第一金屬感應件25與第二金屬感應件26皆為條狀結構，二者垂直相交地固設在容置槽210內，且與第一磁鐵22和第二磁鐵24不垂直。在本實施方式中，第一金屬感應件25和第二金屬感應件26與第一磁鐵22和第二磁鐵24平行，且與第一磁鐵22和第二磁鐵24之間的磁力線垂直。這樣，在第一金屬感應件25及第二金屬感應件26與第一磁鐵22和第二磁鐵24相對移動時，產生不同方向上的感應電訊號。 The first metal sensing member 25 and the second metal sensing member 26 are both strip-shaped structures, and the two are vertically intersected in the receiving groove 210 and are not perpendicular to the first magnet 22 and the second magnet 24. In the present embodiment, the first metal sensing member 25 and the second metal sensing member 26 are parallel to the first magnet 22 and the second magnet 24 and perpendicular to the magnetic lines of force between the first magnet 22 and the second magnet 24. Thus, when the first metal sensing member 25 and the second metal sensing member 26 move relative to the first magnet 22 and the second magnet 24, inductive electrical signals in different directions are generated.
第一金屬感應件25包括金屬條251及連接在金屬條251兩端的具有導電性能的彈性件252。其中，金屬條251由不會被第一磁鐵22吸引的金屬材料製成，例如金屬條251的材料為銅；彈性件252可以為金屬彈簧或者是金屬彈性杆。彈性件252的一端與金屬條251電性連接，另一端固設在容置槽210側壁的固定孔213中，且藉由導線27與設置在收容部21上的訊號處理單元29電性連接。 The first metal sensing member 25 includes a metal strip 251 and an elastic member 252 having electrical conductivity connected to both ends of the metal strip 251. The metal strip 251 is made of a metal material that is not attracted by the first magnet 22, for example, the material of the metal strip 251 is copper; and the elastic member 252 may be a metal spring or a metal elastic rod. One end of the elastic member 252 is electrically connected to the metal strip 251, and the other end is fixed in the fixing hole 213 of the side wall of the receiving groove 210, and is electrically connected to the signal processing unit 29 disposed on the receiving portion 21 by the wire 27.
第二金屬感應件26包括金屬條261及連接在金屬條261兩端的具有導電性能的彈性件262。其中，金屬條261由不會被第二磁鐵24吸引的金屬材料製成，例如金屬條261的材料為銅；彈性件262可以為金屬彈簧或者是金屬彈性杆。彈性件262的一端與金屬條261電性連接，另一端固設在容置槽210的固定孔214中，且藉由導線28與設置在收容部21上的訊號處理單元29電性連接。 The second metal sensing member 26 includes a metal strip 261 and an elastic member 262 having electrical conductivity connected to both ends of the metal strip 261.

當左右和前後晃動便攜式電子裝置10時，因為動作感應器60中的金屬條251及彈性件252都存在慣性而不能及時與收容部21一起運動，使得連接在容置槽210側壁與金屬條251之間的彈性件252發生形變，進一步地，彈性件252的形變會積蓄彈力，在慣性和彈力的作用下金屬條251會相對第一磁鐵22和第二磁鐵24發生移動，從而切割磁力線產生感應電訊號。請同時參看圖5，金屬條251切割磁場中的磁力線並產生第一感應電訊號。同樣地，在彈性件262彈力的作用下金屬條261發生移動。金屬條261切割磁場中的磁力線而產生第二感應電訊號。訊號處理單元29用於接收第一感應電訊號及第二感應電訊號並對該兩個感應電訊號進行過濾及放大操作後提供給處理模組30。 When the portable electronic device 10 is shaken left and right and back and forth, because the metal strip 251 and the elastic member 252 in the motion sensor 60 have inertia, they cannot move together with the accommodating portion 21 in time, so that the side wall of the accommodating groove 210 and the metal strip 251 are connected. The elastic member 252 is deformed. Further, the deformation of the elastic member 252 accumulates the elastic force. Under the action of inertia and elastic force, the metal strip 251 moves relative to the first magnet 22 and the second magnet 24, thereby cutting the magnetic field lines to generate induction. Telecommunications signal. Referring also to FIG. 5, the metal strip 251 cuts the magnetic lines of force in the magnetic field and generates a first inductive electrical signal. Similarly, the metal strip 261 moves under the elastic force of the elastic member 262. The metal strip 261 cuts magnetic lines of force in the magnetic field to produce a second inductive electrical signal. The signal processing unit 29 is configured to receive the first inductive signal and the second inductive signal and filter and amplify the two inductive signals to be provided to the processing module 30.
