Abstract: An electronic device that provides a number of function modes and operates by selecting one of the function modes. The device includes an audio output unit and a wireless communication unit that execute functions for the function modes. Moreover, a deformation detecting unit that detects deformation of an exterior housing by an external force and a storage unit that stores a correspondence between a deformation pattern and a response operation registered per function mode. The device also includes an operation determining unit that detects the deformation pattern based on the deformation and a control executing unit that reads a response operation of a current function mode associated with the deformation pattern and controls operation states of the audio output unit and the wireless communication unit.

Abstract: A touch input device includes a touch panel, a press detection signal generating unit and a touch detection signal generating unit. The touch panel is formed by laminating a piezoelectric sensor and a capacitive sensor. The piezoelectric sensor is connected to the press detection signal generating unit, and the capacitive sensor is connected to the touch detection signal generating unit. The piezoelectric sensor includes a piezoelectric film, and first and second press detecting conductors disposed with the piezoelectric film sandwiched therebetween. The piezoelectric film is disposed such that a polarity of electric charges produced by a press in the piezoelectric film, and a polarity of excited electric charges produced in the piezoelectric film when the capacitive sensor detects a touch become reverse polarities.

Abstract: A touch input device includes a touch panel, a push amount calculating unit and a touch detection signal generating unit. The touch panel includes piezoelectric and electrostatic sensors. The piezoelectric sensor outputs to the push amount calculating unit a push signal corresponding to a displacement amount obtained by pushing an operation surface. The electrostatic sensor outputs touch signals, corresponding to a touch and a non-touch, to a touch detection signal generating unit. The touch detection signal generating unit outputs to the push amount calculating unit the touch detection signals binarized according to the touch and non-touch state. The push amount calculating unit integrates differences between push signals and a reference potential during a touch state, generates a push amount detection signal and outputs the push amount detection signal. This unit resets a reference potential during a period in which a touch detection signal indicating a non-touch state is inputted.
