According to an embodiment, the electronic device 101 may communicate with the electronic device 104 via the server 108. According to an embodiment, the electronic device 101 may include a processor 120, a memory 130, an input module 150, a sound output module 155, a display module 160, an audio module 170, a sensor module 176, an interface 177, a connection terminal 178, a haptic module 179, a camera module 180, a power management module 188, a battery 189, a communication module 190, a user identification module (SIM) 196, or an antenna module 197. In some embodiments, at least one of the components (e.g., the connection terminal 178) may be omitted from the electronic device 101, or one or more other components may be added to the electronic device 101. In some embodiments, some of the components (e.g., sensor module 176, camera module 180, or antenna module 197) may be implemented as a single component (e.g., display module 160). The processor 120 may run, for example, software (e.g., program 140) to control at least one other component (e.g., hardware component or software component) of the electronic device 101 connected to the processor 120, and may perform a data processing or calculation. According to an embodiment, as at least part of the data processing or calculation, the processor 120 may store a command or data received from another component (e.g., sensor module 176 or communication module 190) in the volatile memory 132, process the command or data stored in the volatile memory 132, and store the result data in the non-volatile memory 134.

The communication module 190 may include one or more communication processors capable of operating independently from the processor 120 (e.g., an application processor (AP)) and supporting direct (e.g., wired) communication or wireless communication. According to an embodiment, the communication module 190 may include a wireless communication module 192 (e.g., a cellular communication module, a short-range wireless communication module, or a global navigation satellite system (GNSS) communication module) or a wired communication module 194 (e.g., a local area network (LAN) communication module or a power line communication (PLC) module). A corresponding one of these communication modules may communicate via a first network 198 (e.g., a short-range communication network such as Bluetooth TM , Wireless Fidelity (Wi-Fi) Direct, or Infrared Data Association (IrDA)) or a second network 199 (for example, a long-distance communication network such as a traditional cellular network, a 5G network, a next-generation communication network, the Internet, or a computer network (for example, a LAN or a wide area network (WAN)))) to communicate with an external electronic device. These various types of communication modules can be implemented as a single component (for example, a single chip), or these various types of communication modules can be implemented as multiple components separated from each other (for example, multiple chips). The wireless communication module 192 can use user information (for example, an International Mobile Subscriber Identity (IMSI)) stored in the user identification module 196 to identify and authenticate the electronic device 101 in a communication network (such as the first network 198 or the second network 199).

[0112] According to the embodiment, referring to Figure 6a , the FPCB 520 may be electrically connected to the battery 510 and disposed to surround at least a portion of a side surface of the battery 510. For example, the solder of the FPCB 520 may be electrically connected to the cathode tab 515 and the anode tab 514 of the battery 510. According to an embodiment, the main PCB 540 may be disposed on the battery 510 (e.g., at Figure 6ain the +Z direction) and is electrically connected to the FPCB 520.

[0113] According to the embodiment, referring to Figures 6a to 6e , the FPCB 520 may surround at least a portion of the battery 510. The FPCB 520 may be disposed to surround at least a portion of the speaker 530. For example, the FPCB 520 may be disposed in a third direction (eg, Figure 6a The FPCB 520 surrounds the battery 510 and the speaker 530 in the Z-axis direction in FIG. 5. An end of the FPCB 520 may be connected to the main PCB 540.

[0114] According to an embodiment, the FPCB 520 may include a power wiring 521 (VBAT) electrically connected to the anode 511 of the battery 510 , a ground wiring 522 (GND) electrically connected to the cathode 512 , and a signal wiring (not shown).

[0115] According to an embodiment, the current may flow as follows: The current may flow from the anode 511 of the battery 510 to the power wiring 521 of the FPCB 520 through the anode terminal tab 514 connected to the anode 511, flow from the power wiring 521 of the FPCB 520 to the ground wiring 522 of the FPCB 520, and flow to the cathode terminal tab 515 and the cathode 512 of the battery 510 through the ground wiring 522 of the FPCB 520. For example, current can flow from the anode 511 of the battery 510 to the power wiring 521 of the FPCB 520 through the anode terminal tab 514 connected to the anode 511, from the power wiring 521 of the FPCB 520 to the main PCB 540 (main PBA), and from the main PCB 540 (main PBA) to the ground wiring 522 of the FPCB 520, from the ground wiring 522 of the FPCB 520 to the battery protection circuit module integrated circuit (PCM IC), and through the battery PCM IC to the cathode terminal tab 515 and the cathode 512 of the battery 510.

[0116] According to an embodiment, the speaker 530 may be disposed close to the battery 510. For example, the speaker 530 may be stacked with the battery 510. For example, the speaker 530 may be disposed coaxially with the battery 510. For example, the central axis of the speaker 530 and the central axis of the battery 510 may be disposed close to each other or coincide with each other. However, the arrangement and position of the speaker 530 are not limited to the above-mentioned embodiments, and various design modifications may be made depending on the size or arrangement relationship of the surrounding structure.

