INPUT APPARATUS FOR PORTABLE TERMINAL AND METHOD FOR MANUFACTURING THE SAME

摘要

An input apparatus for a portable terminal and a method for manufacturing the same are provided to detect not only the intensity and the direction of contact force but also the on/off signal. Terminals(101,102) are formed on a printed circuit board(100). A supporting part(110) is formed on the top of the printed circuit board. The supporting part comprises penetration holes(111,112). A structure with membrane(130) is formed with the flat type on the top of the supporting part. The structure with membrane comprises membrane regions(131,132). Strain gages(151,152) are formed on the top of the membrane regions of the structure with membrane. Strain gages are electrically connected with the terminals of the printed circuit board. Load blocks(210,220) are formed on the top of the membrane regions of the structure with membrane.
