发明名称 ELECTRONIC APPARATUS AND SHOCK DETECTION METHOD
摘要 In an electronic apparatus equipped with a mechanism for generating a sound and an oscillation, it is possible to detect an imparted shock with high sensitivity. The electronic apparatus includes: an oscillation unit; a piezoelectric element configured to impart an oscillation due to deformation in correspondence with an applied voltage to the oscillation unit, generating a voltage corresponding to deformation due to a shock imparted to the oscillation unit; an induction element for applying an increased voltage to the piezoelectric element; a first switch performing control as to whether or not to supply an electric current from a power source to the induction element; a second switch for effecting connection or disconnection between the induction element and the piezoelectric element; and a shock detection unit configured to detect a shock imparted to the oscillation unit based on the voltage generated in the piezoelectric element.
