1 shows an electronic device to which an external device according to various embodiments is connected.

Referring to FIG. 1, the electronic device 110 may be physically or electrically connected to the external device 150 for user convenience or function expansion. The electronic device 110 may correspond to a device such as a smart phone, a tablet PC, and the like. The electronic device 110 can recognize and utilize the operation of the external device 150 (e.g., the moving distance or the opening angle). For example, the electronic device 110 determines the opening angle of the external device 150, such as a flip cover, and performs an operation of turning on or off according to the angle, Execution of a specified application, etc.).

The electronic device 110 may include a sensing portion 120 that can recognize a magnetic field. The sensing unit 120 may be disposed at a position corresponding to (or adjacent to) the magnet unit 160 included in the external device 150. The arrangement of the sensing unit 120 shown in FIG. 1 is merely an example, and is not limited thereto. For example, the sensing unit 120 may be disposed at a portion of the front upper or lower end of the electronic device 110. The sensing unit 120 may be disposed on a side surface or a rear surface of the electronic device 110 to recognize a magnetic field generated in the magnet unit 160.

The sensing unit 120 (e.g., Hall sensor) may include a plurality of Hall elements to recognize a magnetic field generated in the magnet unit 160. [ The plurality of Hall elements may be elements that recognize the direction and magnitude of the magnetic field using a Hall effect. The Hall effect is an effect that a voltage is generated in a direction perpendicular to a current and a magnetic field when a magnetic field is applied to the conductor. The voltage generated by the Hall effect may be proportional to the applied current and the intensity of the magnetic field. The information about the magnetic field recognized by each of the Hall elements can be utilized to determine the operation of the external device 150 (e.g., the moving distance or the opening angle).

The external device 150 may be used in connection with the electronic device 110 for user convenience or function expansion. The external device 150 may correspond to a flip cover, a wireless charging device, a speaker device, and the like. In various embodiments, the external device 150 may be a device that is placed adjacent to the electronic device 110, even if it is not electrically and physically connected directly. For example, the external device 150 may correspond to a wireless keyboard device disposed adjacent to the electronic device 110 and may be connected to the electronic device 110 via a separate connection module (e.g., device connection cover). The electronic device 110 can sense movement of the adjacent external device 150 or change in the angle. Hereinafter, the case where the external device 150 is directly connected to the electronic device 110 is described, but it can also be applied to the case where the external device 150 is disposed adjacent thereto.

According to various embodiments, the external device 150 may be implemented as being integrally connected to the electronic device 110. When the electronic device 110 and the external device 150 are integrally implemented, the electronic device 110 constitutes a first main body, and the external device 150 constitutes a second main body. For example, in the case of a notebook PC, the electronic device 110 corresponds to a first main body including a keyboard, and the external device 150 corresponds to a second main body including a display. Hereinafter, a case where the external device 150 is formed separately from the electronic device 110 is described, but the present invention is not limited thereto, and various embodiments may be applied to the case where the external device 150 is integrally formed.

The external device 150 may include a magnet portion 160 that generates a magnetic field. The magnet portion 160 may be disposed in a portion of the external device 150 to generate a magnetic field. In various embodiments, the magnet portion 160 may be disposed at a position corresponding to the sensing portion 120. For example, if the external device 150 is a flip cover, the magnet portion 160 may be disposed at a point on the flip cover that may overlap the sensing portion 120 when the flip cover is covered by the electronic device 110. [ However, the magnet portion 160 need not overlap with the sensing portion 120 as a whole, but may be disposed so as to overlap only a part thereof. Further, the magnet portion 160 may be arranged adjacent to the sensing portion 120 within a range where the magnetic field can be recognized by the hole element.

According to various embodiments, the magnet portion 160 may be implemented in various forms according to the position and the charge area disposed on the external device 150, the polarity or arrangement of the surface adjacent to the sensing portion 120 (e.g., horizontal / vertical arrangement) . Information on the shape of the magnet portion 160 can be provided through Fig.

Figure 2 shows a block diagram of a sensing unit according to various embodiments.

