Aerosolization using two aerosol generators

An aerosol delivery device comprising:

• a first aerosol generator for generating a first aerosol from a first aerosol precursor and for introducing the first aerosol into a first fluid flow pathway, the first aerosol having particles of a first mass median aerodynamic diameter;
• a second aerosol generator for generating a second aerosol from a second aerosol precursor and for introducing the second aerosol into a second fluid flow pathway;
• the second aerosol having particles of a second mass median aerodynamic diameter, different from the first mass median aerodynamic diameter;
• the first and second fluid flow pathways merging together downstream of the first and second aerosol generators;
• and
• the first fluid flow pathway adjacent to a gas inlet of the device and the second fluid flow pathway adjacent to an aerosol outlet of the device;
• wherein
• the first aerosol generator is configured to agitate the first aerosol precursor or
• the second aerosol generator comprises a piezoelectric element to dispense and aerosolize the second aerosol precursor in the second aerosol generator, wherein the second aerosol precursor is a liquid.
