  • Patent number: 8494577
    Abstract: An electronic device 100 includes a signal converter 110 and a housing 120. The signal converter has a diaphragm 111 and, when one of an acoustic signal and an electric signal is inputted, converts the inputted signal into the other signal by the vibrations of the diaphragm. The housing is provided with an internal space SPD. The housing holds the signal converter in the internal space. The housing is provided with an opening 121. The housing has a bulkhead 122 dividing the internal space into plural division spaces including a first division space SPD1 and a second division space SPD2. The diaphragm configures at least part of a bulkhead forming the first division space. The housing is provided with a first communicating path that makes the first division space communicate with the opening, and a second communicating path that makes the second division space communicate with the opening.

  • Publication number: 20120287566
    Abstract: A display panel is expandable without increasing the size and without reducing the sealing function including the waterproof function while the display panel is prevented from deforming due to a strong sealing force. A housing includes first and second housing members. The former includes a wall surrounding a display-panel-holding-space to hold a display panel being a holding target. The latter closes an opening of the display-panel-holding-space whose opening edge is an end face of the wall by engaging the end face of the wall. A space around the opening of the display-panel-holding-space is formed in a border region including a contacting part or a connecting part of the wall and the second housing member. An elastic member is arranged in the space. An edge part of the display panel is arranged closer to an edge face opposite side to the end face of the wall than the elastic member.

  • Patent number: 7742791
    Abstract: In integrally forming a positioning convexity on an inner surface of a case, breakage during a fall and the like is prevented by increasing the strength of the positioning convexity without causing a defective appearance during the molding of the case. In performing the positioning of a top cover and a built-in frame by fitting together a positioning concavity formed in the built-in frame and a positioning convexity which is integrally formed on an inner surface of the top cover, the positioning convexity is formed from a rib in the shape of a box or the like. To lessen stress concentration, the positioning convexity is disposed in the vicinity of a screw fixing section. To improve assemblability, a curved surface or an inclined surface which guides the fitting into the positioning concavity is formed at a leading end of the rib which constitutes the positioning convexity.

  • Patent number: 7477737
    Abstract: An electronic apparatus with a detachable cover is proved. The present invention is possible to maintain a satisfactory outward appearance when the cover is attached to the apparatus, and to improve the structural body of the apparatus in terms of strength and formability without having to diminish the inner space for built-in mounting components.
