Abstract: A bottom member includes a light-absorbing element; a top coupling layer disposed on the light-absorbing element; a first buffer element disposed under the light-absorbing element, where a first opening is defined in the first buffer element; a filling layer disposed in the first opening; and a vibrating acoustic element disposed below the first buffer element, where the vibrating acoustic element overlaps with the first opening and the light-absorbing element when viewed from a top, and the vibrating acoustic element is coupled with the first buffer element via the filling layer.
