AEROSOL GENERATOR DEVICE AND NEBULIZER SYSTEM WITH SUCH A DEVICE

The present invention relates to aerosol generation. In order to provide an improved way of protecting and sealing of a vibrating element, an aerosol generator device (10) for a nebulizer is provided. The aerosol generator device comprises a base structure (12), a mesh (14) with a plurality of apertures, and a vibrating element (16). The vibrating element is a piezo-element arranged to generate an oscillating movement. The piezo-element is connected to the base structure to transfer the oscillating movement as vibrational movement to the base structure. Further, the mesh is mounted to the base structure, and the vibrational movement is transferred to the mesh in order to generate a plurality of small droplets to form an aerosol when supplied by a fluid. An encapsulation (18) of the piezo-element is provided to provide a sealing of the piezo-element. The encapsulation is provided as a three-dimensional casing structure rigidly connected to the base structure while leaving a distance space (20) between an inner side of the casing structure and the piezo-element.
