Abstract
An acoustic transducer is configured to perform an acoustic transformation. The acoustic transducer is disposed within a wearable sound device or to be disposed within the wearable sound device. The acoustic transducer includes at least one anchor structure, a film structure and an actuator. The film structure is disposed within a first layer and anchored by the anchor structure disposed within a second layer. The actuator is disposed on the film structure, and the actuator is configured to actuate the film structure to form a vent temporarily. 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 to be connected to an ambient of the wearable sound device. The ear canal and the ambient are to be connected via the vent temporarily opened when the film structure is actuated.
