main bracket in the video display appliance fig3 shows the video display appliance incorporating the howling phenomena removing apparatus according to one embodiment of the present invention as constructed above and fig4 a and 4b show the apparatus of fig3 to which a loudspeaker is fastened referring to fig3 a and 4b the loudspeaker 6 is not directly fixed to the cabinet 1 but is fastened by a fastening screw 11 to a bracket 10 which is secured with a main circuit board 9 via the vibration absorbing section 200 and the vibration damping section 300 accordingly the vibrations produced from the loudspeaker 6 are firstly absorbed through the vibration absorbing section 200 and then the remaining vibrations are dispersed and damped in the housing 301 of the vibration damping section 300 specifically the vibrations produced from the loudspeaker 6 are transferred to the holder portion 201 through the fixing projections 202 and the fastening screw 8 the vibrations transferred to the holder portion 201 pass through the first supporting ribs 205 extending backwardly from the holder portion 201 and then are propagated along the elastic absorbing rib portion 203 during the propagation through the elastic absorbing rib portion 203 the vibrations are buffered and absorbed by the elasticity of the elastic absorbing rib portion 203 at the same time since the vibration absorbing section 200 is received in the housing 301 of the vibration damping section 300 with the predetermined space the remaining vibrations passing through the vibration.
