A sound generator includes a housing (20), a piezoelectric vibrator (60) including a piezoelectric element (61), at least a portion of the piezoelectric vibrator (60) protruding from the housing (20), and an anchor (10) applying a load to the piezoelectric vibrator (60). A portion or all of the piezoelectric vibrator (60) withdraws into the housing (20) under a force of a predetermined load or greater. While the load from the anchor (10) is being applied to the piezoelectric vibrator (60), the piezoelectric vibrator (60) deforms in response to a sound signal, and deformation of the piezoelectric vibrator (60) vibrates a contact surface contacted by the piezoelectric vibrator (60), causing sound to be emitted from the contact surface.
