Abstract: A wireless apparatus having a foldable structure allowing improved antenna condition when opened with improved convenience is disclosed. A first housing and a second housing coupled by a hinge are freely opened and closed around the hinge. An antenna section for use in wireless communication is coupled to the first and second housings by the hinge such that the antenna section is situated at back of the second housing and is freely opened and closed around the hinge with respect to the second housing. A spring force is applied to the antenna section to rotate it in an opening direction. The antenna section is latched by an antenna latch member to be kept in a closed state. When the first housing and the second housing are opened to a predetermined angle, the latch is released to open the antenna section away from the second housing.

Abstract: Upper casing and lower casing of a portable telephone body enclose a body inner cavity in which a printed circuit board is disposed. The printed circuit board has an upper surface thereof on which a speaker body is fixedly mounted by means of soldering. A head portion of the speaker body is fitted with a cap in which a net is secured. An elastic rib formed in the upper portion of the cap and having a triangular cross section is pressed against the upper casing to thereby block entrance of any moisture and dust through a sound aperture without necessity of any adhesive and double-faced adhesive tape. The blocking of entrance of moisture and dust by the utilization of deformation of an elastic material may be applied to electronic parts other than the acoustic parts.
