Abstract: An aerosol generator (100) has a vibratable plate (1) with apertures therein and an annular piezo (2) which causes movement of the vibratable plate (1). An annular support member (3) supports the piezo (2) and the vibratable plate (1). A first electrical power conducting pin (10) engages directly with a first, top, surface of the piezo (2). A second electrical power conducting pin (11) indirectly conducts electrical power to a second surface of the piezo (2), by contacting an extension tab (103) of the support member (20), also on its top side. There is a film of cured epoxy adhesive on the tab (103), providing excellent gripping force between the pin (11) and the support (3). The aerosol generator (100) avoids need for soldered joints for electrical contact, and the pins are conveniently mounted parallel to each on the on the same lateral and top side of the piezo and support member. The pins may have multi-point tips (50) for particularly effective electrical contact.
