| description | A sound generator includes a piezoelectric vibrator (60) including a piezoelectric element (61), an anchor applying a load to the piezoelectric vibrator (60), and a control unit (130) configured to control an input voltage based on a frequency characteristic, the input voltage being applied to the piezoelectric element (61) as a sound signal. While the load from the anchor is being applied to the piezoelectric vibrator (60), the piezoelectric vibrator (60) deforms in accordance with the input voltage applied to the piezoelectric element (61) from the control unit (130), and deformation of the piezoelectric vibrator (60) vibrates a contact surface (150) contacted by the sound generator, causing sound to be emitted from the contact surface (150). |
