Abstract
A wearable sound device includes a sound outlet, a side opening, an air pulse generating (APG) device, and an exchanger. The exchanger includes a first opening, a second opening, a third opening, and a fourth opening. The first opening and the second opening are on a first side of the exchanger facing a first chamber, and the third opening and the fourth opening are on a second side of the exchanger facing the sound outlet. The APG device produces a first airflow flowing through a first air pathway between an ambient and the third opening. A second airflow flows through a second air pathway between the fourth opening and the side opening. The first air pathway and the second air pathway are isolated from each other.
