Description
本案是有關於一種電子裝置，且特別是有關於一種具有天線元件的電子裝置。 The present invention relates to an electronic device, and more particularly to an electronic device having an antenna element.
現今的電子裝置除了強調多功能外，更著重於裝置的外觀設計，以藉此吸引消費者的目光。例如利用金屬材質的殼體與銘牌，來增加電子裝置在外觀上的獨特性與現代感。然而，當電子裝置採用金屬殼體與金屬銘牌時，設置在金屬殼體之表面的近場通訊(Near Field Communication，簡稱NFC)天線往往會受到金屬之屏蔽效應(shielding effect)的影響，而導致近場通訊天線的通訊品質下降。 In addition to emphasizing versatility, today's electronic devices focus more on the design of the device to attract consumers' attention. For example, a metal casing and a nameplate are used to increase the uniqueness and modernity of the electronic device. However, when the electronic device uses a metal casing and a metal nameplate, Near Field Communication (NFC) antennas disposed on the surface of the metal casing are often affected by the shielding effect of the metal, resulting in The communication quality of the near field communication antenna is degraded.
本案提供一種電子裝置，其利用絕緣結構導引出第二環形電流，並利用第二環形電流來提升第二天線元件的通訊品質增，並藉此降低導電元件與傳導材質殼體對第二天線元件所造成的影響。 The present invention provides an electronic device that utilizes an insulating structure to guide a second annular current and utilizes a second annular current to increase communication quality of the second antenna element, thereby reducing the conductive element and the conductive material housing pair second The effect of the antenna elements.
本案的電子裝置，包括傳導材質殼體、第一天線元件、第二天線元件以及絕緣結構。第一天線元件設置在傳導材質殼體內。第二天線元件設置在傳導材質殼體的外表面，並相對於第一天線元件。傳導材質殼體響應於第二天線元件的操作而產生第一環形電流。絕緣結構貫穿傳導材質殼體，並從傳導材質殼體的至少一側邊延伸至第二天線元件。傳導材質殼體更響應於第一天線元件的操作而產生一感應電流，且絕緣結構阻隔感應電流，以致使傳導材質殼體產生第二環形電流，其中第一環形電流與第二環形電流的電流方向相同。 The electronic device of the present invention comprises a conductive material housing, a first antenna element, a second antenna element and an insulating structure. The first antenna element is disposed within the conductive material housing. The second antenna element is disposed on an outer surface of the conductive material housing and opposite to the first antenna element. The conductive material housing generates a first annular current in response to operation of the second antenna element. The insulating structure extends through the conductive material housing and extends from at least one side of the conductive material housing to the second antenna element. The conductive material housing further generates an induced current in response to the operation of the first antenna element, and the insulating structure blocks the induced current to cause the conductive material housing to generate a second annular current, wherein the first annular current and the second annular current The current direction is the same.
基於上述，本案的絕緣結構貫穿傳導材質殼體，並從傳導材質殼體的至少一側邊延伸至第二天線元件。藉此，傳導材質殼體因應第一天線元件而產生的感應電流會在絕緣結構的阻隔下，而轉變成與第一環形電流同方向的第二環形電流。此外，第二環形電流將有助於增加第二天線元件的磁通量，進而降低導電元件與傳導材質殼體對第二天線元件所造成的影響。 Based on the above, the insulating structure of the present case extends through the conductive material housing and extends from at least one side of the conductive material housing to the second antenna element. Thereby, the induced current generated by the conductive material casing in response to the first antenna element is converted into a second annular current in the same direction as the first annular current under the barrier of the insulating structure. In addition, the second annular current will help increase the magnetic flux of the second antenna element, thereby reducing the effect of the conductive element and the conductive material housing on the second antenna element.
為讓本案的上述特徵和優點能更明顯易懂，下文特舉實施例，並配合所附圖式作詳細說明如下。 In order to make the above features and advantages of the present invention more comprehensible, the following embodiments are described in detail with reference to the accompanying drawings.

圖1為依據本案一實施例之電子裝置的結構示意圖。參照圖1，電子裝置100包括傳導材質殼體110、第一天線元件120、第二天線元件130、絕緣結構140與導電元件150。 1 is a schematic structural view of an electronic device according to an embodiment of the present invention. Referring to FIG. 1 , the electronic device 100 includes a conductive material housing 110 , a first antenna element 120 , a second antenna element 130 , an insulating structure 140 , and a conductive element 150 .
