Abstract:
Provided is a vibration panel including an inner member, a first outer member, a second outer member, a piezoelectric actuator, an actuator bonding layer, and a filler. The inner member includes first and second main surfaces. The first outer member includes third and fourth main surfaces, the third main surface including a first region and a second region. The second outer member includes fifth and sixth main surfaces, the fifth main surface including a third region and a fourth region. The piezoelectric actuator causes vibration. The actuator bonding layer is disposed between the piezoelectric actuator and the second region and bonds the piezoelectric actuator to the second region. The filler fills a space between the second region and the fourth region and covers the piezoelectric actuator.
