[0077] According to one embodiment, the second substrate (622) may extend parallel to the second circuit area (602) from the third circuit area (703) of the first substrate (621). At least a portion of the second substrate (622) may extend perpendicularly to the third circuit area (703) of the first substrate (621).

[0078] A plurality of signal lines (801, 802, 803) configured to transmit digital electrical signals may be disposed on the second substrate (622). At least one of the plurality of signal lines (801, 802, 803) may allow a digital electrical signal to flow between the internal configuration of the key circuit board (620) and the configuration disposed on the printed circuit board (710). At least one of the plurality of signal lines (801, 802, 803) may be composed of a conductive material.

[0079] According to one embodiment, a plurality of signal lines (801, 802, 803) may include a first signal line (801), a second signal line (802), and a third signal line (803) corresponding to ground.

The third signal line (803) can be connected to the ground of the printed circuit board (710).

[0080] According to one embodiment, the first signal line (801), the second signal line (802), and the third signal line (803) may be configured to transmit information signals independently of each other. For example, the first signal line (801) may be configured to transmit a first digital input signal (or a discrete digital signal) in digital form to a printed circuit board through a first connection terminal (641). The second signal line (802) may be configured to transmit a second digital input signal (or a discrete digital signal) to a printed circuit board through a second connection terminal (642). The third signal line (803) may be connected to the ground of the printed circuit board (710).

[0081] According to one embodiment, a first switch (611) connected to a first signal line (801) can acquire a first digital input signal. For example, when the first switch (611) is pressed by a user's pressing action (or contact action, pressure action, click action), the first switch (611) can generate (or acquire) a first digital input signal of high logic (or logic value 1). When the first switch (611) is not pressed, the first switch (611) can acquire a first digital input signal of low logic (or logic value 0). The acquired first digital input signal can be transmitted to a first circuit area (701) of a key circuit board (620) through the first switch (611). The first switch (611) can transmit a first digital input signal to the first signal line (801) of the key circuit board (620) by physically contacting the first circuit area (701) of the key circuit board (620) by the pressing (or pressing) operation of the key member (630). A processor (e.g., processor (110) of FIG. 1) placed on a printed circuit board (710) electrically connected to the key circuit board (620) can perform the function of an electronic device corresponding to the first digital input signal received through the first signal line (801) of the key circuit board (620). For example, the processor can perform a volume up function to increase the volume of the electronic device in response to the first digital input signal of high logic. For example, the processor may not perform a volume up function to increase the volume of the electronic device in response to the first digital input signal of low logic.

[0082] According to one embodiment, a second switch (612) connected to a second signal line (802) can acquire a second digital input signal. For example, when the second switch (612) is pressed by a user's pressing action (or contact action, pressure action, click action), the second switch (612) can generate (or acquire) a second digital input signal of high logic (or logic value 1). When the second switch (612) is not pressed, the second switch (612) can acquire a second digital input signal of low logic (or logic value 0). The acquired second digital input signal can be transmitted to a second circuit area (702) of a key circuit board (620) through the second switch (612). The second switch (612) can transmit a second digital input signal to the second signal line (802) of the key circuit board (620) by physically contacting the second circuit area (702) of the key circuit board (620) through the pressing (or pressing) operation of the key member (630). A processor (e.g., processor (110) of FIG. 1) placed on a printed circuit board (710) electrically connected to the key circuit board (620) can perform the function of an electronic device corresponding to the second digital input signal received through the second signal line (802) of the key circuit board (620). For example, the processor can perform a volume down function to lower the volume of the electronic device in response to a second digital input signal of high logic. For example, the processor may not perform a volume down function to lower the volume of the electronic device in response to a second digital input signal of low logic.

