The present invention relates to an apparatus that removes howling phenomena in a video display appliance capable of absorbing and damping vibrations arising from the output of a loudspeaker to remove the howling phenomena produced by the transfer of the vibrations to a cathode-ray tube. The apparatus includes a vibration-absorbing section mounted on the loudspeaker for absorbing vibrations generated and propagated from the loudspeaker due to the output of the loudspeaker, and a vibration-damping section having a predetermined space for receiving the vibration-absorbing section therein. The vibration-damping section disperses and damps the remaining vibrations passing through the vibration-absorbing section in the space.
