1. An input apparatus comprising:
- a touch sensor configured to detect a touch input, the touch sensor disposed on the input apparatus via a plurality of supports and the touch sensor configured to bend in response to the touch input;
piezoelectric elements directly mounted on the touch sensor at a respective spaced distance from each one of the plurality of supports, each of the piezoelectric elements having one end mounted on the touch sensor and the other end opened, the piezoelectric elements are disposed at two sides opposite to each other and at least one side orthogonal to the two sides in a peripheral region on the touch sensor and the piezoelectric elements are not supported from inside of the housing; and
a control unit configured to detect a pressure load on a touch face of the touch sensor based on an output signal of the piezoelectric elements caused by the bending of the piezoelectric elements in response to the touch input on the touch face and, when the pressure load detected satisfies a standard to provide a tactile sensation, to drive the piezoelectric elements such that the tactile sensation is provided to an object pressing the touch face.
