5 is a diagram illustrating an example in which a geomagnetic sensor and a magnet are disposed in an electronic device according to various embodiments of the present disclosure;

Referring to FIG. 5 , a first drawing 510 is an electronic device (eg, the electronic device 101 of FIG. 1 , the electronic device 200 of FIGS. 2 and 3 , and the electronic device of FIG. 4 ) according to various embodiments. 400), and the second drawing 550 is a cross-sectional view of the first drawing 510 taken along the A direction (eg, indicated by a dotted line). The size ratios of the components shown in the drawings are arbitrarily illustrated for convenience of description, and the size ratios of the components may be changed.

Referring to the first drawing 510 , the electronic device 200 may include a geomagnetic sensor 515 , a magnet 520 , and a wheel key 530 . The geomagnetic sensor 515 is a sensor for detecting geomagnetism, and may detect a direction (eg, azimuth) of the geomagnetism. The electronic device 200 may display an azimuth using the geomagnetic sensor 515 or provide directions of east, west, south, and north like a compass. Since the geomagnetic sensor 515 is affected by a magnet, it may malfunction if a magnet is present around it. The geomagnetic sensor 515 may be disposed in the center of the electronic device 200 . For example, as shown in the drawing, when the housing of the electronic device 200 (eg, the housing 210 of FIG. 2 ) has a circular shape, the geomagnetic sensor 515 may be disposed at the center of the circular shape.

The magnet 520 may be disposed on the rear surface (eg, the rear plate 493 of FIG. 4 ) of the housing 210 of the electronic device 200 . For example, the magnet 520 positioned on the rear surface of the electronic device 200 may be for alignment with a charging device (eg, a charging pad). The size of the magnet 520 , the number of magnets 520 , or the position of the magnet 520 may be determined in consideration of the tensile force with the charging pad. For example, the magnet 520 may be disposed on the rear surface of the housing 210 facing the geomagnetic sensor 515 when the front surface of the housing 210 is viewed from above. When the electronic device 200 is formed to be worn on the user's wrist, the rear surface of the housing 210 may refer to an area in direct contact with the user's wrist. The magnet 520 may be disposed to have a predetermined distance from the geomagnetic sensor 515 in consideration of the effect of magnetic force on the geomagnetic sensor 515 .

The magnet 520 has a characteristic that the generation of magnetic force is reduced (or suppressed) in a specific direction (eg, center direction, vertical direction) in which the geomagnetic sensor 515 is disposed in order to reduce the influence of the magnetic force on the geomagnetic sensor 515. can have The magnet 520 may be arranged horizontally, vertically, or diagonally with the N and S poles of at least two magnets. The magnet 520 may have a characteristic of reducing the generation of magnetic force in a vertical direction by using a plurality of divided magnets. For example, the magnet 520 may have a characteristic that the magnetic force strength is reduced in a specific direction by combining the arrangement structure of the N pole and the S pole of at least two magnets in a horizontal direction or a vertical direction. The magnet 520 having these characteristics may be, for example, an oblique magnet or a Halbach magnet (or a Halbach array magnet). The diagonal magnet has a center of 2100G when implemented as a barrel, but it may mean that the center area is lowered to 600G through a piece. For example, when the polarity of a diagonal magnet is arranged diagonally, the upper surface (eg, N pole) of the diagonal magnet has a reduced magnetic force around the center of the magnet, the magnetic force in the outward direction is strong, and the lower surface of the diagonal magnet ( Example: S pole) may have a strong magnetic force around the center of the magnet and weak magnetic force in the outer direction. When using such a diagonal magnet as the magnet 520 for wireless charging, the magnet 520 may be disposed in a direction facing the geomagnetic sensor 515 without a shielding agent for blocking magnetic force. The diagonal magnet or Halbach magnet is an example for helping understanding of the invention, and the present invention is not limited by the example.

The wheel key 530 may be configured to be rotatable in at least one direction along the outer circumferential surface of the housing 210 . For example, the wheel key 530 may be rotatable in a clockwise or counterclockwise direction. One or more magnets 531 to 538 may be disposed for operation of the wheel key 530 . For example, when the housing 210 is circular, one or more magnets 531 to 538 may be disposed along the outer circumferential surface of the wheel key 530 at intervals of 45°. For example, one or more magnets 531 - 538 may be oriented clockwise, with the first magnet 531 at 0° (eg 12 o'clock), 45° (eg between 12 and 3 o'clock (middle) direction). Second magnet 532, third magnet 533 at 90° (eg 3 o’clock), fourth magnet 534 at 135° (eg between 3 o’clock and 6 o’clock), 180° (eg: 6 o'clock) a fifth magnet 535, a sixth magnet 536 at 225° (eg between 6 o'clock to 9 o'clock), a seventh magnet 537 at 270° (eg 9 o'clock), An eighth magnet 538 may be disposed at 315° (eg, a direction between 9 o'clock and 12 o'clock). The position or number of one or more magnets 531 to 538 disposed on the wheel key 530 may vary depending on implementation. The drawings are only examples to help the understanding of the present invention, and the present invention is not limited by the drawings.

According to various embodiments, since one or more magnets 531 to 538 are disposed on the wheel key 530 , when operating the wheel key 530 , the change of the magnetic field generated in the one or more magnets 531 to 538 .

In order to prevent such a malfunction, the geomagnetic sensor 515 may be disposed in the center of the housing 210 , which is the most unaffected by the operation of the wheel key 530 .

