[0088] Reference Figure 6a The electronic device according to one embodiment can be similar to Figures 1a to 1c Electronic device 101. Figure 6a The embodiments may further include a foreign object prevention component 657.

[0089] According to one embodiment, with reference to the Z-axis, a foreign object prevention member 657 can be positioned (decorated) between the housing 110 and the second surface of the second first printed circuit board 152-1 (e.g., in the +Z direction), thus preventing foreign objects from being introduced into the interior of the housing 110. The foreign object prevention member 657 can be located in a recess (or depression) 110-1, which is formed by removing (thinning) a portion of the housing 110 that contacts the second surface of the second first printed circuit board 152-1. According to one embodiment, the depression 110-1 can have a shape similar to or different from the first microphone hole 111, and can be smaller than a portion of the housing 110 that is larger than the first microphone hole 111 and contacts the second surface of the second first printed circuit board 152-1. According to another embodiment, the depression 110-1 can have dimensions in which the second surface of the second first printed circuit board 152-1 can be positioned. For example, the second first printed circuit board 152-1 can be located in the depression 110-1.

[0090] According to one embodiment, the foreign object prevention member 657 may be conductive and can be used as a touch electrode. The foreign object prevention member 657 may be configured to operate like a capacitor by being spaced a predetermined distance from the first touch electrode 152b-1. According to one embodiment, the first touch electrode 152b-1 and the foreign object prevention member 657 may be electrically connected to each other via separate components (not shown) or directly. Although not shown, according to one embodiment, a reinforcing member 355 may be located between the first touch electrode 152b-1 and the foreign object prevention member 657. For example, the first touch electrode 152b-1, the reinforcing member 355, and the foreign object prevention member 657 may be electrically connected to each other. When the foreign object prevention member 657 is conductive, the electronic device can reduce the distance d between the housing 110 and the foreign object prevention member 657, thereby improving touch sensitivity.

[0091] According to one embodiment, the foreign object prevention member 657 and the first touch electrode 152b-1 may comprise the same material, or at least a portion of the foreign object prevention member 657 and the first touch electrode 152b-1 may comprise different materials. For example, the foreign object prevention member 657 and the first touch electrode 152b-1 may comprise the same material (e.g., copper) or different materials (e.g., at least one of copper, silver, gold, or aluminum). The foreign object prevention member 657 may be a conductive mesh.

[0096] Reference Figure 7a The electronic device according to one embodiment can be similar to Figures 1a to 1c Electronic device 101. Figure 7a The electronic device may further include sound insulation components (or sound leakage prevention components) 759.

[0097] According to one embodiment, a sound-insulating member 759 may be positioned (set) about the Z-axis in at least a portion of the space between the second first printed circuit board 152-1 and the housing 110 to fill the gap between the housing 110 and the second first printed circuit board 152-1 and form an audio path to prevent external sound introduced through the first microphone hole 111 from diffusing into the interior of the housing 110 and to allow external sound to be transmitted to the first microphone 141 through the second first microphone hole 152a-1. The sound-insulating member 759 may be located in a recess (or depression) 110-1 configured by removing (e.g., thinning) a portion of the housing 110 that contacts the second surface of the second first printed circuit board 152. The recess 110-1 may be surrounded by at least a portion of the second first printed circuit board 152-1.

[0098] According to one embodiment, the sound-insulating member 759 may be conductive and can be used as a touch electrode. For example, the sound-insulating member 759 may be conductive rubber. The sound-insulating member 759 may contact the first touch electrode 152b-1 for electrical connection thereto. When the sound-insulating member 759 is conductive, the electronic device can reduce the distance between the touch electrode (e.g., the sound-insulating member 759) and the user's finger in contact with the housing 110, thereby improving touch sensitivity.

