A fluid pump for generating a fluid stream includes a first actuator with a first vibration element, a second actuator with a second vibration element, and a power source supplying energy to the first and second actuators. The pump further includes a controller that is connected to the source and controls the source to vary the energy supplied to the first and second actuators. The first and second actuators are arranged opposite to each other so that a first movement direction of the first element is inclined with respect to a second movement direction of the second element. The controller controls the source so that the first element moves towards the second actuator and the second element moves towards the first actuator in a synchronous manner and thereby cyclically soaks in a fluid from the surroundings and ejects the fluid in a directed manner.