Referring to the second drawing 550 , the geomagnetic sensor 515 may be disposed inside the display panel 593 of a display (eg, the display 220 of FIG. 2 ) or below the display panel 593 . Alternatively, the geomagnetic sensor 515 may be disposed on the first printed circuit board 480 , or some electrical components (eg, wires, circuits) attached to the rear surface of the display 220 are removed and disposed at the removed position. have. This is only an implementation issue, and the present invention is not limited by way of example. The display 220 may be disposed on the front side of the housing 210 . In the display 220 , a window 591 for protecting the display panel 593 is disposed on the front of the housing 210 , and the display panel 593 is located under the window 591 with respect to the front of the housing 210 . may be included. Below the display 220 is a speaker 580 (eg, the sound output module 155 of FIG. 1 , the speaker hole 208 of FIG. 2 ) and a battery (eg, the battery 189 of FIG. 1 and the battery of FIG. 4 ). (470)).

A first printed circuit board (eg, the first printed circuit board 480 of FIG. 4 ) may be disposed under the speaker 580 and the battery 470 . The first printed circuit board 480 includes a processor (eg, processor 120 in FIG. 1 ), a memory (eg, memory 130 in FIG. 1 ), and/or an interface (eg, interface 177 in FIG. 1 ). Electronic components (or components) such as may be mounted (or mounted). A first shielding agent 560 may be disposed under the first printed circuit board 480 . A first shielding agent 560 may be included to reduce the effect of magnetic force by the magnet 520 . A magnet 520 may be disposed under the first shielding agent 560 .

The magnet 520 may be disposed on the rear surface of the housing 210 of the electronic device 200 (eg, the rear plate 493 of FIG. 4 ). For example, the electronic device 200 including the circular housing 210 may include the circular magnet 520 . For example, the magnet 520 may include a first magnet 521 and a second magnet 525 . The first magnet 521 may be disposed under the first shielding material 560 , and a second printed circuit board 540 may be included between the first magnet 521 and the second magnet 525 . At least one of the first magnet 521 and the second magnet 525 may have a characteristic in which magnetic force strength is reduced in a specific direction (eg, a vertical direction) in which the geomagnetic sensor 515 is located. For example, since the first magnet 521 may exert more magnetic force influence on the geomagnetic sensor 515 than the second magnet 525 , the first magnet 521 has a characteristic that the magnetic force strength is reduced in a specific direction. , the second magnet 525 may be used as a general magnet. Alternatively, both the first magnet 521 and the second magnet 525 may have a characteristic in which magnetic force strength is reduced in a specific direction.

The second printed circuit board 540 may include a sensor module (eg, the sensor module 176 of FIG. 1 ) and the sensor module 211 of FIG. 2 . The sensor module 211 may include a light emitting unit 571 and a light receiving unit 573 . According to various embodiments, the sensor module 211 may be a photoplethysmography (PPG) sensor capable of detecting a biosignal related to a user's heartbeat. In addition, the sensor module 211 may include sensors for detecting various biosignals.

The second magnet 525 may have a shape (eg, a donut shape) in which a hole is drilled in the center. The light emitting part 571 of the sensor module 211 may be disposed in the hole (eg, inside the second magnet 525 ), and the light receiving part 573 may be disposed outside the second magnet 525 . The light emitting unit 571 may be an element capable of emitting light, such as a light emitting diode (LED) or an organic light emitting diode (OLED). In addition, the light emitting unit 571 may be composed of various elements capable of emitting light. One or more light receiving units 573 may be included around the light emitting units 571 . For example, the light receiving unit 573 may be a light receiving element that converts light energy into electrical energy. For example, the light receiving unit 573 may include a photodiode.

According to various embodiments, the sensor module 211 may use a difference in optical response according to oxygen saturation of hemoglobin in blood. The light provided from the light emitting unit 571 may be transmitted to the user's body, and the light receiving unit 573 may receive reflected light of the light transmitted to the body. The reflected light received by the light receiving unit 573 has periodicity due to a difference in optical response according to the oxygen saturation of hemoglobin described above. The sensor module 550 may detect a signal related to the user's heartbeat by using this periodicity. In some cases, a sensor (eg, an acceleration sensor, a gyro sensor) that detects the position of the electronic device 200 may indirectly measure a user's movement, and a heartbeat-related signal may be more precisely processed through this movement information. . The biosignal detection of the sensor module 221 described above describes a representative principle of detecting heartbeat-related information using the light emitting unit 571 and the light receiving unit 573 , and the sensor module 211 according to various embodiments disclosed in this document. ) can detect the user's heartbeat-related information as a biosignal in various other ways.

As described above, the sensor module 221 may utilize a phenomenon in which the light generated by the light emitting unit 571 is reflected by the user's body and is received by the light receiving unit 573 . In order to accurately and precisely detect a biosignal, it may be desirable to suppress a phenomenon in which the light generated from the light emitting unit 571 is not reflected by the body and transmitted to the light receiving unit 573 . For example, the second magnet 525 may serve as a barrier rib that blocks (or suppresses) light generated from the light emitting unit 571 from being transmitted to the light receiving unit 573 . Since the second magnet 525 is formed in a donut shape with a hole in the middle, the light emitting part 571 is disposed inside the second magnet 525 and the light receiving part 573 is disposed outside the second magnet 525 . By doing so, the second magnet 525 may serve as a partition wall. In addition, the second magnet 525 may also serve to strengthen the tensile force with the wireless charging pad.

According to various embodiments, the polarities of the surfaces of the first magnet 521 and the second magnet 525 facing each other may be opposite. For example, the first magnet 521 forms a surface (eg, a lower surface) facing the second printed circuit board 540 as an S pole, and a surface opposite to the second printed circuit board 540 (eg: upper surface) may be formed as an N pole. The second magnet 525 forms a surface (eg, an upper surface) facing the second printed circuit board 540 as an N pole, and a surface (eg, a lower surface) facing the rear of the housing 210 as an S pole can be formed
