     Referring now to  FIG. 6 , the fitting members  58  are placed such that the bases  5820  thereof face the respective bosses  5204  of the frame  52 , and are fitted to the bosses  5204  such that the bosses  5204  are received in the respective boss insertion holes  5810  of the fitting members  58 . 
     Subsequently, with the bases  5820  of the fitting members  58  being in contact with the rear face of the cover  56 , screws N 2  are screwed into the screw holes  5206  until the heads of the screws N 2  come into contact with the respective flanges  5808 . Thus, the fitting members  58  are secured to the frame  52 . 
     Cushion Member  42   
     Referring to  FIGS. 5 ,  7 , and  16 , the cushion member  42  is provided on the frame  52  so as to be electrically continuous with the grille body  50 . 
     The cushion member  42  is made of a conductive, elastic material. The material may be any of various common materials. 
     Referring to  FIGS. 5 and 16 , the cushion member  42  of this embodiment has an elongated columnar shape with a rectangular cross section. 
     Referring to  FIG. 16 , the connection tab  5010  of the grille body  50  is bent beforehand so as to be placed in the space surrounded by the receiving wall member  5220  of the frame  52 . In this state, the cushion member  42  is fitted into the space surrounded by the receiving wall member  5220 . The cushion member  42  is bonded to the receiving wall member  5220  with adhesive or the like. 
     Thus, the cushion member  42  comes into contact with the connection tab  5010  and accordingly becomes electrically continuous with the grille body  50 . 
     Conductive Member  44   
     Referring to  FIGS. 5 and 7 , the conductive member  44 , which is grounded inside the electronic-apparatus housing  11 , becomes electrically continuous with the grille body  50  through the cushion member  42  when the frame  52  is attached to the electronic-apparatus housing  11  (precisely, to the engaging rims  3204  of the fitting portions  32 ). 
     The conductive member  44  of this embodiment is made of metal. 
     The conductive member  44  has an elongated shape, with a portion thereof in the longitudinal direction forming a rod  4402  having a circular cross section and the rest forming an external thread  4404  provided coaxially with the rod  4402  and having a smaller diameter than the rod  4402 . 
     The rod  4402  has at the tip thereof a fitting hole  4406  extending coaxially with the rod  4402  and having a hexagonal cross section. Thus, the fitting hole  4406  can receive a hexagonal wrench. 
     The rod  4402  has at the base thereof a flange  4407 . 
     The external thread  4404  can be screwed into a screw hole  4610  provided in the baffle  46 . 
     Referring to  FIGS. 5 ,  7 , and  10 , the conductive member  44 , oriented such that the tip of the rod  4402  thereof faces the conduction opening  34 , is secured to the baffle  46  by having the external thread  4404  thereof screwed into the screw hole  4610  of the baffle  46 . 
     With the conductive member  44  having such a shape, the conductive member  44  can be easily attached to the electronic-apparatus housing  11  (precisely, to the baffle  46 ), leading to a reduction in the manufacturing cost of the electronic apparatus  10 . 
     Attachment of Speaker Grille  40   
     The attachment of the speaker grille  40  will now be described. 
     After the securing of the cushion member  42  to the speaker grille  40  that has been assembled as described above, referring now to  FIGS. 18 and 19 , the speaker grille  40  is positioned such that the fitting members  58  face the respective fitting portions  32  of the right member  16 D (the left member  16 C) of the center panel  16 . 
     Then, the fitting members  58  are placed into the respective recesses  3202  of the fitting portions  32 , and the rear face of the speaker grille  40  (the rear face of the cover  56 ) is pressed against the front face of the right member  16 D (the left member  16 C). 
     Subsequently, the speaker grille  40  is moved downward so that the engagement grooves  5804  of the fitting members  58  engage with the engaging rims  3204  of the fitting portions  32 , respectively. This causes the cushion member  42  to come into contact with the tip of the conductive member  44 , as shown in  FIGS. 5 ,  7 , and  22 . 
     Thus, the speaker grille  40  is attached to the electronic-apparatus housing  11 , with the grille body  50  being grounded through the cushion member  42  and the conductive member  44 . 
     As described above, to engage the engagement grooves  5804  of the fitting members  58  with the engaging rims  3204  of the fitting portions  32 , respectively, the fitting members  58  are first placed into the respective recesses  3202  and then the speaker grille  40  is moved downward. This engaging process may alternatively be performed in the following manner. 
     Referring to  FIG. 20 , the guide surfaces  5806  of the fitting members  58  are first pressed against the engaging rims  3204  of the fitting portions  32 , respectively, from the front. 
     In this state, the speaker grille  40  is pushed into the right member  16 D (the left member  16 C). Accordingly, referring to  FIG. 21 , the guide surfaces  5806  that are being pressed against the engaging rims  3204  undergo elastic deformation. Consequently, the engagement grooves  5804  engage with the engaging rims  3204 , respectively. 
     Also in this alternative process, the cushion member  42  comes into contact with the base of the conductive member  44 , whereby the grille body  50  is grounded through the cushion member  42  and the conductive member  44 . 
     Thus, the attachment of the speaker grille  40  is completed, as shown in  FIG. 1 . 
     To remove the speaker grille  40  from the electronic-apparatus housing  11 , the speaker grille  40  is moved upward, whereby the engagement between the engagement grooves  5804  of the fitting members  58  and the engaging rims  3204  of the fitting portions  32  is released first. Subsequently, the speaker grille  40  is moved frontward. 
     To summarize, according to the foregoing embodiment of the present invention, attaching the grille body  50  and the frame  52  to the electronic-apparatus housing  11  (precisely, to the engaging rims  3204  of the fitting portions  32 ) makes the grille body  50  grounded through the cushion member  42  and the conductive member  44 . 
     In the case where a grille body that is made of a conductive material, such as metal, for aesthetic texture and appearance is removably provided on an electronic-apparatus housing, the configuration described in the foregoing embodiment is advantageous in that the grille body  50  is assuredly grounded and electrostatic charging is prevented. 
     Moreover, in the case where a user of an electronic apparatus desires to change the appearance of the electronic apparatus by changing a grille body for another one among various kinds of grille bodies, the configuration described in the foregoing embodiment can eliminate annoying work including reconnection of a grounding lead wire from one grille body to another. Accordingly, the usability of the electronic apparatus is advantageously improved, together with the commercial value thereof. 
     While the embodiment described above concerns the case where the electronic apparatus  10  is a television receiver or a display apparatus, the present invention may also be applied to a wide variety of electronic apparatuses including speakers. 
     The present application contains subject matter related to that disclosed in Japanese Priority Patent Application JP 2008-206635 filed in the Japan Patent Office on Aug. 11, 2008, the entire content of which is hereby incorporated by reference.
