Abstract
A loudspeaker case structure for a video display appliance capable of damping and absorbing vibrations arising from the output of a loudspeaker to remove the howling phenomena produced on a cathode-ray tube by the transfer of the vibrations to the cathode-ray tube. The loudspeaker case structure includes a housing having a predetermined space for receiving the loudspeaker therein, dispersing and damping the vibrations from the loudspeaker through the space, and a supporting section, extending from the housing, for supporting and fixing the housing to a main bracket of a cabinet and absorbing the remaining vibrations passing through the housing.
