Abstract: The present invention relates to a membrane unit for generating an aerosol in an aerosol therapy device, the membrane unit comprising a membrane (1) having an area (6) comprising a plurality of through-holes for nebulizing a fluid and a flange (7) circumferentially surrounding the area (6), and a substrate (2) having an opening (8) wherein the flange (7) of the membrane (1) is welded to the substrate (2) so that the area (6) is located in the opening (8) wherein the weld (5) comprises at least three discontinuous welds (5c) arranged at a distance from each other a long a circumference of the opening (8) and a first annular weld (5b) circumferentially surrounding the opening (8).

Abstract: The invention relates to an aerosol generator (1), comprising a housing (20, 22), having a first holding member (24, 24?, 24?) and a second holding member (38), and a vibratable element (4) for generating an aerosol. The vibratable element (4) is at least partially accommodated in the housing (20, 22). The vibratable element (4) is contacted by and held between the first and second holding members (24, 24?, 24?; 38). The first holding member (24, 24?, 24?) is less flexible than the second holding member (38). Further, the invention relates to an aerosol delivery device comprising the aerosol generator (1).

Abstract: The invention relates to a method of manufacturing a vibratable head (1) for an aerosol generator (2), the vibratable head (1) comprising a support member (4), a vibratable membrane (6) supported by the support member (4) and a vibrator (8) configured to vibrate the vibratable membrane (6). The method comprises the steps of providing the support member (4), roughening a surface portion (10) of the support member (4) by laser structuring, applying an adhesive (9) to at least a part of the roughened surface portion (10) of the support member (4) and attaching at least one element to the support member (4) by at least a portion of the adhesive (9). Further, the invention relates to a vibratable head (1) manufactured by this method, an aerosol generator (2) comprising such a vibratable head (1) and a method of manufacturing such an aerosol generator (2).
