  • Patent number: 8203534
    Abstract: In an electronic apparatus having a touch panel and a chassis for supporting the touch panel, pair of fixing cushions are fixed to the touch panel along edges, which are parallel to each other, of the touch panel. Pair of vibration absorbing cushions are fixed to the chassis parallel to each other. A fixing flame is disposed between the touch panel and the chassis and fixed to the fixing cushions and the vibration absorbing cushions. Thus, the touch panel is supported against the chassis by the fixing cushions, the fixing frame and the vibration absorbing cushions. When the touch panel vibrates, the vibration absorbing cushions prevent transmission of the vibration from the touch panel to the chassis through fixing cushions and the fixing frame. Accordingly, the vibration of the touch panel hardly exercises a harmful influence on components mounted on the chassis.

  • Patent number: 7825778
    Abstract: In an electronic apparatus having a touch panel and pair of vibrating elements for vibrating the touch panel, pair of fixing cushions are fixed on a rear surface of the touch panel along right and left edges of the touch panel. The vibrating elements are fixed to the rear surface of the touch panel along upper and lower edges of the touch panel. The fixing cushions are also fixed to a fixing frames and thereby the touch panel is supported by the fixing frame. The fixing cushions are parallel to each other and stably support the touch panel against the fixing frame. Furthermore, the cushions allow the touch panel to greatly vibrate according to expansion and contraction of the vibrating elements.

  • Publication number: 20060192657
    Abstract: In an electronic apparatus having a touch panel, four fixing cushions are fixed at four corners of a rear surface of the touch panel. The fixing cushions are further fixed to a fixing frame to support the touch panel against to the fixing frame. Pair of vibrating elements are fixed to the rear surface of the touch panel along edges, which are parallel to each other, of the touch panel. The vibrating elements elastically bend the touch panel to cause flexural vibration to the touch panel. The fixing cushions have softness to allow the touch panel to vibrate and hardness to serve as fulcrums of the flexural vibration of the touch panel.