For example, at least one first passive element (810) may be disposed between the first signal line (801) and the second signal line (802). One end of the at least one first passive element (810) may be electrically connected to the first signal line (801), and the other end of the at least one first passive element (810) may be electrically connected to the second signal line (802). For example, at least one first passive element (810) may be arranged in a parallel and / or serial form between the first signal line (801) and the second signal line (802). When at least one first passive element (810) is arranged in a plurality, the first passive element (810) may have different element values. According to one embodiment, the element value of at least one first passive element (810) may vary depending on the frequency band of the antenna radiator when the first conductive part (e.g., the first conductive part (511) of FIG. 6) that generates coupling with the key circuit board (620) operates as an antenna radiator.

[0084] According to one embodiment, at least one first passive element (810) may be formed as a capacitor and / or an inductor. For example, even if the first passive element (810) is formed as a capacitor with a low thickness (or height) due to mounting space constraints of the key structure (601), the first passive element (810) can secure performance without degradation and secure high strength. The first passive element (810) placed on the second substrate (622) may be formed to have a thickness smaller than the distance between the second substrate (622) and the printed circuit board (710).

[0085] According to one embodiment, at least one first passive element (810) can form an electrical connection path between the first signal line (801) and the second signal line (802). The first signal line (801) and the second signal line (802) can act as a short circuit through the first passive element (810) in the frequency domain of the first conductive part (511) used as an antenna radiator. When RF resonance occurs in the frequency domain of the first conductive part (511) used as an antenna radiator, the key structure (601) can be electrically isolated from the first conductive part (511). Parasitic resonance components generated due to coupling between the key circuit board (620) containing the first signal line (801) and the first conductive part (511) used as an antenna radiator can be reduced or eliminated. The parasitic resonance structure between the key structure (601) and the first conductive part (511) operating as an antenna radiator can be destroyed. The radiation performance of the first conductive part (511) operating as an antenna radiator adjacent to the key structure (601) can be improved or enhanced.

For example, at least one second passive element (1010) may be disposed in a parallel and / or serial form between the second signal line (802) and the third signal line (803). When at least one second passive element (1010) is disposed in multiple numbers, the second passive elements (1010) may have different element values. According to one embodiment, the element value of at least one second passive element (1010) may vary depending on the frequency band of the antenna radiator when the first conductive part (e.g., the first conductive part (511) of FIG. 6) that generates coupling with the key circuit board (620) operates as an antenna radiator.

[0094] According to one embodiment, at least one of at least one first passive element (810) and at least one second passive element (1010) may be formed as a capacitor and / or an inductor. For example, at least one first passive element (810) may be formed as at least one capacitor, and at least one second passive element (1010) may be formed as at least one capacitor. For example, at least one first passive element (810) may be formed as at least one capacitor, and at least one second passive element (1010) may be formed as at least one inductor. For example, at least one first passive element (810) may be formed as at least one inductor, and at least one second passive element (1010) may be formed as at least one capacitor. According to one embodiment, even if the first passive element (810) and the second passive element (1010) are formed with a low-height capacitor due to the mounting space constraints of the key structure (601), performance can be secured without degradation and high strength can be secured.

[0095] According to one embodiment, at least one first passive element (810) can form an electrical connection path between the first signal line (801) and the second signal line (802). At least one second passive element (820) can form an electrical connection path between the second signal line (802) and the third signal line (803).

[0096] According to one embodiment, the first signal line (801) and the second signal line (802) can act as a short circuit through the first passive element (810) in the frequency domain of the first conductive part (511) used as an antenna radiator. When RF resonance occurs in the frequency domain of the first conductive part (511) used as an antenna radiator, the key structure (601) can be electrically isolated from the first conductive part (511). Parasitic resonance components generated due to coupling between the key circuit board (620) containing the first signal line (801) and the first conductive part (511) used as an antenna radiator can be reduced or eliminated. The parasitic resonance structure between the key structure (601) and the first conductive part (511) operating as an antenna radiator can be destroyed. The radiation performance of the first conductive part (511) that operates as an antenna radiator while adjacent to the key structure (601) can be improved or enhanced.
