CROSS-REFERENCE TO RELATED APPLICATION AND PRIORITY CLAIM 
       [0001]    This application claims priority from Chinese patent application No. 201310451532.2, filed Sep. 25, 2013, the entire disclosure of which hereby is incorporated by reference. 
       TECHNICAL FIELD 
       [0002]    The present disclosure relates to a microphone, and particularly, to a packaging component and a packaging method for a microphone and an electronic device having the packaging component. 
       BACKGROUND 
       [0003]    Currently, electronic devices, especially mobile terminals are developed rapidly, and assemblies thereof are becoming smaller in size and water-proof. With the wide application of a microphone in various electronic devices, how to reliably package a microphone becomes a challenge. 
         [0004]    In a sealing structure of an existing microphone, a microphone holder (MIC holder) and a housing are usually bonded together by a conventional adhesive or a hook. Since an adhesive or a hook cannot push parts needing to be bonded in the sealing structure of the existing microphone, enough force cannot be applied to seal the microphone. Moreover, since an adhesive or a hook can easily age, a reliable sealing effect cannot be achieved.

       Embodiment 1 
       [0036]    The embodiment of the present invention provides a packaging component for a microphone.  FIG. 1  is a schematic diagram of a packaging component for a microphone according to the embodiment of the present invention;  FIG. 2  is a cross-sectional diagram of the packaging component for the microphone according to the embodiment of the present invention; and they illustrate some constitution or structure of the packaging component for the microphone. 
         [0037]    As illustrated in  FIGS. 1 and 2 , the packaging component for the microphone  101  includes: 
         [0038]    a microphone holder  102  configured to fix the microphone  101 ; 
         [0039]    a housing  103  configured to package the microphone holder  102 ; 
         [0040]    a fixing member  104  configured to fixedly connect the microphone holder  102  to the housing  103 , wherein the fixing member  104  has a via hole  105  passing therethrough, and the via hole  105  is communicated with a space  106  of the microphone holder  102  to form an acoustic channel of the microphone  101 . 
         [0041]    Thus, through the fixing member  104  according to the embodiment of the present invention, the microphone holder  102  may be fixed on the housing  103  to reliably connect the microphone holder and the housing, which is beneficial to the waterproof sealing of an electronic device. Moreover, the acoustic channel of the microphone  101  is formed by the via hole  105  throughout the fixing member, without requiring an additional space to form the acoustic channel. Thus, the microphone holder can be fixed by a minimum space, which is beneficial to the miniaturization of the electronic device. 
         [0042]    In an implementation, the fixing member  104  may be a self-tapping screw which has a via hole throughout the entire self-tapping screw along an axis. In this case, the self-tapping screw of the present invention may be formed by boring a hole in a common self-tapping screw, or obtained by forming a thread on the surface of a tube. 
         [0043]    For example, a thread may be formed on the surface of a first tube with a proper size, the first tube having the thread being taken as a screw body and a second tube with a proper size being taken as a screw head, and then the first and second tubes may be welded together to form the self-tapping screw in the present invention. But the present invention is not limited thereto, and a specific manufacturing manner can be determined according to an actual condition. 
         [0044]      FIG. 3  is a schematic diagram of a fixing member  104  according to the embodiment of the present invention, and  FIG. 4  is a cross-sectional diagram of the fixing member  104  according to the embodiment of the present invention. As illustrated in  FIGS. 3 and 4 , the fixing member  104  may be a self-tapping screw, which includes a screw body  307  and a screw head  308 . As illustrated in  FIG. 3  or  4 , the self-tapping screw further includes a via hole  305  throughout an axis thereof. 
         [0045]    Thus, by fixing the microphone holder and the housing to each other through the self-tapping screw having a via hole, it is possible to package the microphone just using a simple structure, thereby saving the space while keeping the reliability. 
         [0046]    As illustrated in  FIG. 3  or  4 , the screw head  308  of the self-tapping screw  104  may have a cross pattern or a line pattern, which is beneficial to perform the fixing by using the self-tapping screw, and a relatively large force can be produced to tighten the self-tapping screw. But the present invention is not limited thereto, and a screw having a via hole and other patterns shall also fall within the scope of the present invention. 