[0099] Although not shown, according to one embodiment, the reinforcement 355 and / or the foreign object prevention member 657 may be located between the sound insulation member 795 and the first touch electrode 152b-1. For example, the sound insulation member 795, the reinforcement 355, the foreign object prevention member, and the first touch electrode 152b-1 may be electrically connected. According to one embodiment, the reinforcement 355 may be located between the sound insulation member 795 and the first touch electrode 152b-1, and the foreign object prevention member 657 may be located between the sound insulation member 765 and the housing 110.

[0100] Although not shown, according to one embodiment, a conductive pattern may be located around the first microphone hole 111 of the housing 110. For example, a conductive pattern electrically connected to the sound insulation member 759 may be located on the portion of the housing 110 containing the first microphone hole 111 or on the inner surface of the portion of the housing 110 containing the first microphone hole 111. Electronic devices may electrically connect the sound insulation member 759, the first touch electrode 152b-1, and / or the conductive pattern located on the inner surface of the housing 110 to improve touch sensitivity.

[0101] Although Figure 7a It has been shown that the sound insulation component 759 is installed in Figures 1a to 1c The example in electronic device 101 is for illustrative purposes only. Figure 7a The sound insulation component 759 can be applied in the same or similar way to Figures 1d to 3b Electronic devices 102, 201, 202, 301 and 302.

[0102] Figure 7b This is a view illustrating an electronic device including a foreign object prevention member and a sound insulation member according to another embodiment.

[0103] Reference Figure 7b The electronic device according to another embodiment can be similar to Figures 1a to 1c Electronic device 101. Regarding the Z-axis, Figure 7bThe electronic device may include a sound-insulating member 759 and a foreign object prevention member 657 between the second first printed circuit board 152-1 and the housing 110. For example, the sound-insulating member 759 and the foreign object prevention member 657 may be stacked on a second surface (e.g., in the +Z direction) of the second first printed circuit board 152-1 on which the first first touch electrode 152b-1 is located. The sound-insulating member 759 and the foreign object prevention member 657 may be located in a recess (or depression) 110-1, which is formed by removing (e.g., thinning) a portion of the housing 110 that contacts the second surface of the second first printed circuit board 152-1. The recess 110-1 may be surrounded by at least a portion of the second first printed circuit board 152-1.

[0104] According to one embodiment, the sound-insulating member 759 and the foreign object prevention member 657 may be conductive. An electronic device may electrically connect the first touch electrode 152b-1, the sound-insulating member 759, and the foreign object prevention member 657, thereby improving touch sensitivity.

[0105] Although Figure 7b The sound insulation component 759 and the foreign object prevention component 657 have been shown arranged in Figures 1a to 1c The structure in the electronic device 101 is shown as an example, but this is only for illustrative purposes. Figure 7b The sound insulation component 759 and the foreign object prevention component 657 can be applied in the same or similar way to Figures 1d to 3b Electronic devices 102, 201, 202, 301 and 302.

[0106] Although not shown, according to one embodiment, the sound-insulating member 759 may be positioned around the foreign object prevention member 657. For example, when viewed from the Z-axis, the sound-insulating member 759 may not overlap with the foreign object prevention member 657, and the foreign object prevention member 657 may be located within the sound-insulating member 759. As another example, the foreign object prevention member 657 may have substantially the same dimensions as the first microphone hole 111, and the internal space of the sound-insulating member 759 may be larger than the internal space of the foreign object prevention member 657.

[0108] Reference Figure 7cRegarding the Z-axis, an electronic device according to another embodiment may include a sound-insulating member 759 and a foreign object prevention member 657 between a second first printed circuit board 152-1 and a housing 110. For example, the sound-insulating member 759 and the foreign object prevention member 657 may be stacked on a second surface (e.g., in the +Z direction) of the second first printed circuit board 152-1, where a first first touch electrode 152b-1 is located. The foreign object prevention member 657 may be located on an inner surface of the housing 110 at a predetermined angle relative to the Z-axis. The sound-insulating member 759 may form a space configured to connect a first first microphone hole 111 and a second first microphone hole 152a-1. One side surface of the sound-insulating member 759 (e.g., Figure 7c The height of the left side surface can differ from that of its other side surface (e.g., Figure 7c The height of the right side surface corresponds to the shell 110 tilted at a predetermined angle.

