       [0030]    Specific embodiments in this disclosure have been shown by way of example in the foregoing drawings and are hereinafter described in detail. The drawings and written description are not intended to limit the scope of the inventive concepts in any manner. Rather, they are provided to illustrate the inventive concepts to a person skilled in the art by referring to particular embodiments. 
       DETAILED DESCRIPTION 
       [0031]    The exemplary embodiments of the present disclosure will be described in combination with the drawings, and it should be appreciated that the exemplary embodiments described herein are only used for describing and explaining the present disclosure, but are not for limiting the present disclosure. 
         [0032]    As shown in  FIG. 1 , which is a schematic diagram of a three-stage headset plug, the headset plug includes three terminals, which are respectively a left channel, a right channel and GND (ground). As shown in  FIG. 2 , which is a schematic diagram of a four-stage headset plug, the headset plug has four terminals, which are respectively a left channel, a right channel, a microphone and GND (ground). In general, when the user connects the headset with an electronic device, the user needs to insert the headset plug into a headset jack of the electronic device. The headset jack of electronic device is a headset jack matched with the standard headset plug. Generally, in the electronic device, the layout of the positions of the headset jack and the screen may be as follows. 
         [0033]    1. The headset jack is configured at the top or bottom of the electronic device and keeps away from the screen, as shown in  FIG. 3 , which is a schematic diagram of a state of inserting the headset plug when the headset jack is configured at the top of the electronic device. For example, the headset jack is a headset jack matched with a 3.5 mm headset plug, and the 3.5 mm headset plug has a length of 14 mm. Then, in order to keep the headset jack away from the screen, the area above or below the screen is set to be greater than 14 mm. 
         [0034]    2. The headset jack is configured at a lateral side of the electronic device (e.g., a mobile phone) and keeps away from the screen, as shown in  FIG. 4 . Such solution needs to increase the thickness of the electronic device such that the headset jack and the screen could be staggered in the thickness direction. 
         [0035]    However, in the above-mentioned first solution, the area above or below the screen is too large, while in the second solution, the thickness of the electronic device will be increased. Therefore, it is difficult to provide increasingly thinner electronic device and increasingly larger screen to users. 
         [0036]    Accordingly, the present disclosure provides a connection member for the headset plug, wherein the connection member includes at least one pin. When the connection member is connected with the headset plug, the at least one pin of the connection member is communicated with at least one terminal of the headset plug near an end portion thereof. 
         [0037]    In one embodiment, the connection member may be of any shape, and the form of connection with the headset plug may also be of any type, as long as the connection member includes at least one pin which can communicate with at least one terminal of the headset plug positioned near an end portion of the headset plug when the connection member is connected with the headset plug. 
         [0038]    As shown in  FIG. 5  which illustrates one embodiment of the connection member, in this embodiment, the connection member is a sleeve  501 . The sleeve is hollow, as indicated by the reference sign  502  in  FIG. 5 . The inner diameter r of the sleeve matches the size of the end portion of the headset plug, i.e., the sleeve can accommodate the end portion of the headset plug. Moreover, the height h of the sleeve is greater than or equal to the sum of widths of the terminals of the headset plug to be communicated. The sleeve has a pin  503 , such as a clip. When the connection member is in use, the sleeve  501  is put on a tail portion of the three-stage headset plug, as shown in  FIG. 6 , and at this time, the pin  503  of the sleeve is communicated with one terminal of the headset plug  601  near the tail portion. As shown in  FIG. 7 , the headset plug  601  is inserted into the headset jack  602 , and the pin  503  is communicated with a corresponding contact point in the headset jack  602  (the contact point in the headset jack is not shown in the drawing). In this embodiment, the headset plug is not fully inserted into the headset jack, and the terminal of the headset plug which is not inserted into the headset jack is communicated with the contact point in the headset jack via the pin of the connection member. As compared with  FIG. 3 , the portion of the headset plug which is inserted into the headset jack is short, therefore, the required depth m of the headset jack becomes relatively small. As compared with  FIG. 3 , the depth m is inevitably less than 14 mm, therefore, the screen of the electronic device configured with this kind of headset jack can be set relatively large. 
