     BACKGROUND 
     Field 
     The disclosure relates to an electronic device including a touch electrode. 
     Description of Related Art 
     Electronic devices (e.g., a mobile terminal, a smartphone, or a wearable device) may provide various functions. For example, in addition to a basic voice communication function, a smartphone may provide various functions such as a short-range wireless communication (e.g., a Bluetooth™, a Wi-Fi, or a near field communication) function, a mobile communication (third generation (3G), 4G, or 5G) function, a music or video playback function, a photographing function, or a navigation function. 
     Interest in various accessory devices operating in conjunction with the electronic devices is increasing. For example, recently, interest in an in-ear type wireless ear set is increasing. 
     In an in-ear type wireless ear set, various components (e.g., an antenna, a touch electrode, and/or a microphone) may be arranged on a portion exposed to the outside when worn on a user&#39;s ear. However, due to a small size of the wireless ear set, there may be difficulty in arranging a plurality of components on the portion exposed to the outside. For example, the size of the touch electrode may be reduced, and thus touch performance may be deteriorated. 
     SUMMARY 
     Embodiments of the disclosure may provide an electronic device including a touch electrode capable of improving touch sensitivity by expanding a touch area. 
     An electronic device according to various example embodiments, may include: a housing including a first microphone hole; a first printed circuit board positioned in the housing; a touch sensor module comprising a touch sensor positioned on the first printed circuit board; at least one microphone configured to capture external sound; at least one second printed circuit board electrically connected to the first printed circuit board, having the microphone positioned on a first surface oriented toward the interior of the housing, including a second microphone hole and a first touch electrode positioned on a second surface opposite to the first surface to surround the second microphone hole and electrically connected to the touch sensor module, and disposed between the housing and the first printed circuit board to allow the second microphone hole to correspond to the first microphone hole; and a conductive pattern positioned to surround at least a portion of the first touch electrode and electrically connected to the touch sensor module. 
     An electronic device according to various example embodiments, may include: a housing including a first microphone hole; a first printed circuit board positioned in the housing; a touch sensor module comprising a touch sensor positioned on the first printed circuit board; at least one microphone configured to capture external sound; at least one second printed circuit board electrically connected to the first printed circuit board, having the microphone positioned on a first surface oriented toward the interior of the housing, including a second microphone hole and a touch electrode positioned on a second surface opposite to the first surface to surround the second microphone hole and electrically connected to the touch sensor module, and disposed between the housing and the first printed circuit board to allow the second microphone hole to correspond to the first microphone hole; a connection member positioned on the first printed circuit board; and a conductive pattern electrically connected to the touch sensor module positioned on the first printed circuit board via the connection member. 
     An electronic device according to various example embodiments, may include: a housing including a first microphone hole; a first printed circuit board positioned in the housing; a touch sensor module comprising a touch sensor positioned on the first printed circuit board; a wireless communication module comprising communication circuitry positioned on the first printed circuit board and configured to transmit and/or receive a wireless signal; at least one microphone configured to capture external sound; at least one second printed circuit board electrically connected to the first printed circuit board, having the microphone positioned on a first surface oriented toward the interior of the housing, including a second microphone hole and a touch electrode positioned on a second surface opposite to the first surface to surround the second microphone hole and electrically connected to the touch sensor module, and disposed between the housing and the first printed circuit board to allow the second microphone hole to correspond to the first microphone hole; and a conductive pattern positioned in the housing and electrically connected to the touch sensor module and the wireless communication module. 
     Various example embodiments may include a touch electrode in a partial area of a component (e.g., a rigid flexible printed circuit board (RFPCB)) in which a microphone is disposed, and thus may not need a separate component (e.g., an FPCB or a base member (or a carrier)) for a touch electrode, thereby securing a mount place. This may reduce constraints on the design/arrangement of an antenna or a touch pattern. In addition, various example embodiments may expand a touch area and improve touch sensitivity due to the expansion of the touch area. 
     Effects obtainable in the disclosure may not be limited to the above-mentioned effects, and other effects not mentioned may be clearly understood by a person skilled in the art to which the disclosure belongs from the descriptions below.

     According to an embodiment, the first touch electrode  852   b  (e.g., the first-first touch electrode  152   b - 1 ) and the second touch electrode  852   e  may be arranged adjacent to each other. For example, in a case where a user performs a first input (e.g., a touch) in the housing  110 , the first touch electrode  852   b  and the second touch electrode  852   e  may be positioned to be adjacent to each other to detect a user&#39;s input substantially simultaneously. 
     According to an embodiment, the first touch electrode  852   b  and the second touch electrode  852   e  may be positioned to be spaced apart from each other. For example, in a case where a user performs a second input (e.g., swipe) to the housing  110 , the first touch electrode  852   b  and the second touch electrode  852   e  may be positioned to be spaced apart from each other to be capable of sequentially detecting a user&#39;s input. 
     According to an embodiment, the conductive pattern  120  may be positioned to surround at least a portion of the first touch electrode  852   b.  For example, the conductive pattern  120  may be positioned to surround at least a partial area of at least one surface among a first surface, a second surface, a third surface, or a fourth surface of the quadrangular first touch electrode  852   b.

Although not illustrated, according to an embodiment, at least a portion of the multiple touch electrodes (e.g., the first touch electrode  852   b,  the second touch electrode  852   e,  and/or the conductive pattern  120 ) may be electrically connected to each other. 
       FIG.  9    is a flowchart illustrating an example method for detecting touch input of an electronic device according to various embodiments. 