[0109] Figure 8 This is a view illustrating an electronic device including a plurality of touch electrodes according to an embodiment.

[0110] Reference Figure 8 The electronic device according to one embodiment can be similar to Figures 1a to 7b One of the electronic devices. Figure 8 The electronic device may further include an additional touch electrode 852e (hereinafter referred to as the second touch electrode).

[0111] According to one embodiment, such as Figure 8 As shown, the second touch electrode 852e can be configured to be surrounded by a conductive pattern 120 that can operate as an antenna pattern. The second touch electrode 852e can be located in an empty region of the substrate member 121 on which the conductive pattern 120 is disposed, and can be configured to be substantially surrounded by the conductive pattern 120. Figure 8 Although the second touch electrode 852e is shown as circular, the shape of the second touch electrode 852e is not limited and can be positioned into various shapes based on the shape of the conductive pattern 120.

[0112] According to one embodiment, the first touch electrode 852b (e.g., the first touch electrode 152b-1) and the second touch electrode 852e may be arranged adjacent to each other. For example, when a user performs a first input (e.g., touch) in the housing 110, the first touch electrode 852b and the second touch electrode 852e may be positioned adjacent to each other to detect the user's input substantially simultaneously.

[0113] According to another embodiment, the first touch electrode 852b and the second touch electrode 852e can be positioned spaced apart from each other. For example, when a user performs a second input (e.g., swipe) on the housing 110, the first touch electrode 852b and the second touch electrode 852e can be positioned spaced apart from each other to enable sequential detection of the user's input.

[0114] According to one embodiment, the conductive pattern 120 may be positioned around at least a portion of the first touch electrode 852b. For example, the conductive pattern 120 may be positioned around at least a portion of at least one of a first surface, a second surface, a third surface, or a fourth surface of the quadrilateral first touch electrode 852b.

[0115] The above description Figure 8 The electronic device may include multiple touch electrodes (e.g., a first touch electrode 852b, a second touch electrode 852e, and / or a conductive pattern 120), thus increasing the touch area. Although not shown, according to one embodiment, at least a portion of the multiple touch electrodes (e.g., a first touch electrode 852b, a second touch electrode 852e, and / or a conductive pattern 120) may be electrically connected to each other.

[0116] Figure 9 This is a flowchart illustrating a method for detecting touch input in an electronic device according to an embodiment.

[0117] Reference Figure 9 In operation 901, the processor (or touch sensor module 190) of an electronic device according to an embodiment (e.g., electronic devices 101, 102, 201, 202, 301, and 302) can identify whether a touch is detected at a first touch electrode (e.g., first touch electrodes 152b-1 and 452b-1, first second touch electrodes 152b-2 and 452b-2, first extended touch electrode 452c, and / or second extended touch electrode 452d). For example, the processor (or touch sensor module 190) can identify whether a touch is detected at a predetermined interval at the first touch electrode (e.g., first touch electrodes 152b-1 and 452b-1, first second touch electrodes 152b-2 and 452b-2, first extended touch electrode 452c, and / or second extended touch electrode 452d). If a touch is detected at the first touch electrode as a recognition result in operation 901, the processor can proceed to operation 905, which will be described later. On the other hand, if no touch is detected at the first touch electrode as a recognition result in operation 901, in operation 903, the processor can recognize whether a touch is detected at the second touch electrode (e.g., conductive pattern 120 or second touch electrode 852e).

[0118] If the second touch electrode detects a touch as a recognition result in operation 903, the processor can proceed to operation 905, which will be described later. On the other hand, if the second touch electrode does not detect a touch as a recognition result in operation 903, the processor can return to operation 901.

