Abstract: The invention provides an aerosol generator (21) for an inhalation device, comprising a vibratable membrane (25), a support member (22), a flexible connector (40) and an annular piezoelectric element (30) having first (33) and second (34) conductive regions on its first (31) and second (32) surfaces. The second conductive region (34) extends onto the first surface of the piezoelectric element to form a contact region (38) so that there are two electrical contacts on the first surface (31). The flexible connector (40) has a surface (42) which is an electrical insulator with first (47) and second (48) conductive regions that correspond to the first conductive region (34) and to the contact region (38) on the piezoelectric element respectively. It has two ‘S’ shaped legs (43, 44) for making electrical connection to a controller that provides a driving current to the piezoelectric element.
