  • Patent number: 11009953
    Abstract: A resin film is disposed facing an upper surface of a diaphragm with a gap interposed therebetween. The gap is provided between a lower surface of the resin film and the upper surface of the diaphragm in a tactile feedback keyboard. Consequently, it is possible to secure a key stroke from the resin film to the upper surface of the diaphragm, and make a user feel a sense of an operation that the user has pushed a key. Further, the gap and the resin film reduces the vibrations from the diaphragm reaching an operation surface. Thus, the user feels the vibrations of the diaphragm via only a finger which has pushed the resin film until the resin film contacts the upper surface of the diaphragm, and the other fingers hardly feel the vibrations.
