1. A wearable sound device, comprising:
a sound outlet and a side opening;
an air pulse generating (APG) device, configured to produce an audible sound via generating a plurality of air pulses; and
an exchanger;
wherein the APG device produces a first airflow flowing via a first air pathway through the exchanger between an ambient and the sound outlet;
wherein a second airflow flows via a second air pathway through the exchanger between the sound outlet and the side opening;
wherein the first air pathway and the second air pathway are isolated from each other.
