A sound generator includes a housing (), a 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 (). 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.

Sound generator

According to one of aspects, provided is an electronic device including a panel, a piezoelectric elementattached to the panel, and a substrateattached to a main surface of the piezoelectric element. The panelis configured to be deformed due to deformation of the piezoelectric element, and sound is transmitted to an object that is in contact with the deformed panel. The substrateincludes a basemade of resin, and signal linesandlaminated with the baseand connected to the main surface of the piezoelectric element. The substantially the entire main surface of the piezoelectric elementis covered by the base
