Abstract

See full text

A sound generator includes at least one piezoelectric vibrator including a piezoelectric element, a vibration unit in one of a non-contact state not contacting the at least one piezoelectric vibrator and a contact state contacting the at least one piezoelectric vibrator. While in the contact state, the at least one piezoelectric vibrator generates vibration in response to a signal, and causes a contact surface contacted by the vibration unit to vibrate and generate a sound to be emitted from the contact surface. The sound generator can detect driving allowed and driving denied states, and control application of a sound signal in accordance with the two states to the piezoelectric element.
