    Abstract: A method relates to manufacturing a sound output apparatus. The method includes processing a flat metal plate to have a shape with through-holes; forming a cylindrical grille by bonding two sides of the processed flat metal panel to each other so that a side corresponding to the upper end of the main shape forms an upper end of the grille and a side corresponding to the lower end of the main shape forms a lower end of the grille. The upper end of the grille is deformed to correspond to a shape of a cover by inserting the cover into an opening formed in an upper surface of the grille. A lower end of the grille is deformed to correspond to a shape of the lower-end holding portion formed in the base, by inserting the lower-end holding portion into a lower opening formed in the grille.

    Abstract: A hub comprises a main body with a speaker; a communication module included in the main body; a window formed of a transparent material; a display panel for displaying a screen based on information exchanged via the communication module; and a cover housing coupled to a top of the main body and having a display panel and an opening at an upper surface thereof. The window is provided on an upper surface of the display panel, wherein a normal vector with respect to a predetermined plane in which the opening falls is at an acute angle relative to a horizontal plane, and a vector acquired by orthogonally projecting the normal vector with respect to the horizontal plane faces forward. A portion of the inner surface of the cover housing is parallel with the normal vector, and the window is provided so that an upper surface faces the direction of the normal vector.
