Claim:
1. A sound generator comprising: a housing; at least one piezoelectric vibrator including a piezoelectric element, at least a portion of the piezoelectric vibrator protruding from the housing; and an anchor applying a load to the piezoelectric vibrator, wherein a portion or all of the piezoelectric vibrator withdraws into the housing under a force of a predetermined load or greater, while the load from the anchor is being applied to the piezoelectric vibrator, the piezoelectric vibrator deforms in response to a sound signal, and deformation of the piezoelectric vibrator vibrates a contact surface contacted by the piezoelectric vibrator, causing sound to be emitted from the contact surface, and the contact surface is a surface of a component that is separate from the sound generator.