處理模組30根據訊號處理單元29提供的第一感應電訊號及第二感 應電訊號產生第一執行訊號及第二執行訊號以分別控制鍵盤鎖控制模組40及背光控制模組60。其中，處理模組30將第一感應電訊號與第一預設值進行比較，在第一感應電訊號大於該第一預設值時產生第一執行訊號；處理模組30將第二感應電訊號與第二預設值進行比較，在第二感應電訊號大於該第二預設值時產生第二執行訊號。鍵盤鎖控制模組40回應第一執行訊號，使鍵盤50有效。背光控制模組60回應第二執行訊號，控制顯示模組70開啟背光。 The first inductive signal and the second sense provided by the processing module 30 according to the signal processing unit 29 The first execution signal and the second execution signal are generated by the electrical signal to respectively control the keyboard lock control module 40 and the backlight control module 60. The processing module 30 compares the first inductive signal with the first preset value, generates a first execution signal when the first inductive signal is greater than the first preset value, and the second inductive telecommunications by the processing module 30 The number is compared with the second preset value, and the second execution signal is generated when the second inductive signal is greater than the second preset value. The keyboard lock control module 40 responds to the first execution signal to make the keyboard 50 valid. The backlight control module 60 responds to the second execution signal and controls the display module 70 to turn on the backlight.
在其他實施方式中，可以是第一金屬感應件25與第二金屬感應件26固定，而第一磁鐵22和第二磁鐵24可以在容置槽210中移動。另外，第一金屬感應件25與第二金屬感應件26也可以利用一個U形磁鐵代替。容置槽210可只固設一個金屬感應件來產生感應電訊號，處理模組30根據該金屬感應件提供的感應電訊號產生的執行訊號；動作感應器20產生的感應電訊號還可以觸發便攜式電子裝置10執行其他的功能，例如播放歌曲、增大或減小音量等。 In other embodiments, the first metal sensing member 25 and the second metal sensing member 26 may be fixed, and the first magnet 22 and the second magnet 24 may move in the receiving groove 210. In addition, the first metal sensing member 25 and the second metal sensing member 26 may also be replaced by a U-shaped magnet. The accommodating slot 210 can fix only one metal sensing component to generate an inductive electrical signal, and the processing module 30 generates an execution signal according to the inductive electrical signal provided by the metallic sensing component; the sensing electrical signal generated by the motion sensor 20 can also trigger the portable signal. The electronic device 10 performs other functions such as playing a song, increasing or decreasing the volume, and the like.
當用戶晃動便攜式電子裝置10時，動作感應器20中的第一金屬感應件25和第二金屬感應件26在慣性及其自身形變產生的彈力的作用下切割兩個磁性體之間磁場中的磁力線以產生感應電訊號，從而使鍵盤50有效以及控制顯示模組70開啟背光，用戶不需要按壓解鎖按鍵便可開啟便攜式電子裝置10的背景燈並解開鍵盤鎖，為用戶提供了操作上的方便，也使得便攜式電子裝置10更加個性化。 When the user shakes the portable electronic device 10, the first metal sensing member 25 and the second metal sensing member 26 in the motion sensor 20 cut the magnetic field between the two magnetic bodies under the action of the inertia and the elastic force generated by the deformation thereof. The magnetic lines of force generate an inductive electrical signal, thereby enabling the keyboard 50 to be effective and controlling the display module 70 to turn on the backlight. The user can turn on the backlight of the portable electronic device 10 and unlock the keyboard lock without pressing the unlock button, thereby providing the user with an operation. Convenience also makes the portable electronic device 10 more personalized.
