     DETAILED DESCRIPTION 
       [0009]    It will be appreciated that for simplicity and clarity of illustration, where appropriate, reference numerals have been repeated among the different figures to indicate corresponding or analogous elements. In addition, numerous specific details are set forth in order to provide a thorough understanding of the embodiments described herein. However, it will be understood by those of ordinary skill in the art that the embodiments described herein can be practiced without these specific details. In other instances, methods, procedures, and components have not been described in detail so as not to obscure the related relevant feature being described. Also, the description is not to be considered as limiting the scope of the embodiments described herein. The drawings are not necessarily to scale and the proportions of certain parts may be exaggerated to better illustrate details and features of the present disclosure. 
         [0010]    Several definitions that apply throughout this disclosure will now be presented. 
         [0011]    The term “substantially” is defined to be essentially conforming to the particular dimension, shape, or other feature that the term modifies, such that the component need not be exact. For example, “substantially cylindrical” means that the object resembles a cylinder, but can have one or more deviations from a true cylinder. The term “comprising” when utilized, means “including, but not necessarily limited to”; it specifically indicates open-ended inclusion or membership in the so-described combination, group, series and the like. 
         [0012]    The present disclosure is described in relation to a housing of electronic device. 
         [0013]      FIGS. 1-3  illustrate one embodiment of a housing of an electronic device  100 . The housing of electronic device  100  includes a plurality of vibration devices  10  and a shell  20 . 
         [0014]    Each vibration device  10  includes a main portion  12 , a magnet  14 , and an elastic element  16 . The magnet  14  and the elastic element  16  are received in the main portion  12 . In one embodiment, the elastic element  16  can be a coil. 
         [0015]    The shell  20  includes a first plate  22 , a second plate  24 , and a ring seal  26 . The first plate  22  and the second plate  24  are fixed by the ring seal  26 . An enclosed space  28  is defined by the first plate  22 , the second plate  24 , and the ring seal  26 . The enclosed space  28  is filled with gas. A thickness of the second plate  24  is greater than a thickness of the first plate  22 . In an embodiment, the first plate  22  can be substantially parallel to the second plate  24 . The first plate  22  and the second plate  24  can be made of glass. The first plate  22  can be flexible. The ring seal  26  can be made of elastic material. In an embodiment, the thickness of the first plate  22  is less than 1 mm. The thickness of the second plate  24  is less than 3 mm. A distance between the first plate  22  and the second plate  24  is less than 2 mm. The ring seal  26  can be made of plastic. The ring seal  26  is sandwiched between and adhered to the first plate  22  and the second plate  24 . The closed space  28  can be full of air. 
         [0016]    When the housing of electronic device  100  is assembled, one end of the elastic element  16  is fixed to the first plate  22 . The magnet  14  is sheathed with the elastic element  16 . The plurality of vibration devices  10  is fixed to one side of the first plate  22  away from the second plate  24 . When the housing of electronic device  100  is in use, the elastic element  16  is galvanically producing a magnetic field. The alternating current changes the magnetic field. The magnetic field produced by the alternating current and a magnetic field produced by the magnet  14  are interactional and drive the elastic element  16  to vibrate along a first direction. In an embodiment, the first direction can be substantially perpendicular to the shell  20 . The first plate  22  and the gas within the closed space  28  vibrate via the elastic element  16 . The shell  20  produces sound. 
         [0017]    When amplitude of the elastic element  16  is greater the sound from the shell  20  is louder. The greater the vibration frequency of the elastic element  16  the higher the tone that is generated by the housing. 
         [0018]      FIG. 4  illustrates the housing of the electronic device  100  in a working state. In an embodiment, the housing of electronic device  100  can be a side plate or a cover of an electronic device  200 . The housing of electronic device  100  is fixed to a body of the electronic device  200 . The sound produced by the shell  20  can generate out of the electronic device  200  via an opening  30 . 
         [0019]    The embodiments shown and described above are only examples. Many details are often found in the art such as the other features of a housing of electronic device. Therefore, many such details are neither shown nor described. Even though numerous characteristics and advantages of the present technology have been set forth in the foregoing description, together with details of the structure and function of the present disclosure, the disclosure is illustrative only, and changes may be made in the details, especially in matters of shape, size, and arrangement of the parts within the principles of the present disclosure, up to and including the full extent established by the broad general meaning of the terms used in the claims. It will therefore be appreciated that the embodiments described above may be modified within the scope of the claims.
