Abstract
An audio apparatus includes a housing, a piezoelectric vibration unit provided to the housing and having a piezoelectric element, and a communication unit for receiving an audio signal. When a received audio signal is applied to the piezoelectric element while a load of the audio apparatus is applied to the piezoelectric vibration unit, the piezoelectric element is deformed causing deformation of the piezoelectric vibration unit, whereby a contact surface in contact with the audio apparatus vibrates and generate a sound.
Claims13
An audio apparatus comprising:
- a housing;
- a piezoelectric vibration unit having a piezoelectric element provided to the housing;
- and
- a communication unit configured to receive an audio signal,
- wherein, when a received audio signal is applied to the piezoelectric element while a load of the audio apparatus is applied to the piezoelectric vibration unit, the piezoelectric element is deformed causing deformation of the piezoelectric vibration unit, whereby a contact surface in contact with the audio apparatus is vibrated generating a sound, and
- wherein, in said deformation of the piezoelectric vibration unit, the piezoelectric vibration unit projects outwardly from the housing and retracts inwardly into the housing in response to the received audio signal.