Referring to FIG. 2, the sensing unit 120 may include a plurality of hole elements 210 and a control unit 220.

The plurality of Hall elements 210 are disposed inside the sensing unit 120 to recognize a magnetic field generated in the magnet unit 160. The plurality of hall elements 210 may be elements that recognize the direction and magnitude of the magnetic field using a Hall effect.

Each of the plurality of hole elements 210 can recognize intensity of another magnetic field according to a distance from the magnet portion 160. For example, if the Hall element 1 is at a distance R1 from the magnet portion 160 and the Hall element 2 is at a distance of R2 (> R1) from the magnet portion 160, the intensity of the magnetic field measured at the Hall element 1 is the Hall element 2 Lt; RTI ID = 0.0 & The plurality of hall elements 210 can provide the control unit 220 with recognition information such as intensity or direction of the measured magnetic field. The recognition information may be used to determine the operation of the external device 150 (e.g., position, angle, or travel distance).

According to various embodiments, the sensing unit 120 may further include a conversion unit 215 between the plurality of hole elements 210 and the control unit 220. [ The conversion unit 215 may convert or process the information measured in the plurality of hole elements 210 and provide the processed information to the control unit 220. The conversion unit 215 may include an amplifier, an offset adjustment unit, and the like. Information regarding the conversion unit 215 may be provided through FIG.

The control unit 220 can determine the operation (e.g., position, angle, or movement distance) of the external device 150 based on the recognition information measured at the plurality of hole elements 210. The control unit 220 can determine the position or movement direction of the magnet unit 160 based on the recognition information measured in each of the hall elements. The control unit 220 can determine the movement (e.g., the left / right swinging movement, the rotary swinging movement, the opening / closing operation, etc.) or the opening angle of the external device 150 based on the information about the operation of the magnet unit 160. In various embodiments, the controller 220 may determine the position or movement direction of the magnet unit 160 based on differences, ratios, or patterns of recognition information measured at each of the hall elements. The information determined through the control unit 220 may be provided to a processor (AP) 230 inside the electronic device 110. 2, the control unit 220 is formed separately from the processor (AP) 230 in the electronic device 110. However, the present invention is not limited thereto. The control unit 220 may be implemented in a form included in the processor.

According to various embodiments, the controller 220 determines the operation of the external device 150, such as the position, the angle, or the moving distance, and turns the electronic device 110 on or off according to the operation, Example: running the specified UX, running the specified application, etc.). Information regarding the operation of the control unit 220 may be provided through Figs.

According to various embodiments, the control unit 120 may be coupled to the storage unit 240. The storage unit 240 may store information related to the recognition of the operation of the external device 150. In various embodiments, the storage unit 240 may store a reference table related to the type of the external device 150. The reference table may include a condition corresponding to each type of external device 150. [ For example, the reference table may include information about the polarity, position, or strength of the magnetic field of the magnet unit 160 according to the type of the external device 150.

In various embodiments, the look-up table may store association information according to the type of each external device 150. The association information may include information for identifying or specifying the device such as the type, size, color material, manufacturer, operation reference value, and the like of the external device 150.

The control unit 220 can determine the type of the external device 150 by comparing the information recognized through the plurality of hole elements 210 with the conditions stored in the reference table. When the type of the external device 150 is determined, the controller 120 can determine the operation of the external device 150 based on the operation reference value determined according to the type of the external device 150. For example, when the reference table is as shown in [Table 1] below, when the result based on the information recognized through the plurality of hole elements 210 is determined to be (N pole, first position, strong) 150 types can be determined as type 1.

polarity Position of magnet part Strength of a magnetic field Type 1 N First location River Type 2 N Second location River Type 3 S 3rd position River Type 4 S 3rd position about

The control unit 220 can operate according to various types of external apparatuses 150 even if the maker of the external apparatus 150 is changed or the position of the magnet unit 160 is changed through the reference table.

3 shows an example of implementation of a sensing unit according to various embodiments.

Referring to FIG. 3, the sensing unit 120 may include a plurality of Hall elements 310, a conversion unit 315, and a control unit 320. However, the sensing unit 120 is illustratively shown in FIG. 3. However, the present invention is not limited thereto.

