摘要: A package structure includes a cover and a cell disposed within the cover. The cell includes a membrane, an actuating layer and an anchor structure. The membrane includes a first membrane subpart and a second membrane subpart, wherein the first membrane subpart and the second membrane subpart are opposite to each other in a top view. The actuating layer is disposed on the first membrane subpart and the second membrane subpart in the top-view direction. The membrane is anchored by the anchor structure. The first membrane subpart includes a first anchored edge which is fully or partially anchored, and edges of the first membrane subpart other than the first anchored edge are non-anchored. The second membrane subpart includes a second anchored edge which is fully or partially anchored, and edges of the second membrane subpart other than the second anchored edge are non-anchored.