第一天線元件120設置在傳導材質殼體110內。例如，傳導材質殼體110具有一容置空間，且第一天線元件120設置在所述容置空間內。此外，第一天線元件120可例如是一線圈式天線(coil antenna)，並會接收來自電子裝置100中一收發模組(未繪示出)的饋入訊號。藉此，在饋入訊號的激發下，第一天線元件120(例如，線圈式天線)將可產生一交變磁場。 The first antenna element 120 is disposed within the conductive material housing 110. For example, the conductive material housing 110 has an accommodating space, and the first antenna element 120 is disposed in the accommodating space. In addition, the first antenna element 120 can be, for example, a coil antenna and receive a feed signal from a transceiver module (not shown) in the electronic device 100. Thereby, the first antenna element 120 (eg, a coiled antenna) will generate an alternating magnetic field upon excitation of the feed signal.
第二天線元件130設置在傳導材質殼體110的外表面，且第二天線元件130與傳導材質殼體110的外表面電性絕緣。例如，第二天線元件130與傳導材質殼體110之間設有一絕緣層。此外，第二天線元件130隔著傳導材質殼體110相對於第一天線元件120，且第二天線元件130鄰近絕緣結構140。在操作上，第二天線元件130相當於一近場通訊天線，並用以導引第一天線元件120所產生的交變磁場。藉此，電子裝置100將可透過空間中的交變磁場來傳送訊息。相對地，傳導材質殼體110會響應於第二天線元件130的操作而產生第一環形電流。 The second antenna element 130 is disposed on an outer surface of the conductive material housing 110, and the second antenna element 130 is electrically insulated from an outer surface of the conductive material housing 110. For example, an insulating layer is disposed between the second antenna element 130 and the conductive material housing 110. In addition, the second antenna element 130 is opposite to the first antenna element 120 via the conductive material housing 110 , and the second antenna element 130 is adjacent to the insulating structure 140 . In operation, the second antenna element 130 is equivalent to a near field communication antenna and is used to guide the alternating magnetic field generated by the first antenna element 120. Thereby, the electronic device 100 transmits the message through the alternating magnetic field in the space. In contrast, the conductive material housing 110 generates a first annular current in response to operation of the second antenna element 130.
絕緣結構140貫穿傳導材質殼體110，並從傳導材質殼體110的至少一側邊延伸至第二天線元件130。例如，傳導材質殼體110的至少一側邊包括第一側邊SD11與第一側邊SD12，且第一側邊SD11相對於第二側邊SD12。此外，絕緣結構140分別從第一側邊SD11與第二側邊SD12延伸至第二天線元件130，且絕緣結構140與傳導材質殼體110的第一側邊SD11與第一側邊SD12相交。亦即，絕緣結構140分別截斷傳導材質殼體110的第一側邊SD11與第一側邊SD12。 The insulating structure 140 extends through the conductive material housing 110 and extends from at least one side of the conductive material housing 110 to the second antenna element 130. For example, at least one side of the conductive material housing 110 includes a first side SD11 and a first side SD12, and the first side SD11 is opposite to the second side SD12. In addition, the insulating structure 140 extends from the first side SD11 and the second side SD12 to the second antenna element 130, respectively, and the first side SD11 of the insulating structure 140 and the conductive material housing 110 intersects with the first side SD12. . That is, the insulating structure 140 cuts off the first side SD11 and the first side SD12 of the conductive material housing 110, respectively.
更進一步來看，在圖1實施例中，絕緣結構140的形狀可例如是T形，且絕緣結構140包括第一絕緣線141與第二絕緣線142。在整體配置上，第一絕緣線141從第一側邊SD11延伸至第二側邊SD12，並相交於第一側邊SD11與第二側邊SD12。第二絕緣線142與第一絕緣線141相互垂直。此外，第二絕緣線142的第一端連接第一絕緣線141，且第二絕緣線142的第二端鄰近第二天線元件130。 Furthermore, in the embodiment of FIG. 1, the shape of the insulating structure 140 may be, for example, a T shape, and the insulating structure 140 includes a first insulated wire 141 and a second insulated wire 142. In an overall configuration, the first insulated wire 141 extends from the first side SD11 to the second side SD12 and intersects the first side SD11 and the second side SD12. The second insulated wire 142 and the first insulated wire 141 are perpendicular to each other. In addition, the first end of the second insulated wire 142 is connected to the first insulated wire 141, and the second end of the second insulated wire 142 is adjacent to the second antenna element 130.