The plurality of hole elements 310 may include four hole elements (holes A to D). Although FIG. 3 exemplifies the case including four hole elements, the present invention is not limited thereto. If the number of the Hall elements included in the sensing unit 120 is increased, the recognition accuracy of the external device 150 can be improved, but the data processing amount may increase and the processing speed may be slowed down. The number of the hole elements can be determined in consideration of the performance of the electronic device 110 or the characteristics of the external device 150 and the like.

The conversion unit 315 may convert or process the recognition information measured in the plurality of hole elements 310 and provide the converted information to the control unit 320. The converting unit 315 may include an amplifier 316 and a converter 317. The amplifier 316 can amplify the recognition information (e.g., raw data for the intensity or direction of the magnetic field) of each of the plurality of hall elements 310. Since the plurality of hall elements 310 are disposed in a limited space inside the sensing unit 320, the difference in recognition result of the magnetic field may not be large. The amplifier 316 amplifies the recognition information, and the control unit 320 can convert the result to facilitate utilization of the result. The converter 317 may correspond to an analog to digital converter (ADC) that converts recognition information, which is an analog signal, into a digital signal. The converter 317 may convert the recognition information into a digital signal and provide the digital signal to the control unit 320.

According to various embodiments, the conversion unit 315 may further include an offset adjustment unit (not shown). The offset adjustment unit may adjust the offset to the recognition information measured in the plurality of hole elements 310. [

The control unit 320 can determine the operation (e.g., position, angle, or moving distance) of the external device 150 based on the recognition information (or information converted through the conversion unit 315) measured in the plurality of hole elements 310.

Figure 4 illustrates the arrangement of a plurality of hole elements within a sensing portion according to various embodiments.

Referring to FIG. 4, the Hall elements 410a to 410d may be disposed inside the sensing unit 120. FIG. 4, the arrangement of the four Hall elements is shown. However, the present invention is not limited to this, and a variety of Hall elements such as two, three, four or eight Hall elements may be included in the sensing unit 120.

Referring to FIG. 4A, the hole elements 410a to 410d may be disposed horizontally in the direction of the front surface of the sensing unit 120 (for example, a surface parallel to the front surface of the electronic device 110). The hole elements 410a to 410d may be arranged adjacent to the front vertex of the sensing unit 120. [ However, the present invention is not limited thereto, and the hole elements 410a to 410d may be arranged adjacent to the center of each side of the front surface of the sensing unit 120. [

The distance between the Hall elements 410a to 410d and the magnet unit 160 may vary depending on the position of the Hall elements 410a to 410d, and the strength or direction of the magnetic field measured in each Hall element may vary depending on the distance difference. The information recognized through the hall elements 410a to 410d may be provided to the control unit 220 and utilized for recognizing the operation of the external device 150. [ In various embodiments, the Hall elements 410a through 410d may be arranged to maintain more than a specified distance from each other within the sensing portion 120. [ As the distance between the respective hole elements increases, the difference in the measured recognition information can be increased, and the recognition efficiency for the external device 150 can be increased accordingly.

Referring to FIG. 4B, the hole elements 420a to 420d may be disposed on the side of the sensing portion 120 (e.g., a surface parallel to the side surface of the electronic device 110). The hole elements 420a to 420d may be disposed adjacent to the side vertexes of the sensing portion 120. [ 4A, the hole elements 420a and 420c (or the hole elements 420b and 420d) are disposed relatively adjacent to each other, so that the difference in recognition information about the magnet part 160 may not be large.

According to various embodiments, the sensing unit 120 may include a variety of hole elements on the front or side. For example, the sensing unit 120 may include eight hole elements on the front surface or the side surface in a combination of FIG. 4 (a) and FIG. 4 (b).

FIG. 5 illustrates a manner in which the controller determines the position or angle of an external device according to various embodiments.

