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.
