The invention belongs to the field of fans, and particularly relates to a synthetic dual-jet air supply device and method and a bladeless fan thereof.The synthetic dual-jet air supply device comprises a cavity and a vibrating diaphragm, the vibrating diaphragm is arranged in the cavity and divides the cavity into a cavity I and a cavity II which are independent of each other, and the vibrating diaphragm is arranged in the cavity; an air inlet/outlet I communicated with the cavity I is formed in one side, in the downstream direction of the air supply direction, of the outer wall face of the cavity I, the outer wall face of the cavity II is arranged in a Coanda face II mode in the air supply direction, and an air inlet/outlet II communicated with the cavity II is formed in the upstream position, in the air supply direction, of the Coanda face II. The synthetic double-jet air supply device is simple and compact in structure, stable in air source, low in energy consumption and high in safety, and air supply components such as internal motors, turbines and high-speed rotating blades are not needed.