         [0039]    As shown in  FIG. 8  which illustrates another embodiment of the connection member, in this embodiment, the connection member is also a sleeve  801 . The sleeve is hollow, as indicated by the reference sign  802  in  FIG. 8 . The inner diameter r of the sleeve can accommodate the end portion of the headset plug; and the height h of the sleeve is greater than or equal to the sum of the widths of terminals of the headset plug to be communicated. The sleeve includes two pins  803  and  804 . When the connection member is in use, the sleeve  801  is put on the tail portion of the headset plug  901 , and as shown in  FIG. 9 , the four-stage headset plug  901  is taken as an example. At this time, the pins  803  and  804  of the sleeve are respectively communicated with two terminals  805  and  806  of the headset plug  901  near the tail portion. As shown in  FIG. 10 , the headset plug  901  is inserted into the headset jack  902 , and the pins  803  and  804  of the sleeve  801  are respectively communicated with corresponding contact points in the headset jack  902  (the contact points in the headset jack are not shown in the drawing). In this embodiment, the headset plug is not fully inserted into the headset jack, and the terminals of the headset plug  901  which are not inserted into the headset jack  902  are communicated with the contact points in the headset jack  902  via the pins of the connection member  801 . Therefore, as compared with the condition that the headset plug is fully inserted into the headset jack, the required depth m of the headset jack becomes relatively small. Therefore, the screen of the electronic device configured with this headset jack can be set relatively large. 
         [0040]    In other embodiments of the present disclosure, when the headset jack is configured on the front of the electronic device or on the back of the electronic device, the connection member proposed in the present disclosure may also be applied when the headset with a standard headset plug is in use. 
         [0041]    Furthermore, when using the connection member, it may also be possible to communicate the pin of the connection member with at least one terminal of the headset plug positioned near a head portion of the headset plug. As shown in  FIG. 11 , the headset plug  1101  is firstly inserted into the headset jack  1102 , and then the sleeve  1103  is put on the head portion of the headset plug  1101 . At this time, the pins  1104  and  1105  of the sleeve are respectively communicated with the two terminals  1106  and  1107  of the headset plug  1101  near the head portion. Moreover, the pins  1104  and  1105  of the sleeve  1103  are respectively communicated with corresponding contact points in the headset jack  1102  (the contact points in the headset jack are not shown in the drawing). In this embodiment, the headset plug is fully inserted into the headset jack with a shallower depth, and the terminals of the headset plug  1101  protruding out of the headset jack  1102  are communicated with the contact points in the headset jack  1102  via the pins of the connection member  1103 . Therefore, the required depth of the headset jack can become relatively small, and thereby, the electronic device configured with this headset jack may be set relatively thin. 
         [0042]    In other embodiments of the present disclosure, for example, the connection member can also be a clamp with a pin for clamping the terminal of the headset plug so as to be connected to the headset plug and for communicating the pin with the terminal of the clamped headset plug. 
         [0043]    The present disclosure also provides a headset jack cooperating with the aforesaid connection member and having at least one contact point. When the headset plug is inserted into the headset jack, and the headset plug is connected with the connection member, said at least one contact point is communicated with at least one pin of the connection member. The connection member is configured as follows: when the connection member is connected to the headset plug, at least one pin of the connection member is communicated with at least one terminal of the headset plug near an end portion thereof. 
         [0044]    The depth of the headset jack is determined by subtracting a sum of widths of the terminals communicated with the pins of the connection member from a sum of widths of all terminals of the headset plug, when the headset plug is connected to the connection member. 
         [0045]    The at least one contact point may be located at an end portion of the headset jack or within a channel of the headset jack.  FIG. 12  illustrates a schematic diagram of one embodiment of the headset jack.  FIG. 12  is a top view of the headset jack, wherein the reference sign  1201  indicates the headset jack with a hollow center portion  1202  for inserting the headset plug, and the contact points  1203  and  1204  are located at the end portion of the headset jack  1201  for communicating with the pins of the connection member. In other embodiments of the present disclosure, the contact points may be located within the center portion  1202 . 
         [0046]    The present disclosure also provides an electronic device.  FIG. 13  is a structural diagram of an electronic device provided by the present disclosure. Referring to  FIG. 13 , the electronic device  1100  may include a communication unit  110 , a memory  120  including one or more computer-readable storage medium, an input unit  130 , a display unit  140 , a sensor  150 , an audio circuit  160 , a WiFi (wireless fidelity) module  170 , a processor  180  including one or more processing core members, a power supply  190 , and other components. The person skilled in the art should appreciate that the structure of the electronic device shown in  FIG. 13  does not constitute the limitation to the electronic device, but may include more or less components than those shown in the drawing, or may combine some of the components, or may have different arrangement of the components. 
