Flat panel speaker, electronic device having same, and structure and method for mounting same

A structure for mounting a flat panel speaker in an electronic device in which said flat panel speaker to emit sound waves by vibrating a diaphragm is attached to a cabinet of said electronic device, said structure comprising:

• at least one first protruding portion and at least one second protruding portion formed in said cabinet, both being used to place said diaphragm on a putting-face of said cabinet, with said diaphragm positioned relative to said cabinet;
• and
• at least one first struck portion and at least one second struck portion formed in side wall portions of said diaphragm and said diaphragm is positioned relative to said cabinet in a first direction and in a second direction both intersecting each other and approximately parallel to said putting-face of said cabinet;
• wherein, by striking of said first protruding portion against said first struck portion, said diaphragm is positioned relative to said cabinet in said first direction and, by striking of said second protruding portion against said second struck portion, said diaphragm is positioned relative to said cabinet in said second direction.

A diaphragm attached to a cabinet of an electronic device and making up a flat panel speaker for emitting sound waves by being vibrated, said diaphragm comprising:

• at least one first protruding portion and at least one second protruding portion to place said diaphragm on a putting-face of said cabinet, with being positioned relative to said cabinet, when said diaphragm is attached to said cabinet, are formed in side wall portions of said diaphragm;
• wherein said diaphragm is positioned relative to said cabinet in a first direction and in a second direction both intersecting each other and approximately parallel to said putting-face of said cabinet;
• and
• wherein, by striking of said first protruding portion against a first struck portion formed in said cabinet, said diaphragm is positioned relative to said cabinet in said first direction and, by striking of said second protruding portion against a second struck portion formed in said cabinet, said diaphragm is positioned relative to said cabinet in said second direction.
