Abstract

To surely and accurately position a diaphragm relative to a case, and to improve acoustic characteristics of a flat panel speaker. A boss section 31m of an angular portion 31a is abutted onto a side wall surface 16m of a corresponding corner portion 12a in a side wall 16 of a front case 12 and a boss section 31n is abutted onto a side wall surface 16n of the corner portion 12a, respectively so that a diaphragm 31 is positioned and in such a state, the diaphragm 31 is mounted in the front case 12 via a gasket member 33 adhered onto a mounting plane 17m. An upper part of the diaphragm 31 is formed so that its cross section becomes approximately trapezoidal, and the boss section 31m (31n) is formed so that a contour of its cross section becomes a circular arc of a predetermined curvature in contact with the side wall surface 16m (16n) linearly (or like dots in a plane view).

Description

technical field [0001] The present invention relates to an installation structure and installation method of a flat panel speaker, a vibrating plate, a flat panel speaker, and electronic equipment, for example, to a foldable mobile phone in which a screen member protecting a display panel is used as a vibrating plate for emitting sound Among electronic devices such as the invention, a mounting structure and method of a flat panel speaker of an electronic device in which a vibrating plate serving as a screen component is mounted in a housing, a vibrating plate, a flat panel speaker, and an electronic device. Background technique [0002] In recent years, portable electronic devices such as mobile phones have been widely used due to the high convenience that they can be used even when traveling or going out. In particular, foldable mobile phones that can be opened and closed freely are welcomed by many users because they can be stored compactly. [0003] In addition, a foldab...
