DETAILED DESCRIPTION OF THE INVENTION
FIG. 1 is a diagram illustrating a compound electronic device 100 according to an embodiment of the invention. As shown in FIG. 1, the compound electronic device 100 comprises mobile devices 110, 120 that may be mobile phones, tablet PCs, PDAs, notebooks, or other portable electronic devices with monitors. The mobile device 110 may comprise: an electromagnet 112, a monitor 116, and a storage device 118. The mobile device 120 may comprise: an electromagnet 122, a sensor 124, a monitor 126, and a processor 128. The processor 128 is coupled to the sensor 124 and the electromagnet 122. The electromagnets 112, 122 may consist of coils and an iron core, or only coils. The sensor 124 may be a hall sensor to detect nearby magnetic poles or magnetic fields. The monitors 116, 126 may be LCD (liquid crystal display) monitors. The storage device 118 may be a memory, a hard disc, or DVD.
To begin, the electromagnet 112 of the mobile device 110 generates a first magnetic pole, N pole or S pole. It is noted that an electromagnetic must generate two magnetic poles at two ends concurrently, and the first magnetic pole means a magnetic pole of the electromagnet 112 that generates a magnetic field toward the outside of the mobile device 110. When a distance between the mobile devices 110, 120 is shorter than a predetermined distance, the sensor 124 can detect near by magnetic fields, determine whether the first magnetic pole is an N pole or S pole, and generate an enable signal A1 according to the detection. The processor 128 of the mobile device 120 can determine a current direction of the electromagnet 122 to generate a second magnetic pole opposite to the first magnetic pole according to the enable signal A1. For example, if the first magnetic pole is an N pole, the second magnetic pole is an S pole; and if the first magnetic pole is an S pole, the second magnetic pole is an N pole. Finally, the electromagnets 112, 122 attract each other due to being opposite magnetic poles, and the mobile device 110 is coupled to the mobile device 120 via attraction of the electromagnets 112, 122. When the mobile device 110 is coupled to the mobile device 120, each of the mobile devices 110, 120 generates a vibration alert to inform a user. Although only the sensor 124 of the mobile device 120 detects nearby magnetic fields as shown in FIG. 1, the mobile device 110 can also comprise another sensor and processor and be coupled to the mobile device 120 in the same way. The mobile devices 110, 120 can share data, e.g., video or music files, wirelessly via Bluetooth or Wi-Fi connection.
FIG. 2 is a diagram illustrating displaying an image data together according to an embodiment of the invention. The storage device 118 is configured to store image data 210. Each of mobile devices 110, 120 may comprise an application program. The mobile devices 110, 120 may share the image data 210 wirelessly via the application programs concurrently. The image data 210 may be a movie, a TV program, or a picture. As shown in FIG. 2, the image data can be divided up into sub-images 210a, 210b. When the mobile device 110 is coupled to the mobile device 120, each of the monitors 116, 126 may display part of the image data 210, e.g., the monitors 116, 126 display sub-images 210a, 210b, respectively, to constitute a complete image data 210. Although there are only two mobile devices as shown in FIG. 2, the compound electronic device 100 may comprise 4, 9, or more mobile devices that display one image data together via attraction of the electromagnets.
FIG. 3 is a diagram illustrating a compound electronic device according to an embodiment of the invention. As shown in FIG. 3, a server 310 of an online game is coupled to the mobile devices 110, 120 in a wired or wireless way, and transmits commands B1, B2 to the mobile devices 110, 120, respectively. After connection, the monitor 116 of the mobile device 110 and the monitor 126 of the mobile device 120 may display frames 320a, 320b of the online game according to the commands B1, B2, respectively. For example, the frame 320a is a background, and the frame 320b is a map thumbnail of the online game. In another embodiment, the frames 320a, 320b may be combined to constitute another background of the online game. Through connection of the mobile devices 110, 112, a player can have a larger screen to play the online game.
