The mobile terminal apparatus of the present invention includes a housing having an opening section in which an accommodated object is fitted; a lid covering the opening section, the lid having a protrusion which surrounds the opening section and shields the accommodated object from water, on a surface facing the accommodated object; and a cover covering the lid, the cover being attached to the housing to press the lid onto the housing. When the cover is attached to the housing, the protrusion of the lid surrounds the opening section and is pressed onto the housing by the cover, so that the accommodated object can be reliably shielded from water.

Water-shielding type mobile terminal apparatus

A terminal is formed by plating a terminal substrate in which a first material capable of being plated and a second material incapable of being plated are two-color molded. For example, by two-color molding an ABD resin and a PC resin to form a terminal substrate and plating the terminal substrate, a terminal having a conductive part corresponding to the ABS resin and a nonconductive part corresponding to the PC resin is obtained.

Terminal and mobile terminal apparatus

A waterproof protection cover and an acoustic component are each disposed inside a portable device provided with a chassis having one or more holes. The acoustic component emits sound. For the acoustic component, an acoustic component having a maximum acoustic output between 0.25 W or more and 0.8 W or less is used. The waterproof protection cover secures an area of 114 mmor more as an acoustically transparent portion for transmitting acoustic energy from the acoustic component.

Portable device, acoustic component disposition method and acoustic component assembly

This optical-fiber holder comprises an annular optical-fiber winding framework. The optical-fiber winding framework includes an optical-fiber winding frame portion and a base portion provided as a turning axle of the optical-fiber winding framework. The optical-fiber winding frame portion has an optical-fiber containing groove formed along a periphery thereof. The base portion has an opening penetrating into an interior thereof and communicating with the optical-fiber containing groove at both ends. An optical fiber is wound and held in the interior of the base portion and the optical-fiber containing groove.
