Abstract
An acoustic transducer is disposed within a wearable sound device or to be disposed within the wearable sound device. The acoustic transducer includes a first anchor structure and a first flap. The first flap includes a first end and a second end. The first end is anchored by the first anchor structure, and the second end is configured to perform a first up-and-down movement to form a vent temporarily. The first flap partitions a space into a first volume to be connected to an ear canal and a second volume to be connected to an ambient of the wearable sound device. The ear canal and the ambient are connected via the vent temporarily opened.