FIG. 4 is a diagram illustrating a compound electronic device according to an embodiment of the invention. As shown in FIG. 4, a server 410 is coupled to the mobile device 120 in a wired or wireless way, and transmits a control command C1. The electromagnet 122 of the mobile device 120 may comprise a plurality of the sub-electromagnets 122a, 122b, 122c, 122d that are disposed on four sides of the mobile device 120, respectively. Although there are only 4 sub-electromagnets disposed on the 4 sides as shown in FIG. 4, there may be different number of the sub-electromagnets, e.g., 2 sub-electromagnets disposed on 2 sides of the mobile device 120, respectively. During the connection, the mobile device 120 may receive the control command C1 and select one of the plurality of sub-electromagnets according to the control command C1 in order to attract the electromagnet 112 of the mobile device 110. For example, if the control command C1 indicates the sub-electromagnet 122a, the processor (not shown) of the mobile device 120 will command the sub-electromagnet 122a to generate a second magnetic pole with a polarity that is opposite to a polarity of a first magnetic pole of the electromagnet 112. The other sub-electromagnets 122b, 122c, 122d can have no power and can be non-magnetic. Therefore, the mobile device 120 can be coupled to the electromagnet 112 of the mobile device 110 through the sub-electromagnet 122a selected by the server 410.
FIG. 5 is a diagram illustrating a compound electronic device according to an embodiment of the invention. As shown in FIG. 5, the electromagnet 122 of the mobile device 120 may comprise a plurality of the sub-electromagnets 122a, 122b, 122c, 122d that are disposed on four sides of the mobile device 120, respectively. Although there are only 4 sub-electromagnets disposed on the 4 sides as shown in FIG. 5, there may be different number of the sub-electromagnets, e.g., 2 sub-electromagnets disposed on 2 sides of the mobile device 120, respectively. The sensor 124 of the mobile device 120 may comprise a plurality of sub-sensors 124a, 124b, 124c, 124d that are disposed on four sides of the mobile device 120, respectively. Although there are only 4 sub-sensors disposed on the 4 sides as shown in FIG. 5, there may be different number of sub-sensors, e.g., 2 sub-sensors disposed on 2 sides of the mobile device 120, respectively. The sub-sensors 124a, 124b, 124c, 124d detect distances d1, d2, d3, d4 between the electromagnet 112 and the sub-electromagnets 122a, 122b, 122c, 122d, respectively. The processor (not shown) of the mobile device 120 may determine which one is the shortest among distances d1, d2, d3, d4 and select one of the sub-electromagnets 122a, 122b, 122c, 122d that has the shortest distance of all detected distances d1, d2, d3, d4. For example, if the processor determines that the distance d1 is the shortest, it will command the sub-electromagnet 122a to generate a second magnetic pole with a polarity that is opposite to a polarity of a first magnetic pole of the electromagnet 112. The other sub-electromagnets 122b, 122c, 122d can have no power and can be non-magnetic. Therefore, the mobile device 120 can be coupled to the electromagnet 112 of the mobile device 110 through the nearest sub-electromagnet 122a.
FIG. 6 is a diagram illustrating a compound electronic device according to an embodiment of the invention. As shown in FIG. 6, the electromagnet 122 of the mobile device 120 may comprise a plurality of the sub-electromagnets 122a, 122b that are disposed on two sides of the mobile device 120, respectively. Although there are only 2 sub-electromagnets disposed on the 2 sides as shown in FIG. 6, there may be different number of the sub-electromagnets, e.g., 4 sub-electromagnets disposed on 4 sides of the mobile device 120, respectively. The storage device 118 of the mobile device 110 is configured to store image data 210. Each of the mobile devices comprises an application program. Through wireless connection and the application program, the mobile devices 110, 120 may share the image data 210. The image data 210 may be a movie, a TV program, or a picture. The image data 210 may be divided up into sub-images 210a, 210b. To begin, the mobile device 110 is coupled to the mobile device 120, and both display the image data 210 together. Next, the mobile devices 110, 120 are separated from each other, and each of the monitors 116, 126 displays a part of the image data 210, e.g., the monitor 116 displays the sub-image 210a, and the monitor 126 displays the sub-image 210b. If a user wants to combine the mobile devices 110, 120 that are displaying different sub-images, a processor (not shown) of the mobile device 120 will select one of the sub-electromagnets 122a, 122b to be coupled to the electromagnet 112 of the mobile device 110 in order to combine the sub-images 210a, 210b into the complete data image 210. For example, the processor of the mobile device 120 must command the sub-electromagnet 122a to generate a second magnetic pole with a polarity that is opposite to a polarity of a first magnetic pole of the electromagnet 112. The other sub-electromagnet 122b can have no power and can be non-magnetic. Therefore, a wrong combination of mobile devices and a wrong display can be avoided.
