Abstract
Embodiments of the present disclosure provide an inverter vent and a loudspeaker having the same. Preferably, air flows within the inverted vent in a 360 degrees full-circumferential direction. This design can improve the efficiency of the loudspeaker, reduce the wind noise, and increase the bass ductility.