5, the control unit 220 sets the origin (0, 0, 0) of the rectangular coordinate system to a designated point (for example, a lower left corner of the front left corner - a virtual vertex point where each side extends in the case of a circular finish) . The sensing unit 120 may be disposed at the coordinate A (x0, y0, 0) with respect to the origin. Hereinafter, a method of determining the coordinates B (x1, y1, z1) of the magnet unit 160 based on the coordinate A (x0, y0, 0) of the sensing unit 120 will be examined.

The control unit 220 can determine the Y coordinate y1 of the magnet unit 160 based on the intensity of the magnetic field measured at the hole element 510a and the hole element 510b (or based on the intensity of the magnetic field measured at the hole element 510c and the hole element 510d) have. For example, when the intensity of the magnetic field measured at the hole element 510a and the Hall element 510b is the same, the controller 220 can determine y1 to be equal to y0. Alternatively, if the intensity of the magnetic field measured at the Hall element 510a is greater than the intensity of the magnetic field measured at the Hall element 510b, then the controller 220 may determine that y1 is greater than y0 (which may increase proportionally with the intensity difference of the measured magnetic field) You can decide. Conversely, when the intensity of the magnetic field measured at the Hall element 510a is smaller than the intensity of the magnetic field measured at the Hall element 510b, the controller 220 can determine y1 to be a value smaller than y0.

The control unit 220 determines the X-axis coordinate x1 of the magnet unit 160 based on the intensity of the magnetic field measured at the hole element 510a and the hole element 510c (or based on the intensity of the magnetic field measured at the hole element 510b and the hole element 510d) . For example, when the intensity of the magnetic field measured by the Hall element 510a and the Hall element 510c is the same, the controller 220 may determine x1 to be equal to x0. Alternatively, if the intensity of the magnetic field measured at the Hall element 510a is greater than the intensity of the magnetic field measured at the Hall element 510c, the controller 220 may determine x1 to be a value less than x0. Conversely, if the intensity of the magnetic field measured at the Hall element 510a is less than the intensity of the magnetic field measured at the Hall element 510c, the controller 220 may determine x1 to be a value greater than x0.

The control unit 220 can determine the z-axis coordinate z1 of the magnet unit 160 based on the intensity of the magnetic field measured at at least one of the hall elements 410a to 410d. For example, the controller 220 may determine z1 as a zero value when the average value of the magnetic field strength measured at the hole elements 510a to 510d exceeds the specified reference value. In addition, when the average value of the intensity of the magnetic field measured in the hole elements 510a to 510d is included between the designated interval values, the controller 220 can determine the coordinate value set in the corresponding interval as z1. In various embodiments, the controller 220 may determine z1 according to a hysteresis function. For example, when the external device 150 is a flip cover, the controller 220 determines the z1 coordinate according to the first reference value when the external device 150 moves in the opening direction. If the external device 150 moves in the closing direction, The z1 coordinate can be determined by two reference values.

According to various embodiments, the controller 220 can determine the angle of the external device 150 based on the position information of the magnet unit 160. [ For example, the control unit 220 can determine the angle of the external device 150 based on the coordinate value (x1 or z1) of the X axis or the Z axis in the position information of the magnet unit 160. [ For example, the controller 220 may determine the angle of the external device 150 based only on the coordinate value z1 of the Z axis. In this case, the controller 220 can determine the angle of the external device 150 according to the coordinate value of the Z-axis using a matching table between z1 and an angle set in advance.

According to various embodiments, the controller 220 may determine the relative position of the magnet unit 160 with respect to the sensing unit 120. For example, the control unit 220 can relatively determine the position of the magnet unit 160 according to whether the position of the magnet unit 160 is at the upper end or the lower end of the position corresponding to the sensing unit 120, or at a certain distance.

Fig. 6 shows a change in distance from the hole element due to the movement of the magnet portion according to various embodiments.