值得注意的是，第一天線元件120所產生的交變磁場也會致使傳導材質殼體110感應出一感應電流。換言之，傳導材質殼體110也響應於第一天線元件110的操作而產生一感應電流。此外，貫穿傳導材質殼體110的絕緣結構140會阻隔傳導材質殼體110所感應出的感應電流，進而致使傳導材質殼體110產生第二環形電流。其中，第一環形電流與第二環形電流的電流方向相同。 It should be noted that the alternating magnetic field generated by the first antenna element 120 also causes the conductive material housing 110 to induce an induced current. In other words, the conductive material housing 110 also generates an induced current in response to operation of the first antenna element 110. In addition, the insulating structure 140 extending through the conductive material housing 110 blocks the induced current induced by the conductive material housing 110, thereby causing the conductive material housing 110 to generate a second annular current. Wherein, the first annular current is the same as the current direction of the second annular current.
舉例來說，圖2為圖1之電子裝置的部分結構示意圖。如圖2所示，傳導材質殼體110會因應第一天線元件120的交變磁場而感應出一感應電流210。此外，感應電流210會在絕緣結構140的阻隔下，而導引出第二環形電流220。另一方面，傳導材質殼體110也會響應於第二天線元件130的操作而產生第一環形電流230。值得注意的是，第二環形電流220與第一環形電流230的電流方向相同。因此，第二環形電流220將有助於增加第二天線元件130(亦即，近場通訊天線)的磁通量(magnetic flux)，進而提升第二天線元件130的通訊品質。 For example, FIG. 2 is a partial structural diagram of the electronic device of FIG. 1. As shown in FIG. 2, the conductive material housing 110 induces an induced current 210 in response to the alternating magnetic field of the first antenna element 120. In addition, the induced current 210 will conduct a second annular current 220 under the barrier of the insulating structure 140. On the other hand, the conductive material housing 110 also produces a first annular current 230 in response to operation of the second antenna element 130. It is worth noting that the second annular current 220 is in the same direction as the current of the first annular current 230. Therefore, the second annular current 220 will help increase the magnetic flux of the second antenna element 130 (i.e., the near field communication antenna), thereby improving the communication quality of the second antenna element 130.
此外，如圖1所示，導電元件150覆蓋在第二天線元件130上。其中，導電元件150與第二天線元件130電性絕緣。例如，導電元件150與第二天線元件130之間亦設有另一絕緣層。此外，導電元件150可例如是具有與產品相關的圖案或文字的一金屬銘牌。值得注意的是，第二環形電流可提升第二天線元件130的通訊品質，進而降低導電元件150與傳導材質殼體110之屏蔽效應對第二天線元件130所造成的影響。 Further, as shown in FIG. 1, the conductive member 150 is overlaid on the second antenna element 130. The conductive element 150 is electrically insulated from the second antenna element 130. For example, another insulating layer is also disposed between the conductive element 150 and the second antenna element 130. Additionally, conductive element 150 can be, for example, a metal nameplate having a pattern or text associated with the product. It should be noted that the second annular current can improve the communication quality of the second antenna element 130, thereby reducing the influence of the shielding effect of the conductive element 150 and the conductive material housing 110 on the second antenna element 130.
換言之，傳導材質殼體110因應第一天線元件120而產生的感應電流會在絕緣結構140的阻隔下，而轉變成與第一環形電流同方向的第二環形電流。如此一來，第二環形電流將有助於增加第二天線元件130(亦即，近場通訊天線)的磁通量，進而提升第二天線元件130的通訊品質，並藉此降低導電元件150與傳導材質殼體110對第二天線元件130所造成的影響。 In other words, the induced current generated by the conductive material housing 110 in response to the first antenna element 120 may be converted into a second annular current in the same direction as the first annular current under the barrier of the insulating structure 140. As such, the second annular current will help increase the magnetic flux of the second antenna element 130 (ie, the near field communication antenna), thereby improving the communication quality of the second antenna element 130, and thereby reducing the conductive element 150. The effect of the conductive material housing 110 on the second antenna element 130.
