[0042] FIG. 5 is a view of an electronic device from the front after removing the display of the electronic device according to one embodiment of the present disclosure.

[0043] FIG. 6 is a schematic diagram showing a cross-section of the electronic device of FIG. 2b cut in the C1-C2 direction according to one embodiment of the present disclosure.

[0044] FIG. 7a is a drawing showing the value of the H-field measured in area A of FIG. 2a for an electronic device according to one embodiment of the present disclosure when there is no front shielding sheet and no rear shielding sheet.

[0045] Figure 7b is a diagram classifying the H-field measured in Figure 7a according to the magnetic force criteria under the hearing aid compatibility (HAC) regulations of the Federal Communications Commission (FCC).

[0046] FIG. 7c is a drawing showing the value of the H-field measured in area A of FIG. 2a for an electronic device according to one embodiment of the present disclosure when only a front shielding sheet is present.

[0047] Figure 7d is a diagram classifying the H-field measured in Figure 7c according to the magnetic force criteria under the FCC HAC regulations.

[0048] FIG. 7e is a drawing showing the H-field measured in area A of FIG. 2a for an electronic device (100) including a front shielding sheet and a rear shielding sheet including a slit according to one embodiment of the present disclosure.

[0049] Figure 7f is a diagram classifying the H-field measured in Figure 7e according to the magnetic force criteria under the FCC HAC regulations.

[0050] FIG. 7g is a drawing showing the H-field measured in area A of FIG. 2a for an electronic device including a front shielding sheet and a rear shielding sheet including an opening according to one embodiment of the present disclosure.

[0051] Figure 7h is a diagram classifying the H-field measured in Figure 7g according to the magnetic force criteria under the FCC HAC regulations.

[0052] Recently, as communication protocols (e.g., UL MIMO (uplink multiple input multiple output), 2TX (transmitter)) are applied to increase data traffic and expand coverage, the current consumed in RF (radio frequency) circuits has increased, making it difficult to meet the H-field standards of HAC.

[0053] As the number of electronic devices adopting NFC (near field communication) or wireless charging circuits increases, a shielding layer having high permeability characteristics to block the magnetic field generated by the NFC or wireless charging circuit is placed near the RF circuit of the electronic device.

[0054] High-permeability shielding layers placed near RF circuits are easily magnetized, which presents a problem where the magnetic field is concentrated near the speaker (e.g., receiver) rather than being emitted externally through the cover of the electronic device.

[0055] An electronic device including a shielding structure according to one embodiment of the present disclosure may form an opening or a slit by removing a portion of the shielding layer corresponding to the area where the RF circuit or wiring and the coil overlap, in order to solve the problem of the magnetic field emitted from the RF circuit not being emitted to the outside by shielding the entire area where the RF circuit or wiring and the coil overlap.

[0056] An electronic device including a shielding structure according to one embodiment of the present disclosure can direct a magnetic field emitted from an RF circuit to the outside of the electronic device by removing a portion corresponding to an area where an RF circuit or wiring and a coil overlap in the shielding layer or by forming a slit.

For example, the one or more storage media may include a hard drive, a permanent memory such as flash memory, read-only memory (ROM) (e.g., non-volatile memory (122)), a semi-permanent memory such as random access memory (RAM) (e.g., volatile memory (121)), any other suitable type of storage (or storage assembly), or any combination thereof. Memory (120) may include a cache memory, which is one or more different types of memory used to temporarily store data for a function or feature of the electronic device (100).

The hearing aid may include a device located outside the electronic device (100). However, it is not limited thereto, and the hearing aid may include a device integrated with the electronic device (100).

[0071] In one embodiment, when an external electronic device (e.g., a hearing aid) is connected to a terminal and used for a call, instructions, when executed individually or collectively by at least one processor (110), may cause the electronic device (100) to request a base station or network to limit the application of uplink (UL) MIMO (multiple input multiple output).

[0148] Figure 7b is a diagram classifying the H-field measured in Figure 7a according to the magnetic force criteria under the hearing aid compatibility (HAC) regulations of the Federal Communications Commission (FCC).

[0149] Referring to FIGS. 2a, FIGS. 7a, and FIGS. 7b, in the graphs of FIGS. 7a and FIGS. 7b, the x-axis represents the vertical direction of area A (e.g., refer to FIG. 2a), and the y-axis represents the horizontal direction of area A. The units of the x-axis and y-axis may include meters (m).

[0150] Referring to FIGS. 7a and 7b, the index (710) representing the magnetic force strength may indicate that the magnetic force becomes weaker as the lightness decreases. In one embodiment, when the x value in region A is 0 to 0.02 (m), it represents a part of the electronic device (100) in the first edge region (201) of the electronic device (100), and when the x value is 0 to -0.02 (m), it represents an outer region of the electronic device (100) in the first edge region (201).

[0151] In one embodiment, the magnetic force criterion according to the FCC HAC regulation is -38 dBA / m or less. By checking the magnetic force for specific points in area A, if 300 or more points have a magnetic force of -38 dBA / m or less, it can pass the FCC HAC regulation. For example, each of the clustered squares included in FIG. 7b can be determined as a single point. However, the FCC HAC passing regulation is not limited to 300 points, and the total number of points may change according to the FCC HAC passing regulation.

[0159] Referring to FIG. 7c and FIG. 7d, the index (710) representing the magnetic force strength may indicate that the magnetic force becomes weaker as the lightness decreases. In one embodiment, when the x value in region A is 0 to 0.02 (m), it represents a part of the electronic device (100) in the first edge region (201) of the electronic device (100), and when the x value is 0 to -0.02 (m), it represents an outer region of the electronic device (100) in the first edge region (201).

[0160] FIG. 7d shows a pass point (701) in which the magnetic force in area A is -38 dBA / m or less and a fail point (702) in which the magnetic force exceeds -38 dBA / m through the FCC’s HAC regulation test, and in the case of only the front shielding sheet (410), there may be 274 pass points (701).

[0161] In this case, the number of passing points (701) is improved compared to when there are no front shielding sheets (410) and rear shielding sheets (350), but it is still difficult to pass the FCC’s HAC regulations.

[0162] FIG. 7e is a drawing showing the H-field measured in area A of FIG. 2a for an electronic device (100) including a front shielding sheet (410) and a rear shielding sheet (350) including a slit (351) according to one embodiment of the present disclosure.

The units of the x-axis and y-axis may include meters (m). Referring to FIGS. 7e and FIGS. 7f, the index (710) representing the magnetic force strength may indicate that the magnetic force becomes weaker as the lightness decreases.

[0165] In one embodiment, when the x value in area A is 0 to 0.02 (m), it represents a part of the electronic device (100) in the first edge region (201) of the electronic device (100), and when the x value is 0 to -0.02 (m), it may represent an outer region of the electronic device (100) in the first edge region (201).

[0166] FIG. 7e shows a pass point (701) in which the magnetic force in area A is -38 dBA / m or less and a fail point (702) in which the magnetic force exceeds -38 dBA / m through the FCC HAC regulation test, and when including a front shielding sheet (410) and a rear shielding sheet (350) including a slit (351), there may be 430 pass points (701). In this case, it can pass the FCC HAC regulation.

[0167] FIG. 7g is a drawing showing the H-field measured in area A of FIG. 2a for an electronic device (100) including a front shielding sheet (410) and a rear shielding sheet (350) including an opening (352) according to one embodiment of the present disclosure.
