by the electromagnetic shielding layer will strongly interfere with the RF transmission and the selection circuit, which will affect the performance of the mobile phone. SUMMARY OF THE INVENTION [0003] In view of the above, an anti-radiation mobile phone case is provided that reduces the influence of electromagnetic shielding on the performance of a mobile phone. [0004] The radiation protection mobile phone case includes a housing body and a reflective layer attached to the inner surface of the housing body and protected from electromagnetic radiation, and the inner surface of the housing body has a plurality of micro protrusions, so that The surface of the reflective layer forms an uneven surface. [0005] Since a plurality of micro protrusions are formed on the inner wall of the casing body, the surface of the reflection layer is an uneven plane, so that electromagnetic waves emitted by the mobile phone reach diffuse reflection after reaching the casing, thereby greatly reducing reflected electromagnetic waves per unit area. The intensity, which causes the interference to the mobile phone's RF transmit and receive circuits to be reduced, reduces or eliminates the impact on handset performance. 096124692 Form No. A0101 Page 3 of 15 0993267784-0 1332385 07/26/2009 Nuclear Replacement Page [Embodiment] [0006] Please refer to FIG. 1, which discloses a radiation protection according to a preferred embodiment of the present invention. Mobile phone case 10. The handset housing 10 includes a front cover 20 and a rear cover 30. [0007] When the mobile phone is in use, the front cover 20 faces the user, so that the electromagnetic radiation-proof structure can be provided only on the front cover 20, so that the electromagnetic radiation emitted by the electronic components of the mobile phone cannot reach the user, thereby achieving the purpose of preventing radiation. However, it is also possible to provide an electromagnetic radiation prevention structure on the front cover 20 and the rear cover 30 at the same time.
[0008] 請參考圖2及圖3，前蓋20包括用於容納液晶螢幕的視窗 孔25、用於容納按鍵的鍵孔26。 [0009] 前蓋20包括一前蓋本體22、塗敷于前蓋本體22内表面上 的一層附著層23及塗敷於附著層23上的反射層24。 [0010] 前蓋本體22的材料可以是工程塑料，也可以是不銹鋼， 鎮銘合金，或其他材料。 [0011] 附著層23的材料為金屬氧化物，其作用是使反射層24更 好地附著于前蓋本體22上。在不同實施方式中也可以沒 有附著層23，亦不影響防輻射效果。但反射層24較難附 著于前蓋本體22上，使得製造較困難。反射層24的材料 為對電磁波反射效果好的金屬材料，如鋁、銅等。 [0012] 在前蓋本體22成型時，其内表面形成有多個微型突起21 ，這些微型突起21的分佈既可以是有規律的，如行列式 分佈，也可以是無規律岛。由於附著層23和反射層24較 薄（一般為零點幾毫米，為了清楚揭示手機殼體的結構 ，圖中所表示的附著層23和反射層24的厚度大於實際厚 度），附著于前蓋本體22上後並不會填平前蓋本體22的 096124692 表單編號 A0101 第 4 頁/共 15 頁 0993267784-0 1332385 099年07月26日核正替換頁 内表面，而是使得反射層24表面為不平整表面，其由複 數微小的、彼此鄰接和彼此傾斜的表面組成。 [0013] 參考圖4，該突起21為四棱錐形。Referring to FIGS. 2 and 3, the front cover 20 includes a window aperture 25 for receiving a liquid crystal screen, and a keyhole 26 for receiving a button. The front cover 20 includes a front cover body 22, an adhesive layer 23 applied to the inner surface of the front cover body 22, and a reflective layer 24 applied to the adhesive layer 23. [0010] The material of the front cover body 22 may be an engineering plastic, or may be stainless steel, Zhenming alloy, or other materials. [0011] The material of the adhesion layer 23 is a metal oxide, which serves to better adhere the reflective layer 24 to the front cover body 22. In some embodiments, the adhesion layer 23 may also be absent, and the radiation protection effect is not affected. However, the reflective layer 24 is more difficult to attach to the front cover body 22, making manufacturing more difficult. The material of the reflective layer 24 is a metal material having a good reflection effect on electromagnetic waves, such as aluminum or copper. [0012] When the front cover body 22 is formed, a plurality of micro protrusions 21 are formed on the inner surface thereof, and the distribution of the micro protrusions 21 may be regular, such as determinant distribution, or irregular islands. Since the adhesion layer 23 and the reflection layer 24 are relatively thin (generally a few tenths of a millimeter, in order to clearly reveal the structure of the mobile phone case, the thickness of the adhesion layer 23 and the reflection layer 24 shown in the figure is larger than the actual thickness), attached to the front cover After the body 22 is not filled, the 096124692 of the front cover body 22 is not filled. Form No. A0101 Page 4 of 15 0993267784-0 1332385 On July 26, 2008, the inner surface of the page is replaced, but the surface of the reflective layer 24 is An uneven surface consisting of a plurality of tiny surfaces that are adjacent to each other and inclined to each other. [0013] Referring to FIG. 4, the protrusion 21 is a quadrangular pyramid.
[0014] 參考圖5，當含有該防輻射手機殼體10的手機在使用時， 手機的電子元件（主要是包括天線40在内的射頻發射和 接受電路）發出大量的電磁波。由於在反射層24的表面 由複數微小的、彼此鄰接的和彼此傾斜的表面組成。電 磁波到達反射層2 4後發生漫反射，電磁波被反射到四面 八方，使得反射到手機的射頻發射和接受電路的電磁波 強度降低，其對射頻發射和接受電路的電磁干擾也因此 降低，從而達到減少或消除對手板使用性能的影響的目 的。 二 [0015] 參考圖6、圖7，突起21也可以為其他形狀，如三棱錐狀 、半球狀等。 【圖式簡單說明】Referring to FIG. 5, when the mobile phone containing the radiation protection handset case 10 is in use, the electronic components of the mobile phone (mainly the radio frequency transmitting and receiving circuits including the antenna 40) emit a large amount of electromagnetic waves. Since the surface of the reflective layer 24 is composed of a plurality of minute surfaces which are adjacent to each other and inclined to each other. After the electromagnetic wave reaches the reflective layer 24, diffuse reflection occurs, and the electromagnetic wave is reflected in all directions, so that the electromagnetic wave intensity of the radio frequency transmitting and receiving circuit reflected to the mobile phone is lowered, and the electromagnetic interference to the radio frequency transmitting and receiving circuit is also reduced, thereby achieving a reduction or Eliminate the impact of the impact of the performance of the opponent board. [0015] Referring to FIGS. 6 and 7, the protrusions 21 may have other shapes such as a triangular pyramid shape, a hemispherical shape, or the like. [Simple description of the map]
