Title: Grounding structure of the ear phone socket

Description:
BACKGROUND OF THE INVENTION 
     In many electrical utilities, in order to prevent the effects of the electrostatics or the other abnormal electrical ions, it is necessary to add grounding wires for the purpose of discharging. For ordinary audio apparatus, apparently, this kind of grounding structure is more important. However, in most of the audio apparatus, designs related to their ear phone sockets ( 1 ) are shown in FIG. 1, which only have the conventional basic functions, and do not have the related arrangements of grounding structures, thus lead to the shortcomings for usage. 
     OBJECT OF THE INVENTION 
     Owing to this, the present invention mainly is to provide an innovative grounding structure of the ear phone socket for fixing the disadvantages of the conventional products. Now, by fitting with the drawings, the features and effectiveness of the present invention are described as the following:

     DETAILED DESCRIPTION OF THE INVENTION 
     Please refer to those shown in FIG. 2 to FIG. 4, the present invention mainly is set with engaging holes ( 11 ) at both ends of the ear phone socket ( 1 ). Further, a overcoat typed housing ( 2 ) is able to be cover-assembled to a surface of the ear phone socket ( 1 ) with inward slanted clip-assembling edges ( 21 ) set at both side edges of outside housing ( 2 ). Therefore, after the outside housing ( 2 ) is sleeved on the upper portion of the ear phone socket ( 1 ), each clip-assembling edges ( 21 ) immediately are clipped into the engaging holes ( 11 ) to form a effective binding status. 
     After assembling a phone socket ( 1 ) with an outside housing ( 2 ), they are set to the audio apparatus, and the housing ( 2 ) also is the apparatus assembled in the audio and with quite large contact area. Therefore it can obtain the excellent grounding capability and achieve the predicting object of the present invention. 
     As shown in FIG. 5 to FIG. 7, the present invention is able to set a group of flexible wings ( 22 ) which extent in a slanted direction to a central portion of the outside housing ( 2 ). By utilizing the flexible contact body, it will be able to upgrade the grounding effect and thus improve the sound quality of audio apparatus. 
     Please refer to those shown in FIG. 8 to FIG. 10, the present invention also can be set as open hole typed outside housing ( 3 ) for the sleeve-assembling the conventional ear phone sockets ( 1 ) such that the socket poles ( 13 ) are exposed out through the open holes ( 31 ). Further, a metal plate ( 12 ) is set to the other side of the ear phone socket to enhance the grounding capability. 
     Generally speaking, the main characteristic of the present invention is to design a grounding device with the delicate structure which can be easily to be utilized in the ear phone socket. It only needs easy assembly to finish the clip-assembling, and achieve the grounding effect and reduce the electromagnetic radiation. It is obviously provided with the practical value of first inventiveness, thus it fits with the conditions for patent and we file the application according to the law.
