Droplet generation apparatus

A droplet generation apparatus, applicable for a nebulizer, and the droplet generation apparatus comprising:

• a vibratable member having a first through hole;
• a fastening plate combined with the vibratable member;
• a nozzle disc disposed between the vibratable member and the fastening plate, and having a plurality of apertures facing the first through hole;
• and
• a housing for covering up the combination of the vibratable member, the nozzle disc and the fastening plate;
• wherein the fastening plate includes a hollow protrusion from a plane behind the nozzle disc, whereby when the fastening plate is combined with the nozzle disc, an accommodation space is formed by the hollow protrusion and the nozzle disc.
