1. A package structure, disposed within a wearable sound device or to be disposed within the wearable sound device, the package structure comprising:
a first substrate; and
a first device, configured to form a first vent and disposed on the first substrate,
wherein the first device comprises:
at least one anchor structure;
a film structure anchored by the at least one anchor structure; and
an actuator, configured to control the film structure to form the first vent temporarily;
wherein the film structure partitions a space into a first volume to be connected to an ear canal of a wearable sound device user and a second volume connected to an ambient of the wearable sound device;
wherein the ear canal and the ambient are connected via the first vent when the first vent is opened;
wherein the film structure comprises a first membrane portion and a second membrane portion, the first membrane portion is controlled to have a first displacement, and the second membrane portion is controlled to have a second displacement;
wherein the actuator comprises a first actuating portion disposed on the first membrane portion and a second actuating portion disposed on the second membrane portion;
wherein the first vent is opened by controlling the first membrane portion via applying a first signal on the first actuating portion and by controlling the second membrane portion via applying a second signal on the second actuating portion, such that a difference between the first displacement and the second displacement is larger than a thickness of the film structure.
