Description:
CROSS REFERENCE TO RELATED APPLICATIONS 
       [0001]    This application is a continuation of International Application No. PCT/CN2013/078932, filed Jul. 5, 2013, which is based upon and claims priority of Chinese Patent Application No. 201210383278.2, fled Oct. 10, 2012, the entire contents of which are incorporated herein by reference. 
     
    
     TECHNICAL FIELD 
       [0002]    The present disclosure relates generally to wireless communication and, more particularly, to a device including a mobile terminal and a pendant connected therewith. 
       BACKGROUND 
       [0003]    An antenna is essential for a device to perform wireless communication. A variety of antennae can be used to meet different requirements associated with frequencies, applications, situations and the like. Based on a position relation with the device, antennae can be classified as two kinds, i.e., built-in antenna and external antenna. 
         [0004]    For a mobile phone, a conventional built-in antenna arrangement is typically achieved by making an internal antenna using a flexible printed circuit board (FPCB), which is attached to the inside of a phone shell and connected to antenna contacts on a circuit board of the mobile phone via brackets or pins, allowing the connection between the antenna and an antenna circuit on the circuit board. 
         [0005]    However, in the conventional built-in antenna arrangement, a certain space for antenna contacts is needed to be reserved on the circuit board of the mobile phone, which may cause insufficient remaining space available. As mobile phones have more and more functions, the space shortage problem of the circuit board caused by antenna contacts is considerably rising. Furthermore, the antenna being included inside the phone shell may lead to an increase of a thickness of the mobile phone. 
       SUMMARY 
       [0006]    According to a first aspect of the present disclosure, there is provided a pendant for use with a mobile terminal, comprising: a pendant body containing an antenna; and a pendant cord connected with the pendant body, the pendant cord enclosing a cable connected to the antenna for transmitting and receiving radio frequency signals. 
         [0007]    According to a second aspect of the present disclosure, there is provided a device, comprising: a mobile terminal; and a pendant connected to the mobile terminal, wherein the pendant includes a pendant body containing an antenna, and a pendant cord enclosing a cable connected to the antenna for transmitting and receiving radio frequency signals. 
         [0008]    It is to be understood that both the foregoing general description and the following detailed description are exemplary and explanatory only and are not restrictive of the invention, as claimed.

     DETAILED DESCRIPTION 
       [0015]    Reference will now be made in detail to exemplary embodiments, examples of which are illustrated in the accompanying drawings. The following description refers to the accompanying drawings in which the same numbers in different drawings represent the same or similar elements unless otherwise represented. The implementations set forth in the following description of exemplary embodiments do not represent all implementations consistent with the invention. Instead, they are merely examples of apparatuses and methods consistent with aspects related to the invention as recited in the appended claims. 
         [0016]      FIG. 1  is a schematic diagram of a pendant  10  for use with a mobile terminal, according to an exemplary embodiment. Referring to  FIG. 1 , the pendant  10  includes a pendant body  11  and a pendant cord  12  connected to the pendant body  11 . 
         [0017]    In exemplary embodiments, the pendant body  11  is structured to contain an antenna  20 , such that the antenna  20  is built into the pendant body  11 . The pendant cord  12  is implemented with a hollow cord to enclose one or more cables  21  connected to the antenna  20  for transmitting and receiving radio frequency (RF) signals. In addition, one or more connecting contacts  22  are located at an end of the cables  21  for contact with antenna contacts in the mobile terminal (not shown), such that the antenna  20  built in the pendant body  11  is connected with the mobile terminal. 
         [0018]    With reference to  FIG. 2 , in exemplary embodiments, the pendant  10  further includes a first connecting component  13 . As shown in  FIG. 2 , the connecting contacts  22  are disposed in the first connecting component  13 . Further, the antenna contacts are disposed in a second connecting component (not shown) of the mobile terminal, which can be detachably or non-detachably connected to the first connecting component  13 . 
         [0019]    In one exemplary embodiment, the second connecting component of the mobile terminal is non-detachably connected to the first connecting component  13  of the pendant  10 . For example, the connecting contacts  22  in the first connecting component  13  are connected to the antenna contacts in the second connecting component through soldering. Specifically, the first connecting component  13  can be integral with the second connecting component, and the connecting contacts  22  in the first connecting component  13  can be welded to the antenna contacts in the second connecting component. 
         [0020]    In one exemplary embodiment, the second connecting component of e mobile terminal is detachably connected with the first connecting component  13  of the pendant  10 . Accordingly, the connecting contacts  22  in the first connecting component  13  will be in contact with the antenna contacts in the second connecting component when the first connecting component  13  is in connection with the second connecting component. 
         [0021]    In exemplary embodiments, the detachable connection between the first connecting component  13  of the pendant  10  and the second connecting component of the mobile terminal may be a snap-fit connection, a threaded connection, or a plug-in connection. For example,  FIG. 3  is a schematic diagram showing an exemplary snap-fit connection between the first connecting component  13  of the pendant  10  and the second connecting component, represented by a connecting component  31 , of the mobile terminal. 
         [0022]    The detachable connection is not specifically limited in the present disclosure, and any means other than the above mentioned detachable connection can be employed. 
