PROBLEM TO BE SOLVED: To make the size of the electronic device utilizing the piezoelectric effect of the piezoelectric element small and to reduce trouble of the switching operation. SOLUTION: A piezoelectric element 11 built in the electronic device is provided with an electrode 14 used to exert shock to the piezoelectric element 11 and to provide an output of an electromotive force generated due to distortion and in the case of exerting shock to the electronic device incorporating the piezoelectric element 11, when the piezoelectric element 11 is distorted by the shock exerted to the built-in piezoelectric element 11, an electromotive force produced in the piezoelectric element 11 is outputted to control the operation of each function. |
