Abstract
An apparatus useful for disseminating volatile liquid such as fragrance into an atmosphere from an evaporating surface adapted to oscillate in the atmosphere. Oscillation is caused and maintained by means of two magnets, one a permanent magnet, the other an electromagnet, one of which is attached to the evaporating surface. The electromagnet is caused to repel the permanent magnet at such points in the oscillation that the oscillation is maintained.
