The invention describes an aerosol generator for inhalation therapy devices, in which an oscillatable assembly, consisting of at least a membrane and an oscillation generator, is mounted in an encapsulating means such that at least the membrane is exposed for the supply of liquid and the generation of an aerosol, whereas the remaining parts of the oscillatable assembly are protected. Mounting occurs by means of a flexible passage such that the oscillatory motions of the oscillatable assembly are not negatively affected.