         [0023]    Referring back to  FIG. 2 , in exemplary embodiments, the detachable connection can also be achieved by using various data input/output (I/O) interfaces of the mobile terminal, such as an audio I/O interface, a universal serial bus (USB) interface, a firewire (IEEE 1394) interface, or a power interface, as components for connecting the pendant  10  to the mobile terminal. For example, when a data I/O interface of the mobile terminal is used as the second connecting component, and a port corresponding to the data I/O interface is used as the first connecting component  13 . The connecting contacts  22  in the first connecting component  13  will be in contact with the antenna contacts in the second connecting component when the first connecting component  13  is in connection with the second connecting component. 
         [0024]    In exemplary embodiments, when a data I/O interface of the mobile terminal is used as the second connecting component, the data I/O interface can be dedicatedly used to connect the first connecting component  13 , for realizing the connection between the antenna  20  built in the pendant body  11  and the mobile terminal. For example, a USB interface of the mobile terminal, which is dedicatedly used to connect the pendant  10 , can serve as the second connecting component, and the first connecting component  13  of the pendant  10  can be a port corresponding to the USB interface. 
         [0025]    Alternatively, the data I/O interface is used not only to connect the pendant  10 , but also to connect another external unit. For example, the pendant  10  can share the data I/O interface of the mobile terminal with the external unit, and the connection with the data I/O interface can be switched between the pendant  10  and the external unit by using a controller in, e.g., the mobile terminal. For example, the audio I/O interface of the mobile terminal can serve as the second connecting component, and the first connecting component  13  of the pendant  10  can be a port corresponding to the audio I/O interface. The audio I/O interface can be connected to the first connecting component  13  of the pendant  10  as well as a port of an earphone with the connection switched by the controller. 
         [0026]    In exemplary embodiments, the antenna  20  is a low frequency antenna. Since the antenna  20  built in the pendant  11  is arranged outside the mobile terminal, the antenna  22  being a low frequency antenna can improve communication quality. 
         [0027]    In one exemplary embodiment, the antenna  22  is a near field communication (NFC) antenna, for the mobile terminal to perform wireless communications with another device, such as a contactless smart card, within a certain range. NFC is a short-range low frequency wireless communication technology, allowing a contactless point-to-point data transmission between electronic devices. NFC features high bandwidth, low energy consumption and the like due to its unique signal attenuation model. In addition, NFC is compatible with contactless smart cards and is becoming a formal standard. Furthermore, NFC can allow various devices to securely, rapidly, and automatically communicate with each other by applying a near field connection protocol. Compared to other wireless communication technologies, NFC can be used in private communications within a short range. NFC plays an important role in the field of access control management, bus card identification, mobile payment and the like. 
         [0028]    In one exemplary embodiment, the antenna  20  is arranged in the pendant body  11  in a manner of homocentric squares. 
         [0029]    In the above illustrated embodiments, the antenna  20  is built in the pendant body  11  of the pendant  10 , such that when the pendant  10  is connected to the second connecting component of the terminal through the first connecting component  13 , the connecting contacts in the first connecting component  13  are in contact with the antenna contacts in the second connecting component, which implements the connection between the antenna  20  built in the pendant body  11  and the mobile terminal. Thus, due to the built-in arrangement in the pendant  10  that is separated from the mobile terminal, the antenna  20  is disposed outside the mobile terminal, which helps saving space in the mobile terminal. 
         [0030]      FIG. 4  illustrates a block diagram of a device  40 , according to an exemplary embodiment. Referring to  FIG. 4 , the device  40  includes a mobile terminal  41  and the pendant  10  as described above in connection with  FIGS. 1 and 2 . 
         [0031]    In exemplary embodiments, the mobile terminal  41  includes a processor  42  configured to execute program instructions to perform wireless communications, and one or more data I/O interfaces  44 , such as an audio I/O interface, a universal serial bus (USB) interface, a firewire (IEEE 1394) interface, or a power interface. The mobile terminal  41  is connected with the pendant body  11  through the pendant cord  12 . 
         [0032]      FIG. 5  is a schematic diagram showing a connection between the mobile terminal  41  and the pendant  10  ( FIG. 4 ), according to an exemplary embodiment. For illustrative purposes, only a corner of the mobile terminal  41  is shown in  FIG. 5 . Referring to  FIG. 5 , antenna contacts  32  in the second connecting component (not shown) of the mobile terminal  41  will be in contact with the connecting contacts  22  in the first connecting component  13  of the pendant  10 , when the first and second connecting components are connected with each other. 
         [0033]    In exemplary embodiments, to facilitate wiring in the mobile terminal  41  and the connection with the first connecting component  13  in the pendant  10 , the second connecting component is disposed in any one of, e.g., four, corners of the mobile terminal  41 , and the antenna contacts  32  in the second connecting component are disposed in a corner of a circuit board corresponding to the position of the second connecting component. In the illustrated embodiment, the second connecting component is disposed in the lower right corner of the mobile terminal  41  and, accordingly, the antenna contacts  32  in the second connecting component are disposed in the lower right corner of the circuit board, as viewed in  FIG. 5 . 
         [0034]    In the above illustrated embodiments, the antenna  20  is built in the pendant body  11  of the pendant  10 , such that when the pendant  10  is connected to the second connecting component of the terminal  41  through the first connecting component  13 , the connecting contacts  22  in the first connecting component  13  are in contact with the antenna contacts  32  in the second connecting component, which implements the connection between the antenna  20  built in the pendant body  11  and the mobile terminal  41 . Thus, due to the built-in arrangement in the pendant  10  that is separated from the mobile terminal  41 , the antenna  20  is disposed outside the mobile terminal  41 , which saves space in the mobile terminal  41 .