雖然圖1實施例列舉了絕緣結構140的實施型態，但其並非用以限定本案。舉例來說，圖3為依據本案另一實施例之電子裝置的結構示意圖。其中，圖3實施例所列舉的電子裝置300與圖1實施例所列舉的電子裝置100相似。此外，與圖1實施例主要不同之處在於，傳導材質殼體310的至少一側邊包括第一側邊SD31，且絕緣結構340的形狀為一字形。 Although the embodiment of FIG. 1 exemplifies the embodiment of the insulating structure 140, it is not intended to limit the present invention. For example, FIG. 3 is a schematic structural diagram of an electronic device according to another embodiment of the present disclosure. The electronic device 300 exemplified in the embodiment of FIG. 3 is similar to the electronic device 100 exemplified in the embodiment of FIG. 1. In addition, the main difference from the embodiment of FIG. 1 is that at least one side of the conductive material housing 310 includes a first side SD31, and the insulating structure 340 has a shape of a letter.
具體而言，絕緣結構340包括一絕緣線341。其中，絕緣線341垂直於第一側邊SD31。此外，絕緣線341的第一端與第一側邊SD31相交，且絕緣線341的第二端鄰近第二天線元件130。此外，圖4為圖3之電子裝置的部分結構示意圖。如圖4所示，傳導材質殼體310會響應於第二天線元件130的操作而產生第一環形電流230。此外，傳導材質殼體310也會因應第一天線元件120的交變磁場而感應出一感應電流210。 Specifically, the insulating structure 340 includes an insulated wire 341. The insulated wire 341 is perpendicular to the first side SD31. Further, the first end of the insulated wire 341 intersects the first side SD31, and the second end of the insulated wire 341 is adjacent to the second antenna element 130. In addition, FIG. 4 is a partial structural diagram of the electronic device of FIG. 3. As shown in FIG. 4, the conductive material housing 310 generates a first annular current 230 in response to operation of the second antenna element 130. In addition, the conductive material housing 310 also induces an induced current 210 in response to the alternating magnetic field of the first antenna element 120.
此外，感應電流210會在絕緣結構340的阻隔下，而轉變成與第一環形電流230同方向的第二環形電流220。藉此，第二環形電流220將有助於增加第二天線元件130的磁通量，進而降低導電元件150與傳導材質殼體310對第二天線元件130所造成的影響。至於圖3之其餘構件的詳細說明已包含在上述實施例中，故在此不予贅述。 In addition, the induced current 210 is converted to a second annular current 220 in the same direction as the first annular current 230 under the barrier of the insulating structure 340. Thereby, the second annular current 220 will help to increase the magnetic flux of the second antenna element 130, thereby reducing the influence of the conductive element 150 and the conductive material housing 310 on the second antenna element 130. The detailed description of the remaining components of FIG. 3 is included in the above embodiment, and thus will not be described herein.
綜上所述，本案的傳導材質殼體會響應於第二天線元件的操作而產生第一環形電流。此外，絕緣結構貫穿傳導材質殼體，並從傳導材質殼體的至少一側邊延伸至第二天線元件。藉此，傳 導材質殼體因應第一天線元件而產生的感應電流會在絕緣結構的阻隔下，而轉變成與第一環形電流同方向的第二環形電流。第二環形電流將有助於增加第二天線元件的磁通量，進而降低導電元件與傳導材質殼體對第二天線元件所造成的影響。 In summary, the conductive material housing of the present case generates a first annular current in response to the operation of the second antenna element. In addition, the insulating structure extends through the conductive material housing and extends from at least one side of the conductive material housing to the second antenna element. By this, pass The induced current generated by the material housing in response to the first antenna element is converted into a second annular current in the same direction as the first annular current under the barrier of the insulating structure. The second annular current will help increase the magnetic flux of the second antenna element, thereby reducing the effect of the conductive element and the conductive material housing on the second antenna element.
雖然本案已以實施例揭露如上，然其並非用以限定本案，任何所屬技術領域中具有通常知識者，在不脫離本案的精神和範圍內，當可作些許的更動與潤飾，故本案的保護範圍當視後附的申請專利範圍所界定者為準。 Although the present invention has been disclosed in the above embodiments, it is not intended to limit the present case.
