Implosive

An implosive is a glottal ingressive plosive sound. The flow of air is created by moving the larynx up and down.

With an implosive, the vocal folds continue to vibrate during the closure. During the closure, the larynx and the vocal folds are lowered, thus enlarging the cavity between the vocal folds and the oral closure. If this lowering happens very quickly, the pressure in the cavity can even drop below that of the external pressure, which at the same time increases the pressure gradient towards the lungs . If the pressure in the cavity remains below the external pressure, air will flow into the cavity from outside ( implosion ) if the seal is released .