6A shows a change in distance from the hole element due to horizontal movement of the magnet portion 160 (for example, left-right swinging movement or rotational swinging movement of the flip cover). 6A, when the magnet portion 160 moves in the X-axis direction or the Y-axis direction, the distances R1 to R4 between the hole elements 610A to 610D and the magnet portion 160 may change according to the movement . For example, when the magnet portion 160 moves in the (+) direction of the X-axis in a state where the magnet portion 160 overlaps with the sensing portion 120 as a whole, R1 to R4 can be both large. In this case, the intensity of the magnetic field recognized by the hall elements 610A to 610D can be all reduced. However, the change in R2 or R3 may be relatively larger than the change in R1 or R4. Accordingly, the change in the magnetic field strength recognized by the Hall element 610B or 610C may be relatively larger than the change in the magnetic field strength recognized by the Hall element 610A or 610D.

The controller 220 can determine the moving direction or the moving distance of the external device 150 based on the change of the magnetic field generated in each of the hole elements. The control unit 220 can execute the designated function of the electronic device 110 when the moving direction or the moving distance of the external device 150 is determined. For example, when the movement of the magnet unit 160 in the X-axis direction or the Y-axis direction is within the specified range, the control unit 220 maintains the electronic device 110 in the turn-off state, It can be recognized by the user.

6 (b) shows a change in distance from the hole element due to vertical movement of the magnet portion 160 (e.g., opening or closing of the flip cover). Referring to FIG. 6B, when the magnet portion 160 moves in the Z-axis direction, the distances R1 to R4 between the hole elements 610A to 610D and the magnet portion 160 may change according to the movement. For example, when the magnet portion 160 moves in the positive (+) direction of the Z-axis, R1 to R4 can be both large. In this case, the intensity of the magnetic field recognized by the hall elements 610A to 610D can be all reduced. However, when the magnet portion 160 is connected to the external device 150 such as a flip cover, the change of R2 or R3 may be relatively smaller than the change of R1 or R4 in accordance with the Z (+) direction movement. Accordingly, the change in the magnetic field strength at the hole element 610B or 610C may be relatively smaller than the change in the magnetic field strength at the hole element 610A or 610D.

The control unit 220 can determine the operation of the external device 150 based on the change in the magnetic field occurring in each of the hall elements and thereby perform the specified function of the electronic device 110. [ For example, when the movement of the magnet unit 160 in the Z-axis direction is within the specified range, the controller 220 may maintain the electronic device 110 in the turn-off state and turn on the electronic device 110 when the movement is out of the specified range.

FIG. 7 shows a graph showing changes in magnetic field strength with movement of an external device according to various embodiments.

7, the magnetic field strength recognized in each of the Hall elements A through D can be determined by the state of the external device 150 (e.g., a flip cover) (e.g., a closed state, a left-right moving state, a rotating moving state, 360 degrees, 360 degrees to 0 degrees)).

In the closed state 710, the magnet portion 160 may be disposed adjacent to the sensing portion 120. In the graph 710a, the intensity of the magnetic field recognized by the Hall elements A to D can be formed with a relatively small variation width and a large value. The control unit 220 may determine the external device 150 to be in the closed state based on the strength of the magnetic field or the variation width.

In the left-right moving state 720, the magnet portion 160 can move together with the left and right movement of the external device 150. In graph 720a, the intensity of the magnetic field recognized by the Hall elements A through D may be greater than the closed state 710. [ The strength of the magnetic field recognized in the Hall elements A through D may be greater than the open state 740. [ The control unit 220 can determine the external device 150 to be in the left-and-right movement state based on the intensity of the magnetic field, the variation width, or the like.

In the rotational movement state 730, the magnet portion 160 can move together with the rotational movement of the external device 150 (e.g., the electronic device 110 and the external device 150 are pushed up and down in a connected state). In graph 730a, the intensity of the magnetic field recognized by the Hall elements A through D may be greater than the closed state 710. [ The intensity of the magnetic field recognized by the Hall elements A to D may have a shape that changes similarly to the groups (e.g., the Hall elements A and D, and the Hall elements B and C) unlike the left and right movement states 720. The control unit 220 may determine the external device 150 to be in a rotationally moving state based on the intensity of the magnetic field, the variation width, or the like.

In the open state 740, the magnet portion 160 can move together with the opening movement (decrease in the X axis direction, increase in the Z axis direction) of the external device 150.