         [0047]    The communication unit  110  is configured to receive and transmit signals during information receipt and transmission or during a call. The communication unit  110  may be a RF (radio frequency) circuit, a router, a modem, or other network communication device. Specifically, in the case that the communication unit  110  is the RF circuit, after receiving the downlink information from the base station, the one or more processors  780  processes the downlink information; additionally, the uplink data is transmitted to the base station. Generally, the RF circuit serving as the communication unit includes, but is not limited to an antenna, at least one amplifier, a tuner, one or more oscillators, a subscriber identity module (SIM) card, a transceiver, a coupler, a LNA (Low Noise Amplifier), a duplexer, etc. Additionally, the communication unit  110  may also communicated with network and other devices via wireless communication.

The memory  120  may mainly include a program storage part and a data storage part, wherein the program storage part may store instructions for an operation system, an application program required by at least one function (such as an audio playing function, an image playback function) and the like; and the data storage part may store the data created according to the usage of the electronic device  1100  (such as audio data, a phone book) and the like. In addition, the memory  120  may include a high random access memory, and may also include a non-transitory memory, such as at least one disc storage device, flash device or other transitory solid-state storage device. Accordingly, the memory  120  may also include a memory controller for providing the processor  180  and the input unit  130  with an access to the memory  120 . 
         [0048]    The input unit  130  may be configured to receive the input digits or character information, and generate signal inputs of a keyboard, a mouse, a joystick or a trackball related to the user settings and function control. For example, the input unit  130  may include a touch sensitive surface  131  and other input devices  132 . The touch sensitive surface  131 , which is also be referred to as a touch screen or a touch pad, can collect the user&#39;s touch operation thereon or thereabout (for example, the user performs operations on the touch sensitive surface  131  or near the touch sensitive surface  131  by using fingers, a stylus, or any suitable object or accessory), and drive the corresponding connected device according to the preset program. Optionally, the touch sensitive surface  131  may include two parts, i.e., a touch detection device and a touch controller, wherein the touch detection device detects a touch orientation of the user and signals caused by the touch operation, and transmits the signals to the touch controller; and the touch controller receives the touch information from the touch detection device, converts the touch information into a contact coordinate and transmits it to the processor  180 , and the touch controller can also receive the instruction from the processor  180  and execute the instruction. Additionally, the touch sensitive surface  131  may be achieved by adopting various types, such as a resistive type, a capacitive type, an infrared ray type, and a surface acoustic wave type. Besides the touch sensitive surface  131 , the input unit  130  may also include other input device  132 . The other input devices  132  may include but not limited to one or more of a physical keyboard, a function key (such as a volume control key, a switch key), a trackball, a mouse, a joystick, etc.

Further, the touch sensitive surface  131  may cover with the display panel  141 . When the touch operation on or near the touch sensitive surface  131  is detected, the touch sensitive surface  131  transmits the touch operation to the processor  180  to determine the type of the touch event, and then the processor  180  provides a corresponding visual output on the display panel  141  according to the type of the touch event. Although in  FIG. 13 , the touch sensitive surface  131  and the display panel  141  act as two independent components to achieve input and input functions, in some embodiments, the touch sensitive surface  131  and the display panel  141  may be integrated to achieve the input and output functions.

The audio circuit  160  may transmit an electrical signal converted from the received audio data to the speaker  161 , and the speaker  161  converts the electrical signal into an acoustical signal and outputs it. On the other hand, the microphone  162  converts the collected acoustical signal into an electrical signal, the audio circuit  160  receives the electrical signal, converts it into an audio signal, and output the audio signal to the processor  180  for being processed, then the processed audio signal is for example transmitted to another electronic device via the RF circuit  110 , or the audio signal is output to the memory  120  for further processing. The audio circuit  160  may also include a headset jack for providing the communication between the peripheral headset and the electronic device  1100 .

         [0052]    The depth of the headset jack is determined by subtracting a sum of widths of the terminals communicated with the pins of the connection member from a sum of widths of all terminals of the headset plug, when the headset plug is connected to the connection member. 
         [0053]    The at least one contact point may be located at the end portion of the headset jack of the electronic device or within the channel of the headset jack of the electronic device.
