    Abstract: A vibration apparatus and an electronic apparatus including the same are discussed. The vibration apparatus can include a vibration generating part. The vibration generating part can include a plurality of electrode layers, a plurality of vibration layers between the plurality of electrode layers and including a piezoelectric material, a first connection member configured to be electrically connected to an electrode layer of a first group among the plurality of electrode layers, and a second connection member configured to be electrically connected to an electrode layer of a second group among the plurality of electrode layers. Each of the plurality of electrode layers is configured to have a shape, which differs from a shape of each of the plurality of vibration layers, and a size which is smaller than a size of each of the plurality of vibration layers.