     Referring to  FIG.  9   , in operation  901 , a processor (or a touch sensor module  190 ) of the electronic device (e.g., an electronic device  101 ,  102 ,  201 ,  202 ,  301 , and  302 ) according to an embodiment may identify whether a touch is detected at a first touch electrode (e.g., the first-first touch electrode  152   b - 1  and  452   b - 1 , first-second touch electrode  152   b - 2  and  452   b - 2 , the first extension touch electrode  452   c,  and/or the second extension touch electrode  452   d ). For example, the processor (or a touch sensor module  190 ) may identify whether a touch is detected at the first touch electrode (e.g., the first-first touch electrode  152   b - 1  and  452   b - 1 , first-second touch electrode  152   b - 2  and  452   b - 2 , the first extension touch electrode  452   c,  and/or the second extension touch electrode  452   d ) at predetermined intervals. In a case where a touch is detected by the first touch electrode as a result of identification in operation  901 , the processor may proceed to operation  905  which will be described in greater detail below. On the other hand, in a case where a touch is not detected by the first touch electrode as a result of identification in operation  901 , in operation  903 , the processor may identify whether a touch is detected at a second touch electrode (e.g., the conductive pattern  120  or the second touch electrode  852   e ). 
     In a case where a touch is detected by the second touch electrode as a result of identification in operation  903 , the processor may proceed to operation  905  which will be described in greater detail below. On the other hand, in a case where a touch is not detected by the second touch electrode as a result of identification in operation  903 , the processor may return to operation  901 . 
     The processor according to an embodiment, in operation  905 , may recognize a touch. For example, the processor may recognize the kinds (e.g., a tap, a double tap, or a long touch) of detected touch. 
     In operation  907 , the processor according to an embodiment may perform a corresponding function. For example, in a case where music is being played, the processor may transmit, according to a recognized touch type, the touch type to a connected external electronic device to perform a function such as pause, stop, or play the next song. 
     The electronic device may include multiple touch electrodes and detect a user&#39;s touch input via at least one touch electrode. The processor (or a touch sensor module  190 ) of the electronic device may be connected to the multiple touch electrodes (e.g., at least one first touch electrode (e.g., the first-first touch electrode  152   b - 1  and  452   b - 1 , the first-second touch electrode  152   b - 2  and  452   b - 2 , the first extension touch electrode  452   c,  and/or the second extension touch electrode  452   d ), at least one second touch electrode (e.g., the second touch electrode  852   e ), and/or a conductive pattern (e.g., the conductive pattern  120 ) via different touch detection terminals (or connection members), respectively. 
     According to an embodiment, at least a portion of the multiple touch electrodes may be connected to the same touch detection terminal. For example, multiple touch electrodes may be connected to one touch detection terminal. For another example, in a case where the electronic device includes five touch electrodes, a first touch electrode and a second touch electrode may be connected to a first touch detection terminal, and a third touch electrode to a fifth touch electrode may be connected to a second to a fourth touch electrode, respectively. In a case where multiple touch electrodes are connected to one detection terminal, the processor may only recognize that a touch has occurred at one of the multiple touch electrodes and may not recognize at which of the multiple touch electrodes the touch has occurred. 
       FIG.  10    is a flowchart illustrating an example method for detecting touch input of an electronic device according to an embodiment. 
     Referring to  FIG.  10   , in operation  1001 , a processor (or a touch sensor module  190 ) of an electronic device (e.g., an electronic device  101 ,  102 ,  201 ,  202 ,  301 , and  302 ) according to an embodiment may identify whether a touch is detected by one of multiple touch electrodes (hereinafter, a first touch electrode) (e.g., the first-first touch electrode  152   b - 1  and  452   b - 1 , the first-second touch electrode  152   b - 2  and  452   b - 2 , the first extension touch electrode  452   c,  and/or the second extension touch electrode  452   d ). 
     In a case where a touch is not detected by the first touch electrode as a result of identification in operation  1001 , the processor may maintain operation  1001 . On the other hand, in a case where a touch is detected by the first touch electrode as a result of identification in operation  1001 , the processor may identify whether a touch is detected by another touch electrode (hereinafter, a second touch electrode) (e.g., the second touch electrode  852   e ) of the multiple touch electrodes in a predetermined first time period (e.g., 0.1 seconds) in operation  1003 . 
     As a result of identification in operation  1003 , in a case where a touch is detected by the second touch electrode in a predetermined first time period (e.g., in a case where a touch is detected by the first touch electrode and the second touch electrode substantially simultaneously), the processor may perform a first function (e.g., pause or play) in operation  1005 . On the other hand, as a result of identification in operation  1003 , in a case where a touch is not detected by the second touch electrode in a predetermined first time period, the processor may identify whether a touch is detected by the second touch electrode in a predetermined second time period (e.g., 0.5 seconds) in operation  1007 . 
     As a result of identification in operation  1007 , in a case where a touch is detected by the second touch electrode in a predetermined second time period, the processor may perform a second function (e.g., play the next song or the previous song) in operation  1009 . For example, in a case where a touch is detected via a second touch detection terminal connected to the second touch electrode after the touch is detected through the first touch detection terminal connected to the first touch electrode, the processor may perform playing the next song, and in a case where a touch is detected through the first touch detection terminal connected to the first touch electrode after the touch is detected via the second touch detection terminal connected to the second touch electrode, the processor may perform playing the previous song. 
     As a result of identification in operation  1007 , in a case where a touch is not detected by the second touch electrode in a predetermined second time period, the process may perform a third function (e.g., ignoring touch input) in operation  1011 . According to an embodiment, as a result of identification in operation  1007 , in a case where a touch is not detected by the second touch electrode in a predetermined second time period, the processor may perform the first function.
