Wireless Telecom Equipment 100 can comprise two magnets 303,313, single magnetic sensor 305 co-operations of itself and equipment and cause the switching for the change of display backlight between Kai Heguan when equipment opens and closes.Magnetic sensor 305 can change due to the spatial limitation of equipment 100 with respect to the position of magnet 303,313, but magnetic transducing should be preferably in being convenient to the optimum detection of the magnetic field from described magnet or magnetic flux or the position of reading.For an embodiment, magnetic sensor 305 can be positioned at position equidistant as far as possible with magnet 303,313 between magnet 303,313.For another embodiment, magnetic sensor can be positioned at certain between magnet 303,313.
A magnet 303 is fixed, yet another magnet 313 can rotate and rotate or move for 410 o'clock at Wireless Telecom Equipment.Each magnet 303,313 comprises the arctic 317,319 and the South Pole 321,323.When equipment in the closed position 300, as shown in Figure 3, the polarity of magnet 303,313 is in contrary direction, therefore the South Pole 323 of the second magnet 313 is pointed in the South Pole 321 of the first magnet 303, and the arctic 319 that the arctic 317 of the first magnet is pointed to away from the second magnet.When equipment in an open position 400, as shown in Figure 4, magnet 303,313 polarity is positioned at similar direction, therefore the identical direction in the South Pole 323 that the South Pole 321 of the first magnet 303 is pointed to as the second magnet 313, and the arctic 317 of the first magnet and the arctic 319 of the second magnet are pointed to identical direction each other, but be contrary direction with the South Pole of magnet.When Wireless Telecom Equipment 100 is configured to primary importance 300 (as closing in Fig. 3), magnetic pole 317,319,321,323 by identical direction, and the magnetic flux detecting at magnetic sensor 305 can be the magnetic flux sum from magnet 303,311.As a result, in this case, device display can be not illuminated, lost efficacy " closing ".When Wireless Telecom Equipment 100 is configured in the second place 400 (as opening in Fig. 4), magnetic pole 317,319, and 321,323 will be in the opposite direction, and the magnetic flux detecting at magnetic sensor can be two counteractings between magnet 303,311.As a result, in this case, device display can be illuminated, activates " opening ".
When environment division is in an open position, the polarity of magnet 303,313 can substantial lateral (transverse).For example, when the position of the magnetic pole of the first magnet 303 can be constant, (from visual angle as shown in Figures 3 and 4) can be pointed in the South Pole of the second magnet 313, and the arctic of the second magnet can be pointed to down.
With reference to figure 5, show illustration by the Figure 50 0 in the various magnetic fields that magnet provides according to an embodiment of the invention.Figure 50 0 shows the upper limit of magnetic flux 510, the lower limit of magnetic flux 520, the magnetic flux 530 being provided by the second magnet 313, the magnetic flux 540 being provided by the first magnet 303, and the magnetic flux 550 of the combination being received from two magnets by magnetic sensor 305.As shown in Figure 5, the magnetic flux 520 being provided by the first magnet 303, when the magnetic flux 530 with being provided by the second magnet 313 combines, the magnetic flux 550 that offers combination is offset accordingly.
The function that is arranged in the second magnet 313 of hinge 311 is to provide transformable magnetic field during around hinge through when Wireless Telecom Equipment 100.The magnetic flux being received by magnetic sensor 305 is cosine curve 530 as shown in Figure 5.When shell 301,309 is opened with the first angle, (as about 28 degree), the magnetic flux 530 being provided by the second magnet 313 can intersect with the upper limit 510 of magnetic flux 1: 560.For example, if display illumination based on device structure, display illumination zero degree and 28 degree between can lose efficacy, " close ".For example, when shell 301,309 is opened with the second angle (about 152 degree), the magnetic flux 530 being provided by the second magnet 313 can intersect at second point 570 and the lower limit 520 of magnetic flux.For example, if display illumination based on device structure, display illumination can be activated between 28 degree and 152 degree, " opens ", and spends time inefficacy when being greater than 152.Due to expectation display illumination when the device shutdown " close " and when equipment is opened display illumination " open ", so the second magnet 313 it seems cannot provide separately enough information to magnetic sensor 305 with other parts to complete this task.
The function of the first magnet 303 that is arranged in the non-hinge fraction of the first shell 301 is when hinge 311 rotates, indeclinable magnetic field to be increased to the transformable magnetic field being provided by the second magnet 313 when Wireless Telecom Equipment 100.As shown in Figure 5, the magnetic flux being received by magnetic sensor 305 is that cosine curve 530 forms after the linearity skew being caused by described not varying magnetic field.When device shutdown, the South Pole 321 of the first magnet 303 is pointed in the South Pole 323 of the second magnet 313.Because magnetic sensor 305 is positioned between magnet 303,313, magnetic flux field intensity is accumulated, and for example, is greater than as shown in Figure 5 50Gs.When equipment is opened, the South Pole 321 of the first magnet 303 is pointed in the arctic 319 of the second magnet 313.Total magnetic flux field intensity almost can disappear mutually, and the magnetic flux therefore being detected by magnetic sensor 305 is less than 20Gs, for example, is less than as shown in Figure 5-20Gs.
Or with reference to figure 5, when shell 301,309 is opened with the 3rd angle, (for example about 65 degree), the magnetic flux being provided by the first and second magnets 303,313 can thirdly 580 intersect with the magnetic flux upper limit 510.For example, if the structure of display illumination based on equipment, display illumination can lose efficacy between zero degree and 65 degree, " closed ".For example, when shell 301,309 is opened to surpass the 3rd angle (being greater than 65 degree), the magnetic flux being provided by the first and second magnets 303,313 can not intersect with the lower limit 520 of magnetic flux.For example, if display illumination, based on device structure, is opened and is greater than 65 while spending when equipment, display illumination can be activated, and " opens ".Due to expectation display illumination when the device shutdown " close " and when equipment is opened display illumination " open ", the invention provides enough information to magnetic sensor 305 with other parts to complete this task.
Although illustration and described the preferred embodiments of the present invention, should be appreciated that the present invention is not limited only to this.Can carry out multiple modification for those skilled in the art, change, change, substitute and be equal to, and not departing from the spirit and scope of the present invention that defined by the claim of adding.
