Abstract: Disclosed is a planar display assembled and supported through components by making use of adhesive, mainly comprising: a transparent protection board, a display element, and an adhesive. Wherein, said display element is used as a photoelectric element (for example, an LC panel or a backlight module) forming a display. Said display elements can be glued and attached onto said transparent protection board by means of said adhesive such as Velcro, so as to reduce ordinary support elements utilized, thus significantly reducing the volume and weight of said planar display.

Abstract: A structure of speaker for ship having a base seat, a vibration board connected to a vibration shaft, and a coil seat containing a coil, characterized in that a coil housing enclosing an iron block therein, being made from iron is mounted in between the base seat and the coil seat so as to obtain the effect of magnetism concentration, the magnetism is formed when a current is passed through the coil and the magnetism is concentrated at the iron block which in turn attracts the vibration shaft to move downward, and drives, the vibration board to produce vibration, which produce sound.