[0119] In operation 905, the processor according to one embodiment can recognize a touch. For example, the processor can recognize the type of touch detected (e.g., tap, double tap, or long touch).

[0120] In operation 907, the processor according to one embodiment can perform corresponding functions. For example, when music is playing, the processor can send the detected touch type to a connected external electronic device to perform functions such as pausing, stopping, or playing the next song.

[0121] The electronic device may include multiple touch electrodes and detect user touch input via at least one touch electrode. The processor (or touch sensor module 190) of the electronic device may be connected to multiple touch electrodes (e.g., at least one first touch electrode (e.g., first first touch electrodes 152b-1 and 452b-1, first second touch electrodes 152b-2 and 452b-2, first extended touch electrode 452c and / or second extended touch electrode 452d), at least one second touch electrode (e.g., second touch electrode 852e), and / or conductive pattern (e.g., conductive pattern 120) via different touch detection terminals (or connecting members).

[0122] According to one embodiment, at least a portion of a plurality of touch electrodes may be connected to the same touch detection terminal. For example, the plurality of touch electrodes may be connected to a single touch detection terminal. As another example, in the case where the electronic device includes five touch electrodes, the first and second touch electrodes may be connected to the first touch detection terminal, and the third to fifth touch electrodes may be connected to the second to fourth touch electrodes, respectively. When multiple touch electrodes are connected to a single detection terminal, the processor can only identify that a touch has occurred at one of the plurality of touch electrodes, but cannot identify which of the plurality of touch electrodes the touch occurred at.

[0123] Figure 10 This is a flowchart illustrating a method for detecting touch input of an electronic device according to another embodiment.

[0124] Reference Figure 10In operation 1001, the processor (or touch sensor module 190) of an electronic device according to an embodiment (e.g., electronic devices 101, 102, 201, 202, 301, and 302) can identify whether a touch is detected by one of a plurality of touch electrodes (e.g., first touch electrodes 152b-1 and 452b-1, first second touch electrodes 152b-2 and 452b-2, first extended touch electrode 452c, and / or second extended touch electrode 452d) (hereinafter, the first touch electrode).

[0125] If the first touch electrode does not detect a touch as a recognition result in operation 1001, the processor can maintain operation 1001. On the other hand, if the first touch electrode detects a touch as a recognition result in operation 1001, the processor can identify in touch operation 1003 whether the touch was detected by another touch electrode (hereinafter, the second touch electrode) (e.g., the second touch electrode 852e) among the plurality of touch electrodes within a predetermined first time period (e.g., 0.1 seconds).

[0126] If the second touch electrode detects a touch within a predetermined first time period as the recognition result in operation 1003 (e.g., when the first touch electrode and the second touch electrode detect a touch substantially simultaneously), in operation 1005, the processor can execute a first function (e.g., pause or play). On the other hand, if the second touch electrode does not detect a touch within the predetermined first time period as the recognition result in operation 1003, in operation 1007, the processor can identify whether the second touch electrode detected a touch within a predetermined second time period (e.g., 0.5 seconds).

[0127] If the second touch electrode detects a touch as a recognition result in operation 1007 within a predetermined second time period, the processor can perform a second function (e.g., play the next song or the previous song) in operation 1009. For example, if a touch is detected via a second touch detection terminal connected to the second touch electrode after a touch is detected via a first touch detection terminal connected to the first touch electrode, the processor can perform the function of playing the next song; if a touch is detected via a first touch detection terminal connected to the first touch electrode after a touch is detected via a second touch detection terminal connected to the second touch electrode, the processor can perform the function of playing the previous song.

[0128] As a result of the identification in operation 1007, if the second touch electrode does not detect a touch within a predetermined second time period, the process can perform a third function (e.g., ignoring touch input) in operation 1011. According to one embodiment, as a result of the identification in operation 1007, if the second touch electrode does not detect a touch within a predetermined second time period, the processor can perform a first function.
