Artificial intelligence sound output apparatus, hub for communication network, method of manufacturing the apparatus, and grille for the apparatus

A hub comprising:

• a main body including a housing;
• communication circuitry coupled to the housing of the main body, the communication circuitry exchanging data with another device;
• a base coupled to a lower surface of the housing of the main body;
• a cover including a cover housing, the cover housing including a lower surface coupled to a top of the housing of the main body, and an upper surface to receive a display panel to output visual content associated with the data exchanged with the other device via the communication circuitry;
• and
• a grille formed of an elastically deformable metal sheet, the grille having a surface defining a cylinder with a central cavity, an upper opening and a lower opening, the upper opening of the grille being coupled to the cover housing, the lower opening of the grille being coupled to the base, and the main body being positioned within the central cavity to be encapsulated by the base, the cover, and the grille,
• wherein the cover housing further includes:
• a cylindrical sidewall extending in a vertical direction from the upper surface of the cover housing and positioned above the grille;
• an upper-end holding extension protruding from the sidewall and inserted into the grille from a top side of the grille, the upper-end holding extension being inserted into the upper opening of the grille to contact an inner surface at an upper end of the grille and to maintain a shape of the upper end of the grille as an ellipse;
• and
• a first surface extending from an outer surface of the cylindrical sidewall to the upper-end holding extension so as to be positioned opposite the upper end of the grille when the upper-end holding extension is inserted into the grille.
