1. A hookah device comprising:
a plurality of ultrasonic mist generator devices which are each provided with a respective mist outlet port, wherein each mist generator device comprises:
a mist generator housing which is elongate and comprises an air inlet port and the said mist outlet port;
a liquid chamber provided within the mist generator housing, the liquid chamber containing a liquid to be atomized;
a sonication chamber provided within the mist generator housing;
a capillary element extending between the liquid chamber and the sonication chamber such that a first portion of the capillary element is within the liquid chamber and a second portion of the capillary element is within the sonication chamber;
an ultrasonic transducer having a generally planar atomization surface which is provided within the sonication chamber, the ultrasonic transducer being mounted within the mist generator housing such that the plane of the atomization surface is substantially parallel with a longitudinal length of the mist generator housing, wherein part of the second portion of the capillary element is superimposed on part of the atomization surface, and wherein the ultrasonic transducer vibrates the atomization surface to atomize a liquid carried by the second portion of the capillary element to generate a mist comprising the atomized liquid and air within the sonication chamber; and
an airflow arrangement which provides an air flow path between the air inlet port, the sonication chamber and the air outlet port;
a driver device which is connected electrically to each of the mist generator devices to activate the mist generator devices; and
a hookah attachment arrangement which attaches the hookah device to a hookah, the hookah attachment arrangement having a hookah outlet port which provides a fluid flow path from the mist outlet ports of the mist generator devices and out of the hookah device such that, when at least one of the mist generator devices is activated by the driver device, mist generated by each activated mist generator device flows along the fluid flow path and out of the hookah device to the hookah.