         [0047]    In this embodiment, the microphone  101  may first be fixed on the microphone holder  102 , then the microphone holder  102  and the housing  103  are fixed to each other by using the self-tapping screw  104  having the via hole  305 . Once the self-tapping screw  104  is pushed, the self-tapping screw applies a force to compact cushions  401  between the microphone holder  102  and the housing  103 , and thus the microphone holder  102  and the housing  103  are securely bonded with each other. Furthermore, since the self-tapping screw has the via hole  305  throughout the axis thereof and the via hole  305  is communicated with the space  106  of the microphone holder  102  to form an acoustic channel of the microphone  101 , the sound wave can enter the microphone  101 . 
         [0048]    In another implementation, the fixing member  104  may be in threaded connection with the microphone holder  102  and the housing  103 . During the particular implementation, a first via hole may be formed on the microphone holder  102  and the housing  103 , with a first thread (not illustrated) formed on the inner wall of the first via hole; moreover, a second thread fitted with the first thread on the inner wall of the first via hole may be formed on the outer wall of the fixing member having a second via hole  105 . 
         [0049]    Specifically, after the microphone  101  is fixed on the microphone holder  102 , the microphone holder  102  and the housing  103  are fixed by using the fixing member  104  having the via hole  105 . Once the fixing member  104  is pushed, the fixing member  104  applies a force to compact cushions  401  between the microphone holder  102  and the housing  103 , and thus the microphone holder  102  and the housing  103  are securely bonded with each other. Furthermore, since the fixing member  104  has the via hole  105  throughout the axis thereof and the via hole  105  is communicated with the space  106  of the microphone holder  102  to form an acoustic channel of the microphone  101 , the sound wave can enter the microphone  101 . 
         [0050]    To be noted, the fixing member according to the embodiment of the present invention is just schematically described through the self-tapping screw and the threaded connection. But the present invention is not limited thereto, and the specific structure may be determined according to an actual condition. In addition, the material and size of the fixing member can also be determined according to an actual demand. 
         [0051]    Through the above embodiment, a microphone holder can be fixed by a minimum space by fixedly connecting the microphone holder and a housing using a fixing member having a via hole, which is beneficial to the miniaturization of an electronic device; moreover, the microphone holder and the housing can be reliably connected to each other through the tightening by the fixing member, which is beneficial to the waterproofing of the electronic device. 
       Embodiment 2 
       [0052]    The embodiment of the present invention provides a packaging method for a microphone, which method uses the packaging component for the microphone as described in embodiment 1.  FIG. 5  is a flow chart of a packaging method for a microphone according to the embodiment of the present invention. As illustrated in  FIG. 5 , the packaging method includes: 
         [0053]    Step  501 : forming a via hole in a fixing member; 
         [0054]    Step  502 : fixedly connecting a microphone holder to a housing by using the fixing member having the via hole, such that the via hole is communicated with a space of the microphone holder to form an acoustic channel of the microphone. 
         [0055]    In this embodiment, the fixing member may be a self-tapping screw, in which a via hole throughout a screw body and a screw head may be formed. Please refer to the existing machining method for the specific method of forming the via hole. In addition, a plurality of parts may also be welded or riveted together to form a fixing member having a via hole. The present invention is not limited thereto, and the specific implementation can be determined according to an actual condition. 
         [0056]    In this embodiment, it is not required to form in advance a via hole in the microphone holder and the housing by connecting the microphone holder to the housing through the self-tapping screw having the via hole, and thus the structure is simple and easy to be applied. In addition, a via hole may also be formed in the microphone holder and the housing in advance, and a thread may be formed on the inner wall of the via hole; the microphone holder and the housing are connected to each other by the fixing member having the via hole through the thread, which facilitates the assembly and disassembly, thereby allowing the repeated use and benefiting the replacement. The present invention is not limited thereto, and the specific fixing manner can be determined according to an actual condition. 
         [0057]    The embodiment of the present invention further provides an electronic device having a microphone and further including the packaging component for the microphone as described in Embodiment 1. The electronic device may be a mobile terminal. But the present invention is not limited thereto, and any electronic device having a microphone is suitable for the present invention. 
         [0058]    Through the above embodiment, a microphone holder can be fixed by a minimum space by fixedly connecting the microphone holder and a housing using a fixing member having a via hole, which is beneficial to the miniaturization of an electronic device; moreover, the microphone holder and the housing can be reliably connected to each other through the tightening by the fixing member, which is beneficial to the waterproofing of the electronic device.