[0117] According to an embodiment, the anode 511 and the cathode 512 of the battery 510 may have different lengths. The length of the anode 511 may be a first length (e.g., the length from the central axis of the battery 510 to the anode tab 514), and the length of the cathode 512 may be a second length different from the first length (e.g., the length from the central axis of the battery 510 to the cathode tab 515). The length difference between the anode 511 and the cathode 512 may be a third length l3. According to an embodiment, the second length may be greater than the first length. The second length may be a third length l3 greater than the first length. According to an embodiment, the first length may be greater than the second length. However, the lengths of the anode 511 and the cathode 512 are not limited to the lengths of the above-described embodiments, and many design modifications may be made according to the design method.

[0118] According to an embodiment, a first magnetic field may be formed by the anode 511, and a second magnetic field may be formed by the cathode 512 in a direction opposite to the direction of the first magnetic field. Since the anode 511 and the cathode 512 are wound overlapping each other, the magnetic fields may be offset in a section where the anode 511 and the cathode 512 overlap.

[0119] According to the embodiment, referring to Figure 8b , because the lengths of the anode 511 and the cathode 512 are different, the first current formed to flow along the first winding direction ① may flow in the battery 510 due to the length difference between the cathode 512 and the anode 511. The third magnetic field may be formed by the first current. For example, when the second length (not shown) of the cathode 512 is greater than the first length (not shown) of the anode 511, the third magnetic field may be formed by the longer portion of the cathode 512 based on the negative current. When the first current is a negative current, the first winding direction ① may be opposite to the winding direction of the anode 511, the cathode 512, and the separator 513. For example, when the winding direction of the anode 511, the cathode 512, and the separator 513 is clockwise, the first winding direction ① may be counterclockwise. For example, when the winding direction of the battery 510 is counterclockwise, the first winding direction ① may be clockwise.

[0120] In general, the third magnetic field generated by the length difference between the cathode 512 and the anode 511 can affect the nearby speaker 530. For example, a current can be induced in the coil of the speaker 530 included in the speaker 530 by the third magnetic field, and the current can affect the vibration of the diaphragm of the speaker 530, thereby generating noise (e.g., electromagnetic field). For example, periodic noise can occur due to peak current.

[0121] According to an embodiment, a pure iron sheet may be applied between the battery 510 and the speaker 530 to prevent noise. According to an embodiment, an eccentric design may be applied to the arrangement of the speaker 530 and the battery 510 to prevent noise.

[0122] According to an embodiment, the present disclosure can effectively mitigate or remove noise using at least one wiring of the FPCB 520 through which a second current flows, the second current being formed to flow in a second winding direction ② opposite to a first winding direction ① in which the first current flows. This will be described later.

The ground wiring 522 may be formed of a plurality of thin wirings. When the position where the power wiring 521 of the FPCB 520 is set is briefly shown in the drawings and the remaining part is defined as the position where the ground wiring 522 is set, the power wiring 521 may be set closer to the speaker 530 than the ground wiring 522.

[0132] According to an embodiment, the first region 520a of the FPCB 520 may be a region including solder directly connected to the battery 510. The solder of the FPCB 520 may be electrically connected to the cathode tab 515 and the anode tab 514 of the battery 510. The first region 520a may be in a shape surrounding at least a portion of a side surface of the battery 510.

[0133] According to an embodiment, the second region 520b of the FPCB 520 may be a region electrically connected to the main PCB 540. An end of the second region 520b may contact the main PCB 540.

[0134] According to an embodiment, the third region 520c of the FPCB 520 may contact at least a portion of the side surface of the battery 510 and the speaker 530. The wiring arrangement of the third region 520c may determine the direction of the magnetic field and affect noise generation. Figure 9a and Figure 9b In the third region 520c, the power supply wiring 521 may be arranged in a downward direction (eg, Figure 9b The ground wiring 522 may be arranged in an upward direction (eg, Figure 9b According to the embodiment, refer to Fig.10a and Fig.10b In the third region 520c, the power supply wiring 521 may be arranged in an upward direction (eg, Figure 9b The ground wiring 522 may be arranged in the downward direction (eg, Figure 9b The following describes different magnetic field directions and different noises according to the wiring positions.

[0135] According to an embodiment, the second current flowing through the ground wiring 522 of the FPCB 520 may flow in the opposite direction to the first current of the battery 510. The third current flowing through the power wiring 521 of the FPCB 520 may flow in the same direction as the first current of the battery 510 (see Figure 9d ). For example, when the first winding direction ① is counterclockwise, the second winding direction ② may be clockwise, and the third winding direction ③ may be counterclockwise.

[0136] According to an embodiment, the current flowing in the wiring disposed closer to the speaker 530 among the power wiring 521 and the ground wiring 522 of the FPCB 520 may flow in the same direction as the first current of the battery 510. Fig.9c and Figure 9d , the third current flowing through the power wiring 521 disposed closer to the speaker 530 among the power wiring 521 and the ground wiring 522 of the FPCB 520 may flow in the same direction as the first current of the battery 510. The second current flowing in the ground wiring 522 disposed farther from the speaker 530 among the power wiring 521 and the ground wiring 522 of the FPCB 520 may flow in the opposite direction to the first current of the battery 510. For example, referring to Fig.9c and Figure 9d , the first winding direction ① of the first current flowing through the battery 510 may be counterclockwise, the second winding direction ② of the second current flowing through the ground wiring 522 relatively spaced apart from the speaker 530 may be clockwise, and the third winding direction ③ of the third current flowing through the power wiring 521 disposed relatively close to the speaker 530 may be counterclockwise. However, the directions of the currents flowing through the battery 510 and the power wiring 521 and the ground wiring 522 of the FPCB 520 are not limited to the above-described embodiments, and various design modifications may be made through the shape, arrangement relationship, and / or structure of the electronic device 500.

[0137] According to the embodiment, since the power wiring 521 of the FPCB 520 through which the current flows in the same direction as the first current of the battery 510 is disposed closer to the speaker 530, the magnetic field lines M of the FPCB 520 may be formed to face, for example, Fig.9c The magnetic force lines M of the FPCB 520 may be the sum of the magnetic force m1 formed by the power wiring 521 and the magnetic force m2 formed by the ground wiring 522. At least a portion of the magnetic force m1 formed by the power wiring 521 of the FPCB 520 may penetrate at least a portion of the speaker 530 in the upward direction F. At least a portion of the magnetic force m1 formed by the power wiring 521 may, for example, Fig.9c At least a portion of the speaker 530 is penetrated between the -X direction and the +Z direction. As a result, noise may occur.

[0138] According to the embodiment, referring to Fig.9e , the peak noise level generated by the magnetic field of the FPCB 520 may be -97dB at 1.6kHz.

[0139] According to the embodiment, referring to Fig.10a and Fig.10b, when the position where the power wiring 521 of the FPCB 520 is set is briefly shown in the drawing and the remaining portion is defined as the position where the ground wiring 522 is set, the ground wiring 522 can be set closer to the speaker 530 than the power wiring 521.

[0140] According to an embodiment, the current flowing in the wiring (eg, the ground wiring 522) disposed closer to the speaker 530 among the power wiring 521 and the ground wiring 522 of the FPCB 520 may flow in the opposite direction to the first current of the battery 510. Fig.10c and Fig.10d , the second current flowing through the ground wiring 522 disposed closer to the speaker 530 among the power wiring 521 and the ground wiring 522 of the FPCB 520 may flow in the opposite direction to the first current of the battery 510. The third current flowing in the power wiring 521 disposed farther from the speaker 530 among the power wiring 521 and the ground wiring 522 of the FPCB 520 may flow in the same direction as the first current of the battery 510. For example, referring to Fig.10c and Fig.10d The first winding direction ① of the first current flowing through the battery 510 can be counterclockwise, the second winding direction ② of the second current flowing through the ground wiring 522 set relatively close to the speaker 530 can be clockwise, and the third winding direction ③ of the third current flowing through the power wiring 521 set relatively far from the speaker 530 can be counterclockwise.

[0141] According to the embodiment, since the ground wiring 522 of the FPCB 520 through which the current flows in the opposite direction to the first current of the battery 510 is disposed closer to the speaker 530, the magnetic field lines M of the FPCB 520 may be formed to face, for example, Fig.10c The magnetic force lines M of the FPCB 520 may be the sum of the magnetic force m1 formed by the power wiring 521 and the magnetic force m2 formed by the ground wiring 522. Although the magnetic force m2 formed by the ground wiring 522 of the FPCB 520 may penetrate at least a portion of the speaker 530, this may be offset due to the opposite direction to the third magnetic field formed by the battery 510. Therefore, noise may be reduced or eliminated.

[0142] According to the embodiment, referring to Fig.10e , the peak noise level generated by the magnetic field of the FPCB 520 may be -104 dB at 1.6 kHz. It can be noted that compared with the noise ( Fig.9e ), the noise value is reduced.

[0143] It can be noted that when the ground wiring 522 formed to allow the second current to flow in the second winding direction ② opposite to the first winding direction ① is disposed closer to the speaker 530, compared with the corresponding embodiments (for example, Figures 9a to 9e and Figures 10a to 10e ), the noise value is reduced.
